问题描述
我正在尝试设置控制器,但遗憾的是无法查看输出...所有内容都正确呈现。当我去 http:// localhost:8080 / CMT / content / edit
我得到一个404页面。从Netbeans运行我的应用程序转到 http:// localhost:8080 / CMT
I'm trying to setup a controller and am unfortunately not able to view the output... everything is rendering correctly. When I go to http://localhost:8080/CMT/content/edit
I get a 404 page. Running my app from Netbeans goes to http://localhost:8080/CMT
package com.cmt.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class Content {
@RequestMapping(value="/content/edit", method=RequestMethod.GET)
public ModelAndView edit(Model model) {
ModelAndView mv = new ModelAndView();
mv.setViewName("index");
return mv;
}
}

我如何调试它,看看哪些有效,哪些无效?
How can I debug this and see what is working and what isn't?
更新
Netbeans中的GlassFish服务器登录显示
The GlassFish server log in Netbeans shows

推荐答案
你的 DispatcherServlet
名为 app
在 web.xml $中映射到
/ *
C $ C>?从我的问题中我看到:
Is your DispatcherServlet
named app
mapped to /*
in web.xml
? From your previous question I see:
<servlet>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/app-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
/ content / edit
网址不匹配 * .htm
模式。尝试 /content/edit.htm
获取可能的解决方法。
/content/edit
URL does not match *.htm
pattern. Try /content/edit.htm
for a possible workaround.
