帮助程序方法，通过反射来调用方法并将任何异常包装为RuntimeException实例

/**来 自 nowjava - 时  代  Java**/


//package com.nowjava;


import java.lang.reflect.InvocationTargetException;

import java.lang.reflect.Method;


public class Main {

    /**

     * A helper method to invoke a method via reflection and wrap any exceptions

     * as {@link RuntimeException} instances

     *

     * @param method     the method to invoke

     * @param instance   the object instance (or null for static methods)

     * @param parameters the parameters to the method

     * @return the result of the method invocation

            Object... parameters) {

        }
