代码说明：

说明：  因为某些国家的进口管制限制，Java发布的运行环境包中的加解密有一定的限制。比如默认不允许256位密钥的AES加解密，解决方法就是修改策略文件。(Because of the restrictions of import control in some countries, there are some restrictions on the encryption and decryption in the operating environment package released by Java. For example, AES encryption and decryption of 256 bit key is not allowed by default. The solution is to modify the policy file.)
