---------------加密生成 新的jar 包后，运行时 ，就需要输入  密码  ，spring boot 打的 jar才可以运行

--------------解密

import io.xjar.boot.XBoot;
import io.xjar.jar.XJar;

import java.io.File;

public class DecryClass {
    // Spring-Boot Jar包解密
    public static void main(String[] args) throws Exception {
        String password = "io.xjar";
        File encrypted = new File("/path/to/read/encrypted.jar");
        File decrypted = new File("/path/to/save/decrypted.jar");
        XBoot.decrypt(encrypted, decrypted, password);
    }
}
