本文介绍了在服务器上运行时，Java RESTful客户端无法调用api的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个在Java 14 Spring Boot微服务上运行的RESTful服务.我从运行在Java 7应用程序上的客户端调用它.

I have a RESTful service running on a Java 14 Spring Boot microservice. I call this from a Client running on a Java 7 Application.

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

我有一个调用api的RESful客户端.当我从测试main方法调用它时，它可以成功运行，并且得到了预期的结果，并且在客户端和服务器上都没有错误.

I have a RESful Client that calls the api. When I call it from a test main method, it works successfully, and I get the expected results and no errors on client and server.

问题

当我在JBoss中启动Java 7(Struts)应用程序并通过相同的RESTful客户端调用api时，会出现错误.

When I start the Java 7 (Struts) app in JBoss, and call the api via the same RESTful client, I get errors.

在Java 14服务器上:

我认为问题在于，当Struts Java 7客户端在JBoss中运行时，类路径与主路径不同.

I think the issue is because the classpath is different when the Struts Java 7 Client is running in JBoss as opposed from the main.

问题

在JBoss中运行时，如何解决此问题并成功调用api?

How can I fix this and call the api successfully when running in JBoss?

我尝试将以下依赖项添加到客户端和服务器，这没有区别.

I have tried adding the following dependencies to the client and server, it makes not difference.

    <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->

我发现了问题所在，但不确定如何解决.

I found what the problem is, but I am not sure how to fix it.

当我执行以下操作时:

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

在运行JBoss时使用approvalRequest时，有一个将对象转换为JSON的异常.

With the approvalRequest when I run JBoss, there's an exception converting the object to JSON.

推荐答案

我通过不使用json而是使用xml作为有效载荷来解决了这个问题:

I solved this by not using json, but rather xml as the payload:

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);

        ApprovalResponse approvalResponse = cr.post(xmlString, ApprovalResponse.class);

        System.out.println(approvalResponse.getApprovalId());

        return approvalResponse;
    } catch (Exception e) {
        e.printStackTrace();
    }

服务器

@PostMapping(value = "/rest/approvals-submit", consumes=MediaType.APPLICATION_JSON_VALUE, produces={MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE})
public @ResponseBody ResponseEntity<ApprovalResponse> submit(@RequestHeader(name="Authorization") String token, @RequestBody String approvalRequestXML) {
    System.out.println("ApprovalSubmitResource: "+approvalRequestXML);
    XStream xstream = new XStream();
    xstream.allowTypesByWildcard(new String[] {
            "com.nexct.approvalservice.**"
    });
    xstream.alias("approvalRequest", ApprovalRequest.class);
    ApprovalRequest approvalRequest = (ApprovalRequest) xstream.fromXML(approvalRequestXML);

    System.out.println("ApprovalSubmitResource approvalRequest: "+approvalRequest);
    System.out.println("ApprovalSubmitResource: "+approvalRequest.getMessageToEvaluator());
    //ApprovalResponse approvalResponse = approvalSubmitService.submit(approvalRequest);
    ApprovalResponse approvalResponse = new ApprovalResponse();
    System.out.println("ApprovalSubmitResource: "+approvalResponse);
    approvalResponse.setApprovalId("test id from server");
    return ResponseEntity.ok(approvalResponse);
}
