1.创建项目

SpringMVC项目构建（Spring框架下） - 图1

2.添加依赖

  1.   <dependencies>
  2.     <dependency>
  3.       <groupId>junit</groupId>
  4.       <artifactId>junit</artifactId>
  5.       <version>4.11</version>
  6.       <scope>test</scope>
  7.     </dependency>
  8.     <dependency>
  9.       <groupId>org.springframework</groupId>
  10.       <artifactId>spring-context</artifactId>
  11.       <version>5.2.7.RELEASE</version>
  12.     </dependency>
  13.     <dependency>
  14.       <groupId>org.springframework</groupId>
  15.       <artifactId>spring-webmvc</artifactId>
  16.       <version>5.2.7.RELEASE</version>
  17.     </dependency>
  18.   </dependencies>

3.在webapp下的WEB-INF下配置web.xml

  1. <!DOCTYPE web-app PUBLIC
  2.  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
  3.  "http://java.sun.com/dtd/web-app_2_3.dtd" >
  5. <web-app>
  6.   <display-name>Archetype Created Web Application</display-name>
  9.   <servlet>
  10.     <servlet-name>springmvc</servlet-name>
  11.     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  12.     <init-param>
  13.       <param-name>contextConfigLocation</param-name>
  14.       <param-value>classpath:dispatcher-servlet.xml</param-value>
  15.     </init-param>
  16.   </servlet>
  18.   <servlet-mapping>
  19.     <servlet-name>springmvc</servlet-name>
  20.     <url-pattern>/</url-pattern>
  21.   </servlet-mapping>
  22. </web-app>

4.在resources下配置dispatcher-servlet.xml 配置自动注解和视图解析器

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="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.        xmlns:mvc="http://www.springframework.org/schema/mvc"
  6.        xmlns:aop="http://www.springframework.org/schema/aop"
  7.        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
  8.        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
  9.        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
  10.        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
  12.     <context:component-scan base-package="com.note.spring"/>
  14.     <mvc:annotation-driven/>
  16.     <!-- 定义视图解析器 -->
  17.     <bean id="velocityConfig"
  18.           class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  19.         <property name="prefix" value="/" />
  20.         <property name="suffix" value="*.jsp" />
  21.     </bean>
  24. </beans>

5.在com.note.spring目录下建立测试java文件

  1. @RestController
  2. public class HelloController {
  5.     @GetMapping("/test")
  6.     public String test(){
  7.         return "Hello!!!";
  8.     }
  11. }
