Groovy 如何向闭包添加属性？

当我尝试向自定义闭包类添加属性时

class MyClosure extends Closure<Object> {
    def myProperty
    MyClosure() {
        super(null)
    }
    Object doCall(final Closure inner) {
        // do something...
    }
}
println new MyClosure().myProperty

这似乎与闭包类有关，闭包类有一些我不太理解的行为，因为当我删除

implements

部分时，没有问题：

class MyClosure {
    def myProperty
}
println new MyClosure().myProperty

那么，当我想向自定义闭包添加属性时，我需要做什么呢？

您需要更改闭包解析策略：

class MyClosure extends Closure<Object> {
    def myProperty = "value"

    MyClosure() {
        super(null)
    }

    Object doCall(final Closure inner) {
        // do something...
    }
}

def closure = new MyClosure()
closure.resolveStrategy = Closure.TO_SELF
println closure.myProperty // value

类MyClosure扩展了Closure{
def myProperty=“值”
MyClosure（）{
超级（空）
}
对象doCall（最终闭包内部）{
//做点什么。。。
}
}
def closure=new MyClosure（）
closure.resolveStrategy=closure.TO_SELF
println closure.myProperty//value

class MyClosure extends Closure<Object> {
    def myProperty = "value"

    MyClosure() {
        super(null)
    }

    Object doCall(final Closure inner) {
        // do something...
    }
}

def closure = new MyClosure()
closure.resolveStrategy = Closure.TO_SELF
println closure.myProperty // value
