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。
本文只考虑代码层面的许可限制，暂不考虑逆向破解问题。
<dependency>
<groupId>de.schlichtherle.truelicense</groupId>
<artifactId>truelicense-core</artifactId>
<version>1.33</version>
<scope>provided</scope>
</dependency>
TrueLicense 的 de.schlichtherle.license.LicenseManager 类自带的 verify 方法只校验了我们后面颁发的许可文件的生效和过期时间，然而在实际项目中我们可能需要额外校验应用部署的服务器的 IP 地址、MAC 地址、CPU 序列号、主板序列号等信息，因此我们需要复写框架的部分方法以实现校验自定义参数的目的。

}
例如：私钥库密码为 priwd123456，公钥库密码为 pubwd123456，生成步骤如下：
# 1. 生成私钥库
# validity：私钥的有效期（天）
# alias：私钥别称
# keystore：私钥库文件名称（生成在当前目录）
# storepass：私钥库密码（获取 keystore 信息所需的密码，密钥库口令）
# keypass：别名条目的密码(密钥口令)
keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "pubwd123456" -keypass "priwd123456" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"
# 2. 把私钥库内的公钥导出到一个文件当中
# alias：私钥别称
# keystore：私钥库的名称（在当前目录查找）
# storepass：私钥库的密码
# file：证书名称
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "pubwd123456" -file "certfile.cer"
# 3.再把这个证书文件导入到公钥库，certfile.cer 没用了可以删掉了
# alias：公钥名称
# file：证书名称
# keystore：公钥文件名称
# storepass：公钥库密码
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "pubwd123456"
server:
port: 8080
# License 相关配置
license:
# 主题
subject: license_demo
# 公钥别称
publicAlias: publicCert
# 访问公钥的密码
storePass: pubwd123456
# license 位置
licensePath: E:/licenseTest/license.lic
# licensePath: /root/license-test/license.lic
# 公钥位置
publicKeysStorePath: E:/licenseTest/publicCerts.keystore
# publicKeysStorePath: /root/license-test/publicCerts.keystore
- 将项目打包，然后部署到客户服务器（这里以一台 linux 服务器为例演示）,项目配置文件如下：
server:
port: 8080
# License 相关配置
license:
# 主题
subject: license_demo
# 公钥别称
publicAlias: publicCert
# 访问公钥的密码
storePass: pubwd123456
# license 位置
# licensePath: E:/licenseTest/license.lic
licensePath: /root/license-test/license.lic
# 公钥位置
# publicKeysStorePath: E:/licenseTest/publicCerts.keystore
publicKeysStorePath: /root/license-test/publicCerts.keystore
2. 可以看到第一次启动找不到证书文件，证书安装失败
3. 通过调用前面所写的接口 /license/getServerInfos，获取服务器硬件信息
{
"ipAddress": [
"10.42.1.0",
"10.101.1.4",
"10.42.1.1",
"172.17.0.1"
],
"macAddress": [
"DE-9B-A2-3D-34-C0",
"7C-C3-85-5F-A7-E1",
"0A-58-0A-2A-01-01",
"02-42-3A-E2-79-21"
],
"cpuSerial": "54 06 05 00 FF FB EB BF",
"mainBoardSerial": "2102311TUVCNJC000055"
}
3. 调用前面所写的接口 /license/generateLicense，生成 license 文件
{
"subject":"license_demo",
"privateAlias":"privateKey",
"keyPass":"priwd123456",
"storePass":"pubwd123456",
"licensePath":"/root/license-test/license.lic",
"privateKeysStorePath":"/root/license-test/privateKeys.keystore",
"issuedTime":"2020-10-10 00:00:01",
"expiryTime":"2021-10-09 23:59:59",
"consumerType":"User",
"consumerAmount":1,
"description":"license demo",
"licenseCheckModel":{
"ipAddress":[
"10.42.1.0",
"10.101.1.4",
"10.42.1.1",
"172.17.0.1"
],
"macAddress":[
"DE-9B-A2-3D-34-C0",
"7C-C3-85-5F-A7-E1",
"0A-58-0A-2A-01-01",
"02-42-3A-E2-79-21"
],
"cpuSerial":"54 06 05 00 FF FB EB BF",
"mainBoardSerial":"2102311TUVCNJC000055"
}
}
请求成功后会在设置的 licensePath 目录下生成一个 license.lic 文件
4. 重新启动服务，证书安装成功
为了方便调试，直接在本地运行了，验证证书有效性代码如下（实际生产中，需要在项目代码多处关键位置埋点，校验证书的有效性）：
package com.example.demo;
import com.example.demo.license.LicenseVerify;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class TrueLicenseApplicationTests {
private LicenseVerify licenseVerify;
@Autowired
public void setLicenseVerify(LicenseVerify licenseVerify) {
this.licenseVerify = licenseVerify;
}
@Test
void contextLoads() {
System.out.println("licese是否有效：" + licenseVerify.verify());
}
}
- 在创建证书的情况下，运行证书校验单元测试，打印证书无效的信息
2. 直接将前文在服务器上生成的证书下载到本地，启动项目，打印证书无效的信息（安装证书前会校验，IP地址、MAC 地址、CPU 序列号等前文设置的校验参数，防止证书复制翻版）
3. 重复上述证书创建安装过程后，再次运行证书校验单元测试，证书有效，测试通过
