ssm整合

1.导入jar包


mybatis-spring-1.1.1.jar
mybatis-3.2.7.jar
mysql-connector-java-5.1.21.jar
另外一部分：spring的jar 包（依赖commons-logging-1.2.jar）




2. web.xml




 <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:test.xml</param-value>
        </init-param>
  </servlet>
  <servlet-mapping>
  <servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
  </servlet-mapping>
  
  
 3.创建test.xml
  扫描工具
  <context:component-scan base-package="com.hp"/>
  定义mvc驱动
  <mvc:annotation-driven/>
  定义试图解析
  <bean id="viewResolver"
     class="org.springframework.web.servlet.view.InternalResourceViewResolver">
   <property name="prefix" value="/WEB-INF/jsp/"/>
   <property name="suffix" value=".jsp"/>
</bean>

//////整合mybatis
4.配置数据源
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/boardmessage" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
 5.配置sqlSession
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:config/mybatis-config.xml" />
</bean>


6.定义扫描mybatis接口配置的工具
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.hp.mapper"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property> <!--  也可不配置，会自动扫描加载sqlSessionFactory -->
</bean>

7.创建controller
@Controller------写在类名的上面
@RequestMapping("/")

8.创建service
@Service()------写在类名的上面
@Autowired
