实体对象转QueryWrapper 便捷实现条件查询

mybatis plus中提供了QueryWrapper做条件查询，

方法定义是public Children eq(boolean condition,R column,java.lang.Object val)

参数:condition – 执行条件；column – 字段；val – 值

我们通常是这样写的，

 1    public IhTimeSchedule  getTimeSchedule(String serviceCode,String appointDate, String noonType,
 2                                            String appointTimeInterval, String deptCode, String doctorCode,
 3                                            String clinicTypeCode,String serviceType) {
 4         QueryWrapper<IhTimeSchedule> wrapper=new QueryWrapper<IhTimeSchedule>()
 5                 .eq("DEPT_CODE",deptCode)
 6                 .eq("SERVICE_CODE",serviceCode)
 7                 .eq(StringUtils.isNotBlank(doctorCode),"DOCTOR_CODE",doctorCode)
 8                 .eq("CLINIC_DATE",appointDate+" 00:00:00")
 9                 .eq(StringUtils.isNotBlank(noonType),"NOON_TYPE",noonType).
10                 eq(StringUtils.isNotBlank(appointTimeInterval),"TIME_DIVISION",appointTimeInterval).
11                 eq("CLINIC_TYPE_CODE",clinicTypeCode);
12         IhTimeSchedule schedule = scheduleMapper.selectOne(wrapper);
13         return  schedule;
14     }
