java 创建一个新对象并调用一个方法spring配置

Create a new object and call a method spring configuration

提问by sravanreddy001

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

是否有一种捷径可以在 Spring xml 配置文件中实现以下功能。

new MyObject().getData()

instead of

代替

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

I know how to do it in 2nd case.

我知道如何在第二种情况下做到这一点。

<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.

我确信必须有一种方法可以在单个定义中做到这一点。请建议。

Have you considered using an anonymous bean in your MethodInvokingFactoryBean?

你有没有考虑在你的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 MyObjectinstance will be in your ApplicationContext, though, so if you need it there, you may want to look into that.

这基本上等同于您所拥有的，除了没有中间 bean 定义这一事实。不过，我不确定该MyObject实例是否会在您的ApplicationContext.

You could try with @Autowire.

你可以试试用@Autowire.

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

在需要MyObjectbean的类中，您可以使用以下内容：

public class MyClass {

      @Autowire
      MyObject myObject;

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

}

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