SpringBoot 2 定时任务本机测试成功，但是服务器无法运行。提示错误如下
Unexpected error occurred in scheduled task.
java.lang.NullPointerException: null
详细错误如下，由于项目是放到服务器上才会报错的。所以不得不输出log到服务器上，然后查看log的方法来排除bug。

其实细看我的程序：给出的提示其实很明显了，他提示我的代码底40 行出现了问题。
那么就可以确定问题不再定时任务或者服务器上，只能是在自己的写的代码上出了问题。
查看log好一番尝试之后才发现我写的代码中AES加密的那一部分，代码本机的jdk编译出来和linux 服务器上编译以出来的aes码。完全不一样，管不得总是提示空指针异常，肯定是我根据错误的aes码去请求api服务器肯定请求不到数据的。
