常用到的状态码
2XX
200 OK
这个不需要过多的说明,请求成功,并正常返回。
204
该状态码表示没有内容,响应体payload为空
@RequestMapping("/204test")
@ResponseStatus(value=HttpStatus.NO_CONTENT)
public void ping(HttpServletResponse response) throws Exception
System.out.println("20444");
206
@RequestMapping("/206test")
@ResponseStatus(value=HttpStatus.PARTIAL_CONTENT)
public void ping(HttpServletResponse response) throws Exception
System.out.println("20444");
该状态码应用于断电续传,表示该响应只是全部内容的一部分。
3XX
3XX一般表示重定向
301
重定向,SpringMVC一般会用下面的方式优雅重定向,前后端分离不太常用。
@RequestMapping(value = "/", method = RequestMethod.GET)
public String redirect()
return "redirectPermanent:/home";
302
SpringMVC 返回这个表示,接口和资源有相同的URI,比如你Web模板页面 /user/data页面,controller里又有一个/user/data 接口。就会返回302。
这个状态码下要么改接口的路径,要么改文件路径。代价小的从优。
4XX
400
SpringMVC 这个一般是请求表单参数名和服务端接收的表单的类型对应不上,
比如:服务端要的是Date类型,但是前端传的是字符串,倒置服务端无法理解请求语义;本来要返回json,但是忘了加@ResponseBody;ajax请求的链接后边忘了加参数。
401
SpringMVC 集成SpringSeacurity,如果有资源是当前用户未授权的,那么就会返回401
403
SpringMVC 集成SpringSeacurity,如果有资源当前用户没有访问权限,那么就会返回403。
5XX
500
这个是后台程序有bug,导致无法正常返回。
503
这个问题很古老了,其实是Tomcat中需要部署的是war包,而不是jar包。因为没有在war包找到路径对应的服务,所以报503。
