Java如何使用Query动态拼接SQL详解

2021-07-02 14:29零落星尘 Java教程

这篇文章主要给大家介绍了关于Java如何使用Query动态拼接SQL的相关资料,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

前言

之前有做个一个自定义报表的查询,这里使用的是一个动态的sql拼接,是前端选择了什么指标就查询什么信息!(这里的指标是多个表的字段,前端随便选择了这些指标,然后后端根据这些指标拼接sql,返回这些指标的数据)。

}

这个repository要继承 extends jparepository<t, id> 才可以,写漏了。

上面使用了union 进行表之间的关联查询,关联的表有点多,所以代码有些长,同时因为表多,指标(表的属性)有500多个,无法确定查询的返回实体,所以只能自己根据数据的返回给数据绑定属性。
