Invoke static method from spring config

Question

Is it possible to invoke static method in Spring configuration file?

public MyClass {

   public static void staticMethod() {
       //do something
   }

}

<bean id="myBean" class="MyClass">
   <!-- invoke here -->
</bean>

Answer 1

1. When the static method creates an instance of MyClass you an do it like this

config

<bean id="myBean" class="MyClass" factory-method="staticMethod">
   <!-- invoke here -->
</bean>

code

public static MyClass staticMethod() {
       //create and Configure a new Instance
}

2. If you want the method only to be called on bean instantiation spring can't do it this way.

config

<bean id="myBean" class="MyClass" init-method="init">
   <!-- invoke here -->
</bean>

code

public static void staticMethod() {
       //create and Configure a new Instance
}

public void init() {
     staticMethod();
}

Answer 2

try this

<bean id="b1" class="org.springframework.beans.factory.config.MethodInvokingBean">
    <property name="staticMethod" value="MyClass.staticMethod" />
</bean>
