Grails 3 call taglib from a service

由 徘徊边缘 提交于 2021-02-08 10:08:00
问题 I'm trying to use grails internal taglib from a service but I receive this error: No signature of method: MyService.message() is applicable for argument types: (java.util.LinkedHashMap) values: [[code:default.app.name]] This is the code I'm using: class MyService { def myMethod() { def appName = message(code: 'default.app.name') } } 回答1: Grails 3 The solution is to inject the grailsApplication object and use its context to get the taglib bean: class MyService { def grailsApplication def

Error in Declaration of service within Grails service

问题 I have concerns about the use of Services within other Services. Some work, but others don't. The problem is that I can't figure out what's wrong.

I wonder if the same is effecting any circular reference creating instability. class UserService { def terceirizadoService def unidadeService def grailsApplication def

Uploading photos using Grails Services

问题 I would like to ask, What would be the most suitable scope for my upload photo service in Grails ? I created this PhotoService in my Grails 2.3.4 web app, all it does is to get the request.getFile("myfile") and perform the necessary steps to save it on the hard drive whenever a user wants to upload an image. To illustrate what it looks like, I give a skeleton of these classes. PhotoPageController { def photoService def upload(){ ... photoService.upload(request.getFile("myfile")) ... } }

问题 I need to get the path of a static resource located in assets/schemas/resource.json in a Grails 3 service.

How to know if a transactional method in a grails service was successful?
