This is to avoid port conflict problems when the application is already running. Integration tests that hard code the port will need to be altered to use the serverPort property of tests marked with @Integration I was normally getting the integration test url with import grails.util.Holders ... .. . def

问题 I have a grails app doing some stuff in the right way with webflow. So everything goes right in development mode, i can finish the registration and objects are serialized normally. But then, in production mode, deployed on a tomcat 7 with ssl, the following error appears when it's time to persist datas. In a nutshell the serialization don't work. Please help, i have no idea at the moment. The only difference of configuration is that i force https with spring security in production. ----------

问题 My Grails service is having an issue where a swallowed exception unrelated to a transaction is causing the transaction to rollback even when it is unrelated to the persistance of the domain object. In my service I have something along the lines of updateSomething(domainObj) { def oldFilename = domainObj.filename def newFilename = getNewFilename() domainObj.filename = newFilename domainObj.save(flush: true) try { cleanUpOldFile(oldFilename) } catch (cleanupException) { // oh well, log and
