License介绍
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。部署到客户现场，但是客户服务器可以联网，也可以采用办法许可证书进行验证，也可以远程认证-认证服务器提供认证请求，必须走线上认证才可使用。
任何加密都有反编译、破解、跳过的手段。
license授权机制的原理
TrueLicense是一个开源的证书管理引擎。
生成密钥对，使用Keytool生成公私钥证书库。授权者保留私钥，使用私钥对包含授权信息（如使用截止日期，MAC地址等）的license进行数字签名。公钥给使用者（放在验证的代码中使用），用于验证license是否符合使用条件。springboot整合TrueLicense-生成License证书1、引入依赖

/** * @ProjectName LicenseCreatorController * @author Administrator * @version 1.0.0 * @Description 于生成证书文件，不能放在给客户部署的代码里 * @createTime 2022/4/30 0030 18:13 */@RestController@RequestMapping("/license")public class LicenseCreatorController { /** * 证书生成路径 */ @Value("${license.licensePath}") private String licensePath; /** * @title 获取服务器硬件信息 * @description @param osName 操作系统类型，如果为空则自动判断 * @author Administrator * @updateTime 2022/4/30 0030 18:14 */ @RequestMapping(value = "/getServerInfos") public LicenseCheckModel getServerInfos(@RequestParam(value = "osName",required = false) String osName) { //操作系统类型 if(StringUtils.isBlank(osName)){ osName = System.getProperty("os.name"); } osName = osName.toLowerCase(); AbstractServerInfos abstractServerInfos = null; //根据不同操作系统类型选择不同的数据获取方法 if (osName.startsWith("windows")) { abstractServerInfos = new WindowsServerInfos(); } else if (osName.startsWith("linux")) { abstractServerInfos = new LinuxServerInfos(); }else{//其他服务器类型 abstractServerInfos = new LinuxServerInfos(); } return abstractServerInfos.getServerInfos(); } /** * @title 生成证书 * @description * { * "result": "ok", * "msg": { * "subject": "license_demo", * "privateAlias": "privateKey", * "keyPass": "private_password1234", * "storePass": "public_password1234", * "licensePath": "D:/license/license.lic", * "privateKeysStorePath": "D:/license/privateKeys.keystore", * "issuedTime": "2022-04-10 00:00:01", * "expiryTime": "2022-05-31 23:59:59", * "consumerType": "User", * "consumerAmount": 1, * "description": "这是证书描述信息", * "licenseCheckModel": { * "ipAddress": [], * "macAddress": [], * "cpuSerial": "", * "mainBoardSerial": "" * } * } * } * @author Administrator * @updateTime 2022/4/30 0030 18:14 */ @RequestMapping(value = "/generateLicense",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}) public Map<String,Object> generateLicense(@RequestBody(required = true) LicenseCreatorParam param) { Map<String,Object> resultMap = new HashMap<>(2); if(StringUtils.isBlank(param.getLicensePath())){ param.setLicensePath(licensePath); } LicenseCreator licenseCreator = new LicenseCreator(param); boolean result = licenseCreator.generateLicense(); if(result){ resultMap.put("result","ok"); resultMap.put("msg",param); }else{ resultMap.put("result","error"); resultMap.put("msg","证书文件生成失败！"); } return resultMap; }}9、使用Keytool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，则生成命令如下：
## 1. 生成私匙库# validity：私钥的有效期多少天# alias：私钥别称# keystore: 指定私钥库文件的名称(生成在当前目录)# storepass：指定私钥库的密码(获取keystore信息所需的密码) # keypass：指定别名条目的密码(私钥的密码) 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"## 2. 把私匙库内的公匙导出到一个文件当中# alias：私钥别称# keystore：指定私钥库的名称(在当前目录查找)# storepass: 指定私钥库的密码# file：证书名称keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"## 3. 再把这个证书文件导入到公匙库# alias：公钥别称# file：证书名称# keystore：公钥文件名称# storepass：指定私钥库的密码keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"
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 qingfeng-server 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qingfeng-client服务器，用户解密license文件并校验其许可信息。
10、生成license证书
运行项目，项目启动后，通过postmain进行测试：
获取服务器硬件信息
请求地址：
生成license证书
访问地址：
请求时需要在Header中添加一个 Content-Type ，其值为：application/json;charset=UTF-8。参数示例如下
{ "subject": "license_demo", "privateAlias": "privateKey", "keyPass": "private_password1234", "storePass": "public_password1234", "licensePath": "D:/license/license.lic", "privateKeysStorePath": "D:/license/privateKeys.keystore", "issuedTime": "2022-04-10 00:00:01", "expiryTime": "2022-05-31 23:59:59", "consumerType": "User", "consumerAmount": 1, "description": "这是证书描述信息", "licenseCheckModel": { "ipAddress": [], "macAddress": [], "cpuSerial": "", "mainBoardSerial": "" }}如果请求成功，那么最后会在 licensePath 参数设置的路径生成一个 license.lic 的文件，这个文件就是给客户部署代码的服务器许可文件。
