javabean:

 

package  Bean.CustomerPropertyEditor;

public   class  Company  ... {
    private Person director;

    public Person getDirector() ...{
        return director;
    }

    public void setDirector(Person director) ...{
        this.director = director;
    }
}


package  Bean.CustomerPropertyEditor;

public   class  Person  ... {
  private String name;
  private int age;
  public Person(String name,int age)...{
      this.name=name;
      this.age=age;
  }
public int getAge() ...{
    return age;
}
public void setAge(int age) ...{
    this.age = age;
}
public String getName() ...{
    return name;
}
public void setName(String name) ...{
    this.name = name;
}
}

 自定义PropertyEditor

 

package  Bean.CustomerPropertyEditor;

import  java.beans.PropertyEditorSupport;

public   class  PersonEditor  extends  PropertyEditorSupport  ... {

    @Override
    public void setAsText(String text) throws IllegalArgumentException ...{
        String[] temp=text.split("-");
        String name=temp[0];
        int age=Integer.parseInt(temp[1]);
        Person p=new Person(name,age);
        setValue(p);
    }

}

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 >

  < bean  id ="customEditorConfigure"  class ="org.springframework.beans.factory.config.CustomEditorConfigurer" >
    < property  name ="customEditors" >
       < map >
          <!--  确定目标类  -->
          < entry  key ="Bean.CustomerPropertyEditor.Person" >
            < bean  class ="Bean.CustomerPropertyEditor.PersonEditor" ></ bean >
          </ entry >
       </ map >
    </ property >
  </ bean >
  < bean  id ="company"  class ="Bean.CustomerPropertyEditor.Company" >
    < property  name ="director" >
       < value > gaoxiang-26 </ value >

测试代码：

 

package  Bean.CustomerPropertyEditor;

import  org.springframework.context.ApplicationContext;
import  org.springframework.context.support.FileSystemXmlApplicationContext;

import  Bean.FactoryMethods.Test;

public   class  test  ... {

    /** *//**
     * @param args
     */
    public static void main(String[] args) ...{
        String path=new Test().getClass().getResource("/").getPath();
        String realpath=path.substring(1, path.length());
        ApplicationContext context=new FileSystemXmlApplicationContext(realpath+"/propertyEditor.xml");
        Company c=(Company)context.getBean("company");
        System.out.println(c.getDirector().getName()+"*"+c.getDirector().getAge());
    }

}

 

运行结果：
