java - Spring MVC 可以反序列化 JSON(可以是对象或数组)吗？

Question

我有 Controller 在请求正文中接收 JSON，它可以是对象或对象数组。例如:

{
  "id" : 1,
  "name" : "Nick",
  "surname" : "Cave"
}

和

[
 {
   "id" : 1,
   "name" : "Nick",
   "surname" : "Cave"
 },
 {
   "id" : 2,
   "name" : "Jack",
   "surname" : "White"
 }
]

有没有办法强制 Spring 以与单独对象类似的方式将 JSON 反序列化为对象？

@RequestMapping(value = "/", method = RequestMethod.POST)
public void postController(@RequestBody User user, ...) {
   ...
}

如果不是，解析和验证此类消息的优雅方法是什么？

Answer 1

所以1)添加到maven:

<dependency>
  <groupId>org.codehaus.jackson</groupId>
  <artifactId>jackson-mapper-asl</artifactId>
  <version>1.9.13</version>
</dependency>

2)

@RequestMapping(value = "/addPerson",
                method = RequestMethod.POST,
                headers = {"Content-type=application/json"})
@ResponseBody
public JsonResponse addPerson(@RequestBody Person person) {
  logger.debug(person.toString());
  return new JsonResponse("OK","");
}
