@PostConstruct & Checked exceptions

Question

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

\"The method MUST NOT throw a checked exception.\"

How would one deal with e.g. an I

Answer 1

Generally, if you want or expect application start-up failure when one of your beans throws an exception you can use Lombok's @SneakyThrows.

It is incredibly useful and succinct when used correctly:

@SneakyThrows
@PostConstruct
public void init() {
    // I usually throw a checked exception
}

There's a recent write-up discussing its pros and cons here: Prefer Lombok’s @SneakyThrows to rethrowing checked exceptions as RuntimeExceptions

Enjoy!
