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 {

@Id
private 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
