我需要创建一个消费JSON数据的Web服务，我尝试了一些示例代码，并能够在他们的项目结构中创建它们并使用它。

但是，当我尝试在我的项目结构中创建相同的服务并请求Web服务时，它会响应HTTP状态415 - 不支持的媒体类型

我已经将示例项目中的所有jar复制到了我现有的项目中，但我无法弄清楚问题可能出在哪里

以下是样本项目中使用的罐子

activation-1.1.jar

asm-3.1.jar

` package com.mindcraft.social;

public class SummaryData {

public SummaryData() {

super();

// TODO Auto-generated constructor stub

}

String summary;

public String getSummary() {

return summary;

}

public void setSummary(String summary) {

this.summary = summary;

}

@Override

public String toString() {

return "SummaryData [summary=" + summary + "]";

}

}

`

以下是我的网络服务代码

@POST

@Path("/personality")

@Consumes(MediaType.APPLICATION_JSON)

public Response createPersonality(SummaryData summaryData)

{

String data=summaryData.getSummary();

return Response.status(200).entity(data).build();

}

以下是请求代码

OkHttpClient client = new OkHttpClient();

MediaType mediaType = MediaType.parse("application/json");

RequestBody body = RequestBody.create(mediaType, "{\n\t\"summary\":\"this is

a text\"\n}");

Request request = new Request.Builder()

.url("http://localhost:8080/SocialNetwork/rest/linkedin/personality")

.post(body)

.addHeader("content-type", "application/json")

.addHeader("cache-control", "no-cache")

.addHeader("postman-token", "3540654e-c773-952e-ffd9-f92b85ca6010")

.build();

Response response = client.newCall(request).execute();`下面是答案
