ssm项目是目前流行的，分为java,recources,webapp三大部分。

（1）Java部分简单来说有controller,dao,mapping,pojo,service五层

1）控制层部分

package com.ssm.normal.controller;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

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

import com.ssm.normal.pojo.User;
import com.ssm.normal.service.IUserService;

@Controller
@RequestMapping("/user")
public class UserController {
	@Resource
	private IUserService userService;
	
	@RequestMapping("/hello")
	public String index(HttpServletRequest request,Model model){
		int userId = Integer.parseInt(request.getParameter("id"));
		User user = this.userService.getUserById(userId);
		model.addAttribute("user", user);
		return "hello";
	}
}

（2）recources部分简单有jdbc,log4j,spring-mvc,spring-mybatis四部分

图
资源部分

1）jdbc部分

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/db_test
username=admin
password=admin
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

2）log4j部分

#LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出位置为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#利用表达式指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#文件到达指定大小的时候，自动产生新文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出全部日志，如果换成DEBUG表示输出DEBUG以上级别日志（不同级别依据情况而定）
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

3)spring-mvc部分

4)spring-mybatis部分

	<bean id="transactionManager"

</beans>

（3）webapp部分简单有静态资源部分，web配置文件，动态页面三部分

web部分

1）静态资源部分

主要是存放js,各类图片等

2）web配置文件部分

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">
	<display-name>Archetype Created Web Application</display-name>
	<!-- Spring和mybatis的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-mybatis.xml</param-value>
	</context-param>
	<!-- 编码过滤器 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<async-supported>true</async-supported>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- Spring监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 防止Spring内存溢出监听器 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>

	<!-- Spring MVC servlet -->
	<servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
		<async-supported>true</async-supported>
	</servlet>
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<!-- 此处可以可以配置成*.do,*.action -->
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>/index.jsp</welcome-file>
	</welcome-file-list>
	<!-- 配置SESSION超时，单位是分钟 -->
	<session-config>
		<session-timeout>30</session-timeout>
	</session-config>

</web-app>

3）动态页面部分

helo.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
	<title>hello world</title>
  </head>
  
  <body>
   hello ${user.userName}
  </body>
</html>

额外部分：pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
