eclipse,maven
1.新建maven專案,選擇webapp
2.在pom檔案中新增以下內容 1.8是java版本 專案名稱為demo
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.1.2.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>3.1.0</version> </plugin> </plugins> <finalName>demo</finalName> </build>
3.修改web.xml檔案 配置名為demo的servlet
<?xml version="1.0" encoding="UTF-8"?> <web-app 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_3_0.xsd" xmlns:web="http://java.sun.com/xml/ns/javaee" id="WebApp_ID" version="3.0" metadata-complete="true"> <display-name>displayname</display-name> <servlet> <servlet-name>demo</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>demo</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
4.新建demo-servlet.xml檔案 配置viewResolver 在本例中頁面編譯後的位置是/WEB_INF/classes/views/ 如果出現找不到頁面的情況
可以 在dos中,進入專案目錄,mvn package 打包 檢視頁面在包中的位置
5.新建controller<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" 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" default-lazy-init="true"> <!-- 添加註解驅動 --> <mvc:annotation-driven /> <!-- 預設掃描的包路徑 --> <context:component-scan base-package="com.my.demo" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 配置jsp路徑字首 --> <property name="prefix" value="/WEB-INF/classes/views/"></property> <!-- 配置URl字尾 --> <property name="suffix" value=".jsp"></property> </bean> </beans>
package com.my.demo.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorldController {
@RequestMapping("/login")
public String loginFunction(){
return "login";
}
}
6.在resources下,新建views資料夾。新建login.jsp檔案
<%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8" %>
<html>
<head>
<title>標題</title>
</head>
<body>
歡迎來到Springmvc
</body>
</html>
7.tomcat添加當前專案 debug啟動 如果出現404,檢視tomcat的path是不是“demo”
http://localhost:8080/demo/login 訪問頁面
目錄結構如下
