一、License简介
License即版权许可证，一般用于收费软件给付费用户提供的访问许可证明。根据应用部署位置的不同，一般可以分为以下两种情况讨论：
- 应用部署在开发者自己的云服务器上。这种情况下用户通过账号登录的形式远程访问，因此只需要在账号登录的时候校验目标账号的有效期、访问权限等信息即可。
- 应用部署在客户的内网环境。因为这种情况开发者无法控制客户的网络环境，也不能保证应用所在服务器可以访问外网，因此通常的做法是使用服务器许可文件，在客户应用启动的时候加载证书，然后在登录或者其他关键操作的地方校验证书的有效性
二、License文件生成服务端
SpringBoot2 使用TrueLicense为客户端生成License许可文件，创建项目名称为cloud-license-server,版本：2.5.5

}2.8 使用JDK自带的Keytool工具生成公私钥证书库
假如我们设置公钥库密码为：public_password1234，私钥库密码为：private_password1234，创建目录，在目录地址输入cmd，文件生成命令如下：
#生成命令
keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -keypass "private_password1234" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"
#导出命令
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"
#导入命令
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"上述命令执行完成之后，会在当前路径下生成三个文件，分别是：privateKeys.keystore、publicCerts.keystore、certfile.cer。其中文件certfile.cer不再需要可以删除，文件privateKeys.keystore用于当前的 cloud-license-serve 项目给客户生成license文件，而文件publicCerts.keystore则随应用代码部署到客户服务器，用户解密license文件并校验其许可信息。
注：此处生成的文件记得拷贝到项目中配置的生成license文件所在的目录
2.9 为客户生成license文件
将 cloud-license-serve 项目部署到客户服务器，通过以下接口获取服务器的硬件信息（等license文件生成后需要删除这个项目。当然也可以通过命令手动获取客户服务器的硬件信息，然后在开发者自己的电脑上生成license文件），使用postman 测试。
