Java RESTful 客户端在服务器上运行时无法调用 api。

Question

我有一个RESTful服务在Java14SpringBoot微服务上运行。我从运行在Java 7应用程序上的客户机调用这个。

+----------------------+          +-------------------------------+
|  Java 7 REST Client  |  ---->   |  Java 14 Spring Boot Service  |
+----------------------+          +-------------------------------+

我有一个调用api的RESful客户端。当我从testmain方法调用它时，它成功工作，我得到了预期的结果，客户端和服务器上没有错误。

问题

当我在JBoss中启动Java7（Struts）应用程序，并通过同一个RESTful客户端调用api时，我收到了错误。

在 Java 14 服务器上：

我认为这个问题是因为当Struts Java 7客户机在JBoss中运行时，类路径与主类路径是不同的。

问题

在 JBoss 中运行时，如何解决此问题并成功调用 api？

我尝试将以下依赖项添加到客户端和服务器，这没有区别。

Java 7 REST客户端:

    //System.out.println(endpointUrl);
    try {
        ClientResource cr = new ClientResource(endpointUrl);
        ChallengeResponse challengeResponse = new ChallengeResponse(ChallengeScheme.HTTP_OAUTH_BEARER);
        challengeResponse.setRawValue(token);
        cr.setChallengeResponse(challengeResponse);

        Request req = cr.getRequest();
        Series<Header> headerValue = new Series<>(Header.class);
        req.getAttributes().put(HeaderConstants.ATTRIBUTE_HEADERS, headerValue);

        Representation representation = cr.post(approvalRequest);
        String json = representation.getText();
        //System.out.println(json);

        // now convert the response to java
        ObjectMapper objectMapper = new ObjectMapper();
        ApprovalResponse approvalResponse = objectMapper.readValue(json, ApprovalResponse.class);
        //System.out.println(approvalResponse);
        System.out.println(approvalResponse.getApprovalId());

        return approvalResponse;
    } catch (Exception e) {

它在这一行失败：

我发现了问题所在，但我不确定如何解决它。

当我执行以下操作时:

        Gson gson = new Gson();
        String approvalRequestJsonStr = gson.toJson(approvalRequest);

当我运行JBoss时，使用批准请求，将对象转换为JSON时出现异常。

Answer 1

我通过不使用json而是使用xml作为有效负载来解决这个问题：

客户

    try {
        ClientResource cr = new ClientResource(endpointUrl);
        ChallengeResponse challengeResponse = new ChallengeResponse(ChallengeScheme.HTTP_OAUTH_BEARER);
        challengeResponse.setRawValue(token);
        cr.setChallengeResponse(challengeResponse);

        Request req = cr.getRequest();
        Series<Header> headerValue = new Series<>(Header.class);
        req.getAttributes().put(HeaderConstants.ATTRIBUTE_HEADERS, headerValue);

        XStream xstream = new XStream();
        xstream.alias("approvalRequest", ApprovalRequest.class);
        String xmlString = xstream.toXML(approvalRequest);
