第一种情况是传递单个值到后台：
js代码

$.ajax({
            url: $path + '/rbac/user/getDeptId',
            type: 'post',
            dataType: 'json',
            data: 'userId='+userId ,
            success:function(data){
            	
            	console.log(data);
            	
            	userCode=data.result.data.code;
            	deptId=data.result.data.deptId.id;
            	
            	if(data.result.data.deptId.id==20){
            	
            },error:function(data){
            	
            	alert("数据加载异常"+data.id);
            }
        })

controller代码

    @RequestMapping(value="getDeptId",method=RequestMethod.POST)
	@ResponseBody
	public Map<String, Object> getDeptId(HttpServletRequest request, HttpServletResponse response, Long userId ){
		
		    User user=userService.selDeptId(userId);
		    
		    Map<String, Object> modelMap = new HashMap<String, Object>(1);
		    modelMap.put("data", user);
				return  modelMap;
	}

第二种情况是传递两个值到后台：
js代码：

$.ajax({
                    url: $path + '/generalquery/qc/setSurveyor',
                    method: 'post',
                    dataType: 'json',
                    contentType:"application/json",
                    data:JSON.stringify({
                    	code: node.code,
                    	surveyor:newValue
                    }), 
                    success: function(data) {
                      
                    },error:function(data){
                    	
                    	alert("数据加载异常"+data.id);
                    }
                });

controller代码

@RequestMapping(method = RequestMethod.POST,value="setSurveyor")
	  @ResponseBody 
	  public Object setSurveyor(@RequestBody QualityControl node) {
		
	  QualityControl  qualityControl=new QualityControl();
	  qualityControl.setCode(node.getCode());
	  qualityControl.setSurveyor(node.getSurveyor());
	  
	  if(node.getCode()!=null&&node.getSurveyor()!=null) {
		qualityControlService.updateSurveyor(qualityControl); 
	  }
	  
	  return MyWebResult.buildSuccess(); 
	  
	  }
