Create a new object and call a method spring configuration

Question

Is there a short cut way to implement the following functionality in Spring xml configuration file.

new MyObject().getData()

instead of

Object obj = new MyObject();
obj.getData();

I know how to do it in 2nd case.

<bean id="obj" class="MyObject" />

<bean id="data" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
      <property name="targetObject"><ref local="obj" /></property>
      <property name="targetMethod"><value>getData</value></property>
 </bean>

I am sure there must be a way to do this in a single definition. Please suggest.

Answer 1

Have you considered using an anonymous bean in your MethodInvokingFactoryBean?

<bean id="data" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject"><bean class="MyObject" /></property>
    <property name="targetMethod"><value>getData</value></property>
</bean>

This is basically equivalent to what you have, except for the fact that there is no intermediate bean definition. I am not sure whether or not the MyObject instance will be in your ApplicationContext, though, so if you need it there, you may want to look into that.

Answer 2

You could try with @Autowire.

In the classes where you need the MyObject bean, you could use something like this:

public class MyClass {

      @Autowire
      MyObject myObject;

      public void myMethodofMyClass(){
         myObject.oneMethodOfMyObject();
      }

}

You can find more info in the spring reference manual (page 54).
