How to configure Spring-sesssion Custom Cookie by xml -

sorry poor english, current config this:

<bean class="org.springframework.session.web.http.defaultcookieserializer">     <property name="cookiename" value="test_sessionid"></property>     <property name="cookiepath" value="/"></property>     <!-- <property name="domainname" value="example.com"></property> -->     <property name="domainnamepattern" value="^.+?\\.(\\w+\\.[a-z]+)$"></property> </bean> 

i want custom domain,it working while configured domainname property.but when configure domainnamepattern above,it working on localhost , ip address,but no www.example.com test.example.com tks.

it looks not using valid regular expression (the expression escaped java string using xml). expression not match of domains use current domain. try following instead:

<bean class="org.springframework.session.web.http.defaultcookieserializer">     <property name="cookiename" value="test_sessionid"></property>     <property name="cookiepath" value="/"></property>     <!-- <property name="domainname" value="example.com"></property> -->     <property name="domainnamepattern" value="^.+?\.(\w+\.[a-z]+)$"></property> </bean>
