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：
<!--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>
c. 编写控制器Controller 类上 加上 @Controller @requestMapping 注入Service对象
4.部署项目、测试
