SpringBoot项目License证书生成与验证(TrueLicense) 【记录】
在非开源产品、商业软件、收费软件等系统的使用上,需要考虑系统的使用版权问题,不能随便一个人拿去在任何环境都能用。应用部署一般分为两种情况:
- 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扽了给的形式远程访问。只需要在账号登录时,校验目标账号的有效期、访问权限等信息。
- 应用部署在客户的内网环境中,开发者没有办法控制客户的网络环境以及不能保证应用所在服务器能够访问外网(不能走网上认证)。这种情况下通常的做法就是使用服务器许可文件。在应用启动的时候加载证书,然后在登录或者其它关键操作的地方校验证书的有效性。
一、License介绍
TrueLicense 是一个开源的证书管理引擎。采用非对称加密方式对 License源数据 进行预处理,防止伪造License。
软件许可(License)证书可以在软件产品交付的时候,对其使用时间以及使用范围进行授权。当用户申请(购买)改变使用时间和使用范围的时候,授权方可以为用户生成一个新的license替换原来的license即可,从而避免了修改源码、改动部署等繁琐操作。
- 授权机制原理
- 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的信息(使用截止日期、MAC地址/机器码、模块数据 等)的license证书进行数字签名。
- 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。
- License 运行流程:
二、KeyTool生成密钥对
使用 JDK 中的 KeyTool 工具生成密钥对。
在cmd.exe中运行生成密钥对的命令:
- 生成私钥库:
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”
参数 | 释义 |
---|---|
alias | 私钥别名 |
validity | 私钥的有效时间天数 |
keystore | 指定密钥库文件的名称 |
storepass | 指定密钥库密码(获取keystore信息锁需要的密码) |
keypass | 指定别名条目对应的密码(私钥密码) |
在当前目录下,生成一个名为privateKeys.keystore的密钥库,同时指定密钥库密码为public_password1234,第一个条目(秘钥)为privateKey,指定条目密码为private_password1234。
- 将私钥库内的公钥导出到文件中
keytool -exportcert -alias “privateKey” -keystore “privateKeys.keystore” -storepass “public_password1234” -file “certfile.cer”
参数 | 释义 |
---|---|
alias | 私钥别名 |
validity | 私钥的有效时间天数 |
keystore | 指定密钥库文件的名称 |
storepass | 指定密钥库密码(获取keystore信息锁需要的密码) |
keypass | 指定别名条目对应的密码(私钥密码) |
file | 证书名称 |
将“privateKey”秘钥的公钥(即主体信息,包括公钥,不包括私钥,可公开)导出到名称为certfile.cer文件中!
- 将该证书文件导入到公钥库中
keytool -import -alias “publicCert” -file “certfile.cer” -keystore “publicCerts.keystore” -storepass “public_password1234”
将上一步导出的certfile.cer文件中的公钥导入到公钥库!
在执行完以上命令后就会在当前文件夹下生成3个文件:privateKeys.keystore、publicCerts.keystore、certfile.cer
- certfile.cer是暂存文件,删除即可。
- privateKeys.keystore :服务端用来为用户生成License文件
- publicCerts.keystore :随客户端项目部署到客户服务端,用其解密License文件并校验其许可信息。
三、springboot整合TrueLicense
改步骤的目的是,在服务端生成授权文件 License!
3.1 构建基础模型数据
- 引入TrueLisence
<!-- Licence证书生成依赖 -->
<dependency>
<groupId>de.schlichtherle.truelicense</groupId>
<artifactId>truelicense-core</artifactId>
<version>1.33</version>
</dependency>
- 创建License证书自定义校验数据模型类
package com.zdsf.u8cloudmanagementproject.core.license;
import lombok.Data;
import java.io.Serializable;
import java.util.List;
/**
* @ClassName : LicenseCheckModel
* @Description : 自定义需要校验的参数
* @Author : AD
*/
@Data
public class LicenseCheckModel implements Serializable {
private static final long serialVersionUID = -2314678441082223148L;
/**
* 可被允许IP地址白名单
* */
private List<String> ipAddress;
/**
* 可被允许的MAC地址白名单(网络设备接口的物理地址,通常固化在网卡(Network Interface Card,NIC)的EEPROM(电可擦可编程只读存储器)中,具有全球唯一性。)
* */
private List<String> macAddress;
/**
* 可允许的CPU序列号
* */
private String cpuSerial;
/**
* 可允许的主板序列号(硬件序列化?)
* */
private String mainBoardSerial;
}
- 创建License证书标准校验参数模型类
package com.zdsf.u8cloudmanagementproject.core.license;
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;
import java.io.Serializable;
import java.util.Date;
/**

