记录学习的点滴（Spring注解学习过程中问题总结）

1，通过@PathVariable接收数据的乱码问题

设置服务器的编码可以解决，对于Tomcat，只需要修改conf/server.xml文件，添加URIEncoding="UTF-8"即可

<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8088" protocol="HTTP/1.1" redirectPort="8443"/>

2，关于@RequestMapping的实现方式的小结

2.1

<a href="logout.do?method=clearS"><span>注销当前登录</span></a>

java代码中的实现

@Controller("logoutController")public class LogoutControllerImpl {@RequestMapping(value="/logout.do", params="method=clearS", method=RequestMethod.GET)public ModelAndView clearS(HttpServletRequest request){// 清除缓存里面会员的登录信息。request.getSession().removeAttribute("userName");request.getSession().removeAttribute("passowrd");System.out.println("----------登录信息的缓存清除成功----------");return new ModelAndView("pages/logout/logout.jsp");}@RequestMapping(value="/logout.do", params="method=handle")public void handle(HttpServletRequest request, HttpServletResponse response) throws Exception {System.out.println("----------handle()----------");}}

2.2

<a href="pages/logout/clearS.do"><span>注销当前登录</span></a>

java代码中的实现

@Controller("logoutController")public class LogoutControllerImpl {@RequestMapping(value="pages/logout/clearS.do", method=RequestMethod.GET)public ModelAndView clearS(HttpServletRequest request){// 清除缓存里面会员的登录信息。request.getSession().removeAttribute("userName");request.getSession().removeAttribute("passowrd");System.out.println("----------登录信息的缓存清除成功----------");return new ModelAndView("logout.jsp");}@RequestMapping(value="/logout.do", params="method=handle")public void handle(HttpServletRequest request, HttpServletResponse response) throws Exception {System.out.println("----------handle()----------");}}

或者

@Controller("logoutController")@RequestMapping(value="pages/logout", method=RequestMethod.GET)public class LogoutControllerImpl {@RequestMapping(value="clearS", method=RequestMethod.GET)public ModelAndView clearS(HttpServletRequest request){// 清除缓存里面会员的登录信息。request.getSession().removeAttribute("userName");request.getSession().removeAttribute("passowrd");System.out.println("----------登录信息的缓存清除成功----------");return new ModelAndView("logout.jsp");}@RequestMapping(value="/logout.do", params="method=handle")public void handle(HttpServletRequest request, HttpServletResponse response) throws Exception {System.out.println("----------handle()----------");}}

代码结构图

3，@RequestMapping
function toLogout() {
$("#form").attr("action", "clearS.do");
$("#form").submit();
}

...

<a href="javascript:void(0);" onclick="toLogout();"><span>注销当前登录</span></a>

...

</form>

java代码：

@RequestMapping(value="/clearS.do", method=RequestMethod.POST)
public ModelAndView clearS(HttpServletRequest request){

}

form表单里面的method要和@RequestMapping里面的method保持一致
