springmvc教程（1）

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">

  </properties>

      <scope>test</scope>
    </dependency>
    <!-- Spring -->
    <dependency>
      <groupId>org.springframework</groupId>

    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>

        <!--Tomcat7插件  -->
        <plugin>

          <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;

@Controller
public 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

http://localhost:8080/weChat/

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。。。。。。
