Maven项目SpringMVC环境搭建
创建Maven项目(针对于Eclipse)（右击new-->选择other--->搜索 maven--->选择Maven project点击（Next）下一步创建项目）
点击Finish完成即可
1.导入jar
导入SpringMVC核心jar包
| <dependencies> <!-- https://mvnrepository.com/artifact/org.springframework/spring-context --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.3.18.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-core --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.3.18.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-web --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.3.18.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.18.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> </dependencies> |
2.修改配置web.xml
| <!-- 配置SpringMVC DispatcherServlet(前端控制器) --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- 指定Spring MVC启动所需加载的配置文件 --> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 配置DispatcherServlet所要拦截的url --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> |
3.创建测试类SpringController实现Controller接口重写handleRequest方法代码如下：
| package com.znsd.springmvc.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.Controller; public class SpringController implements Controller{ @Override public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { System.out.println("-------------SpringController------------"); return new ModelAndView("show.jsp");//跳转的页面 } } |
4.增加SpringMVC配置文件（springmvc.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:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- name 代表访问路径 class：指定控制器类 --> <bean name="/indexAction" class="com.znsd.springmvc.controller.SpringController"></bean> </beans> |
5.创建一个index.jsp页面测试indexAction请求是否能进入show.jsp页面
