RESTEasy:找不到内容类型应用程序/json 类型的编写器 [英] RESTEasy: Could not find writer for content-type application/json type

问题描述

我有一个安静的服务(post)，它使用(application/json)和产生(application/json).此服务的单个参数是一个带注释的 java 对象.

I have a restful service (post) that consumes (application/json) and produces (application/json). The single param for this service is an annotated java object.

我正在使用 org.jboss.resteasy.client.ClientRequest 将请求发送到服务.但是，我在客户端和异常中收到此异常:

I am using org.jboss.resteasy.client.ClientRequest to send the request to the service. However, I am getting this exception in the client end and the exception:

找不到内容类型应用程序/json 类型的编写器.

could not find writer for content-type application/json type.

这是否意味着我缺少一些库 jar 或者我必须为 application/json 编写自己的编写器?

Does this mean that I am missing some library jars or I have to write my own writer for application/json?

我使用的是resteasy 2.3.3.Final

I am using resteasy 2.3.3.Final

以下是我添加到我的 pom 中的各种我认为可能相关的依赖项:

Here are various dependencies I added to my pom that I think are probably related:

        <artifactId>jackson-mapper-asl</artifactId>
        <version>1.3.0</version>

推荐答案

<dependency>
      <groupId>org.codehaus.jackson</groupId>
      <artifactId>jackson-mapper-asl</artifactId>
      <version>${jackson-mapper-asl.version}</version>
      <scope>runtime</scope>
   </dependency>

   <dependency>
      <groupId>javax.xml.bind</groupId>
      <artifactId>jaxb-api</artifactId>
      <version>${jaxb-api.version}</version>
      <scope>runtime</scope>
   </dependency>

这就够了.
