通過http向spring的controller傳值總結，網上有很多，總結一下網上沒有的：

1. get和post可用HttpServletRequest.getParameter接收參數；

2. post的json可用@RequestBody HashMap<String,String> json接收；

3. put在spring中有bug，不可用。

實例：

1.get

@RequestMapping(value = "/controller", produces = MediaType.APPLICATION_FORM_URLENCODED_VALUE) public class FormUrlencodedController {private final static Log logger = LogFactory.getLog(FormUrlencodedController.class);@RequestMapping(value = "/action", method = RequestMethod.GET)public ResponseEntityWrapper get(HttpServletRequest req, HttpServletResponse res) {ResponseEntityWrapper rew = new ResponseEntityWrapper();String account = req.getParameter("account");//req.getParameter("account");String password = req.getParameter("password");//req.getParameter("password");return rew;} }
2.post

@RequestMapping(value = "/controller", produces = MediaType.APPLICATION_FORM_URLENCODED_VALUE) public class FormUrlencodedController {@RequestMapping(value = "/action", method = RequestMethod.POST)public ResponseEntityWrapper post(HttpServletRequest req, HttpServletResponse res) {ResponseEntityWrapper rew = new ResponseEntityWrapper();String account = req.getParameter("account");//req.getParameter("account");String password = req.getParameter("password");//req.getParameter("password");return rew;} }

3.put

Spring的RequestMethod.PUT方法接收不到參數

4.post Json

@Controller("MailConfigurationController") @RequestMapping(value = "/email",produces = MediaType.APPLICATION_JSON_VALUE) // public class MailConfigurationController {private final static Log logger = LogFactory.getLog(MailConfigurationController.class);@RequestMapping(value = "/account", method = RequestMethod.POST)@ResponseBodypublic ResponseEntityWrapper createEmailAccount(@RequestBody HashMap<String,String> json, HttpServletRequest req, HttpServletResponse res) {ResponseEntityWrapper rew = new ResponseEntityWrapper();String account =json.get("account");//req.getParameter("account");String password = json.get("password");//req.getParameter("password");return rew;} }
