有两种用法，一种是直接吧方法的返回值注入到实例的属性，二是用返回值定义成Bean

定义实体：

 

package  Bean.superIOCmethod;

 public   class  Person  {
   private Son son;
   private String age;
public String getAge() {
    return age;
}
public void setAge(String age) {
    this.age = age;
}
public Son getSon() {
    return son;
}
public void setSon(Son son) {
    this.son = son;
}
}


package  Bean.superIOCmethod;

 public   class  Son  {
  private String age;

public String getAge() {
    return age;
}

public void setAge(String age) {
    this.age = age;
}
}
 
package Bean.superIOCmethod;
public class Field {
   public static final String TEST_FIELD="welcom";
   public String getValue(){
    return "test";
   }
   public static String getStaticValue(){
    return "static test";
   }
}


配置文件：

 

<? xml version="1.0" encoding="UTF-8" ?>
<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >

< beans >
   <!--  非静态方法，使用targetObject  -->
   < bean  id ="son"  class ="Bean.superIOCmethod.Son" >
      < property  name ="age" >
        < bean  class ="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
           < property  name ="targetObject" >
               < ref  local ="value" />
           </ property >
           < property  name ="targetMethod" >
              < value > getValue </ value >
           </ property >
        </ bean >
      </ property >
   </ bean >
    <!--  静态方法，无需使用targetObject，但要配置targetClass  -->
   < bean  id ="staticson"  class ="Bean.superIOCmethod.Son" >
      < property  name ="age" >
        < bean  class ="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
           < property  name ="targetClass" >
             < value > Bean.superIOCmethod.Field </ value >
           </ property >
           < property  name ="targetMethod" >
              < value > getStaticValue </ value >
           </ property >
        </ bean >
      </ property >
   </ bean >
  
   <!--  将方法返回值定义成Bean  -->
   < bean  id ="sysProps"  class ="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
        < property  name ="targetClass" >
          < value > java.lang.System </ value >
        </ property >
        < property  name ="targetMethod" >
          < value > getProperties </ value >
        </ property >
    </ bean >
   
    < bean  id ="javaversion"  class ="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
       < property  name ="targetObject" >
         < ref  local ="sysProps" />
       </ property >
       < property  name ="targetMethod" >
         < value > getProperty </ value >
       </ property >
       < property  name ="arguments" >  
          < list >
            < value > java.version </ value >
          </ list >
       </ property >
    </ bean >
   < bean  id ="value"  class ="Bean.superIOCmethod.Field" >
   </ bean >
</ beans >

测试代码： 

public   static   void  main(String[] args)  throws  Exception  {
        
        String path=new Test().getClass().getResource("/").getPath();
        String realpath=path.substring(1, path.length());
        ApplicationContext context=new FileSystemXmlApplicationContext(realpath+"/superIOCmethod.xml");
        Son son1=(Son)context.getBean("son");
        Son son2=(Son)context.getBean("staticson");
        
        
        System.out.println("person age is:"+son1.getAge());
        System.out.println("person age is:"+son2.getAge());
        System.out.println(context.getBean("sysProps"));
        System.out.println(context.getBean("javaversion"));
 }

 

 

person age is:test
person age is:static test
