spring mvc返回map的情况回顾
印象中平时在springmvc中比较少返回map的json数据，有点忘记了返回map时的json数据格式是怎样的，写这篇文章回顾一下，以便如果遇到返回map的json数据时能快速识别
返回List<Map<String ,User>>
@GetMapping("list")
public List<Map<String ,User>> dmeo2(){
List<Map<String,User>> list =new ArrayList<>();
Map<String, User> map = new HashMap();
User user = new User();
user.setUserName("zhangsan");
User user1 = new User();
user1.setUserName("beijing");
map.put("name", user);
map.put("address", user1);
list.add(map);
return list;
}
}public class User implements Serializable {
private static final long serialVersionUID = 7398333692719311866L;
private String userName;
public User(){
}
public User(String str){
this.userName = str;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}json数据格式样式
[{"address":{"userName":"beijing"},"name":{"userName":"zhangsan"}}]返回map数据
@GetMapping("map")
public Map<String ,User> dmeo1(){
Map<String, User> map = new HashMap();
User user = new User();
user.setUserName("zhangsan");
User user1 = new User();
user1.setUserName("beijing");
map.put("name" ,user);
map.put("address" ,user1);
return map;
}
public class User implements Serializable {
private static final long serialVersionUID = 7398333692719311866L;
private String userName;
public User(){
}
public User(String str){
this.userName = str;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}{"address":{"userName":"beijing"},"name":{"userName":"zhangsan"}}本文参与 腾讯云自媒体同步曝光计划，分享自作者个人站点/博客。
