一朋友說要修改tomcat的session cookie name，我翻了一下tomcat各個版本的源碼（tomcat4已經沒人用了，所以除外），幫朋友解決了問題，現總結了一下
修改后效果
1、tomcat5修改方法
在啟動項中增加org.apache.catalina.SESSION_COOKIE_NAME參數
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容器標簽上增加sessionCookieName參數
<Context path=”/” docBase=”webapp” reloadable=”false”sessionCookieName=”yoursessionname”></Context>
3、為啥這樣就好用呢？
tomcat5時增加參數對所有Context生效，影響甚大，所以到以后的版本就僅針對Context設置了
tomcat5源碼如下
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的源碼差不多，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);
}
PS:需要修改其它參數可以直接翻看源代碼或查看tomcat在線文檔
