将Map键，值对转换为@responseBody对象的JSON属性 [英] Convert Map key,value pairs into JSON properties of a @responseBody object

问题描述

我想知道这是否可以实现.我有一个简单的春季服务:

I am wondering if this can be achieved. I have a simple spring service :

public @ResponseBody ResponseObject getResults(
            HttpServletRequest request, HttpServletResponse response, @RequestBody RequestInput requestInput )

我的ResponseObject看起来像这样:

My ResponseObject looks like this :

public class ResponseObject {
    private String id;  
    private String value;
    private Map<String,String> keyValuePairs;
    .... and the regular getter/setters

当我向keyValuePairs添加一些值时.我收到这样的JSON响应:

When i add some values to keyValuePairs. I get a JSON response like this :

 {
        "id": "56LTY",
        "value": "56 Large Thank You",
        "keyValuePairs": {
          "origin": "Vietnam",
          "ship" : "Air"
        }
}

我想要这样的JSON响应:

I would like to have my JSON response like so :

 {
        "id": "56LTY",
        "value": "56 Large Thank You",
        "origin": "Vietnam",
        "ship" : "Air"
}

这可行吗?

推荐答案

尝试使用 com.fasterxml.jackson.annotation.JsonAnyGetter 批注:

@JsonAnyGetter
public Map<String, String> getKeyValuePairs() {
    return keyValuePairs;
}
