@PostConstruct&检查异常 [英] @PostConstruct & Checked exceptions

问题描述

在 @PostConstruct 文档中，它说注释方法：

In the @PostConstruct doc it says about the annotated methods:

该方法不得抛出被检查的异常。

如何处理例如一个IOException可以抛出这样的方法？只需将它包装在RuntimeException中，让用户担心对象的初始状态有问题？
或者是@PostConstruct错误的地方来验证和初始化注册的依赖关系的对象？

How would one deal with e.g. an IOException which can be thrown in such a method? Just wrap it in a RuntimeException and let the user worry about the faulty initial state of the object? Or is @PostConstruct the wrong place to validate and initialize objects which got their dependencies injected?

推荐答案

是的，它在运行时异常中。预先说明一些更具体的东西，如 IllegalStateException 。

Yes, wrap it in a runtime exception. Preferebly something more concrete like IllegalStateException.

请注意，如果init方法失败，通常应用程序将不会启动。

Note that if the init method fails, normally the application won't start.
