一、创建项目

我们创建的是一个maven项目，并且它是从原型创建的，如下：

二、环境搭建

（1）引入相关依赖

<dependencies>
  <!-- Spring核心模块 -->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.2.12.RELEASE</version>
  </dependency>
  <!-- SpringWeb模块 -->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>5.2.12.RELEASE</version>
  </dependency>
  <!-- SpringMVC模块 -->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.2.12.RELEASE</version>
  </dependency>
  <!-- Servlet -->
  <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
  </dependency>
  <!-- JSP -->
  <dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
    <scope>provided</scope>
  </dependency>
</dependencies>


<build>
  <plugins>
    <!-- tomcat插件 -->
    <plugin>
      <groupId>org.apache.tomcat.maven</groupId>
      <artifactId>tomcat7-maven-plugin</artifactId>
      <version>2.1</version>
      <configuration>
        <port>8080</port>
        <path>/</path>
        <uriEncoding>UTF-8</uriEncoding>
        <server>tomcat7</server>
        <systemProperties>
          <java.util.logging.SimpleFormatter.format>%1$tH:%1$tM:%1$tS %2$s%n%4$s: %5$s%6$s%n
          </java.util.logging.SimpleFormatter.format>
        </systemProperties>
      </configuration>
    </plugin>
  </plugins>
</build>

（2）在web.xml中配置前端控制器DispatcherServlet

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <!--SpringMVC前端控制器，本质是一个Servlet，接收所有请求，在容器启动时就会加载-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

（3）编写SpringMVC核心配置文件springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">


  <!-- 扫描包 -->
  <context:component-scan base-package="com.itbaizhan"/>


  <!-- 开启SpringMVC注解的支持 -->
  <mvc:annotation-driven/>


</beans>

三、测试是否成功

（1）编写控制器

@Controller
public class MyController1 {
  // 该方法的访问路径是/c1/hello1
  @RequestMapping("/c1/hello1")
  public void helloMVC(){
    System.out.println("hello SpringMVC！");
   }
}
