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。
### 1.在src/main/java下,新建一个Servlet
~~~
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);
}
}
}
~~~
### 2. 修改web.xml
~~~
<?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>
~~~
### 3. 新建JSP
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
~~~
<%@ 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>登录界面</title>
</head>
<body>
<form action="user?action=login" method="post">
Name:<input type="text" name="name" />
Password:<input type="password" name="password" />
<input type="submit" value="登录" />
</form>
</body>
</html>
~~~
### 4. 测试

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。
2013-04-28 日修改
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
