一、License介绍
License也就是版权许可证书,一般用于收费软件给付费用户提供的访问许可证明
应用场景
应用部署在客户的内网环境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
License授权原理
使用开源的证书管理引擎TrueLicense
生成密钥对,使用Keytool生成公私钥证书库
授权者保留私钥,使用私钥和使用日期生成证书license
公钥与生成的证书给使用者(放在验证的代码中使用),验证证书license是否在有效期内
二、授权者生成密钥对
需要关注以及修改的参数:storepass(私钥库的密码)、keypass(私钥的密码)其他参数使用默认值即可,validity(私钥的有效期)设置十年就可以,因为以后会通过私钥和证书有效期生成证书license
## 1. 生成私匙库> 基于 Spring Cloud Alibaba + Gateway + Nacos + RocketMQ + Vue & Element 实现的后台管理系统 + 用户小程序,支持 RBAC 动态权限、多租户、数据权限、工作流、三方登录、支付、短信、商城等功能

> * 项目地址:<https://github.com/YunaiV/yudao-cloud>
> * 视频教程:<https://doc.iocoder.cn/video/># validity:私钥的有效期(单位:天)
# alias:私钥别称
# keystore: 私钥库文件名称(生成在当前目录)
# storepass:私钥库的密码(获取keystore信息所需的密码)
# keypass:私钥的密码
# dname 证书个人信息
# CN 为你的姓名
# OU 为你的组织单位名称
# O 为你的组织名称
# L 为你所在的城市名称
# ST 为你所在的省份名称
# C 为你的国家名称 或 区号
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: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 "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(生成在当前目录)
# storepass:私钥库的密码
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"
上述命令执行完成后会在当前目录生成三个文件:
certfile.cer 认证证书文件,已经没用了,可以删除
privateKeys.keystore 私钥文件,自己保存,以后用于生成license.lic证书
publicKeys.keystore 公钥文件,以后会和license.lic证书一起放到使用者项目里
三、授权者生成license.lic证书
3.1、 配置pom.xml
<!-- License -->
<dependency><groupId>de.schlichtherle.truelicense</groupId><artifactId>truelicense-core</artifactId><version>1.33</version>
</dependency>
3.2 、License生成类
import de.schlichtherle.license.*;
import lombok.extern.slf4j.Slf4j;
import javax.security.auth.x500.X500Principal;
import java.io.File;
import java.io.IOException;
import java.time.LocalDateTime;

import java.util.Date;
import java.util.prefs.Preferences;@Slf4j
public class LicenseCreator {private final static X500Principal DEFAULT_HOLDER_AND_ISSUER = new X500Principal("CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN");/*** @description main方法生成license文件* @author xuchang* @date 2024/3/4 15:51:14*/public static void main(String[] args) throws IOException {LicenseCreatorParam param = new LicenseCreatorParam();// 证书主题param.setSubject("license");// 密钥别称param.setPrivateAlias("privateKey");// 私钥密码param.setKeyPass("private_password1234");// 私钥库的密码param.setStorePass("public_password1234");// 证书生成路径param.setLicensePath("/Users/xuchang/Documents/license/license.lic");// 私钥存储路径param.setPrivateKeysStorePath("/Users/xuchang/Documents/license/privateKeys.keystore");// 证书生成时间-当前时间param.setIssuedTime(new Date());LocalDateTime localDateTime = LocalDateTime.of(2024, 12, 31, 23, 59, 59);Date date = Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());// 证书过期时间-2024年12月31日23:59:59param.setExpiryTime(date);// 用户类型param.setConsumerType("user");// 用户数量param.setConsumerAmount(1);// 证书描述param.setDescription("证书描述信息");// 生成证书LicenseCreator licenseCreator = new LicenseCreator();licenseCreator.generateLicense(param);}// 生成License证书public void generateLicense(LicenseCreatorParam param) {try {LicenseManager licenseManager = new LicenseManager(initLicenseParam(param));LicenseContent licenseContent = initLicenseContent(param);licenseManager.store(licenseContent, new File(param.getLicensePath()));} catch (Exception e) {log.error("证书生成失败", e);}}// 初始化证书生成参数private static LicenseParam initLicenseParam(LicenseCreatorParam param) {Preferences preferences = Preferences.userNodeForPackage(LicenseCreator.class);// 设置对证书内容加密的秘钥CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());// 自定义KeyStoreParamKeyStoreParam privateStoreParam = new