Eclipse configuration SSM framework (non-maven mode)

1. Create project Dynamic web project

Import dozens of jar packages required by the ssm framework. Import into the lib directory.
Note that you must check Generate web.xml when creating a project

2. Integrate the spring framework into the project

1. Create a package spring for placing spring configuration files in the src directory
2. Configure web.xml
   configure spring

	<!-- 配置spring -->
	<!-- 指定配置文件，及所在的目录 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring/applicationContext-*.xml</param-value>
	</context-param>
	<!-- 配置监听器加载spring -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

Configure Spring Mvc

<!-- SpringMVC -->
	<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/spring-mvc.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>

3. Configure springmvc

<!-- 配置注解扫描包 -->
	<context:component-scan base-package="com.lvan.controller" />
	<!-- 处理器适配和映射器 -->
	<mvc:annotation-driven />
	<!-- 内部视图处理器 配置之后，jsp页面就可以放在/WEB-INF/jsp/目录下 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>

4. Create a jdbc.properties configuration file in the src directory to configure jdbc connection information

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/db_ssm
jdbc.username=root
jdbc.password=root

5. Create spring-related configuration applicationContext-dao.xml under the spring package

<!-- 配置jdbc属性引用文件路径 jdbc.properties的路径 效果类似import导包 -->
	<context:property-placeholder location="classpath:jdbc.properties" />
	<!-- 使用阿里巴巴的 DruidDataSource类来创建数据库连接的基本对象-->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>
	<!-- 配置生成Mybatis SqlSessionFactory基本信息 -->
	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 配置mybatis配置所在目录 -->
		<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
		<!-- 指定mybatis的数据源配置 -->
		<property name="dataSource" ref="dataSource" />
	</bean>
	<!-- 配置mybatis中mapper接口所在的包 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.lvan.mapper" />
	</bean>

6. Configure Spring-service

	<!-- 配置事务所在的包 -->
	<context:component-scan base-package="com.lvan.service" />
	<!-- 配置事务 -->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<!-- 开启注解方式管理AOP事务 -->
	<tx:annotation-driven transaction-manager="transactionManager" />
