Servlet入门开发

在开发工具上配置好服务器之后

新建一个web项目,然后就可以开发了

在/Servlet03/WebContent/WEB-INF下配置web.xml

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

<display-name>Servlet03</display-name>

<welcome-file-list>

<welcome-file>index.html</welcome-file>

</welcome-file-list>

<servlet>

<servlet-name>servletlll</servlet-name>

<!-- 对应的servlet类 /注意格式中间用的是点-->

<servlet-class>com.zrkc.server.controller</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>servletlll</servlet-name>

<url-pattern>/*</url-pattern>

</servlet-mapping>

</web-app>

编写servlet类/Controller 类

public class controller extends HttpServlet{

protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

req.setCharacterEncoding("utf-8");

resp.setContentType("text/html;charset=utf-8");

PrintWriter pw=resp.getWriter();

pw.print("hello Servlet");

}

}
