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 ????@JsonIgnore16 ????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返回JSON到前台的对象属性设置
