Could not find acceptable representation错误

Could not find acceptable representation：“找不到可接受的形式”

发现可能出发这种异常情况的原因：

请求contenttype=application/json;charset=UTF-8,而这里是produces=text/html

原来代码：

@RequestMapping(value = "/getPage.action", method = RequestMethod.POST, produces = "text/html; charset=UTF-8")

解决方法：去掉produces = "text/html; charset=UTF-8"这段代码或者设置produces=application/json;charset=UTF-8

如果返回的信息是提示信息如“修改成功”等，则produces="text/html;charset=UTF-8"，但如果返回的信息是json数据，则produces="application/json;charset=UTF-8"
