SpringBoot MybatisPlus 执行原生Sql的三种方式

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. yml文件中添加MybatisPlus配置:

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

1. 使用SqlRunner.db()

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);
    
    }
