【问题描述】：
我正在使用 jersey 客户端向 REST 服务器发送 POST 请求。我在请求和响应中都使用了 JAXB 对象。
public RegisterUserResponse apply(RegisterUserRequest input) {
logger.debug("sending user authentication request");
return webResource.
path(requestPath).
path(registerUserPath).
accept(MediaType.TEXT_HTML). // set response content type
type(MediaType.APPLICATION_XML). // set request content type
post(RegisterUserResponse.class, input);
}
这里两个RegisterUserRequest/Response 类都是xml 注释的。
我得到的响应是一个 text/html 响应，它是一个 xml 字符串，格式可以转换回 RegistrationResponse
我收到一条错误消息，提示缺少 RegistrationResponse 和 text/html 消息正文编写器。有什么办法可以解决这个问题。
我的异常堆栈跟踪如下
