问题 In the spring security generated class UserRole or SecUserSecRole (you could call it whatever you choose) there is a command to make a new UserRole() and save it with .save(flush:flush, insert:true) What does that mean? What is it doing differently from .save(flush:true)? 回答1: From the Grails docs: insert (optional) - When set to true will force Hibernate to do a SQL INSERT, this is useful in certain situations when legacy databases (such as AS/400) are involved and Hibernate cannot detect

问题 I'm working with openCV SVM in Visual Studio. (OpenCV 2.4.4.0) I trained it: mySVM.train(trainingDataMat, labelsMat, Mat(), Mat(), params); Saved it: mySVM.save("classifier.xml"); I'm loading it like this: CvSVM mySVM1; mySVM1.load("C:\classifier.xml"); mySVM1.predict(testingDataMat0,result0); And i want to use in other project.
