SpringMVC 用http请求的Get和Post请求作为路由的方法的重载方式

@Controller
@RequestMapping("/messageProcessing")
public class WechatPushController {

@Autowired
private WechatPushService wechatPushService;

@Autowired
private WechatOAuthService wechatOAuthService;

@Autowired
private WechatUserService wechatUserService;

/**
* 确认请求来自微信服务器
*/
@RequestMapping(value="/doGet",method=RequestMethod.GET)
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 微信加密签名
String signature = request.getParameter("signature");
// 时间戳
String timestamp = request.getParameter("timestamp");
// 随机数
String nonce = request.getParameter("nonce");
// 随机字符串
String echostr = request.getParameter("echostr");

PrintWriter out = response.getWriter();
// 通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败
if (WechatSignUtil.checkSignature(signature, timestamp, nonce)) {
out.print(echostr);
}
out.close();
out = null;
}

/**
* 处理微信服务器发来的消息
*/
@RequestMapping(value="/doGet",method=RequestMethod.POST)
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 将请求、响应的编码均设置为UTF-8（防止中文乱码）
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");

// 调用核心业务类接收消息、处理消息
String respMessage = wechatPushService.processRequest(request);

// 响应消息
PrintWriter out = response.getWriter();
out.print(respMessage);
out.close();
}
