@PostConstrution被多次调用

Question

I have created a class which implements two interfaces.

I have used a init method with @postconstruction annotation

I am observing that though bean is initialised only during start up, init method is called multiple times.

Answer 1

The @PostConstruct method will be called every time the bean is instantiated. This means either every time you do a "new", or, if you've registered your class with a @Service, @Repository, or any other anotation of sorts that registers the class as a spring bean, the first time you @Autowired it.

Watch out for instantations of the class aside from those if you are using another framework annotations like @ManagedBean in JSF, which could be instantiating your class without you realising it.
