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>

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