CustomKeyStoreParam(LicenseCreator.class, param.getPrivateKeysStorePath(), param.getPrivateAlias(), param.getStorePass(), param.getKeyPass());// 组织License参数return new DefaultLicenseParam(param.getSubject(), preferences, privateStoreParam, cipherParam);}// 设置证书生成正文信息private static LicenseContent initLicenseContent(LicenseCreatorParam param) {LicenseContent licenseContent = new LicenseContent();licenseContent.setHolder(DEFAULT_HOLDER_AND_ISSUER);licenseContent.setIssuer(DEFAULT_HOLDER_AND_ISSUER);licenseContent.setSubject(param.getSubject());licenseContent.setIssued(param.getIssuedTime());licenseContent.setNotBefore(param.getIssuedTime());licenseContent.setNotAfter(param.getExpiryTime());licenseContent.setConsumerType(param.getConsumerType());licenseContent.setConsumerAmount(param.getConsumerAmount());licenseContent.setInfo(param.getDescription());return licenseContent;}
}
3.3 、License生成类需要的参数类
@Data
public class LicenseCreatorParam {/*** 证书subject*/private String subject;/*** 密钥别称*/private String privateAlias;/*** 公钥密码(需要妥善保管,不能让使用者知道)*/private String keyPass;/*** 私钥库的密码*/private String storePass;/*** 证书生成路径*/private String licensePath;/*** 私钥存储路径*/private String privateKeysStorePath;/*** 证书生效时间*/@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")private Date issuedTime;/*** 证书失效时间*/@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")private Date expiryTime;/*** 用户类型*/private String consumerType;/*** 用户数量*/private Integer consumerAmount;/*** 描述信息*/private String description;
}
3.4、自定义KeyStoreParam
public class CustomKeyStoreParam extends AbstractKeyStoreParam {private final String storePath;private final String alias;private final String storePwd;private final String keyPwd;public CustomKeyStoreParam(Class clazz, String resource, String alias, String storePwd, String keyPwd) {super(clazz, resource);this.storePath = resource;this.alias = alias;this.storePwd = storePwd;this.keyPwd = keyPwd;}@Overridepublic String getAlias() {return alias;}@Overridepublic String getStorePwd() {return storePwd;}@Overridepublic String getKeyPwd() {return keyPwd;}@Overridepublic InputStream getStream() throws IOException {return Files.newInputStream(Paths.get(storePath));}
}
3.5、main方法生成license.lic注意事项
以上都是授权者需要做的,下面说下使用者需要的配置
四、使用者配置
4.1、配置pom.xml
<!-- License -->
<dependency><groupId>de.schlichtherle.truelicense</groupId><artifactId>truelicense-core</artifactId><version>1.33</version>
</dependency>
4.2、License校验类
@Slf4j
public class LicenseVerify {// 安装License证书public synchronized LicenseContent install(LicenseVerifyParam param) {LicenseContent result = null;DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");// 1. 安装证书try {LicenseManager licenseManager = LicenseManagerHolder.getInstance(initLicenseParam(param));licenseManager.uninstall();result = licenseManager.install(new File(param.getLicensePath()));log.info(MessageFormat.format("证书安装成功,证书有效期:{0} - {1}", format.format(result.getNotBefore()), format.format(result.getNotAfter())));} catch (Exception e) {log.error("证书安装失败: {}", e.getMessage());}return result;}// 校验License证书public boolean verify() {LicenseManager licenseManager = LicenseManagerHolder.getInstance(null);DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");// 2. 校验证书try {LicenseContent licenseContent = licenseManager.verify();log.info(MessageFormat.format("证书校验通过,证书有效期:{0} - {1}", format.format(licenseContent.getNotBefore()), format.format(licenseContent.getNotAfter())));return true;} catch (Exception e) {log.error("证书校验失败: {}", e.getMessage());return false;}}// 初始化证书生成参数private LicenseParam initLicenseParam(LicenseVerifyParam param) {Preferences preferences = Preferences.userNodeForPackage(LicenseVerify.class);CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());KeyStoreParam publicStoreParam = new CustomKeyStoreParam(LicenseVerify.class, param.getPublicKeysStorePath(), param.getPublicAlias(), param.getStorePass(), null);return new DefaultLicenseParam(param.getSubject(), preferences, publicStoreParam, cipherParam);}
