1.定义一个具有静态方法[myMethod]的类[paramsMethod] 2.在工作流中定义四个变量 string型变量p1,默认值为[wxd],做为[myMethod]方法params的第一个参数 string型变量p2,默认值为[lzm],做为[myMethod]方法params的第二个参数 string型变量p3,默认值为[lzm],做为[myMethod]方法params的第三个参数 string型变...
method.invoke(owner, args):执行该Method.invoke方法的参数是执行这个方法的对象owner,和参数数组args,可以这么理解:owner对象中带有参数args的method方法。返回值是Object,也既是该方法的返回值。 4. 执行某个类的静态方法 public Object invokeStaticMethod(String className, String methodName, Object[] args)throws...
在框架中经常会会用到method.invoke()方法,用来执行某个的对象的目标方法。以前写代码用到反射时,总是获取先获取Method,然后传入对应的Class实例对象执行方法。然而前段时间研究invoke方法时,发现invoke方法居然包含多态的特性,这是以前没有考虑过的一个问题。那么Method.invoke()方法的执行过程是怎么实现的?它的多态又...
