首先在myeclipse中建立一个web工程，在底下建一个包，然后写servlet
package com.jspdev.ch7;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorldServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException
{
resp.setCharacterEncoding("UTF-8");
resp.setContentType("text/html;charset=UTF-8");
PrintWriter out=resp.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>helloworld</title>");
out.println("</head>");
out.println("<body bgcolor=\"white\">");
out.println("<hr>");
out.println("helloworld");
out.println("你好 世界");
out.println("</body></html>");
}
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException
{
doGet(req, resp);
}
}
然后在工程的web.xml中进行配置
<servlet>
<servlet-name>HelloWorldServlet</servlet-name>
<servlet-class>com.jspdev.ch7.HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorldServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
最后在浏览器中运行servlet
输入http://localhost:8080/jsp-demo/hello
就OK了！！！
