mybatisplus使用xml的示例详解

mybatis-plus:
mapper-locations: classpath:mapper/*.xml

public interface UserMapper extends BaseMapper {
List findAll();

List<User> selectByXml(@Param("name") String name);
}

<select id="selectByXml" resultType="com.example.mybatisplusdemo.sample.model.User">
    select *
    from user
    <where>
        <if test="name != null and name != ''">
            and name = #{name}
        </if>
    </where>
</select>

@Test
void test7(){
List users = userMapper.selectByXml("Jone");
users.stream().forEach(System.out::println);
}

public interface UserMapper extends BaseMapper {
List findAll();

// List selectByXml(@Param("name") String name);

List<User> selectByXml(@Param("ew") Wrapper<User> queryWrapper);
}

<select id="selectByXml" resultType="com.example.mybatisplusdemo.sample.model.User">
    select *
    from user
     ${ew.customSqlSegment}
</select>

@Test
void test7(){
    List<User> users = userMapper.selectByXml(new QueryWrapper<User>().eq("name","Jone"));
    users.stream().forEach(System.out::println);
}
