Java 它不会捕获存储过程Spring Boot的错误

我有一个raiserror程序，spring没有发现我的错误，或者可能我做错了什么。我留下密码

我还希望它位于括号和键[{Cod:3，Name:“ccc”，Email:ccc@hotmail.com“}]诸如此类。

因为存储过程的整个过程都已成功执行，所以不会抛出任何异常，因此无法捕获任何内容。只有当过程本身未能执行时，才能引发异常-SQLException

因此，如果某些操作（如DQL或DML）无法执行，您应该在过程中返回一些内容。（常见的方法是返回错误代码）

更新
我不熟悉T-SQL，但我在MS官方网站上找到了一个示例，演示了我所说的在您的过程中返回状态代码的内容。它的概念就像HTTP请求和响应一样，我们总是首先使用状态代码来确定请求是否已成功处理。如果出现问题，我们将进一步检查响应中的错误消息

---

首先，我对Spring框架不太了解，但我可以在您的代码中看到一些问题。您可以在进程的

CATCH

块中捕获SQL异常，然后执行

PRINT

。这是“吞咽”的例外，它不会向外界提出。在纯ADO.NET中，通过为

InfoMessage

设置eventhandler，您实际上可以捕获

PRINT

消息，但再一次，我对Spring的了解还不够，无法说明您是否可以在那里执行。最好是在procs

CATCH

块中重新引发错误，这样您的服务就会捕获它。但是当我进行调试时，它不会捕获@service中的捕获。它实际上是经过的，好像我的程序中没有错误。如果我输入同一封电子邮件，它应该会生成一个错误，但它不会。当然，它不会捕获它，因为没有错误“冒泡”到您的服务。错误在SQL

CATCH

块中处理。是的，我已经更改了它。但我仍然无法获得错误，或者创建一个输出参数会更好吗？您能给我一个如何执行的示例吗？控制台向我显示了SQLEXCEPTIONHELPER“错误电子邮件”，但现在它向我显示：“org.hibernate.exception.sqlgrammareException:调用CallableStatement.getMoreResults时出错”。我并没有得到消息。
