Question

我有一个简单的Object，它包含一个String和一个Map<String, Object>定义如下：

我的对象

@XmlRootElement
public class WebServicePatternObject {

    private @Getter @Setter String code;
    private @Getter @Setter Map<String, Object> fieldsMap = new HashMap<>();

    public WebServicePatternObject() {
    }

    public WebServicePatternObject(String code, Map<String, Object> fieldsMap) {
        this.code = code;
        this.fieldsMap = fieldsMap;
    }
}

客户端

public String getResult(String paramValues, Map<String, Object> mapFieldsValues) 
         throws Exception {
    try {
        Client client = Client.create();

        String uriTarget = 
                   "http://10.6.6.6:8080/admin/ressources-ws-rest/patterns/lastSequence";
        WebServicePatternObject wspo = 
                                new WebServicePatternObject(paramValues, mapFieldsValues);
        WebResource webResource = client.resource(uriTarget);

        //{"code":"CODE_PA","fieldsMap":{"code_1":123456,"code_2":"abcd"}}
        System.out.println(new ObjectMapper().writeValueAsString(wspo));

        ClientResponse response = webResource.type(MediaType.APPLICATION_JSON)
                .post(ClientResponse.class, new ObjectMapper().writeValueAsString(wspo));

        if (response.getStatus() != 201) {
            throw new Exception("Exception Occured - HTTP Error Code :" 
                                 + response.getStatus());
        }

        String output = response.getEntity(String.class);
        //This return SUCCESS_RESULT
        System.out.println(output);
        return output;
    } catch (Exception ex) {
        throw new Exception("Something wrong!");
    }
}

服务方

@Path("/patterns")
public class PatternsWebService {

    @POST
    @Path("/lastSequence")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response getLastSequence(WebServicePatternObject wspo) {
        //WebServicePatternObject{code=CODE_PA, fieldsMapAP={}} <<----------Empty Map, Why?
        System.out.println(wspo);
        return Response.status(201)
                .entity("SUCCESS_RESULT")
                .build();
    }
}

当我用：{/ p>打电话给getResult(String paramValues, Map<String, Object> mapFieldsValues)时

Map<String, Object> map = new HashMap<>();
map.put("code_1", 123456);
map.put("code_2", "abcd");
getResult("CODE_PA", map);

服务响应为SUCCESS_RESULT，但服务中的地图为空fieldsMapAP={}

我的问题是，为什么String发送成功但是Map是空的，我想我的代码中遗漏了一些东西，有什么想法吗？