}
4.3、License校验类需要的参数
@Data
public class LicenseVerifyParam {/*** 证书subject*/private String subject;/*** 公钥别称*/private String publicAlias;/*** 访问公钥库的密码*/private String storePass;/*** 证书生成路径*/private String licensePath;/*** 密钥库存储路径*/private String publicKeysStorePath;
}
4.4、自定义KeyStoreParam(与授权者一样)
public class CustomKeyStoreParam extends AbstractKeyStoreParam {private final String storePath;private final String alias;private final String storePwd;private final String keyPwd;public CustomKeyStoreParam(Class clazz, String resource,String alias,String storePwd,String keyPwd) {super(clazz, resource);this.storePath = resource;this.alias = alias;this.storePwd = storePwd;this.keyPwd = keyPwd;}@Overridepublic String getAlias() {return alias;}@Overridepublic String getStorePwd() {return storePwd;}@Overridepublic String getKeyPwd() {return keyPwd;}@Overridepublic InputStream getStream() throws IOException {return Files.newInputStream(Paths.get(storePath));}
}
4.5、LicenseManager的单例
public class LicenseManagerHolder {private static volatile LicenseManager LICENSE_MANAGER;public static LicenseManager getInstance(LicenseParam param){if(LICENSE_MANAGER == null){synchronized (LicenseManagerHolder.class){if(LICENSE_MANAGER == null){LICENSE_MANAGER = new LicenseManager(param);}}}return LICENSE_MANAGER;}
}
五、项目启动时安装证书
application.poperties配置
#License配置
# 与创建license.lic设置的值一样
license.subject=license
# 与生成密钥对的公钥别称一样
license.publicAlias=publicCert
# 私钥库的密码
license.storePass=public_password1234
license.lic证书和publicCerts.keystore放入resources资源目录下
springboot项目启动后执行操作
@Slf4j
@Component
public class LicenseCheckRunner implements ApplicationRunner {/*** 证书subject*/@Value("${license.subject}")private String subject;/*** 公钥别称*/@Value("${license.publicAlias}")private String publicAlias;/*** 访问公钥库的密码*/@Value("${license.storePass}")private String storePass;@Overridepublic void run(ApplicationArguments args) throws Exception {log.info("++++++++ 开始安装证书 ++++++++");LicenseVerifyParam param = new LicenseVerifyParam();param.setSubject(subject);param.setPublicAlias(publicAlias);param.setStorePass(storePass);// 相对路径resources资源目录String resourcePath = getClass().getClassLoader().getResource("").getPath();// 证书地址param.setLicensePath(resourcePath + "license.lic");// 公钥地址param.setPublicKeysStorePath(resourcePath + "publicCerts.keystore");// 安装证书LicenseVerify licenseVerify = new LicenseVerify();licenseVerify.install(param);log.info("++++++++ 证书安装结束 ++++++++");}
}
如果想要当前配置作为公共类,对于多个微服务,只想要一个服务resources/license下配置证书和公钥
获取公共服务里证书和公钥的输入流,然后拷贝到当前服务下
启动安装成功
六、设置拦截器
配置拦截器
@Slf4j
public class LicenseCheckInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {LicenseVerify licenseVerify = new LicenseVerify();// 校验证书是否有效boolean verifyResult = licenseVerify.verify();if (verifyResult) {return true;} else {response.setCharacterEncoding("utf-8");Map<String, String> result = new HashMap<>(1);result.put("result", "您的证书无效,请核查服务器是否取得授权或重新申请证书!");response.getWriter().write(JSON.toJSONString(result));return false;}}
}
注册拦截器
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(new LicenseCheckInterceptor());}
}
证书有效期内请求接口
证书过期请求接口
