SpringMVC-----使用Maven创建Web项目
1.创建一个Maven的project
2.不使用骨架，去掉勾
3.这里的Packing 选择 war的形式
由于packing是war包，那么下面也就多出了webapp的目录
4.由于我们的项目要使用eclipse发布到tomcat下面，这里我们需要先把项目转成dynamic web project
在我们的项目上点击右键，选择properties 并找到 Project Facets ，并点击Convert to faceted form… 如下图
然后勾选Dynamic Web Module 并点击ok 如下图：(3.0只有tomcat7才支持)
接下来观察我们的项目结构，多了一个WebContent目录
虽然此时我们可以发布到tomcat中，但这不符合maven的结构，我们还要做如下修改
把上图WebContent下面两个目录 META-INF ，WEB-INF 直接剪切到src/main/webapp目录下，并删掉WebContent目录，那么现在的项目结构如下图
5.然后我们要修改发布规则，右键点击项目， 选择 Deployment Assembly
选择WebContent，把它remove掉，测试类我们也不需要发布，test的两个目录页可以remove
接着重新指定一个web的路径，点击add，选择Folder -- 〉 next
在src下找到webapp目录，然后finish
最后一步，我们要把当前的build path 指向 Maven Dependency， 直接点击add，选择Java Build Path Entries 然后next
然后再点击finish完成
完成后如下图：
至此一个基于maven的webapp就建立好了，并可以直接从eclipse中发布到tomcat中
下面新界面测试一下
1.修改pom.xml
添加完代码后，右击项目-》Maven-》Update Project
<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>cn.itsource</groupId> <artifactId>springmvc-shop</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>springmvc-shop Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>4.3.13.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <!-- pring IOC的基础实现，包含访问配置文件、创建和管理bean等 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> </dependencies> <build> <finalName>springmvc-shop</finalName> </build> </project>
2.修改web.xml配置文件
<?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" id="WebApp_ID" version="3.0"> <display-name>springmvc</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 配置HiddenHttpMethodFilter,可以把POST请求转为DELETE或PUT请求 --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置DispatcherServlet --> <servlet> <servlet-name>springDispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- contextConfigLocation配置springmvc加载的配置文件(配置处理器，映射器，适配器等等) 默认加载的是/WEB-INF/servlet名称-servlet.xml(即springDispatcherServlet-servlet.xml) --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 第一种：*.action 访问以.action结尾由DispatcherServlet进行解析 第二种：/. 所有访问的地址都由DispatcherServlet进行解析，对于静态文件的解析需要配置不让DispatcherServlet进行解析 第三种：/*. 这样配置不对，使用这种配置，最终要转发到一个jsp页面时，仍然会由DispatcherServlet解析jsp地址，不能根据jsp页面找到handler，会报错 --> <servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
3.添加springmvc.xml文件
<?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:aop="http://www.springframework.org/schema/aop" xmlns:c="http://www.springframework.org/schema/c" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:task="http://www.springframework.org/schema/task" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" 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-4.3.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.3.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.3.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.3.xsd"> <!-- 配置注解驱动 --> <mvc:annotation-driven /> <!-- 配置自定义扫描的包 --> <context:component-scan base-package="com.springmvc"></context:component-scan> <!-- 配置视图解析器：如何把handler方法返回值解析为实际的物理视图 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
4.新建一个HelloWorld的Controller
package com.springmvc.handler; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /* 指定url地址 * 通过前缀 + returnValue + 后缀 * prefix + returnValue + suffix * 即：WEB-INF/views/success.jsp * * */ @Controller @RequestMapping("/springmvc") public class HelloWorld { private static final String SUCCESS = "success"; /* * 新建方法 * * */ @RequestMapping(value="/hello") public String paramsMethod() { return SUCCESS; } }
5.添加success.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> </head> <body> <a>success!</a> </body> </html>
6.修改index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> </head> <body> <a href="springmvc/hello">测试</a> </body> </html>
7.右键项目Run As-》Run On Server，启动
测试url
http://localhost:8080/springmvc-shop/
http://localhost:8080/springmvc-shop/springmvc/hello
