Grails 4 application.groovy : Is variable declaration allowed? 导致 micronaut 报告的错误

Question

我们正在从 Grails 2 迁移到 Grails 4。非常简化，我们的 application.groovy 是这样的:

def someVar = [:]

environments {

  myGreatApp.brandMap = [
    'dev.analyzor1.com': someVar
  ]
}

这会导致错误，提示未创建变量“someVar”。

ERROR --- [  restartedMain] o.s.boot.SpringApplication               : Application run failed

在将代码从 Config.groovy 和 DataSource.groovy 移动到 application.groovy 之后，我正在迁移一个大型应用程序，这样的事情已经结束。

Is there a workaround for not being able to declare and use a variable in application.groovy? Thanks

Answer 1

好吧，事实证明，只需删除“def”即可使错误消失，如下所示:

someVar = [:] // was: def someVar = [:]

environments {

  myGreatApp.brandMap = [
    'dev.analyzor1.com': someVar
  ]
}

我不能声称它在运行时完全运行，因为转换后的应用程序距离运行还很远，但至少在语法上这是可行的。
