在上一篇博客里,我们使用Maven构建了一个Web项目,我们在这里写一个简单的Servlet,测试一下。
package com.deppon.text01.action; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class UserServlet extends HttpServlet { private static final long serialVersionUID = 1L; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doPost(request , response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("UTF-8"); response.setContentType("text/html;charset=utf-8"); String action = request.getParameter("action"); if("login_input".equals(action)) { request.getRequestDispatcher("login.jsp").forward(request , response); } else if("login".equals(action)) { String name = request.getParameter("name"); String password = request.getParameter("password"); System.out.println("name->" + name + ",password->" + password); } } }
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" 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"> <servlet> <servlet-name>UserServlet</servlet-name> <servlet-class>com.deppon.text01.action.UserServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>UserServlet</servlet-name> <url-pattern>/user</url-pattern> </servlet-mapping> </web-app>
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>Hello Maven</title> </head> <body> <p>大家好!</p> <a href="user?action=login_input">去登录</a> </body> </html>login.jsp

项目结构如下图所示:
其实,构建完成之后,开发的话,应该和平时开发Web项目是一样的。

之前忘记说明pom文件了,需要添加依赖的:
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.deppon.demo</groupId> <artifactId>test01</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>test01 Maven Webapp</name> <url>http://maven.apache.org</url> <!-- 属性配置 --> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <!-- 依赖配置 --> <dependencies> <!-- 添加JUnit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- 添加Servlet --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> </dependencies> <build> <finalName>test01</finalName> </build> </project>
很抱歉,之前忘记写了.
ps:希望之前看过的朋友再看一下哦
