2.Spring整合Mybatis
1） 建表
2） 实体类
3） DAO接口
4） mapper
5） Service接口
6） ServiceImpl @Service @Transactional 注入DAO
7） 编写spring.xml
a. 开启注解扫描
b. 引入小配置文件
c. 创建数据源
d. 创建SqlSessionFactory
e. 创建DAO
f. 创建事务管理器
g. 开启注解式事务生效 <tx:annotation-driven />
spring.xml的代码如下：
<!--开启注解扫描--> <context:component-scan base-package="com.xxx"/> <!--读取配置文件--> <context:property-placeholder location="classpath:jdbc.properties"/> <!--创建数据源--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="${mysql.driverClassName}"/> <property name="url" value="${mysql.url}"/> <property name="username" value="${mysql.username}"/> <property name="password" value="${mysql.password}"/> </bean> <!--创建sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!--注册mapper--> <property name="mapperLocations" value="classpath:com/xxx/mapper/*.xml"/> <!--起别名--> <property name="typeAliasesPackage" value="com.xxx.entity"/> </bean> <!--创建DAO对象--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <property name="basePackage" value="com.xxx.dao"/> </bean> <!--创建事务管理器--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!--开启注解事务生效--> <tx:annotation-driven transaction-manager="transactionManager"/>
3.Spring 整合 SpringMVC
a. 配置web.xml
1） SpringMVC 核心 Servlet 加载springmvc.xml配置文件
2） 配置工厂监听器 ContextLoaderListener
3） 配置全局初始化参数 读取spring.xml
web.xml中代码如下：
<!--配置全局初始化参数--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </context-param> <!--解决中文乱码--> <filter> <filter-name>charset</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> </filter> <filter-mapping> <filter-name>charset</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--配置工厂监听器--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--springmvc的核心servlet--> <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>/</url-pattern> </servlet-mapping>b. 编写springmvc.xml
1） 开启注解扫描
2） 注册处理器映射器和处理器适配器 <mvc:annotation-driven />
3） 配置视图解析器
springmvc.xml中代码如下：
c. 编写控制器Controller 类上 加上 @Controller @requestMapping 注入Service对象<!--开启注解扫描--> <context:component-scan base-package="com"/> <!--注册处理器映射器和处理器适配器--> <mvc:annotation-driven/> <!--配置视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean>
