java的mvc框架？創建后如果index.jsp報錯重新新建就好。
添加jstl servlet springmvc相關配置
pom.xml
<!-- servlet --><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency><!-- end servlet --><!-- spring mvc --><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.3.12.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.12.RELEASE</version></dependency><!-- end spring mvc --><!-- jstl --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!--end jstl -->
web.xml

Spring mvc，創建兩個xml ? ? ? ? applicationContext.xml用于配置數據庫、事物等，dispatcher-servlet.xml配置試圖層相關
applicationContext.xml ?先空起
