Java生成xml文件

JavaBean:

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

 
}
