How to access Grails domain classes in Java service layer?

问题 How can I use grails domain classes (which is in groovy) in service layer which is in Java/Spring. When using the grails MVC, everything is fine as I can use controller to access domain objects and call CRUD and other dynamic methods on them. But, what I am wondering is is there a clean way to do it from Java - say the service layer. For example, I may want to develop a reporting framework where I need to use domain objects to access the DB. I Hope the question is clear. This should be a

Grails 3.1.0.M2 Database Reverse Engineering

由 你。 提交于 2019-12-08 23:11:30
Need of help. I am new to Grails, My question is How to do db-reverse-engineer.? I did it in Grails 2.5.1 but I am struggling with Grails 3.1.0.M2 version. Thanks in advance. There's no plugin for Grails 3. I started to convert the older one but it's more work than I was expecting because it has to work with Hibernate 4, and the old plugin only works with Hibernate 3. But the generated files wouldn't be any different in Grails 3 than in Grails 2 since GORM has stayed rather consistent. Since the plugin is only used at build time, and often only once or at most a few times, I recommend that you

How to override the DomainClass.list() in GORM (Grails)

由 点点圈 提交于 2019-12-06 08:11:20
问题 People, I'm facing a problem with grails GORM , my Application is totally dependent of the DomainClass.list() method, it is in all of my create/edit GSPs, but now I need a particular behavior for listing objects. Being more specific I need to filter these lists (All of them) by one attribute. The problem is I'm hoping not to change all the appearances of these methods calling, so is there a way to customize the behavior of the default list() method ? I need it to function just the way it does

Grails 2.4.2 - Dynamically referencing default datasource

由 ⅰ亾dé卋堺 提交于 2019-12-06 05:19:18
问题 This question has been partly answered here but there is still an issue with referencing the default datasource dynamically. I'm working on an internal application that allows developers to modify configuration settings for one of our multi-tenant applications and push those settings from dev to testing, staging and production. Each one of these will have their own datasource, and the Grails app will be installed on each developer's computer. The local datasource will be the default one, and
