快速上手SSM(Spring,SpringMVC,Mybatis)框架整合项目

快速上手SSM(Spring,SpringMVC,Mybatis)框架整合项目

环境要求：

• IDEA
• MySQL 8.0.25
• Tomcat 9
• Maven 3.6

数据库环境：
创建一个存放书籍数据的数据库表

CREATE DATABASE `ssmbooks`;

USE `ssmbooks`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT "书id",
`bookName` VARCHAR(100) NOT NULL COMMENT "书名",
`bookCounts` INT(11) NOT NULL COMMENT "数量",
`detail` VARCHAR(200) NOT NULL COMMENT "描述",
KEY `bookID` (`bookID`)
);

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,"Java",1,"从入门到放弃"),
(2,"MySQL",10,"从删库到跑路"),
(3,"Linux",5,"从进门到进牢");

基本环境搭建：
1、新建一Maven项目！ssmbooks ， 添加web的支持
2、导入相关的pom依赖！

            <version>1.18.2</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>

3、Maven资源过滤设置

<!--静态资源导出问题-->
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

4、建立基本结构和配置框架！

• com.bai.pojo
• com.bai.dao
• com.bai.service
• com.bai.controller
• mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

• applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

Mybatis层编写

1、数据库配置文件 database.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbooks?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

2、IDEA关联数据库
3、编写MyBatis的核心配置文件

<!--    配置数据源  交给spring去做-->

<!--    别名-->
    <typeAliases>
        <package name="com.bai.pojo"/>
    </typeAliases>

<!--    注册BookMapper.xml-->
    <mappers>
        <mapper class="com.bai.dao.BookMapper"></mapper>
    </mappers>

4、编写数据库对应的实体类 com.bai.pojo.Books
使用lombok插件！

package com.bai.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {

    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;

}

5、编写Dao层的 Mapper接口！

package com.bai.dao;

import com.bai.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {
        //    添加一本书
        int addBook(Books books);
        //    删除一本书
        int deleteBookById(@Param("bookId") int id);
        //    更新一本书
        int updateBook(Books books);
        //    查询一本书
        Books queryBookById(@Param("bookId") int id);
        //    查询全部的书
        List<Books> queryAllBook();
        //    通过名字查询书籍
        List<Books> queryBookByName(@Param("BookName") String BookName);
}

6、编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.bai.dao.BookMapper">
<!--        添加一本书-->
    <insert id="addBook" parameterType="com.bai.pojo.Books">
        insert into ssmbooks.books ( bookName, bookCounts, detail)
        values (#{bookName},#{bookCounts},#{detail})
    </insert>
<!--    删除一本书-->
    <delete id="deleteBookById" parameterType="int">
        delete from ssmbooks.books where bookID = #{bookId}
    </delete>
<!--    更新一本书-->
    <update id="updateBook" parameterType="com.bai.pojo.Books">
        update ssmbooks.books set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID}
    </update>
<!--    通过id查询书籍-->
    <select id="queryBookById" resultType="com.bai.pojo.Books">
        select * from ssmbooks.books where bookID=#{bookId}
    </select>
<!--    查询全部的书-->
    <select id="queryAllBook" resultType="com.bai.pojo.Books">
        select * from ssmbooks.books
    </select>
<!--    通过名字查询书籍-->
    <select id="queryBookByName" resultType="com.bai.pojo.Books">
        select * from ssmbooks.books where bookName  like concat("%",#{BookName},"%")
    </select>
</mapper>

7、编写Service层的接口和实现类
接口：

package com.bai.service;

import com.bai.pojo.Books;

import java.util.List;

public interface BookService {
    //    添加一本书
    int addBook(Books books);
    //    删除一本书
    int deleteBookById(int id);
    //    更新一本书
    int updateBook(Books books);
    //    查询一本书通过id
    Books queryBookById(int id);
    //    查询全部的书
    List<Books> queryAllBook();
    //    查询一本书通过名字
    List<Books> queryBookByName(String BookName);
}

实现类：

package com.bai.service;

import com.bai.dao.BookMapper;
import com.bai.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

import java.util.List;
@Service("BookServiceImpl")
public class BookServiceImpl implements BookService{

    //service层调dao层： 组合dao
    @Autowired
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }

    public List<Books> queryBookByName(String BookName) {
        return bookMapper.queryBookByName(BookName);
    }
}

OK，到此，底层需求操作编写完毕！

Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；
2、我们去编写Spring整合Mybatis的相关的配置文件；spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd 
       http://www.springframework.org/schema/context 
       https://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 配置整合mybatis -->
<!--    1.关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>

<!--    2.数据库连接池  dbcp: 半自动化操作，不能自动连接    c3p0：自动化操作（自动化的加载配置文件，并且可以自动设置到对象中！）-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

<!--    3.sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
<!--        绑定mybatis的配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

<!--    配置dao接口扫描包，动态的实现了dao接口可以注入到Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--        1.注入 sqlSessionFactory-->
<!--       继承就使用： sqlSessionFactoryBeanName   私有化就使用：sqlSessionTemplateBeanName-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!--        2.扫描dao包-->
        <property name="basePackage" value="com.bai.dao"/>
    </bean>

</beans>

3、Spring整合service层

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

<!--    1.扫描service下的包-->
    <context:component-scan base-package="com.bai.service"/>

