使用Jersey和Jackson消费JSON请求

我正在开发一个基本的Jersey WebService，它将接受JSON请求并以JSON发回数据。我还开发了一个基本的测试客户端来发送请求并作为Java Standalone程序获得响应。我能够成功地发送和获取GET和POST请求（text/html）的响应，但是当我发送JSON数据时，我得到的错误是低于。这似乎与杰克逊翻译有关。我不使用maven。使用Jersey和Jackson消费JSON请求

import com.xxx.inventory.bean.XXXRequestBean; 

@Path("UserInfoService") 
public class XXXXService { 


@GET 
@Path("/name/{i}") 
@Produces(MediaType.TEXT_XML) 
public String userName(@PathParam("i") String i) { 

    System.out.println(" ********************* Web Service Request GET ************************* "); 
    String name = i; 
    return "<User>" + "<Name>" + name + "</Name>" + "</User>";

我想通在列出jar之后，将jackson-jaxrs-json-provider-2.2.0.jar更改为2.4.1修复了这个问题。也注意到在toString方法中的JSON构造中的其他一些错误，在几个地方的字段名称是错误的。 – Dexter

我也面临同样的问题..更新最新版本的jaxson-jaxrs-base和jackson-jaxrs.json-provider后解决了这个问题..谢谢。 – user2376546

林罐子的名单我想它上市的罐子后，改变杰克逊JAXRS JSON的提供商 - 2.2.0.jar到2.4.1解决了该问题。

也注意到toString方法中的JSON构造中的其他一些错误，在几个地方的字段名称是错误的。

遇到相同的问题，在我的情况下，它通过帮助pom.xml中的Maven的依赖关系管理系统中添加的实现作为依赖于客户端修复java.lang.AbstractMethodError：

      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-core</artifactId> 
      <version>2.2.2</version>

     <dependency> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-databind</artifactId> 
      <version>2.2.2</version>
