web容器执行的顺序是context-->listener-->filter-->servlet

因为用了Springmvc 做请求控制 所以首页<welcome-file-list>配置信息放在Springmvc配置的上面

Spring xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 引入jdbc配置文件 -->
<context:property-placeholder location="classpath:conf/jdbc.properties"/>
<!-- 扫描文件 自动将service层和dao层组件注入 -->
<context:component-scan base-package="cn.springmvc.service"></context:component-scan>
<context:component-scan base-package="cn.springmvc.dao"></context:component-scan>
</beans>

1.读取jdbc的配置

2.扫面dao和service就行

mybatis.xml配置

JDBC的配置

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://ip/数据库名?useUnicode=true&amp;characterEncoding=UTF-8
jdbc_username=用户名
jdbc_password=密码

日志配置 log4j.properties

### set log levels ###
#log4j.rootLogger = debug , stdout , D , E
log4j.rootLogger = debug , stdout , D

### output to the console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%n
log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n

### Output to the log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

### Save exception information to separate file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = ERROR
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p

接下来就是接口

package cn.springmvc.dao;

import java.util.List;
import java.util.Map;

import cn.springmvc.model.User;
import cn.springmvc.pageQurty.PageBean;

public interface UserDAO {
/**

* 2015骞�鏈�9鏃�
*/
public int insertUser(User user);
/**
* 鏇存柊鐢ㄦ埛
* @author 鐜嬫灄
* 2015骞�鏈�9鏃�
*/
public int updateUser(User user);
/**
* 鍒犻櫎鐢ㄦ埛

public int deleteUser(Integer id);
/**

public User findUserById(Integer id);
/**

public List<User> findAllUser();

public List<User> findUserByPage(Map<String, PageBean> map);

}

DAO实现类

package cn.springmvc.dao.Impl;

import java.util.List;
import java.util.Map;

import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cn.springmvc.dao.UserDAO;
import cn.springmvc.model.User;
import cn.springmvc.pageQurty.PageBean;

@Service
public class UserDaoImpl implements UserDAO {

@Override
public int insertUser(User user) {
// clark--userMapper.xml 娑擃厼鎳￠崥宥団敄闂傜ame = clark,insertGood---insert id
int result = sessionFactory.openSession().insert(

@Override

}

@Override
public List<User> findAllUser() {

return users;
}

@Override
public List<User> findUserByPage(Map<String, PageBean> map) {

return users;
}

}

Service接口

package cn.springmvc.service;

import java.util.List;
import java.util.Map;

import cn.springmvc.model.User;
import cn.springmvc.pageQurty.PageBean;

public interface UserService {
/**
* 娣诲姞鐢ㄦ埛
* @author 鐜嬫灄
* 2015骞�鏈�9鏃�
*/
public int insertUser(User user);
/**
* 鏇存柊鐢ㄦ埛
* @author 鐜嬫灄
* 2015骞�鏈�9鏃�
*/

public int updateUser(User user);
/**
* 鍒犻櫎鐢ㄦ埛
* @author 鐜嬫灄
* 2015骞�鏈�9鏃�
*/

public int deleteUser(Integer id);
/**
* 鏌ヨ涓�釜鐢ㄦ埛

public User findUserById(Integer id);

* @author 鐜嬫灄
* 2015骞�鏈�9鏃�
*/
public List<User> findUserByPage(Map<String, PageBean> map);
}

service实现类

package cn.springmvc.service.impl;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cn.springmvc.dao.UserDAO;
import cn.springmvc.model.User;
import cn.springmvc.pageQurty.PageBean;
import cn.springmvc.service.UserService;
/**

*/

@Service
public class UserServiceImpl implements UserService{
/**
* 瀹炵幇鎺ュ彛
*/
@Autowired
private UserDAO userDAO;
/**
* 娣诲姞鐢ㄦ埛
*/
@Override
public int insertUser(User user) {

return insertUser;

pageBean.setStartNumber(0);
pageBean.setEndNumber(2);
map.put("page", pageBean);*/
List<User> findUserByPage = userDAO.findUserByPage(map);
return findUserByPage;
}
}

最后controller

package cn.springmvc.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.springmvc.model.User;
import cn.springmvc.service.UserService;

@Controller
@RequestMapping("/home")
public class UserController {
@Autowired
private UserService userService;

@RequestMapping("/user")
public String index(Model model){
List<User> findAllUser = userService.findAllUser();
model.addAttribute("UserAll",findAllUser);
return "index";
}

}

访问

最后配置通过域名或者IP直接访问项目

tomcat conf-->server.xml配置修改

<Connector connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443"/>

在<host><host>中间 加上

<Context path="" docBase="项目名（就是部署到webapps下面的名字）" debug="0"/>

上面项目已经设置首页了 直接输入localhost或者IP或者你申请的域名直接访问项目。
