在Weblogic 11g中尝试使用fastxml将json转换为POJO时，@ RequestBody获取空值

Question

我有一个代码，该代码从控制器调用中获取一些json并使用fastxml将其转换为Java对象。该代码在weblogic 12c中正常工作。但是，当我尝试在weblogic 11g中部署相同的代码时，创建的对象为null。

代码段：

@RequestMapping(value = "/getDetails",
        method=RequestMethod.POST, 
        produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ConsolidatedResponse> getDetails(@RequestBody       MyRequest request) {
    long t1 = System.currentTimeMillis();
    ResponseEntity<ConsolidatedResponse> response = null;
    ConsolidatedResponse respDetails;
    if(request!=null)
System.out.println("recieved "+request.toString());
    else
        System.out.println("recieved null");

此处请求在11g weblogic中变为空。
