返回JSON到前台的对象属性设置

1、项目中使用JSON的第三方架包：jackson-annotations-2.8.0.jar

2、可以将对象的属性返回进行相应的处理 比如格式化时间、密码敏感等属性

如：User.java

package com.leecx.pojo;

import java.util.Date;

import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonInclude.Include;

public class User {
    
    private String name;
    private Integer age;
    
    @JsonIgnore
    private String password;
    
    @JsonFormat(pattern="yyyy-MM-dd hh:mm:ss a",locale="zh",timezone="GMT+8")
    private Date birthday;
    
    @JsonInclude(Include.NON_NULL)
    private String desc;
    
    
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public Date getBirthday() {
        return birthday;
    }
    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }
    public String getDesc() {
        return desc;
    }
    public void setDesc(String desc) {
        this.desc = desc;
    }
    
    
    
    
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    

}

其中：@JsonFormat(pattern="yyyy-MM-dd hh:mm:ss a",locale="zh",timezone="GMT+8")  可以对时间进行格式化设置

@JsonIgnore  可以对敏感数据进行保护

@JsonInclude(Include.NON_NULL)   可以对要求返回的属性为NULL的不进行返回，如果有数据就正常返回等设置

经过上述设置 那么前台得到的JSON串如下：

{"status":200,"msg":"OK","data":{"name":"duanml","age":18,"birthday":"2018-04-10 06:47:58 下午","desc":"Hello Word!"},"ok":null}

上述中的password 属性值由于设置了保护措施，那么前台返回的时候就默认隐藏了
