tomcat修改jsessionid在cookie中的名称

gbvc

　　1、tomcat5修改方法
　　在启动项中增加org.apache.catalina.SESSION_COOKIE_NAME参数

　　linux
JAVA_OPTS=’-Dorg.apache.catalina.SESSION_COOKIE_NAME=yousessionname‘
　　win
set JAVA_OPTS=”-Dorg.apache.catalina.SESSION_COOKIE_NAME=yousessionname“

　　2、tomcat6和tomcat7修改方法相同
　　在Context容器标签上增加sessionCookieName参数

　　<Context path=”/” docBase=”webapp” reloadable=”false” sessionCookieName=”yoursessionname”></Context>

　　3、为啥这样就好用呢？
　　tomcat5时增加参数对所有Context生效，影响甚大，所以到以后的版本就仅针对Context设置了

　　tomcat5源码如下
public final class Globals
/**
* The name of the cookie used to pass the session identifier back
* and forth with the client.
*/
public static final String SESSION_COOKIE_NAME =
System.getProperty(“org.apache.catalina.SESSION_COOKIE_NAME”,
“JSESSIONID”);
　　tomcat6和tomcat7的源码差不多，如下
public class StandardContext
….省略若干
/**
* The name to use for session cookies. <code>null</code> indicates that
* the name is controlled by the application.
*/
private String sessionCookieName;
/**
* Gets the name to use for session cookies.
*
* @return  The value of the default session cookie name or null if not
*          specified
*/
public String getSessionCookieName() {
return sessionCookieName;
}
　　/**
* Sets the name to use for session cookies. Overrides any setting that
* may be specified by the application.
*
* @param sessionCookieName   The name to use
*/
public void setSessionCookieName(String sessionCookieName) {
String oldSessionCookieName = this.sessionCookieName;
this.sessionCookieName = sessionCookieName;
support.firePropertyChange(“sessionCookieName”,
oldSessionCookieName, sessionCookieName);
}
