transient java关键字

transient 这个关键字虽然不常用，但对于一些比较保密的字段起到保护作用，比如密码、银行卡等

package com.xj.nutz.bean;import org.nutz.dao.entity.annotation.Id;import org.nutz.dao.entity.annotation.Table;@Table(value = "tb_user")public class User {@Idprivate long id;private String name;private transient String password;public long getId() {return id;}public void setId(long id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

在调用toString方法时密码就不会被显示
