REDIS+TOMCAT7 Implementing session Sharing

PS: Until 2015-05-12 is not supported TOMCAT8, details see official website: Https://github.com/jcoleman/tomcat-redis-session-manager

Prerequisite: You have deployed Redis, have not learned, can be moved here: http://blog.csdn.net/caiwenfeng_for_23/article/details/45511007

Actually very simple, just a few steps:
1. Configure the context.xml file under Tomcat's conf directory:

1> Single Point Reids configuration

<code class= "Hljs xml has-numbering" style= "display:block; padding:0px; Color:inherit; Box-sizing:border-box; font-family: ' Source Code Pro ', monospace;font-size:undefined; White-space:pre; border-radius:0px; Word-wrap:normal; background:transparent; " > <span class= "hljs-comment" style= "Color:rgb (136, 0, 0); Box-sizing:border-box; " ><!--Jedis Save session--></span> <span class= "Hljs-tag" style= "Color:rgb (0, 102, 102); Box-sizing:border-box; " ><<span class= "Hljs-title" style= "Box-sizing:border-box; Color:rgb (0, 0, 136); " >Valve</span> <span class= "Hljs-attribute" style= "Box-sizing:border-box; Color:rgb (102, 0, 102); " >classname</span>=<span class= "Hljs-value" style= "Box-sizing:border-box; Color:rgb (0, 136, 0); " > "Com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" </span>/></span> <spa n class= "Hljs-tag" style= "Color:rgb (0, 102, 102); Box-sizing:bordeR-box; " ><<span class= "Hljs-title" style= "Box-sizing:border-box; Color:rgb (0, 0, 136); " >Manager</span> <span class= "Hljs-attribute" style= "Box-sizing:border-box; Color:rgb (102, 0, 102); " >classname</span>=<span class= "Hljs-value" style= "Box-sizing:border-box; Color:rgb (0, 136, 0); " > "Com.orangefunction.tomcat.redissessions.RedisSessionManager" </span> <span class= "Hljs-attribute" St Yle= "Box-sizing:border-box; Color:rgb (102, 0, 102); " >host</span>=<span class= "Hljs-value" style= "Box-sizing:border-box; Color:rgb (0, 136, 0); " > "localhost" </span> <span class= "Hljs-attribute" style= "Box-sizing:border-box; Color:rgb (102, 0, 102); " >port</span>=<span class= "Hljs-value" style= "Box-sizing:border-box; Color:rgb (0, 136, 0); " > "6379" </span> <span class= "Hljs-attribute" style= "Box-sizing:border-box; Color:rgb (102, 0, 102); " >database</span>=<span class= "Hljs-valUE "Style=" Box-sizing:border-box; Color:rgb (0, 136, 0); " > "0" </span> <span class= "Hljs-attribute" style= "Box-sizing:border-box; Color:rgb (102, 0, 102); " >maxinactiveinterval</span>=<span class= "Hljs-value" style= "Box-sizing:border-box; Color:rgb (0, 136, 0); " > "</span>/></span></code><ul class=" pre-numbering "style=" Box-sizing:border-box; Position:absolute; width:50px; top:0px; left:0px; margin:0px; padding:6px 0px 40px; border-right-width:1px; Border-right-style:solid; Border-right-color:rgb (221, 221, 221); List-style:none; Text-align:right; Background-color:rgb (238, 238, 238); " ><li style= "Box-sizing:border-box; padding:0px 5px; " >1</li><li style= "Box-sizing:border-box; padding:0px 5px; " >2</li><li style= "Box-sizing:border-box; padding:0px 5px; " >3</li><li style= "Box-sizing:border-box; padding:0px 5px; " >4</li><li style= "Box-sizing:border-box; Padding:0px 5px; " >5</li><li style= "Box-sizing:border-box; padding:0px 5px; " >6</li><li style= "Box-sizing:border-box; padding:0px 5px; " >7</li><li style= "Box-sizing:border-box; padding:0px 5px; " >8</li><li style= "Box-sizing:border-box; padding:0px 5px; " >9</li></ul>

2. Add jar

3. Testing

2> reboot Tomcat: If the session is saved under Tomcat, the session does not exist after the reboot, and if it is saved under Redis, the Tomcat restart has no effect on the session.

3> Remove Session:

Note: The session persistence setting is turned on by default from Tomcat6, and the local session persistence can be turned off in the test, but it is also very simple, in the context.xml file under Tomcat's Conf directory, uncomment the following configuration:

<code class= "Hljs xml has-numbering" style= "display:block; padding:0px; Color:inherit; Box-sizing:border-box; font-family: ' Source Code Pro ', monospace;font-size:undefined; White-space:pre; border-radius:0px; Word-wrap:normal; background:transparent; " > <span class= "hljs-comment" style= "Color:rgb (136, 0, 0); Box-sizing:border-box; " ><!--Uncomment this to disable session persistence across Tomcat restarts--></span> <span class= "h Ljs-comment "style=" Color:rgb (136, 0, 0); Box-sizing:border-box; " ><!--<manager pathname= ""/>--></span></code><ul class= "pre-numbering" style= "box- Sizing:border-box; Position:absolute; width:50px; top:0px; left:0px; margin:0px; padding:6px 0px 40px; border-right-width:1px; Border-right-style:solid; Border-right-color:rgb (221, 221, 221); List-style:none; Text-align:right; Background-color:rgb (238, 238, 238); " ><li style= "Box-sizing:border-box; padding:0px 5px;" >1</li><li style= "Box-sizing:border-box; padding:0px 5px; " >2</li><li style= "Box-sizing:border-box; padding:0px 5px; " >3</li><li style= "Box-sizing:border-box; padding:0px 5px; " >4</li></ul>

You can try running the demo case above.
