用ajax访问springmvc中方法，为啥返回值出错

dzq584462393 2014-03-18 10:33:44



@RequestMapping(value = "/change/deleteChangeFile.do", method = RequestMethod.POST)

	public void deleteChangeFile(@RequestParam("id") int fileId, Model model) {

		if (logger.isInfoEnabled()) {

			logger.info("deleteChangeFile(int fileId = " + fileId

					+ ", Model model=" + model + ") -  start ");

		}

		

		fileService.deleteChangeFile(fileId);

	}

这个方法不管加上返回值还是不加上都出错。

4楼正解，你没有打@ResponseBodyspringmvc肯定要跳转，而又找不到，就有报错了，打了@ResponseBody就行了

deleteChangeFile方法前加上@ResponseBody注解

$! 你！　　干嘛

这不是异步调用到方法deleteChangeFile 然后进行删除操作，这个方法不是没有返回值吗，出错，有返回值也出错

$.ajax({
		     url :"$!{appRoot}/change/deleteChangeFile.do",
		     type :'post',
		     dataType :'json',
		     contentType: "charset=UTF-8",
		     data:params,
		     error:function(data){
		      	alert("删除出错！！");
		     }
		});

弹出删除出错
