在创建的spring mvc工程中，使用idea开发之前需要配置文件包括porm.xml、web.xml、springmvc.xml

1、porm.xml

工程以来的spring库，主要包括spring-aop、spring-web、spring-webmvc，示例配置如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.wlq</groupId><artifactId>mymvctest</artifactId><packaging>war</packaging><version>1.0-SNAPSHOT</version><name>mymvctest Maven Webapp</name><url>http://maven.apache.org</url><dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>6.2.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>6.2.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>6.2.0</version></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><dependency><groupId>org.apache.taglibs</groupId><artifactId>taglibs-standard-jstlel</artifactId><version>1.2.5</version></dependency></dependencies><build><finalName>mymvctest</finalName></build>
</project>

2、web.xml

web.xml主要对控制器DispatcherServlet配置，示例配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="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"><display-name>Archetype Created Web Application</display-name><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/springmvc.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><filter><filter-name>characterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>characterEncodingFilter</filter-name><url-pattern>/</url-pattern></filter-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list>
</web-app>

3、springmvc.xml

springmvc配置是主要对视图解析器配置：

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd"><context:component-scan base-package="controller"/><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id ="internalResourceViewResolver"><property name="prefix" value="/"/><property name="suffix" value=".jsp"/></bean>
</beans>

    配置完成后需要对于tomcat配置需要注意在项目依赖中增加Tomcat引用：项目结构->模块->依赖->添加->2 库。在调试配置中的URL保持和应用程序上下文一致,如下图：
