为什么编写媒体类型应用程序/ json失踪 [英] Why writer for media type application/json missing

问题描述

基本上我有一个宁静的服务（post）消耗（ application / json ）并生成（ application / json ）。此服务的单个参数是带注释的java对象。

Basically 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 将请求发送给服务。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 application / json 类型。

这是否意味着我缺少一些库jar或我必须为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?

我正在使用resteasy 1.1

I am using resteasy 1.1

推荐答案

拉曼是对的。 Jettison是一个有效的选择。你也可以使用杰克逊。
如果您使用maven，就像在pom中包含以下依赖项一样简单：

Raman is correct. Jettison is a valid option. You can also use Jackson. If you are using maven, it is as simple as including the following dependency in you pom:

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson-provider</artifactId>
        <version>2.3.2.Final</version>
    </dependency>

此时编写代码应该没有问题，例如：

At which point you should have no problem writing code such as:

    SomeBean query = new SomeBean("args")
    request.body("application/json", query);
    ClientResponse response = request.post();
