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 {/*** 多参数封装到map中，多条件查询* @param map* @return*/List<User> findByConditionByMap(HashMap<String, Object> map);}

2.UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.william.dao.UserMapper"><!--多参数封装到map中，多条件查询--><select id="findByConditionByMap" parameterType="map" resultType="user">select * from user where username like "%"#{username}"%" and sex=#{sex}limit #{startIndex},#{pageSize}</select>
</mapper>

3.TestCrud测试类

import com.william.domain.User;

import java.util.List;/*** @author ：lijunxuan* @date ：Created in 2019/7/12  10:16* @description ：* @version: 1.0*/
public class TestCrud {/*** 多参数封装到map中，多条件查询* @throws IOException*/@Testpublic void findByConditionByMap() 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();HashMap<String, Object> map = new HashMap<>();map.put("username","a");map.put("sex","男");map.put("startIndex",0);map.put("pageSize",6);List<User> userMapperByConditionByMap = userMapper.findByConditionByMap(map);for (User user1 : userMapperByConditionByMap) {System.out.println(user1);}sqlSession.close();}
}
