spring - Websphere 应用程序服务器 - Spring MVC - java.lang.NoSuchMethodError : org/codehaus/jackson/map/type/TypeFactory. 类型

Question

由于客户端限制，我正在使用 WAS 8.0 来部署 Spring MVC 应用程序。我有一些 Controller 定义了一个微型网络服务。

我尝试部署在一些常见的服务器上，它运行正常，但是当我尝试部署到 WAS 时，情况是这样的:

• 我可以使用 GET 服务，而不依赖于获取的元素。
• 我可以用 XML 呈现 GET 调用。
• 我可以使用 jackson 注释在 JSON 中呈现 GET 调用。

但是当我尝试使用一些 POST 调用时，应用程序抛出此错误(从 WAS JVM System Out 获取):

在 org.codehaus.jackson.mapper 库的最新版本中，错误引用的函数已被弃用。因此，我尝试从库的 1.0 版切换到 1.9.12 版，并在每次更改时清洁部署它(以避免类版本冲突)。

谷歌搜索后，我发现一个帖子说它一定是类加载器问题，所以我在 WAS 中选择 PARENT_LAST 配置。但什么也没发生。

我现在不明白里面发生了什么。日志中没有更多信息。

编辑>>> 我忘记附加与 HTTP 调用关联的 Controller 函数

@RequestMapping(method = RequestMethod.POST)
@ResponseBody
public Map<String, String> addIncidence(@RequestBody Incidence incidence) {
    incidenceService.addIncidence(incidence);

    Map<String, String> response = new HashMap<String, String>();

    response.put("token", incidence.getToken().toString());
    response.put("service_request_id",
            incidence.getServiceRequestIdString());
    response.put("service_notice", "some text from server");
    response.put("account_id", null);

    return response;
}

提前致谢。

WebSphere 8.0 随 Jackson 1.5(或 1.6)开箱即用(它被重新打包，您必须展开它以检查版本的 META-INF)。因此，如果您希望在 1.5(或 1.6)之后引入功能，则需要反转类加载顺序。正如 fnt 上面评论的那样，如果您要这样部署，请确保在 EAR 和 WAR 级别更改顺序。
