maven 创建 sevlet 程序-优快云博客

1>mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp -DgroupId=lei-sample -DartifactId=mysevlet

2>导入maven 工程

3>创建java project：cd mysevlet\src\main; mkdir java

4>右键->maven->update project configuration

5>添加javax.servlet依赖，j2se没有这个package,j2ee才有, mvn resp: http://search.maven.org/#search|ga|1|

6>配置 jetty

</project>

7>添加servlet

package lei.java.sevlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.Servlet;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
 * Get method to display hello world
 *
 */
public class SimpleSevlet implements Servlet{
	ServletConfig servletConfig;
	public void destroy() {
		// TODO Auto-generated method stub
		
	}

	public ServletConfig getServletConfig() {
		// TODO Auto-generated method stub
		return null;
	}
	public String getServletInfo() {
		// TODO Auto-generated method stub
		return null;
	}

	public void init(ServletConfig arg0) throws ServletException {
		System.out.println( "Start:" + arg0.getServletName());
		servletConfig = arg0;
	}

	public void service(ServletRequest arg0, ServletResponse response)
			throws ServletException, IOException {
		 String servletName = servletConfig.getServletName();
	        response.setContentType("text/html");
	        PrintWriter writer = response.getWriter();
	        writer.print("<html><head></head>"
	                + "<body>Hello from " + servletName
	                + "</body></html>");
	}
	
}
