其他的步骤查看IntelliJ IDEA 配置JDK,Tomcat,MAVEN(三)

给maven工程添加相应的文件夹

(a)打开File|Project Structure…

20180511112435556 or 20180511112625620

(b)打开如图所示:

(C)绑定对应的文件夹是哪个类型的哦!

(1)配置pom.xml文件,添加相应的依赖包

<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.1.0</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>RELEASE</version>
    </dependency>

(2)写控制器代码

package com.hlx.controll;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
/**
 * Created by Administrator on 18-5-9.
 */
@Controller
public class MyController {
    // 请求映射地址 http://localhost:8080/hello，其中 8080 为默认端口
    @RequestMapping(value = "/hello")
    public String goHello(HttpServletRequest request){
        // 输出请求 URL 路径
        System.out.println("请求的路径==>"+request.getRequestURI());
        return "index";  // 返回逻辑名
    }
}

(3)配置springmvc-servlet.xml文件

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.2.xsd ">
    <!-- 声明注解开发方式 -->
   <mvc:annotation-driven/>
    <!-- 包自动扫描 -->
    <context:component-scan base-package="com.hlx.controll"/>
    <!-- 内部资源视图解析器，前缀 + 逻辑名 + 后缀  ctrl+/-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

(4)配置web.xml文件

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app version="2.5" 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_2_5.xsd">
  <display-name>Archetype Created Web Application</display-name>
  <!-- 如果修改 Spring 配置文件的位置和名称，则通过以下方式进行声明全局配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/springmvc-servlet.xml</param-value>
  </context-param>
  <!-- 配置 Spring 监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 配置 DispatcherServlet 对 url 进行过滤 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 显示配置用于解析 DispatcherServlet 的配置文件 -->
    <!-- 如果不显示指定，则 Spring MVC 会自动扫描 WEB-INF 下以 servlet-name 标签声明的名称开头以 servlet 结尾的配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/springmvc-servlet.xml</param-value>
    </init-param>
    <!-- 显示指定加载顺序-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>   <!-- 如果声明 /* 则会拦截所有请求，包括 action 返回的 .jsp 页面 -->
  </servlet-mapping>
  <!-- 配置欢迎页 -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>
