同台服务器下，配置多个项目，防止登入冲突

-<Host name="localhost" autoDeploy="true" unpackWARs="true" appBase="webapps">

<!-- SingleSignOn valve, share authentication between web applications Documentation at: /docs/config/valve.html -->
<!-- <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> -->
<!-- Access log processes all example. Documentation at: /docs/config/valve.html Note: The pattern used is equivalent to using pattern="common" -->

<!--

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />

-->

<Context sessionCookieName="MYSELF_SESSION1" sessionCookiePath="/" reloadable="true" debug="0" docBase="/home/webServer/apache-tomcat-7.0.78_item1/webapps/ROOT.war" path="/"> </Context>

</Host>

在每个项目的tomcat下的conf文件server.xml添加如上没有注释掉的代码，注意sessionCookieName属性不同项目用不同的名称命名即可，其他属性指定正确就可以了
