大师养成计划之一：搭建springmvc框架

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。
