步骤3:编写Servlet 接下来,我们需要编写一个Servlet类,命名为SessionServlet.java,并放置在适当的包中: packagecom.example;importjavax.servlet.ServletException;importjavax.servlet.annotation.WebServlet;importjavax.servlet.http.HttpServlet;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServle...
一个servlet对应一个servlet映射。部署好tomcat之后,启动tomcat就可以通过localhost:8080/h访问到HelloServlet类中get请求的处理。流程:前端浏览器,输入请求地址,然后定位到/h,找到映射配置,<servlet-name>helloServlet</servlet-name>找到,注册的servlet,就可以找到class,找到class,就可以在该calss中找到对应的请求方法。
http://127.0.0.1:8080/examples/servlets/servlet/SessionExample 我们来到Examples样例目录下的servlets下的session执行按钮。 在Thefollowing data is in yoursession中我们来执行name名称和value值来获取我们需要的session会话值。下面的GETbased form 我的理解就是通过GET传值的方法来登陆。所以说这项我们就不用去关注...
