Eclipse+tomcat（Jetty）+maven 配置Spring mvc图文教程

1、创建Maven工程

如果如下图，请执行步骤2

2、添加Tomcat运行环境

右键项目—Build Path—Configure Build Path 选择Tomcat版本，此时工程目录如下

3、切换JRE版本为本级配置的版本

右键项目—Build Path—Configure Build Path 此时工程目录如下

4、编辑web.xml

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- spring MVC的核心就是DispatcherServlet，使用springMVC的第一步就是将下面的servlet放入web.xml servlet-name属性非常重要，默认情况下，DispatchServlet会加载这个名字-servlet.xml的文件，如下，就会加载 dispather-servlet.xml，也是在WEB-INF目录下。 --> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 设置dispatchservlet的匹配模式，通过把dispatchservlet映射到/，默认servlet会处理所有的请求，包括静态资源 --> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>

5、配置dispatcher-servlet.xml

WEB-INF目录下创建文件夹views，用于存放前端开发资源

<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" default-lazy-init="true"> <!-- 添加注解驱动 --> <mvc:annotation-driven /> <!-- 默认扫描的包路径 --> <context:component-scan base-package="com.rcli.test" /> <!-- mvc:view-controller可以在不需要Controller处理request的情况，转向到设置的View --> <!-- 像下面这样设置，如果请求为/，则不通过controller，而直接解析为/index.jsp --> <mvc:view-controller path="/" view-name="index" /> <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> <!-- 配置jsp路径前缀 --> <property name="prefix" value="/WEB-INF/views/"></property> <!-- 配置URl后缀 --> <property name="suffix" value=".jsp"></property> </bean> </beans>

这里配置为POM中的Group Id

6、配置pom.xml文件

<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>com.rcli.test</groupId> <artifactId>testwebapp</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>testwebapp Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <springversion>3.1.1.RELEASE</springversion> <junitversion>3.8.1</junitversion> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junitversion}</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-asm</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${springversion}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>commons-collections</groupId> <artifactId>commons-collections</artifactId> <version>3.1</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1</version> </dependency> </dependencies> <build> <finalName>testwebapp</finalName> </build> </project>

7、src/main/java下新建包com.rcli.test.controller，在包中新建TestController

package com.rcli.test.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller @RequestMapping("/test") public class TestController { @RequestMapping("/login") public String login() { return "success"; } }

上图中 会在之前 配置的路径下找到相关jsp文件 在WEB-INF/webapp/views目录下新建success.jsp，并且把WEB-INF下的index.jsp文件也移到webapp/views目录下

<html> <body> <h2>Success!</h2> </body> </html>

8、目录

工程目录如下

运行

1、Tomcat运行

右键工程—Debug As— Debug on Server 有时可能会报如下错误 其实相关包是存在的 最后在stackoverflow上找到了解决方法 http://stackoverflow.com/questions/26257642/servlet-webapp-threw-load-exception 首页 URL框中输入后缀test/login

2、Jetty运行

右键工程—Debug As— Run Jetty

浏览器中输入URL
