SpringBoot 整合 Shiro 实现登录拦截
一、搭建一个SpringBoot 项目。
二、导入shiro 相关坐标:
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.7.1</version>
</dependency>
三、与启动类同目录创建config 包:
实现抽象类AuthorizingRealm 中的方法:
package com.itmao.config;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
//from fhadmin.cn
public class UserRealm extends AuthorizingRealm {
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
System.out.println("执行了doGetAuthorizationInfo方法");
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
return null;
}
}
编写配置类:
package com.itmao.config;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.LinkedHashMap;
import java.util.Map;
//from fhadmin.cn
@Configuration
public class ShiroConfig {
// ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
// 设置安全管理器
shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
// 设置shiro内置过滤器
Map<String,String> filterMap = new LinkedHashMap<>();
/*
map 中value 的意义
* anon: 无需认证就可以访问资源;
* authc:必须认证后才能访问资源;
* user:必须拥有“记住我”功能才能访问资源;
* perms:拥有对某个资源的权限才能访问资源;
* role:拥有某个角色权限才能访问资源
* **/
filterMap.put("/user/*","authc");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
// 设置登录页面url
shiroFilterFactoryBean.setLoginUrl("/toLogin");
return shiroFilterFactoryBean;
}
// DefaultWebSecurityManager
@Bean
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("getUserRealm") UserRealm userRealm){
DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
// 关联UserRealm
defaultWebSecurityManager.setRealm(userRealm);
return defaultWebSecurityManager;
}
// 创建 realm 对象,需要自定义类
@Bean
public UserRealm getUserRealm() {
return new UserRealm();
}
}
四、编写测试页面和页面跳转的Controller。
上面设置user 目录下所有资源的访问均需认证后才可访问,未认证访问时,会自动跳转到登录页面,即表示登录拦截成功。
