JAXRS客户端找不到邮件正文编写器 [英] JAXRS client can't find message body writer

问题描述

我有一个像这样配置的jaxrs客户端：

I have a jaxrs client configured like this:

<jaxrs:client id="opaRestProxy" name="opaRestProxy"
        address="${endpoint}" serviceClass="com.test.RestProxy"
        inheritHeaders="true" threadSafe="true">
        <jaxrs:headers>
            <entry key="Accept" value="application/json" />
            <entry key="Content-Type" value="application/json" />
        </jaxrs:headers>
    </jaxrs:client>

但是当我发送请求时，我得到以下异常：

But when I send a request I get the following exception:

Caused by: org.apache.cxf.interceptor.Fault: .No message body writer has been found for class : class com.test.RequestObject, ContentType : application/json.
    at org.apache.cxf.jaxrs.client.ClientProxyImpl$BodyWriter.handleMessage(ClientProxyImpl.java:646)
    at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:263)
    at org.apache.cxf.jaxrs.client.ClientProxyImpl.doChainedInvocation(ClientProxyImpl.java:527)
    ... 47 more

我的RestProxy类看起来像这样：

My RestProxy class looks like this:

@Component
public interface RestProxy {

  @POST
  @Path("/getSomething")
  String getSomething(RequestObject RequestObject);
}

推荐答案

如果您使用的是Jackson JSON库需要将这些xml标记添加到应用程序上下文中。

If you are using Jackson JSON library you need to add these xml tags to your application context.

<jaxrs:providers>
<bean id="jacksonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider" />
</jaxrs:providers>

如果您正在使用任何其他库，请将该bean添加到providers标记。希望有所帮助！

If you are using any other library add that bean to the providers tag. Hope that helps!
