使用spring框架创建最简单的java web程序(IDEA商业版）

项目目录如下（IDEA社区版好像无法识别webapp目录？原因见https://www.cnblogs.com/bityinjd/p/9284378.html）：

工具： IDEA

1、首先使用maven创建最简单的maven程序，groupId为com.admin，artifactId为SpringMVC, 然后修改pom.xml,添加jar包

 <?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.</modelVersion>

     <groupId>com.admin</groupId>

     <artifactId>SpringMVC</artifactId>

     <version>1.0-SNAPSHOT</version>

     <packaging>war</packaging>

     <properties>

         <spring.version>4.3..RELEASE</spring.version>

     </properties>

     <dependencies>

         <!--Spring框架核心库 -->

         <dependency>

             <groupId>org.springframework</groupId>

             <artifactId>spring-context</artifactId>

             <version>${spring.version}</version>

         </dependency>

         <!-- Spring MVC -->

         <dependency>

             <groupId>org.springframework</groupId>

             <artifactId>spring-webmvc</artifactId>

             <version>${spring.version}</version>

         </dependency>

         <!-- Servlet核心包 -->

         <dependency>

             <groupId>javax.servlet</groupId>

             <artifactId>javax.servlet-api</artifactId>

             <version>3.0.</version>

             <scope>provided</scope>

         </dependency>

         <!--JSP应用程序接口 -->

         <dependency>

             <groupId>javax.servlet.jsp</groupId>

             <artifactId>jsp-api</artifactId>

             <version>2.1</version>

             <scope>provided</scope>

         </dependency>

     </dependencies>

 </project>

2、在src/main中创建webapp目录，创建index.jsp及WEB-INF目录，WEB-INF目录下创建web.xml

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>最简单的web程序-首页</title>

</head>

<body>

<h1>Hello, World!</h1>

</body>

</html>

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"

         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">

    <!--引导页-->

    <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

</web-app>

3、配置tomcat容器，（tomcat容器配置见https://www.cnblogs.com/best/p/5653916.html#_label3 ）

启动web程序，打开浏览器，输入http://localhost:8080,即可在浏览器中看到Hello World

4、添加一个简单的页面

在src/main/java中添加包com.admin.controller，新建类TestController

package com.admin.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

@RequestMapping("")

public class TestController {

    @RequestMapping("/test")

    public String test() {

        return "test";

    }

}

在src/main/resources下新建servlet解析配置文件spring-servlet.xml

<?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"

       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-4.3.xsd

        http://www.springframework.org/schema/mvc

        http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

    <!-- 自动扫描包，实现支持注解的IOC -->

    <context:component-scan base-package="com.admin" />

    <!-- Spring MVC不处理静态资源 -->

    <mvc:default-servlet-handler />

    <!-- 支持mvc注解驱动 -->

    <mvc:annotation-driven enable-matrix-variables="true" />

    <!-- 配置映射媒体类型的策略 -->

    <bean

            class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">

        <property name="removeSemicolonContent" value="false" />

    </bean>

    <!-- 视图解析器 -->

    <bean

            class="org.springframework.web.servlet.view.InternalResourceViewResolver"

            id="internalResourceViewResolver">

        <!-- 前缀 -->

        <property name="prefix" value="/WEB-INF/views/" />

        <!-- 后缀 -->

        <property name="suffix" value=".jsp" />

    </bean>

</beans>

在/WEB-INF/views/下新建test.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>test</title>

</head>

<body>

<h1>测试</h1>

</body>

</html>

在web.xml中添加对视图解析器，修改后的文件为：

<?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"

         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">

    <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*:springmvc-servlet.xml</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>springmvc</servlet-name>

        <url-pattern>/</url-pattern>

    </servlet-mapping>

    <!--引导页-->

    <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

</web-app>

5、浏览器下输入http://localhost:8080/test

即可看到test.jsp页面
