搭建spring-mvc框架
搭建spring-mvc框架步骤:
1.搭建web项目spring-mvc1
2.引入jar包
3.配置web.xml
3.1拷贝头文件:
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
3.2引入文件
<!-- 引入文件 -->
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring-*.xml</param-value> </context-param>
3.3添加监听
<!-- 添加监听 -->
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
3.4配置中央控制器
<!-- 配置中央控制器 -->
<servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!-- 加载spring-mvc里面加载了视图的解析器 --> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <!-- 保证一启动就被加载 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <!-- 表示拦截所有 --> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 设置不被拦截的请求 ,一般用于 --> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.css</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.gif</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.jpg</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>*.eot</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.svg</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.ttf</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.woff</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.otf</url-pattern> </servlet-mapping>
3.5配置默认页面
4.New一个与src平级的文件夹config 存放:
4.1创建springmvc的核心配置文件SpringMVC-servlet.xml
文件命名规则:中央控制器的名称+”-servlet”
拷贝源码:
4.2创建Spring-mvc.xml
<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-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> </beans>
4.3在Spring-mvc.xml里配置视图解析器
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- webroot到某一指定的文件夹的路径 (前缀)-->
<property name="prefix" value="/WEB-INF/view/"></property>
<!-- 后缀 -->
<property name="suffix" value=".jsp"></property>
</bean>
搭建到这里,运行tomcat,没有异常,搭建成功。
