Question

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。

我得到的是响应是一个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，指出RegistrationResponse和text / html消息正文编写器丢失了。什么可以解决这个问题。

我的异常堆栈跟踪如下

对于text/html媒体类型，JAX-RS / Jersey似乎默认不使用JAXB。您可以利用标准MessageBodyReader / MessageBodyWriter机制来插入您自己对利用JAXB的媒体类型的处理。

以下是我给出的答案的链接，其中包含示例MessageBodyReader：
