使用eclipse建立动态网站(Dynamic Web Project)

在WebContent/WEB-INF目录下建立web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>spring</display-name> 
  <servlet>
       <servlet-name>spring</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/spring-servlet.xml</param-value>
		</init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>
   
   <servlet-mapping>
       <servlet-name>spring</servlet-name>
       <url-pattern>/</url-pattern>
   </servlet-mapping>
  
</web-app>

　　接下来建立spring-servlet.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:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
    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">

    <!-- 自动扫描组件 -->
    <context:component-scan base-package="controller" />
    <context:component-scan base-package="service" />

    <!-- 打开注解驱动 -->
    <mvc:annotation-driven />

    <!-- 配置jsp视图解析器 ，需要有jstl这个jar包，否则不能映射 -->
    <bean id="viewResolver"
        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>

在WEB-INF目录下建立jsp文件夹，lib文件夹

lib文件夹中添加jar包

jsp目录下添加页面index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>首页</title>
</head>
<body>${msg}
</body>
</html>

 

 

在Java Resources/src下，建立包controller

创建一个类HomeController

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/hello")
    public String Hello(Model model) {
        model.addAttribute("msg","你好");
        return "index";
    }

}

 

点击运行，即可。
