SSM專案的環境搭建：

一、專案的目錄結構如下：

二、匯入的jar包：WEB-INF/lib下

三、resources下的幾個配置檔案+WEB-INF下的web.xml檔案需要自己配置：

wei.xml:

<?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_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>pmis</display-name>
 
 <!-- filter 中文編碼配置 -->
	<filter>
		<filter-name>characterEncoding</filter-name>
		<filter-class> org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
		  <param-name>encoding</param-name>
		  <param-value>UTF8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>characterEncoding</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
  
  
  <!-- 載入spring配置-->
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 預設路徑是WEB-INF下的applicationContext.xml,此處建立spring配置檔案為：  beans.xml -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:beans.xml</param-value>
  </context-param>
  
  
  <!-- springmvc配置 -->
  <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:springmvc.xml</param-value>
      </init-param>
  </servlet>
  <servlet-mapping>
      <servlet-name>springmvc</servlet-name>
      <url-pattern>*.do</url-pattern>
  </servlet-mapping>
 
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>
 

beans.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 
		http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 
		http://www.springframework.org/schema/context 
		http://www.springframework.org/schema/context/spring-context-4.0.xsd

<!-- 需要掃描的包 -->
<context:component-scan base-package="cn.com.lanou.service" />
<context:component-scan base-package="cn.com.lanou.dao" />

<!-- 第一步：配置資料庫連線資源 檔案和資料庫連線池-->
<!-- 載入資料庫連線資原始檔 -->
<context:property-placeholder location="classpath:jdbc.properties"/>  
<!-- 配置資料庫連線池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="${jdbc.driver}"></property>
    <property name="jdbcUrl" value="${jdbc.url}"></property>
    <property name="user" value="${jdbc.username}"></property>
    <property name="password" value="${jdbc.password}"></property>
</bean>


<!-- 第二步：建立SqlSessionFactory,生產sqlSession -->
<bean id="SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="configLocation" value="classpath:mybatis.xml"></property>
</bean>

<!-- 配置mapper掃描器、對映檔案，由於對映檔案mybatis.xml可以為空，此處需要配置dao介面的具體對映檔案路徑 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="cn.com.lanou.dao"></property>
    <property name="SqlSessionFactoryBeanName" value="SqlSessionFactory"></property>
</bean>

</beans>
 

mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

其中，配置資料來源時，用到的資料庫連線的資原始檔jdbc.properties:
jdbc.url = jdbc\:mysql\://localhost:3306/lanou
jdbc.driver = com.mysql.jdbc.Driver
jdbc.username= root
jdbc.password= 123456
 

日誌檔案log4j.properties（不需要自己手寫）
log4j.rootLogger=debug,stdout,logfile
### \u628A\u65E5\u5FD7\u4FE1\u606F\u8F93\u51FA\u5230\u63A7\u5236\u53F0 ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout
### \u628A\u65E5\u5FD7\u4FE1\u606F\u8F93\u51FA\u5230\u6587\u4EF6\uFF1Ajbit.log ###
log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.File=D:/test.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %F %p %m%n
 
###\u663E\u793ASQL\u8BED\u53E5\u90E8\u5206
log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.logger.java.sql=debug

四、編寫一個測試類：SSMTest.java

package cn.com.lanou.controller;

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

@Controller
public class SSMTest {

	@RequestMapping("/SSMtest")
	public String test(){
		return "HelloSSM";
	}
	
}

返回檢視：HelloSSM.jsp
