java如何向映射添加所有@PostMapping参数？

Question

我想提供一个POSTservlet，它接受以下JSON内容：

{
  "name": John
  "age": 25,
  "some": "more",
  "params: "should",
  "get": "mapped"
}

其中两个属性应该显式映射到定义的参数。所有其他参数都应该进入Map<String, String>

问题：如何让Spring将它们直接映射到bean的映射中

@RestController
public void MyServlet {
   @PostMapping
   public void post(@RequestBody PostBean bean) {

   }
}

public class PostBean {
   private String name;
   private String age;

   //all other json properties should go here
   private Map<String, String> map;
}

Answer 1

public class PostBean {
    private Map<String, String> map;

    @JsonAnyGetter
    public Map<String, String> getMap() {
        return map;
    }

    @JsonAnySetter
    public void setMap(String name, String value) {
        if (this.map == null) map = new HashMap<>();
        this.map.put(name, value);
    }
}
