整合思路
将工程的三层结构中的JavaBean分别使用Spring容器（通过XML方式）进行管理
1.整合持久层mapper，包括数据源，SqlSessionFactory及mapper代理对象整合
2.整合业务层service，包括事务Bean及service的bean的配置
3.整合表现层Controller，直接使用springmvc的配置
4.web.xml加载spring容器（包含多个XML文件）
核心配置文件
- applicationContext-dao.xml
- applicationContext-service.xml
- springmvc.xml
- web.xml

工程整合
整合Mapper
-
applicationContext-dao.xml（核心）
在classpath下，创建spring目录，然后创建applicationContext-dao.xml
<!-- 加载db.properties -->
<context:property-placeholder
location="classpath:db.properties" />
<!-- 配置数据源 -->
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="maxActive" value="30" />
<property name="maxIdle" value="5" />
</bean>
<!-- 配置SqlSessionFacotory -->
<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 配置数据源 -->
<property name="dataSource" ref="dataSource" />
<property name="typeAliasesPackage" value="com.xxx.ssm.po"></property>
</bean>
<!-- 配置mapper扫描器，SqlSessionConfig.xml中的mapper配置去掉 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 指定扫描的包 -->
<property name="basePackage" value="com.xxx.ssm.mapper" />
</bean>
-
db.properties
在classpath下，创建db.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf8
jdbc.username=root
jdbc.password=root
-
log4j.properties
在classpath下，创建log4j.properties
#dev env [debug] product env [info]
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
整合Service
-
applicationContext-service.xml
在spring文件夹下创建applicationContext-service.xml，文件中配置service。在这个配置文件中，需要配置service的bean和事务管理。
<!-- 扫描Service -->
<context:component-scan
base-package="com.xxx.ssm.service" />
<!-- 配置事务 -->
<!-- 事务管理器，对mybatis操作数据库进行事务控制，此处使用jdbc的事务控制 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 指定要进行事务管理的数据源 -->
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 通知 -->
<tx:advice id="txAdvice"
transaction-manager="transactionManager">
<tx:attributes>
<!-- 传播行为 -->
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="del*" propagation="REQUIRED" />
<tx:method name="remove*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="modify*" propagation="REQUIRED" />
<tx:method name="find*" read-only="true" />
<tx:method name="query*" read-only="true" />
<tx:method name="select*" read-only="true" />
<tx:method name="get*" read-only="true" />
</tx:attributes>
</tx:advice>
<!-- aop -->
<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* *..*.*ServiceImpl.*(..))" />
</aop:config>
整合Controller
Spring和springmvc之间无需整合，直接用springmvc的配置
-
web.xml
在web.xml中添加springmvc的配置
在web.xml中，使用监听器来对spring的配置文件进行加载
<!-- 配置前端控制器 -->
<servlet>
<servlet-name>ssm</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ssm</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 指定持久层和业务层的spring配置文件路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
-
springmvc.xml
在spring包下创建springmvc.xml文件
<!-- 配置处理器Bean的读取 -->
<!-- 扫描controller注解,多个包中间使用半角逗号分隔 -->
<context:component-scan base-package="com.xxx.ssm.controller"/>
<!-- 配置三大组件之处理器适配器和处理器映射器 -->
<mvc:annotation-driven />
<!-- 配置三大组件之视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
