Question

@Configurable
public TestClass(){

@Autowired SomeOtherClass otherClass;

public TestClass(Var1 var){

System.out.println(otherClass);

}


}

I using compile time weaving and call new testClass(var). i using dependency injection on the constructor like above “otherClass”. It printed out ‘null’. From my test, dependency injection ‘otherClass’ cannot be initialized in constructor. what should i do to allow dependency injection on “constructor” ?

Answer 1

In support of the answer by Ralph.

From the Spring Autowired documentation.

Fields are injected right after construction of a bean, before any config methods are invoked.
