问题 In Grails 3.3.3, when I run generate-all for a domain class, a Service Interface is generates (versus the actual Service Class from Grails 2.x). I actually didn't notice it until I tried to add a method to my service. The interface gets placed in the services folder where the service would live. I actually do like the interface but I still want the service and the default implementations. How can I have both an interface and implementation live in the services folder if the interface already

问题 I'm new to Grails,but i have some problems... so i've started to install all of what is required to make it work : jdk8, setting the JAVA_HOME variable etc.. then i've installed Grails, created a new app with it and trying to run it,without modifying it, just to see if Grails was working fine, but unfortunately, nothing happened .. not even errors.. I've tried making it work changing the jdk to 1.7 version because I’ve read that it could be the main issue, but it's still the same.. Even when

问题 I'm working on containerizing an existing application built on grails. I've been able to successfully build the project within a debian:stretch image (yes, I know that's old, but the project was originally built with old versions of just about everything) with gradle , maven , and default-jdk installed. However I'm unsure if that means I don't need grails. When I try grails --version from a command line prompt within the container it says "bash: grails: command not found". There does not

问题 Let's say I have classes similar to domain classes in my application with some Long, Double, Date and String fields. These classes extend base class with some common fields and few common methods. Whenever I access class field (though getter) that is String, I want to make some changes to the value returned (for example remove html tags). Is there a better way than making implementations of getters for each fields of String type? What about inherited fields? 回答1: Don't change default getter

问题 I'm writing a Grails 2.2.1 integration test using the Spock plugin, in which I am trying to post two sets of data to the same controller endpoint: when: "The user adds this product to the inventory" def postData = [productId: 123] controller.request.JSON = postData controller.addToInventory() and: "Then they add another" def secondPostData = [productId: 456] controller.request.JSON = secondPostData controller.addToInventory() then: "The size of the inventory should be 2" new JSONObject(

问题 I'm kind of new to grails and I'm having a lot of trouble with joining two existing tables through domain objects that have been created off of those tables. Does anyone know how to do this in grails? Here are what the tables look like and an example of how I need the joined table to look. Thanks in advance for the help. Table1{ field1table1 } Table2{ field1table2 field2table2 } I need to join these 2 tables where field1table1 = field1table2 and the resulting table join I need to look like

问题 In a previous version of grails I was able to use the groovy enhanced version of java.util.Date found here here. After upgrading to grails 4, all those methods throw no signature of method on java.util.Date. Somehow the groovy additions aren't being picked up. def fdate=new Date(); out << fdate.format("MM/dd/yyyy") //No signature of method: java.util.Date.format() 回答1: Add a dependency to groovy-dateutil to your build.gradle : runtime 'org.codehaus.groovy:groovy-dateutil' The relevant
