@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:

该方法不得抛出已检查的异常."

人们将如何处理例如可以在这种方法中抛出的 IOException?只是将它包装在一个 RuntimeException 中，让用户担心对象的错误初始状态?或者@PostConstruct 是验证和初始化注入依赖项的对象的错误位置?

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，将其包装在运行时异常中.最好是更具体的东西，比如 IllegalStateException.

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

请注意，如果 init 方法失败，则应用程序通常不会启动.

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