Eclipse下如何配置Tomcat

1、下载Sysdeo Eclipse Tomcat Launcher plugin，把压缩包解压后放在eclipse下的plugins包下。

2、重启eclipse，看到tomcat选项，配置一下路径即可。

3、新建一个tomcat工程，工程名为testServlet。

右击工程新建TestServlet.java文件。

package gameServlet;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.lang.String;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet {

    protected void service(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
//        response.getWriter().println("AAA");
//        response.getWriter().println("hello!");
        //InputStream in = request.getInputStream();
        InputStream in = request.getInputStream();
        byte[] b = new byte[1024];
        in.read(b);
        System.out.println(new String(b).trim());
        in.close();
        OutputStream out = response.getOutputStream();
        String strRequest = "You are welcome!";
        // out.writeUTF("You are welcome!");
        int requestLength = strRequest.length();
        for (int i = 0; i < requestLength; ++i) {
            out.write(strRequest.charAt(i));
        }
        out.close();
//        response.getWriter().println("end!");
    }

}

4、在WEB-INF目录下新建web.xml文件。

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

<web-app>
    <servlet>
        <servlet-name>TestServlet</servlet-name>
        <servlet-class>gameServlet.TestServlet</servlet-class>
    </servlet>
<servlet-mapping>
    <servlet-name>TestServlet</servlet-name>
    <url-pattern>TestServlet</url-pattern>
</servlet-mapping>
</web-app>

 

5、运行，浏览 http://localhost:8080/testServlet/TestServlet。这样就可以看到结果了。
