当我在tomcat上部署2个相同的应用程序时，我遇到了问题。战争是一样的，只有应用名称是不同的。
Tomcat随机返回（仅适用于第二个加载的应用）：
错误500

仅当我使用放置在配置 / pardus中的过滤器类时才会出现问题。上次更改：asyncAuditService。
package pardus

def auditService
def sessionRegistry
def asyncAuditService
def filters = {
all(controller:'*', action:'*') {

((HttpServletResponse) response).setHeader("Cache-Control", "no-store, no-cache, must-revalidate");
log.info "username ${session}"
log.info "session user ${session.user}"
log.info "ip address: ${request.getHeader("X-Real-IP")}"
log.info "all: ${sessionRegistry.getAllPrincipals()}"
def allowAlwaysController = ["login","info","logout"]
def user = springSecurityService.currentUser
if(user!=null && !user.enabled && !controllerName.equals('logout')){
redirect(controller:'logout');
return false;
}

redirect(controller:'login');
return false;
}
if (session.is_confirmed!="true" && !controllerName.equals('info') && !controllerName.equals('login') && !controllerName.equals('logout')){
log.info('not confirmed');
redirect(controller:'info',action:'term');
return false;
}
log.info "password o: ${user?.passwordExpired}"

log.info "password o: ${user.passwordExpired}"
flash.error = "NEW_PASSWORD_REQUIED"
redirect(controller:'account',action:'index');
return false;
}
if(!allowAlwaysController.contains(controllerName)){
def role = springSecurityService.currentUser?.getRole()?.authority
log.info "controllerName " + controllerName
log.info "controllerName " + actionName
if(role!=null && (grailsApplication.config.pardus.priv[role][controllerName]==null || !grailsApplication.config.pardus.priv[role][controllerName].contains(actionName))){

flash.error = "BRAK_UPRAWNIEN"

redirect(controller:'dashboard',action:'index');
return false;
}
}
if(grailsApplication.config.pardus.audit){
asyncAuditService.audit(params,request.getHeader("X-Real-IP"),session,request.getHeader("user-agent"))
}
}
