spring-mvc 配置 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:context="http://www.springframework.org/schema/context"

            http://www.springframework.org/schema/context/spring-context-4.3.xsd
            ">
    	
    	<context:component-scan base-package="constxiong" />
    	
    	<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
    	
    	<mvc:annotation-driven />
    	
    	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        	<property name="prefix" value="/WEB-INF/jsp/" />
        	<property name="suffix" value=".jsp" />
        </bean>
    
    </beans>

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" xmlns:web="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_2_5.xsd" id="WebApp_ID" version="2.5">
      
      <display-name>tomcat</display-name>
      
      <servlet>
        <servlet-name>Dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:META-INF/spring-mvc.xml</param-value>
        </init-param>
      </servlet>
      <servlet-mapping>
        <servlet-name>Dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    </web-app>

再给个 controller 和 jsp 就是一个完整的 servlet 应用了。

package constxiong.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    /**
     * controller
     * 
     * @author ConstXiong
     */
    @Controller
    public class IndexController {
    
    	@RequestMapping("index")
    	public String index() {
    		return "index";
    	}
    }

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    	<meta charset="utf-8">
    	<title>ConstXiong</title>
    	<meta name="author" content="ConstXiong" />
    	<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />
    </head>
    <body>
    hello
    </body>
    </html>

执行 maven 打包命令

mvn clean install -DskipTests

打包成功在 target 目录就可以看到 021-jar-tomcat-plugin-0.0.1-SNAPSHOT-war-exec.jar 文件

执行指令即可启动 web 服务

java -jar 021-jar-tomcat-plugin-0.0.1-SNAPSHOT-war-exec.jar
