返回JSON到前台的对象属性设置

Posted 2020-10-30 ╱、隐风っ九剑

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

 1 package com.leecx.pojo;
 2 
 3 import java.util.Date;
 4 
 5 import com.fasterxml.jackson.annotation.JsonFormat;
 6 import com.fasterxml.jackson.annotation.JsonIgnore;
 7 import com.fasterxml.jackson.annotation.JsonInclude;
 8 import com.fasterxml.jackson.annotation.JsonInclude.Include;
 9 
10 public class User {
11     
12     private String name;
13     private Integer age;
14     
15     @JsonIgnore
16     private String password;
17     
18     @JsonFormat(pattern="yyyy-MM-dd hh:mm:ss a",locale="zh",timezone="GMT+8")
19     private Date birthday;
20     
21     @JsonInclude(Include.NON_NULL)
22     private String desc;
23     
24     
25     public String getPassword() {
26         return password;
27     }
28     public void setPassword(String password) {
29         this.password = password;
30     }
31     public Date getBirthday() {
32         return birthday;
33     }
34     public void setBirthday(Date birthday) {
35         this.birthday = birthday;
36     }
37     public String getDesc() {
38         return desc;
39     }
40     public void setDesc(String desc) {
41         this.desc = desc;
42     }
43     
44     
45     
46     
47     public String getName() {
48         return name;
49     }
50     public void setName(String name) {
51         this.name = name;
52     }
53     public Integer getAge() {
54         return age;
55     }
56     public void setAge(Integer age) {
57         this.age = age;
58     }
59     
60 
61 }

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
