在Groovy中,有没有一种方法来修饰每个类以添加跟踪?

class Foo {
    def bar() {
        println "in bar"
    }

    def baz(String name) {
        println "in baz with $name"
    }
}



def decorateMethodsWithLogging(clazz) {
    def mc = clazz.metaClass

    mc.invokeMethod = { String name, args ->
        println "before $name, args = $args"
        def result = mc.getMetaMethod(name, args).invoke(delegate, args)
        println "after $name"
        return result
    }
}


decorateMethodsWithLogging(Foo.class)

def f = new Foo()
f.bar()
f.baz("qux")

before bar, args = []
in bar
after bar
before baz, args = [qux]
in baz with qux
after baz
