Which one is loading first? static block or spring bean?

Question

I run the object using spring and I call the method using the same object that was automatically added. This throws a NullPointerException. The problem is that I am calling a method inside a static block. Below is my code -

@Autowired
static MyPropertyManagerClass myPropertyManagerClass;

private static URL SERVICE_URL = null;

static {
    try {

        SERVICE_URL = myPropertyManagerClass.getServiceURL();
    }
    catch (Exception e) {
        log.error("Exception Occurred While Invoking myPropertyManagerClass.getServiceURL() : " , e);
    }
}

If I'm not mistaken, this is because the static block is loaded first. Is there any way I can do this work without creating an object with a new keyword?

Answer 1

static blocks are called when the class is initialized after loading it. The dependencies of your component are not yet initialized. This is why you get NullPointerException(your dependencies are zero).

, @PostConstruct. , .

Answer 2

static spring. @TheLostMind, " @PostConstruct ". new, spring factory-method Xml.

Answer 3

Static will be the first. Spring beans will be initialized after initialization of the BeanPostProcessor level.
