Caused by: java.lang.IllegalStateException: Method has too many Body parameters: public abstract com.wxl.pros.test.web.common.CommonResObject com.wxl.pros.test.web.feign.OrderFeignClient.createOrder(com.wxl.pros.test.services.form.order.CreateOrderForm,com.wxl.pros.test.services.vo.User)

Here is one of my interface methods: 

@RequestMapping(value="/order/createOrder",method=RequestMethod.POST)
    public CommonResObject createOrder(@RequestBody OrderForm orderForm,@RequestBody User user);

If you have multiple arguments with one request body and more params. Specify the argument types using exact annotations:

ResponseMessage<String> getCustomInformation((@RequestBody CustomRequest request, @RequestParam("language") String language,
            @RequestParam("channel") String channel, @RequestParam("requestId") String requestId
