<!-- 第一种方式 -->
<!-- 根据请求的URL去寻找相应的控制器 -->
解决方案
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.Log
缺jar包了吧 看看WEB-INF/lib下有没有commons logging包
解决方案二：
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.Log
少导包了。apache的commons包
解决方案三：
上一个问题以解决，谢谢两位的指点。但是tomcat启动正常了，访问首页面也成功，可是我从首页面跳转到其他页面怎么会报”404“啊？
网页错误信息如下：
HTTP Status 404 -
type Status report
message
description The requested resource is not available.
Apache Tomcat/8.0.9
页面配置如下：
首页<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
My JSP 'index.jsp' starting page
| 用户名： | |
| 密 码： | |
登录成功和失败页面：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
登陆成功页面
登陆成功
${message }
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
登录失败
登录失败
${message }
controller类文件内容：
public class Logincontroller implements Controller{
private Loginservice ls;
public Loginservice getLs() {
return ls;
}
public void setLs(Loginservice ls) {
this.ls = ls;
}
@Override
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
String username=arg0.getParameter("username");
String password=arg0.getParameter("password");
boolean flag=ls.login(username, password);
ModelAndView mv=new ModelAndView();
if(flag){
//往ModelAndView添加共享变量
mv.addObject("message", "恭喜，你赢啦！");
//设置响应的视图名字
mv.setViewName("success");
}else {
mv.addObject("messege", "抱歉，认证失败");
mv.setViewName("fail");
}
return mv;
}
}
public class Accountcontroller implements Controller{
@Override
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
ModelAndView mav=new ModelAndView();
mav.setViewName("success");
return mav;
}
}
service类文件内容：
public class Loginservice {
public boolean login(String username,String password){
boolean flase=false;
if(username.equals("admin")&&password.equals("admin")){
flase=true;
}
return flase;
}
}
web.xml和spring的xml文件的配置内容和上一个错误发送的相同，请各位帮忙看下啦！