@Data
public class LicenseCreatorParam implements Serializable {
private static final long serialVersionUID = 2832129012982731724L;
/**

private Date issuedTime = new Date();
/**

private String consumerType ="user";
/**

private Integer consumerAmount = 1;
/**
* 描述信息
* */
private String description = "";
/**
* 额外的服务器硬件校验信息(机器码)
* */
private LicenseCheckModel licenseCheckModel;
}
3.2 客户服务器数据获取
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 机器码 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。
获取客户服务器基本信息,比如:IP、Mac地址、CPU序列号、主板序列号等!
- 创建获取客户端服务器相关机器码的抽象类
这里采用抽象类的原因是,客户端在Linux 和 windows 不同类型服务器上部署项目时,在获取相关机器码的方式上会有所差别,所以这里才有抽象类来封装,具体实现就交给下游的各系统类型的实现来分别实现各个方法!
注:这里使用了模板方法模式,将不变部分的算法封装到抽象类,而基本方法的具体实现则由子类来实现。

3.3 其它Custom定制类的创建
3.3.1 公私钥存储相关类定义
通过继承AbstractKeyStoreParam抽象类,重新其中的 getStream方法,达到将公钥、私钥存放到其它磁盘位置,而不是项目中!
package com.zdsf.u8cloudmanagementproject.core.license;
import de.schlichtherle.license.AbstractKeyStoreParam;
import java.io.*;
/**
* @ClassName : CustomKeyStoreParam
* @Description : 自定义KeyStoreParam,用于将公私钥存储文件存放到其它磁盘位置,而不是存放在项目中
* @Author : AD
*/
public class CustomKeyStoreParam extends AbstractKeyStoreParam {
/**
* 公钥 / 私钥 在磁盘上的存储路径
* */
private String storePath;
private String alias;
private String storePwd;
private String keyPwd;
public CustomKeyStoreParam(Class aClass, String resource,String alias,String storePwd,String keyPwd) {
super(aClass, resource);
this.storePath = resource;
this.alias = alias;
this.storePwd = storePwd;
this.keyPwd = keyPwd;
}
@Override
public String getAlias() {
return alias;
}
@Override
public String getStorePwd() {
return storePwd;
}
@Override
public String getKeyPwd() {
return keyPwd;
}
@Override
public InputStream getStream() throws IOException {
final InputStream in = new FileInputStream(new File(storePath));
if (null == in){
throw new FileNotFoundException(storePath);
}
return in;
}
}
3.3.2 自定义License管理类
创建CustomLicenseManager 管理类,该类继承LicenseManager 类,用来增加我门额外信息的验证工作( TrueLicense默认只给我们验证了时间 )。所以这里需要根据自己的需求在validate()里面增加额外的验证项!
在父类 LicenseManager类中主要的几个方法如下:
- create 创建证书
重写该方法,因为 LicenseManager类中默认的创建证书方法中,只含有的参数为:有效期、用户类型、用户数量等数据,但是不包含自己拓展的相关的数据(机器码)等。
- install 安装证书
- verify 验证证书
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。

3.3.4 服务端控制层
这里需要在项目中的application.properties配置文件中确定一个证书生成路径@Value("${license.licensePath}")
,
同时还需要将之前通过 KeyTool生成的私钥复制到该目录下。

- 获取部署服务器机器码数据接口测试
- generateLicense生成证书方法示例参数:
{
“subject”: “license_demo”,
“privateAlias”: “privateKey”,
“keyPass”: “private_password1234”,
“storePass”: “public_password1234”,
“licensePath”: “E:/LicenseDemo/license.lic”,
“privateKeysStorePath”: “E:/LicenseDemo/privateKeys.keystore”,
“issuedTime”: “2022-04-26 14:48:12”,
“expiryTime”: “2022-08-22 00:00:00”,
“consumerType”: “User”,
“consumerAmount”: 1,
“description”: “这是证书描述信息”,
“licenseCheckModel”: {
“ipAddress”: [
“192.168.3.57”
],
“macAddress”: [

