IntelliJ idea 2017-Beginner's SPRINGMVC project to build a simple maven

One, I use the tool is IntelliJ idea +tomcat8+jdk8

Two

1. First create a MAVEN Web project

Next

Next

Click "Finish"

Add the packages that depend on the pom.xml.

1 <?XML version= "1.0" encoding= "UTF-8"?>2 <Projectxmlns= "http://maven.apache.org/POM/4.0.0"3 Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"4 xsi:schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">5   <modelversion>4.0.0</modelversion>6 7   <groupId>GroupId</groupId>8   <Artifactid>Learnspringmvc</Artifactid>9   <version>1.0-snapshot</version>Ten  One   <!--Packaging Methods - A   <Packaging>War</Packaging> -  -   <Dependencies> the     <Dependency> -       <groupId>Org.springframework</groupId> -       <Artifactid>Spring-core</Artifactid> -       <version>4.2.6.RELEASE</version> +     </Dependency> -     <Dependency> +       <groupId>Org.springframework</groupId> A       <Artifactid>Spring-beans</Artifactid> at       <version>4.2.6.RELEASE</version> -     </Dependency> -     <Dependency> -       <groupId>Org.springframework</groupId> -       <Artifactid>Spring-aspects</Artifactid> -       <version>4.2.6.RELEASE</version> in     </Dependency> -     <Dependency> to       <groupId>Org.springframework</groupId> +       <Artifactid>Spring-webmvc</Artifactid> -       <version>4.2.6.RELEASE</version> the     </Dependency> *     <Dependency> $       <groupId>Org.springframework</groupId>Panax Notoginseng       <Artifactid>Spring-context</Artifactid> -       <version>4.2.6.RELEASE</version> the     </Dependency> +   </Dependencies> A </Project>

If you need to add the packages needed for your project later, add them in this format:

         <dependency>36             <groupid>org.springframework</groupid>37             <artifactId> spring-context</artifactid>38             <version>4.2.6.release</version>39         </dependency >

Once added, right-click the import jar package in the project's Pom.xml file, such as:

2. If your idea tool is configured with local tomcat

If there is no red box in the Web and spring, click on the "+" above to add it up.

When you are done adding,

Add dispatcher Front controller to Web. xml

1 <!DOCTYPE Web-app Public2 "-//sun Microsystems, INC.//DTD Web application 2.3//en"3 "Http://java.sun.com/dtd/web-app_2_3.dtd">4 5 <Web-app>6   <servlet>7     <Servlet-name>Myspringmvc</Servlet-name>8     <Servlet-class>Org.springframework.web.servlet.DispatcherServlet</Servlet-class>9     <Init-param>Ten       <Param-name>Contextconfiglocation</Param-name> One       <Param-value>Classpath:mvc-dispatcher-servlet.xml</Param-value> A     </Init-param> -     <Load-on-startup>1</Load-on-startup> -   </servlet> the   <servlet-mapping> -     <Servlet-name>Myspringmvc</Servlet-name> -     <Url-pattern>/</Url-pattern> -   </servlet-mapping> + </Web-app>

Note that the:<url-pattern>/</url-pattern> here don't write <url-pattern>/*</url-pattern>

The Mvc-dispatcher-servlet.xml code is as follows:

1 <?XML version= "1.0" encoding= "UTF-8"?>2 <Beansxmlns= "Http://www.springframework.org/schema/beans"3 Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"4 Xmlns:context= "Http://www.springframework.org/schema/context"5 xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd " >6 7     <Context:component-scanBase-package= "Com.controller"/>8 </Beans>

Create a Java folder, and create a Com.controller package under the Java folder clip.

1  PackageCom.controller;2 ImportOrg.springframework.stereotype.Controller;3 Importorg.springframework.web.bind.annotation.RequestMapping;4 ImportOrg.springframework.web.bind.annotation.ResponseBody;5 ImportOrg.springframework.web.bind.annotation.RequestMethod;6 7 @Controller8@RequestMapping (value = "/main")9  Public classMaincontroller {Ten@RequestMapping (method =requestmethod.get) One @ResponseBody A      PublicString Welcome () { -         return"Test Web"; -     } the}

Last added. You can access it after you launch Tomcat successfully.
