Reflection 如何使用Groovy在没有继承方法的情况下获取类的所有方法名？

问题

如果没有继承的方法，如何获取类中所有方法的名称

示例

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() {}
}

预期产出

method1_static_void
method2_static_String
method3_void
method4_String

setProperty
getProperty
super$1$wait
super$1$wait
super$1$wait
super$1$clone
getMetaClass
invokeMethod

__$swapInit
method3_void
method1_static_void

this$dist$get$1
super$1$toString

而不是：

def methods = MyClass.methods.collect { it.name }

您只需要声明的非合成方法：

def methods = MyClass.declaredMethods.findAll { !it.synthetic }.name