],
“cpuSerial”: “BFEBFBFF000806EA”,
“mainBoardSerial”: “PM01I01911000743”
}
}
生成了License证书:
将 客户端 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)。
- License 申请流程
- 找回License
四、客户端部署应用添加License校验
其中获取客户服务器的基本信息【AbstractServerInfos.class】,获取客户Linux服务器的基本信息【LinuxServerInfos.class】,获取客户Windows服务器的基本信息【WindowsServerInfos.class】,自定义的可被允许的服务器硬件信息的实体类【LicenseCheckModel.class】,自定义LicenseManager【CustomLicenseManager.class】,自定义KeyStoreParam【CustomKeyStoreParam.class】均与服务端代码一致;
新增的内容如下:
4.1 证书校验相关类
- 证书校验参数类

4.2 拦截器相关配置
- 证书验证拦截器
package com.zdsf.u8cloudmanagementproject.core.license;
import com.alibaba.fastjson2.JSONObject;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* @ClassName : LoginInterceptor
* @Description : 拦截器,请求拦截器 拦截相关请求验证证书
* @Author : AD
*/
@Component
public class LicenseCheckInterceptor implements HandlerInterceptor {
@Override
public 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");
JSONObject obj = new JSONObject();
obj.put("errcode", "0319");
obj.put("errmsg", "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().print(obj);
response.getWriter().flush();
return false;
}
}
}
- 拦截器配置类
package com.zdsf.u8cloudmanagementproject.config;
import com.zdsf.u8cloudmanagementproject.core.license.LicenseCheckInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
* @ClassName : WebMvcConfig
* @Description : 注册 拦截器配置
* @Author : AD
*/
@Configuration
public class WebMvcConfig implements WebMvcConfigurer{
@Override
public void addInterceptors(InterceptorRegistry registration){
registration.addInterceptor(new LicenseCheckInterceptor()).addPathPatterns("/check/**");
}
}
4.3 其它配置
- application.properties 配置文件内容示例
# license.licensePath = E:/LicenseDemo
#License相关配置
license.subject=license_demo
license.publicAlias=publicCert
license.storePass=public_password1234
license.licensePath=E:/LicenseDemo/license.lic
license.publicKeysStorePath=E:/LicenseDemo/publicCerts.keystore
license.uploadPath=E:/LicenseDemo/
- 证书安装监听器 (项目启动时进行证书的安装操作)
package com.zdsf.u8cloudmanagementproject.core.license;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.stereotype.Component;
/**
* @ClassName : LicenseCheckListener
* @Description : 用于在项目启动的时候安装License证书
* @Author : AD
*/
@Component
public class LicenseCheckListener implements ApplicationListener<ContextRefreshedEvent> {
private static Logger logger = LoggerFactory.getLogger(LicenseCheckListener.class);
/**
* 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("${license.storePass}")
private String storePass;
/**
* 证书生成路径
*/
@Value("${license.licensePath}")
private String licensePath;
/**
* 密钥库存储路径
*/
@Value("${license.publicKeysStorePath}")
private String publicKeysStorePath;
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
//root application context 没有parent
ApplicationContext context = event.getApplicationContext().getParent();
if(context == null){
if(StringUtils.isNotBlank(licensePath)){
logger.info("++++++++ 开始安装证书 ++++++++");
LicenseVerifyParam param = new LicenseVerifyParam();
param.setSubject(subject);
param.setPublicAlias(publicAlias);
param.setStorePass(storePass);
param.setLicensePath(licensePath);
param.setPublicKeysStorePath(publicKeysStorePath);
LicenseVerify licenseVerify = new LicenseVerify();
//安装证书
licenseVerify.install(param);
logger.info("++++++++ 证书安装结束 ++++++++");
}
}
}
}
- 测试访问地址拦截controller
package com.licenseDemo.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
import java.util.Map;
/**
* @ClassName : LoginController
* @Description : 模拟登录check检测证书
* @Author : AD
*/
@RestController
@RequestMapping("/check")
public class LoginController {
@PostMapping("/login")
public Map<String, Object> check(String username, String password) {
Map<String, Object> result = new HashMap<>();
//模拟登录check
result.put("success", true);
result.put("message", "登录成功");
result.put("data", "证书校验通过");
return result;
}
@GetMapping("/getLogin")
public Map<String, Object> check2(String username) {
System.out.println("username = " + username);
Map<String, Object> result = new HashMap<>();
//模拟登录check
result.put("success", true);
result.put("message", "登录成功");
result.put("data", "证书校验通过");
return result;
}
}
4.4 测试客户端
- 启动客户端,生成证书:
- 调用接口验证了证书
