Spring-MVC-所需要的jar包

这两天因为环境搭建的问题特别苦难，参考了一下网上的各种答案，决定自己试一下Spring-MVC启动所需要的jar包；

因为Spring-MVC是在Spring框架下，索性从零开始我们引入需要的jar包；

maven下创建工程老师还没有讲解，这里采用eclipse的Dynamic Web Project来搭建环境；

首先配置web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3     xmlns="http://xmlns.jcp.org/xml/ns/javaee"
 4     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
 5     id="WebApp_ID" version="3.1">
 6     <servlet>
 7         <servlet-name>springMVC</servlet-name>
 8         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 9         <init-param>
10             <param-name>contextConfigLocation</param-name>
11             <param-value>/WEB-INF/servlet-context.xml</param-value>
12         </init-param>
13         <load-on-startup>1</load-on-startup>
14     </servlet>
15     <servlet-mapping>
16         <servlet-name>springMVC</servlet-name>
17         <url-pattern>/</url-pattern>
18     </servlet-mapping>
19
20     <display-name>Test</display-name>
21     <welcome-file-list>
22         <welcome-file>index.html</welcome-file>
23         <welcome-file>index.htm</welcome-file>
24         <welcome-file>index.jsp</welcome-file>
25         <welcome-file>default.html</welcome-file>
26         <welcome-file>default.htm</welcome-file>
27         <welcome-file>default.jsp</welcome-file>
28     </welcome-file-list>
29 </web-app>

然后配置spring-MVC的xml→servlet-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:beans="http://www.springframework.org/schema/beans"
  xmlns:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    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.xsd">

  <annotation-driven />

  <context:component-scan base-package="spitter" />

  <beans:bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/WEB-INF/views/" />
    <beans:property name="suffix" value=".jsp" />
  </beans:bean>

  <resources mapping="/resources/**" location="/resources/" />

  <!--
  <view-controller path="/" view-name="home" />
  -->

</beans:beans>

启动项目

tomcat8.5启动报错

java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

把spring-web-4.2.3.RELEASE.jar 拖到/WEB-INF/lib/目录下，Refresh一下工程；

再次启动项目后报错

把spring-beans-4.2.3.RELEASE.jar 拖到/WEB-INF/lib/目录下，Refresh一下工程；

再次启动项目后报错

把spring-core-4.2.3.RELEASE.jar 拖到/WEB-INF/lib/目录下，Refresh一下工程；

再次启动项目后报错
