一、使用Spring的JdbcTemplate

@Autowired
private JdbcTemplate jdbcTemplate;

public void queryBySql(){
    List<Map<String, Object>> lstData = jdbcTemplate.queryForList("select * from t_test");
}

二、使用Mybatis-plus的SqlRunner

1.配置MybatisPlus:

mybatis-plus:
  global-config:
    enable-sql-runner: true

2.执行Sql语句

public void queryBySql(){
    List<Map<String, Object>> lstData = SqlRunner.db().selectList("select * from abc");
}

三、使用Mybatis-plus的Mapper

public interface CustomMapper extends BaseMapper<Entity> {

    @Select("SELECT * FROM your_table WHERE condition = #{value}")
    List<Entity> selectByCustomSql(@Param("value") String value);

    @Select("<script>" +
            "SELECT item_id,is_assign,shop_id FROM t_order_detail_items " +
            "where shop_id = #{shopId} and is_deleted = #{status}  " +
            "</script>")
    @Results({
            @Result(property = "itemId", column = "item_id"),
            @Result(property = "isAssign", column = "is_assign"),
            @Result(property = "shopId", column = "shop_id"),
    })
    List<ShopItemVO> selectBySql(@Param("shopId") Integer shopId, @Param("status") Short status);
}
