SpringBoot中前臺界面帶參數請求WebSocket請求報錯MethodArgumentNotValidException

ERROR 15708 --- [nboundChannel-4] .WebSocketAnnotationMethodMessageHandler : Unhandled exception from message handler method.

org.springframework.messaging.handler.annotation.support.MethodArgumentNotValidException: Could not resolve method parameter at index 0 in public void com.XX.energymanagement.controller.ElectorDevsDataController.getDevsData(java.lang.String,org.springframework.messaging.simp.SimpMessageHeaderAccessor): 1 error(s): [Error in object 'reqValue': codes []; arguments []; default message [Payload value must not be empty]]

前臺html代碼：

stompClient.send("/app/getDevsData", {}, value);
stompClient.subscribe('/topic/devsData', function (data) {
     console.log("name --"+data.body);
 });

後臺java代碼：

//reqValue-前臺傳入的參數
//headerAccessor 獲取前臺的SessionId
@MessageMapping("/getDevsData")
public void getDevsData1(String reqValue, SimpMessageHeaderAccessor headerAccessor){
    //省略業務邏輯
    messagingTemplate.convertAndSend("/topic/devsData", resultJson.toString());
}

錯誤原因：

參數reqValue="" （reqValue=" "不會報錯）或者reqValue=null;

檢查前臺代碼中value值
