eclipse搭建servlet项目

当搜索Servlet接口时，如果未发现接口则Add library→选择tomcat版本至完成。



代码如下：

package test.servlet;

import java.io.IOException;

import javax.servlet.Servlet;

import javax.servlet.ServletConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

public class TestServlet implements Servlet {

@Override

public void destroy() {

// TODO Auto-generated method stub

}

@Override

public ServletConfig getServletConfig() {

// TODO Auto-generated method stub

return null;

}

@Override

public String getServletInfo() {

// TODO Auto-generated method stub

return null;

}

@Override

public void init(ServletConfig arg0) throws ServletException {

System.out.println("servlet初始化");

}

@Override

public void service(ServletRequest arg0, ServletResponse arg1) throws ServletException, IOException {

System.out.println("service");

}

public TestServlet(){

System.out.println("TestServlet");

}

}

<!-- 配置和映射servlet -->

<servlet>

<!-- Servlet注册的名字 -->

<servlet-name>TestServlet</servlet-name>

<!-- Servlet的全类名 -->

<servlet-class>test.servlet.TestServlet</servlet-class>

</servlet>

<servlet-mapping>

<!-- 需要和某一个servlet节点的servlet-name子节点的名称一致 -->

<servlet-name>TestServlet</servlet-name>

<!-- 映射具体的访问路径：/代表当前web应用的根目录 -->

<url-pattern>/TestServlet</url-pattern>

</servlet-mapping>

</web-app>
