idea搭建springmvc maven项目
jdk:1.8
maven:Bundled (Maven 3)
idea版本：
开始搭建第一个springmvc maven项目
1.点击File->New->Project
2.选择maven->勾选Create from archetype->选中 maven-archetype-webapp->点击next
3.Name:项目名称 Location:本地工作空间 填写后点击next
4.我没下maven所有就用了默认的，如果本地有的话就使用本地的，填好后finish
5.创建好的项目结构如下
5.1.pom.xml如下：
<?xml version="1.0" encoding="UTF-8"?><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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.example</groupId> <artifactId>weChat</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <name>weChat Maven Webapp</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> <spring.version>4.2.4.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.7</version> </dependency> </dependencies> <build> <finalName>weChat</finalName> <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> <plugins> <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.1.0</version> </plugin> <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>3.2.2</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin> <!--Tomcat7插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <uriEncoding>UTF-8</uriEncoding> <path>/weChat</path> <port>8080</port> </configuration> </plugin> </plugins> </pluginManagement> </build></project>
5.2.web.xml如下：
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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> <servlet> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping></web-app>
6.这个时候你会发现少了目录，选中项目右键->new->Directory
7.这个时候你会发现有这四个你熟悉的目录，我只需要前面两个即可
8.resource下创建mvc.xml文件，我的如下：
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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> <servlet> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping></web-app>9.创建controller类
package com.test.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class HelloController { @RequestMapping(value = "/test") public String test(){ return "test"; }}10.WEB-INF下创建views文件夹后添加test.jsp页面
<html><body><h2>Hello World! weChat</h2></body></html>11.现在的目录如下：
12.使用Tomcat7插件配置启动项目；点击Add Configuration
13.点击+-》点击Maven
14.Name:项目名称 Working directory:工作空间 Command line:启动命令 填完后点击ok
15.启动成功
16，访问页面
17.访问页面http://localhost:8080/weChat/test.do
18.一个springmvc项目就创建成功啦，你也试试吧。。。。。。
