Spring Bean包装类案例之自定义PropertyEditor

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:

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:
