Mybatis多条件直接查询Param注解版

1.UserMapper接口

package com.william.dao;

import com.william.domain.QueryValueObject;
import com.william.domain.User;

import java.util.List;

public interface UserMapper {
 /**
     * 多条件直接查询Param注解版
     * @param username
     * @param sex
     * @param startIndex
     * @param pageSize
     * @return
     */
    public List findByManyConditionByParam(@Param("username") String username, @Param("sex") String sex, @Param("startIndex")Integer startIndex,@Param("pageSize") Integer pageSize);
}

2.UserMapper.xml

    
    
        select * from user where username like "%"#{username}"%" and sex=#{sex}
       limit #{startIndex},#{pageSize}
    

3.TestCrud测试类

package com.william;

import com.william.dao.UserMapper;
import com.william.domain.QueryValueObject;
import com.william.domain.User;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import javax.annotation.Resource;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;

public class TestCrud {
 
  /**
     * Mybatis多条件直接查询Param注解版
     * @throws IOException
     */
    @Test
    public void findByManyConditionByParam() throws IOException {
        InputStream inputStream = Resources.getResourceAsStream("Mybatis-configuration.xml");
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();
        //获取某接口的动态代理对象（获取某接口的一个实现类）
        UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
        QueryValueObject queryValueObject = new QueryValueObject();
        List userMapperByConditionByMap = userMapper.findByManyConditionByParam("a","男",0,7);
        for (User user1 : userMapperByConditionByMap) {
            System.out.println(user1);
        }
        sqlSession.close();
    }
}
