springmvc-->整合springmvc

1.先添加web支持

2.添加web.xml依赖

<!--    DispatchServlet-->
    <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-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>

<!--    乱码过滤-->
    <filter>
        <filter-name>encondingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>enconding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encondingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
<!--    Session-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

3.配置好springmvc-servlet.xml

<!--    扫描service层的包-->
    <context:component-scan base-package="com.tang.service"/>

<!--    2.将我们的所有业务类，注入到spring，可以通过配置，或者注解实现-->
    <bean id="BookServiceImpl" class="com.tang.service.BookServiceImpl">
        <property name="booksMapper" ref="bookMapper"/>
     </bean>

<!--    3.声明式事务-->
    <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--        注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
