address="${endpoint}" serviceClass="com.test.RestProxy"

<jaxrs:headers>
<entry key="Accept" value="application/json" />
<entry key="Content-Type" value="application/json" />
</jaxrs:headers>
</jaxrs:client>
But when I send a request I get the following exception:
但是当我发送请求时，我收到以下异常：
Caused by: org.apache.cxf.interceptor.Fault: .No message body writer has been found for class : class com.test.RequestObject, ContentType : application/json.

If you are using Hymanson JSON library you need to add these xml tags to your application context.
如果您使用 Hymanson JSON 库，您需要将这些 xml 标签添加到您的应用程序上下文中。
<jaxrs:providers>
<bean id="HymansonProvider" class="org.codehaus.Hymanson.jaxrs.HymansonJsonProvider" />
</jaxrs:providers>
If you are using any other library add that bean to the providers tag. Hope that helps!
如果您正在使用任何其他库，请将该 bean 添加到 providers 标记中。希望有帮助！

If you are consuming using javax.ws.rs.client.Client, please register the provider using client.register(new HymansonJsonProvider());
如果您正在使用 using javax.ws.rs.client.Client，请使用注册提供程序client.register(new HymansonJsonProvider());

This answers point me in the right direction, yet i had to add on two parts to make it work on web.xml
这个答案为我指明了正确的方向，但我必须添加两部分才能使其在 web.xml 上工作
<init-param>
<param-name>jaxrs.providers</param-name>
<param-value>
org.codehaus.Hymanson.jaxrs.HymansonJaxbJsonProvider
(writeXsiType=false)
</param-value>
</init-param>
And on the client call:
在客户端调用中：
List<Object> providers = new ArrayList<>();
// add custom providers if any
providers.add(new HymansonJaxbJsonProvider());
WebClient client = WebClient.create(ENDPOINT_ADDRESS,providers);
