Tomcat uses Redis to store session details

Tomcat Redis session Github address.

Download the Commons-pool2-2.2.jar,jedis-2.5.2.jar,tomcat-redis-session-manager-2.0.0.jar three packages and put them under the Lib directory under the Tomcat directory.

Modify the Context.xml file under Tomcat's Conf directory.

Insert the following code in the context.

The code is as follows	Copy Code
<valve classname= "Com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve"/> <manager classname= "Com.orangefunction.tomcat.redissessions.RedisSessionManager" host= "localhost" Port= "6389" database= "0" Maxinactiveinterval= "60" />

You can view the configuration of GitHub in a more detailed way.

This configures a simple environment that uses Redis to store sessions, and can take the same configuration for clusters.

To test the servlet:

The code is as follows

Copy Code

@WebServlet (urlpatterns = "/myhttp") public class Myhttpservlet extends HttpServlet { @Override protected void doget (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException { Get session HttpSession HttpSession = request.getsession; Httpsession.setattribute ("name", "name"); Set to 0 never expires Httpsession.setmaxinactiveinterval (1000); Make httpserssion Invalid Httpsession.invalidate; System.out.println (Httpsession.getid); Response.getWriter.print ("http"); } }

Start Tomcat, access http://localhost:8080/myhttp can be seen under Redis

The proof environment has been configured successfully and can be used.
