問題如何在不使用Groovy繼承方法的情況下獲取類的所有方法名稱？
你怎麼能得到的類的所有方法的名字沒有繼承的方法？
例
def methods = MyClass.methods.collect { it.name }
println methods.each { println it }
assert ["method1_static_void", "method2_static_String", "method3_void", "method4_String"].sort() == methods.sort()
class MyClass {
public static void method1_static_void() {}
public static String method2_static_String() {}
public void method3_void() {}
private String method4_String() {}
}
預期輸出
method1_static_void
method2_static_String
method3_void
method4_String
實際輸出
setProperty
getProperty
super$1$wait
super$1$wait
super$1$wait
super$1$clone
getMetaClass
invokeMethod
setMetaClass
__$swapInit
method3_void
method1_static_void
method2_static_String
this$2$method4_String
this$dist$invoke$1
this$dist$set$1
this$dist$get$1
super$1$toString
super$1$notify
super$1$notifyAll
super$1$getClass
super$1$equals
super$1$hashCode
super$1$finalize
wait
wait
wait
equals
toString
hashCode
getClass
notify
notifyAll
[setProperty, getProperty, super$1$wait, super$1$wait, super$1$wait, super$1$clone, getMetaClass, invokeMethod, setMetaClass, __$swapInit, method3_void, method1_static_void, method2_static_String, this$2$method4_String, this$dist$invoke$1, this$dist$set$1, this$dist$get$1, super$1$toString, super$1$notify, super$1$notifyAll, super$1$getClass, super$1$equals, super$1$hashCode, super$1$finalize, wait, wait, wait, equals, toString, hashCode, getClass, notify, notifyAll]
Assertion failed:
assert ["method1_static_void", "method2_static_String", "method3_void", "method4_String"] == methods
