基于springboot项目License的生成和验证

1 .使用JDK自带的 keytool 工具生成公私钥证书库,私钥用于生成License文件,公钥用于验证License文件,我这里只是给一个时间验证,证书的过期时间

生成证书接口

Controller层

@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; } public boolean generateLicense(){ try { LicenseManager licenseManager = new CustomLicenseManager(initLicenseParam()); LicenseContent licenseContent = initLicenseContent(); licenseManager.store(licenseContent,new File(param.getLicensePath())); return true; }catch (Exception e){ logger.error(MessageFormat.format("证书生成失败：{0}",param),e); return false; } }

验证License证书

/** * 在项目启动时安装证书 * * @since 1.0.0 */ @Component public class LicenseCheckListener implements ApplicationListener<ContextRefreshedEvent> { private static Logger logger = LogManager.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 ++++++++"); } } } @Scheduled(cron = "0 0 0 * * ?") public void aVoid( ){ 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 ++++++++"); } } }
