Grails 无法从嵌套闭包访问私有静态字段

假设我有以下课程：

@Slf4j
class MySuperclass {

    public void testMethod() {
        def test = [1, 2, 3]
        test.each {it ->
            log.info("gab" + it)
            def test2 = [4,5,6]
            test2.each {
                log.info("" + it)
            }
        }
    }
}

然后：

class MySubclass extends MySuperclass {

    public void process() {
        testMethod()
    }
}

调用

mySubclass.process（）

时，我得到一个错误：

No such property log for class: com.ingenuity.app.kang.batch.MySubclass

该错误仅针对test2闭包内的行引发。如果我声明一个公共日志字段，它就可以正常工作。如果我在子类中添加

@Slf4j

注释，它也可以正常工作

我不明白这里发生了什么。这是一个groovy bug吗？ 我发现这个问题可能与此相关，但它不是相同的行为：

您需要在MySuperClass中添加日志依赖项，如：

import groovy.util.logging.Slf4j

@Grapes([
    @Grab(group='ch.qos.logback', module='logback-classic', version='1.0.13') 
])

@Slf4j
class MySuperclass {
...
}

---

处理它的一种方法是将log属性作为类上的静态成员引用。位于的项目证明了这一点

这很有效

我想这个链接可能会给你们一些解决问题的想法。我不认为这是问题所在。这就像在

logback中一样，日志记录工作需要依赖关系，但和不能从嵌套闭包访问私有静态成员无关。谢谢Jeff。是的，如问题中所述，我找到了解决办法。我只是想知道这是一个bug还是我做错了什么。我想是的。你所描述的行为与之相关（可能不完全相同）。谢谢，我没有看到。我会接受答案的。
