Spring boot parse POST json example 2016-06-15 04:43
You can post a form to server and parse the data. Json is a lightweight data format, it's better to post json when your data is complex. In the page I will show you how to parse json data in Spring Boot. You can use Postman or other REST clients to send a POST request. I prefer to use REST Client in Intellij IDEA. Click Use Intellij IDEA REST Client POST json for more detail.

SimpleController
@RestController
@EnableAutoConfiguration
public class SimpleController {
@RequestMapping(value = "/get-json", method = RequestMethod.POST)
public String getJson(@RequestBody UserVo userVo) {
return userVo.toString();
}
public static void main(String[] args) {
SpringApplication.run(SimpleController.class, args);
}
}
UserVo
public class UserVo implements Serializable {
private static final long serialVersionUID = 3267101817151303146L;
private String name;
private int age;
//getter and setter method
@Override
public String toString() {
return "UserVo{" +
"name='" + name + '\'' +
", age=" + age +
'}';
}
}
Run SimpleController and post json to /get-json(Click Use Intellij IDEA REST Client POST json to learn how to post json) Spring will help you parse json to UserVo. But you need make sure the properties in vo class are same with json. If they are not match the properties in UserVo will be null.
