springmvc的框架搭建及工作流程

1.搭建要点

web.xml:

<servlet-mapping>

    <servlet-name>springDispatcherServlet</servlet-name>

    <url-pattern>/</url-pattern>

 </servlet-mapping>

<servlet-mapping>

     <servlet-name>default</servlet-name>

     <url-pattern>*.css</url-pattern>

</servlet-mapping>

 spring mvc如何访问静态资源需要加入以下代码:

<servlet-mapping>

      <servlet-name>default</servlet-name>

      <url-pattern>*.gif</url-pattern>

</servlet-mapping>

 

<servlet-mapping>

    <servlet-name>default</servlet-name>

     <url-pattern>*.png</url-pattern>

</servlet-mapping>

 

<servlet-mapping>

     <servlet-name>default</servlet-name>

     <url-pattern>*.js</url-pattern>

</servlet-mapping>

 

<servlet-mapping>

      <servlet-name>default</servlet-name>

      <url-pattern>*.html</url-pattern>

</servlet-mapping>

2.springmvc.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:context="http://www.springframework.org/schema/context"

    xmlns:mvc="http://www.springframework.org/schema/mvc"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

 

 

        <!-- 配置自动扫描的包 -->

        <context:component-scan base-package="com.shi.springmvc"></context:component-scan>

 

        <!-- 配置视图解析器 如何把handler 方法返回值解析为实际的物理视图 -->

        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

            <property name = "prefix" value="/WEB-INF/views/"></property>

            <property name = "suffix" value = ".jsp"></property>

        </bean>

</beans>
