使⽤IDEA搭建基于SSM（springmvc+spring+mybatis）的
WEB项⽬
前⾔
本博客的搭建SSM的WEB项⽬内容前提是需要⾃⼰先使⽤IDEA⾃⾏创建基于Maven的WEB⼯程或根据本⼈的另⼀篇博客： 进⾏基于Maven的WEB⼯程创建！
搭建SSM项⽬
1.在创建的Web项⽬的l⽂件中添加SSM的web项⽬依赖，l⽂件中的依赖如下，版本可⾃⾏调整，第⼀次下载依赖可能会稍慢，等待下载完毕即可执⾏下⾯的搭建步骤！

2.在src/main/⽬录下，创建java和resources两个⽂件夹，并在设置其为对应的sources和resources资源⽂件夹
3.在 src\main\webapp\l ⽂件中集成配置spring和springmvc框架
<!-- 集成Spring框架 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring/spring-*.xml</param-value>
</context-param>
<listener>
<!-- 在项⽬启动前初始化当前web应⽤环境 -->
<listener-class>org.t.ContextLoaderListener</listener-class>
</listener>
<!-- 编码过滤器，可以保证项⽬不乱码 -->
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<servlet-name>springmvc</servlet-name>
</filter-mapping>
<!-- 集成SpringMVC框架 -->
<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:l</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>
4.将上述内容添加到l⽂件中会有两处报红，需要在src/main/resources/⽬录下创建spring⽂件夹，在⽂件夹中再创建spring和springmvc对应的xml配置⽂件
5.在第4步创建好的 l⽂件中添加以下内容：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="/schema/beans"
xmlns:xsi="/2001/XMLSchema-instance"
xmlns:context="/schema/context"
xmlns:tx="/schema/tx"
xmlns:aop="/schema/aop"
xsi:schemaLocation="/schema/aop /schema/aop/spring-aop-4.0.xsd
/schema/beans /schema/beans/spring-beans.xsd
/schema/tx /schema/tx/spring-tx-4.0.xs
d
/schema/context /schema/context/spring-context-4.0.xsd">
<!-- 以下IOC配置：创建对象组合对象之间的关系 -->
<!-- 扫描注解类，需要扫描除springmvc组件controller外的所有组件 -->
<context:component-scan base-package="com.hlk.*" >
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 配置c3p0数据源 -->
<bean id="dataSource" class="hange.v2.c3p0.ComboPooledDataSource" >
<property name="driverClass" value="sql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://hadoop01:3306/ct?rewriteBatchedStatements=true&useUnicode=true&characterEncoding=utf8"/>        <property name="user" value="root"/>
<property name="password" value="root"/>
</bean>
<!-- 集成Mybatis框架 -->
<bean id="sqlSessionFactory" class="batis.spring.SqlSessionFactoryBean" >
<property name="configLocation" value="classpath:l" />
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" >
<list>
<value>classpath*:mybatis/mapper-*.xml</value>
</list>
</property>
</bean>
<bean id="mapperScannerConfigurer" class="batis.spring.mapper.MapperScannerConfigurer" >
<property name="basePackage" value="com.hlk.web.dao" />
</bean>
<!-- AOP配置 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- AOP功能增强器 -->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager" >
<tx:attributes>
<!-- spring默认的回滚策略为java.lang.RuntimeException -->
<tx:method name="*" propagation="REQUIRED" isolation="DEFAULT" rollback-for="java.lang.Exception" />
<tx:method name="query*" read-only="true" />
</tx:attributes>
</tx:advice>
<aop:config>
<aop:advisor advice-ref="transactionAdvice" pointcut="execution(* com.hlk..*Service.*(..))"/>
</aop:config>
</beans>
添加以上内容后，会有⼏处报红，需要创建对应dao、service层对应的package（根据个⼈项⽬修改对应的包名即可），并且在
src/main/resources/⽬录下创建mybatis⽂件夹，并在该⽂件夹下⾯创建mybatis的配置⽂件l。上述配置⽂件中我所创建的包
