为什么@GrailsCompileStatic 允许调用动态 GORM 查找器而不是 domainClass.withTransaction()？

Question

将 @GrailsCompileStatic 注释添加到方法或 class 允许使用动态 GORM 查找器，例如findAllByIdAndProperty()。但是，添加注释不允许 domainClass.withTransaction()，这也是 GORM AST 添加。为什么？

（使用 grails-2.5.3）

更新（05/10/16 - 10:25AM） @jeff-scott-brown 是对的，它确实可以正常工作，所以这里是失败的代码 @GrailsCompileStatic:

...
RestfulApiService service = ServiceUtils.getService(resourceName)
service.resourceClass.withTransaction { /* do something */ }

(资源Class类型为Class)

错误：

Compilation error: startup failed:
C:\...\myfile.groovy: 100: [Static type checking] - Cannot find matching method java.lang.Class#withTransaction(groovy.lang.Closure). Please check if the declared type is right and if the method exists.
@ line 100, column 13.
           service.resourceClass.withTransaction {
           ^

为什么在这种情况下添加注释后 withTransaction() 会失败？

Why does @GrailsCompileStatic allow calling dynamic GORM finders but not domainClass.withTransaction()?

确实如此。 https://github.com/jeffbrown/withtx/blob/master/grails-app/controllers/demo/DemoController.groovy 处的代码编译。

import grails.compiler.GrailsCompileStatic

@GrailsCompileStatic
class DemoController {

    def index() {
        Person.withTransaction {
            // ...
        }
        render 'Success!'
    }
}
