问题 I'm trying to get all the current user sessions using the app-info plugin but it doesn't compile in Grails 2.5.4 . Is there another way to get this information? I'm new to Grails. This link has some information including a reference to the app-info plugin but it's old and I wasn't able to get anything to compile. UPDATE I've added this custom class in src\groovy\UserSessions : package usersessions import javax.servlet.http.HttpSessionEvent import javax.servlet.http.HttpSessionListener /

问题 My app has an expensive service method, results of which must be 1) checked for errors and 2) presented to a Java applet via a URL (i.e. as opposed to a JavaScript variable). The method result is a string, and the applet is only capable of loading data from a file or URL. I tried to deal with the problem using a session variable: def action1 = { def input = params['input'] def result = expensiveServiceMethod( input ) def failed = result == null session['result'] = result render( view:'view1',

问题 I have a Grails service that sends out e-mails using a 3rd-party service by doing a HTTP call: class EmailService { def sendEmail(values) { def valueJson = values as JSON ... // does HTTP call to 3rd party service } } I've written a unit test to test this service (because an integration test spins up Hibernate and the entire domain framework, which I don't need): @TestFor(EmailService) class EmailServiceTests { void testEmailServiceWorks() { def values = [test: 'test', test2: 'test2'] service

问题 I have a .sql file (initial sql scripts). I have recently deployed application in cloudfoundry, So I want to run these scripts to make application work, Scripts will update more than 5 db tables.

问题 What is the difference between the following actions? def someAction() { User.withTransaction { ... } } and def someAction() { User.withNewTransaction { ... } } When do I use what? When a grails action contains only a Transaction block. In this case I guess withTransaction and withNewTransaction are the same, because each action has its own transaction. Is this true? 回答1: I believe these functions have to do with transaction isolation semantics. The withTransaction function will participate

问题 On Grails 2.0.3, I installed Spring Security Core and created the User, UserRole and Role objects as per the tutorial: http://blog.springsource.org/2010/08/11/simplified-spring-security-with-grails/ All went fine until I decided to add a second datasource in preparation for accessing objects from a different database. DataSource.groovy looks like this: test { dataSource_product { dbCreate = "update" url = "jdbc:mysql://localhost/products" pooled = true driverClassName = "com.mysql.jdbc.Driver
