SpringBoot集成License

• 将license-device-exec.jar放到目标机器上，执行：java -jar license-device-exec.jar，生成device.json文件

• 根据device.json文件，使用工具com.yubest.gen.MainApp.main，生成公私钥及license授权文件

public class MainApp {
    public static void main(String[] args) {
        try {
            //生成公私钥对
            String subject = "mySubject";
            String pubPwd = "a123456";
            String priPwd = "a123457";
            KeyUtil.createKey(subject, pubPwd, priPwd);

            //读取客户端设备信息
            File device = new File("device.json");
            String json = Files.readAllLines(device.toPath(), Charset.forName("UTF-8")).get(0);

            //生成license
            LicenseCreatorParam param = new LicenseCreatorParam()
                    .setSubject(subject)
                    .setPubPass(pubPwd)
                    .setPriPass(priPwd)
                    .setDeviceInfo(json);
            new MyLicenseCreator()
                    .setCreatorParam(param)
                    .execute();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

• 私钥：private.key
• 公钥：public.key
• 授权文件：license.lic

• 3.1、将公钥：public.key和授权文件：license.lic放到待授权机器上
• 3.2、添加配置application.properties

license.subject=mySubject
license.storePass=a123456
license.licPath=/xxx/license.lic
license.pubKeyPath=/xxx/public.key

• 3.3、将LicenseManager注入Spring容器中

@Data
@EqualsAndHashCode(callSuper = true)
@Component
@ConfigurationProperties(prefix = "license")
public class LicenseConfig extends LicenseVerifierParam {
    @Bean
    public LicenseManager licenseManager() {
        LicenseParam param = toLicenseParam(LicenseConfig.class);
        return new MyLicenseManager(param);
    }
}

• 3.4、安装证书

@Component
@Slf4j
public class LicenseRegister implements ApplicationRunner {
    @Autowired
    private LicenseConfig config;
    @Autowired
    private LicenseManager manager;
    @Override
    public void run(ApplicationArguments args) throws Exception {
        log.info("------开始注册证书------");
        new MyLicenseVerifier().install(config.getLicPath(), manager);
        log.info("------结束注册证书------");
    }
}

• 3.5、添加接口拦截配置

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
    @Autowired
    private LicenseInterceptor licenseInterceptor;
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //添加要拦截的url
        registry.addInterceptor(licenseInterceptor)
                // 拦截的路径
                .addPathPatterns("/**");
    }
}

@Component
@Slf4j
public class LicenseInterceptor implements HandlerInterceptor {
    @Autowired
    private LicenseManager manager;
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws IOException {
        log.info("------开始校验证书------");
        try {
            new MyLicenseVerifier().verify(manager);
            return true;
        } catch (Exception e) {
            log.error("证书校验失败", e);
        }
        response.setCharacterEncoding("UTF-8");
        Map data = new HashMap<>();
        data.put("code", 1000);
        data.put("msg", "当前服务器不在授权范围内");
        response.getWriter().write(new Gson().toJson(data));
        return false;
    }
}
