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
