示例代码如下

                if (input.length != 2) {
                    logger.error("The input for execute " + component.toString() + " is not right!");
                    throw new Exception("hehehe");
                }

及

                if (input.length != 2) {
                    logger.error("The input for execute " + component.toString() + " is not right!");
                    throw new Error("hehehe");
                }
