java

spring和springmvc整合

web.xml配置springmvc的前端控制器DispatcherServlet
在服务器启动的事件就创建DispatcherServlet
然后根据配置文件创建spring容器和springmvc相关程序

    <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:applicationContext-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>

springmvc指定的配置文件

    <!--0.扫描所有的注解-->
    <context:component-scan base-package="com._520it.crm"/>
    <!--1.配置注解的驱动支持-->
    <mvc:annotation-driven/>
    <!--2.配置静态资源的处理器-->
    <mvc:default-servlet-handler/>
    <!--3.配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    <!--4.引入配置文件-->
    <import resource="classpath:applicationContext.xml"/>
</beans>
