griffon编程错误:找不到类注释

Question

我正在尝试为一个项目掌握griffon/grails/groovy的诀窍。

我在编译时从我的Test1Controller.groovy文件中得到以下错误：

[griffonc] /home/ironmantis7x/griffon_projects/test1/griffon-app/controllers/test1/Test1Controller.groovy: 14: unable to resolve class Threading ,  unable to find class for annotation
 [griffonc]  @ line 14, column 5.
 [griffonc]        @Threading(Threading.Policy.SKIP)
 [griffonc]        ^
 [griffonc] 
 [griffonc] /home/ironmantis7x/griffon_projects/test1/griffon-app/controllers/test1/Test1Controller.groovy: 14: unable to find class 'Threading.Policy.SKIP' for annotation attribute constant
 [griffonc]  @ line 14, column 16.
 [griffonc]        @Threading(Threading.Policy.SKIP)
 [griffonc]                   ^
 [griffonc] 
 [griffonc] 2 errors                                                                                                             
Compilation error: Compilation Failed 

这是我的控制器文件：

package test1

import griffon.util.GriffonNameUtils as GNU

class Test1Controller {

    def model

    def clear = {
            model.griffonClass.propertyNames.each { name -> model[name] = ''
            }
    }

    @Threading(Threading.Policy.SKIP)
    def submit = {
            java.swing.JoptionPane.showMessageDialog(
            app.windowManager.windows.find{it.focused}, 
            model.griffonClass.propertyNames.collect([]) {
                     name -> "${GNU.getNaturalName(name)} = ${model[name]}"
            }.join('n')
            )
    }

}    

就像我说的，我是griffon/grails/groovy的新手--有人能帮我理解一下我似乎错过了什么吗？

谢谢!

我做了下面建议的更改，现在运行以下命令时得到以下错误: griffon run-webstart -clean：

net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize application. 
    at net.sourceforge.jnlp.Launcher.createApplication(Launcher.java:778)

如何对应用程序进行签名以跳过此错误？

这是我运行griffon -version的配置：

Answer 1

当您使用线程化注释时，您应该在控制器上导入griffon.transform.Threading。

package test1

import griffon.util.GriffonNameUtils as GNU
import griffon.transform.Threading 

class Test1Controller {

    def model

    def clear = {
            model.griffonClass.propertyNames.each { name -> model[name] = ''
            }
    }

    @Threading(Threading.Policy.SKIP)
    def submit = {
            java.swing.JoptionPane.showMessageDialog(
            app.windowManager.windows.find{it.focused}, 
            model.griffonClass.propertyNames.collect([]) {
                     name -> "${GNU.getNaturalName(name)} = ${model[name]}"
            }.join('n')
            )
    }

}    

Answer 2

默认情况下应该会发生应用程序签名。当调用run-webapp时，将从griffon-app/conf/BuildConfig.groovy中获取签名。此签名是在开发中运行时的自签名签名。例如，以下输出是在开发中运行webstart模式而不进行任何配置更改的表单

在您发布的堆栈跟踪中，一定会注意到net.sourceforge.jnlp.LaunchException。您是否正在使用JDK提供的JNLP启动器之外的其他JNLP启动器？另外，运行griffon -version的输出是什么？我的是
