Spring @RequestBody批注在Websphere Application Server上不起作用

我正在尝试在我的一个控制器方法中使用@RequestBody注释：

@Auditable(application = AuditApplication.DEP_TRXN, actionCategory = AuditActionCategory.READ_RESPONSE, actionDetail = "Viewed a tracking group.", event = AuditEventType.ACTION)
@RequestMapping(value = "groupView", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody
String ajaxGroupView(@RequestBody String payload, final HttpServletRequest request) throws TrackingServiceException, JsonGenerationException, JsonMappingException,
        IOException
{

    String requestBody = java.net.URLDecoder.decode(payload, "UTF-8");
    return requestBody;
}

当我在Jetty服务器上运行此代码时，我的“有效负载”获取post数据，但当我在WebSphereApplicationServer-8上运行相同的代码时，有效负载为“null”。我已启用mvc注释驱动。如何使此代码在WebSphereApplicationServer上工作

谢谢

你解决了这个问题吗？如果是，请告诉我你做了什么：-(
