Serializable 剔除某些不想保存的字段 transient

示例：

package cn.com.chinatelecom.mms.pojo;

import java.io.Serializable;

public class Person implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    
    private String name;
    
    private int age;
    
    private transient String password;

    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;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + ", password="
                + password + "]";
    }
}

public static void main(String[] args) throws Exception {
        Person person = new Person();
        person.setAge(11);
        person.setName("Xiaoming");
        person.setPassword("111111");
        
        System.out.println(person.toString());
        
        Person xiaoming = Base64.deFromBase64(Base64.se2base64(person), Person.class);
        System.out.println(xiaoming.toString());
    }

运行结果：

Person [name=Xiaoming, age=11, password=111111]
Person [name=Xiaoming, age=11, password=null]