<!--    2.将我们所有的业务类，注入到spring中，可以通过配置，或注解实现自动装配-->
<!--    <bean id="BookServiceImpl" class="com.bai.service.BookServiceImpl">-->
<!--        <property name="bookMapper" ref="bookMapper"/>-->
<!--    </bean>-->

<!--    3.声明式事务配置-->
    <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--        注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>

<!--    4.aop事务支持-->


</beans>

Spring层搞定！再次理解一下，Spring就是一个大杂烩，一个容器！对吧！

SpringMVC层

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!--DispatcherServlet-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！-->
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--乱码配置：过滤器-->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--Session过期时间-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

2、spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       https://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!--    1.注解驱动-->
    <mvc:annotation-driven/>
<!--    2.静态资源过滤-->
    <mvc:default-servlet-handler/>
<!--    3.扫描包：controller-->
    <context:component-scan base-package="com.bai.controller"/>
<!--    4.配置jsp 显示ViewResolver视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

3、Spring配置整合文件，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>

</beans>

Controller 和 视图层编写
**1、BookController 类编写 **

package com.bai.controller;


import com.bai.pojo.Books;
import com.bai.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    //controller层调service层
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    //查询全部的书籍，并且返回到一个数据展示页面
    @RequestMapping("/allbook")
    public String list(Model model) {
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list", list);
        return "allbook";
    }

//    跳转到添加书籍页面
    @RequestMapping("/toAddBook")
    public String toAddPaper() {
        return "addBook";
    }
    //添加书籍的请求
    @RequestMapping("/addBook")
    public String addBook(Books books){
        System.out.println("Books=>:"+books);
        bookService.addBook(books);
        return "redirect:/book/allbook";
    }

    //跳转到修改书籍页面
    @RequestMapping("/toUpdate")
    public String toUpdatePaper(int id,Model model){
        Books books = bookService.queryBookById(id);
        model.addAttribute("QBook", books);
        return "updateBook";
    }

    //修改书籍请求
    @RequestMapping("/updateBook")
    public String UpdateBook(Books books,Model model) {
        System.out.println("UpdateBook=>:"+books);
        bookService.updateBook(books);
//        出现的问题：我们提交了修改的SQL请求，但是修改失败。
//        我们看一下sql语句，能否执行成功？ 执行失败：发现sql语句需要传递一个id进行修改
//        Books books1 = bookService.queryBookById(books.getBookID());
//        model.addAttribute("books1", books1);
        return "redirect:/book/allbook";
    }

    //删除书籍请求
    @RequestMapping("/del/{bookid}")
    public String DeleteBook(@PathVariable("bookid") int id) {
        bookService.deleteBookById(id);
        return "redirect:/book/allbook";
    }

    //通过名字查询书籍请求
    @RequestMapping("/queryBook")
    public String queryBook(String queryBookName,Model model) {
        List<Books> list = bookService.queryBookByName(queryBookName);
        model.addAttribute("list", list);
        if (list.size()==0){
            model.addAttribute("msg", "未查到数据");
        }
        return "allbook";
    }
}

2、编写首页 index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>首页</title>
  </head>
  <style type="text/css">
    a {
      text-decoration: none;
      color: black;
      font-size: 18px;
    }
    h3 {
      width: 180px;
      height: 38px;
      margin: 100px auto;
      text-align: center;
      line-height: 38px;
      background: deepskyblue;
      border-radius: 4px;
    }
  </style>
  <body>
  <h3>
    <a href="${pageContext.request.contextPath}/book/allbook">进入书籍页面</a>
  </h3>
  </body>
</html>

3、书籍列表页面 allbook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>书籍列表</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>

            <table class="table table-hover table-striped">
                <thead>
                <tr>

                <tbody>
                <c:forEach var="book" items="${requestScope.get("list")}">
                    <tr>
                        <td>${book.getBookID()}</td>
                        <td>${book.getBookName()}</td>

            </table>
        </div>
    </div>
</div>

</body>
</html>

5、添加书籍页面：addBook.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>新增书籍</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>新增书籍</small>
                </h1>
            </div>
        </div>
    </div>
    <form action="${pageContext.request.contextPath}/book/addBook" method="post">
        书籍名称：<input type="text" name="bookName"><br><br><br>
        书籍数量：<input type="text" name="bookCounts"><br><br><br>
        书籍详情：<input type="text" name="detail"><br><br><br>
        <input type="submit" value="添加">
    </form>

</div>

</body>
</html>

7、修改书籍页面 updateBook.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <<title>修改信息</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>修改信息</small>
                </h1>
            </div>
        </div>
    </div>

    <form action="${pageContext.request.contextPath}/book/updateBook" method="post">
        <%--出现的问题：我们提交了修改的SQL请求，但是修改失败。
        我们看一下sql语句，能否执行成功？ 执行失败：发现sql语句需要传递一个id进行修改--%>
<%--        前端传参隐藏域--%>
        <input type="hidden" name="bookID" value="${QBook.getBookID()}"/>
        书籍名称：<input type="text" name="bookName" value="${QBook.getBookName()}"/>
        书籍数量：<input type="text" name="bookCounts" value="${QBook.getBookCounts()}"/>
        书籍详情：<input type="text" name="detail" value="${QBook.getDetail() }"/>
        <input type="submit" value="提交"/>
    </form>

</div>

</body>
</html>
