SSM整合环境搭建demo

1.项目目录结构

2.项目中用的jar包

3.web.xml（其中主要配置spring与springmvc）

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
 <web-app id="WebApp_ID">
     <!-- spring配置 -->
     <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:applicationContext.xml</param-value>
     </context-param>
     <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>

     <!-- 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-servlet.xml</param-value>
         </init-param>
         <load-on-startup>1</load-on-startup>
     </servlet>
     <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern>/</url-pattern>
     </servlet-mapping>
 </web-app>

4.spring配置文件applicationContext.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:tx="http://www.springframework.org/schema/tx"
     xmlns:aop="http://www.springframework.org/schema/aop"
     xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"
     xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
         http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd
         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

     <context:component-scan base-package="com.hxlz">
         <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
     </context:component-scan>

     <context:property-placeholder location="classpath:jdbc.properties" />

     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
         <property name="user" value="${jdbc.user}"></property>
         <property name="password" value="${jdbc.password}"></property>
         <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
         <property name="driverClass" value="${jdbc.driverClass}"></property>
         <property name="initialPoolSize" value="${jdbc.initPoolSize}"></property>
         <property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>
     </bean>

     <bean id="transactionManager"
         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
         <property name="dataSource" ref="dataSource"></property>
     </bean>

     <tx:annotation-driven transaction-manager="transactionManager" />

     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
         <property name="dataSource" ref="dataSource" />
         <!-- 指定mybatis配置文件 -->
         <property name="configLocation" value="classpath:mybatis-config.xml"></property>
     </bean>

     <mybatis-spring:scan base-package="com.hxlz.mapper"/>
 </beans>

5.springmvc配置文件springMVC-servlet.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:mvc="http://www.springframework.org/schema/mvc"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

     <!-- 只扫描标了controller注解的控制器 -->
      <context:component-scan base-package="com.hxlz" use-default-filters="false">
         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
     </context:component-scan>

     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="prefix" value="/WEB-INF/view/"></property>
         <property name="suffix" value=".jsp"></property>
     </bean>

     <mvc:view-controller path="/" view-name="index"/>

     <mvc:annotation-driven></mvc:annotation-driven>
     <mvc:default-servlet-handler/>
 </beans>

6.mybatis配置文件mybatis-config.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>
     <settings>
         <setting name="mapUnderscoreToCamelCase" value="true" />
         <setting name="lazyLoadingEnabled" value="true"/>
         <setting name="aggressiveLazyLoading" value="false"/>
     </settings>

     <typeAliases>
         <typeAlias alias="Employee" type="com.hxlz.bean.Employee" />
     </typeAliases>

 </configuration>

7.具体的业务逻辑的代码（https://github.com/MenghuiLiu/SSM/tree/master/mybatis-spring-springmvc）

内附上mybaits整合spring的官方给的demo（https://github.com/mybatis/jpetstore-6）

希望一起成长，交流，学习。
