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 {/*** 多條件直接查詢Param注解版* @param username* @param sex* @param startIndex* @param pageSize* @return*/public List<User> findByManyConditionByParam(@Param("username") String username, @Param("sex") String sex, @Param("startIndex")Integer startIndex,@Param("pageSize") Integer pageSize); }

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"><!--多條件直接查詢Param注解版--><select id="findByManyConditionByParam" resultType="user">select * from user where username like "%"#{username}"%" and sex=#{sex}limit #{startIndex},#{pageSize}</select> </mapper>

3.TestCrud測試類

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;/*** @author ：lijunxuan* @date ：Created in 2019/7/12 10:16* @description ：* @version: 1.0*/ public class TestCrud {/*** Mybatis多條件直接查詢Param注解版* @throws IOException*/@Testpublic void findByManyConditionByParam() throws IOException {InputStream inputStream = Resources.getResourceAsStream("Mybatis-configuration.xml");SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);SqlSession sqlSession = sqlSessionFactory.openSession();//獲取某接口的動態(tài)代理對象（獲取某接口的一個實現(xiàn)類）UserMapper userMapper = sqlSession.getMapper(UserMapper.class);QueryValueObject queryValueObject = new QueryValueObject();List<User> userMapperByConditionByMap = userMapper.findByManyConditionByParam("a","男",0,7);for (User user1 : userMapperByConditionByMap) {System.out.println(user1);}sqlSession.close();} }
