每一个Servlet只有一个实例，多个线程

package com.stono.servlet.synchronize;
import javax.servlet.http.HttpServlet;
public class TestServletC extends HttpServlet {
    private static final long serialVersionUID = 1L;
    protected void doGet(javax.servlet.http.HttpServletRequest req, javax.servlet.http.HttpServletResponse resp) throws javax.servlet.ServletException, java.io.IOException {
        System.out.println(this);
    };
}
