页面报Required String parameter ‘loanOrderNbr’ is not present解决办法

问题描述:

前面代码(angularjs)

var loanOrderNumber = $routeParams.loanOrderNumber;
    $scope.saveButton = true;
    $http.get("/test/business/order/viewDetail",{
        params : {
        ‘loanOrderNbr‘ : loanOrderNbr
        }
    }).success(function(request,status){        
        //
    }).error(function (data, status) {
        //
    });

后台代码(spring mvc)

//查看数据
    @RequestMapping(value = "/viewDetail")
    @ResponseBody
    public AtResponse detail(@RequestParam(name = "loadOrderNbr", required = true) String loadOrderNbr) {
        Map<String, Object> params = new HashMap<String, Object>();
        AtResponse<TxnAcct> resp = new AtResponse(System.currentTimeMillis());
        //.....
        return resp;
    }

当时以为是前面angularjs代码写得有问题,然而仔细对比其他功能的写法,发现没有什么区别,只是传的参数不一样而矣,非常迷惑,不解。后台也不报错(没有输出spring日志),然后将请求链接直接在浏览器中访问: 
http://localhost:9770/test/business/order/viewDetail?loanOrderNbr=201706091042631

页面提示如下错误信息: 
Required String parameter ‘loanOrderNbr’ is not present

发现是前端传的参数名与后端代码定义的参数名不一致导致的,囧:

前端参数是:loanOrderNbr

后端参数是:loadOrderNbr

另:网上有另一解决方法参考

将后台代码修改为:

@RequestMapping(value = "/viewDetail")      
@ResponseBody      
public ResponseBase addQuestion(@RequestBody Map<String,Object> params){
      String loanOrderNbr = params.get("loanOrderNbr").toString();
}
