SpringBoot实现证书License的授权和验证
SpringBoot使用TrueLicense实现证书License的授权和验证
·
1、首先需要生成密钥对，常用的方法为JDK自带的KeyTool工具生成；
2、创建licenseServer项目，使用TrueLicense和私钥生成License许可文件，注意服务端代码和私钥需要我们自己留存；
3、使用公钥和License许可文件为客户端代码添加License校验
KeyTool生成密钥对
密钥对命令
cmd.exe下运行下列命令
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"
# 导出命令
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"
#导入命令
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"命令执行完之后，会生成三个文件：privateKeys.keystore，publicCerts.keystore，certfile.cer
其中certfile.cer是暂存文件，删除即可；
privateKeys.keystore：用于服务端生成license文件
publicCerts.key
参数释义
| 参数 | 释义 |
| alias | 别名 |
| validity | 证书有效期，单位：天 |
| keystore | 指定密钥库名称 |
| storepass | 指定密钥库密码 |
| keypass | 指定别名对应密码（私钥密码） |

licenseContent.setConsumerAmount(param.getConsumerAmount());
licenseContent.setInfo(param.getDescription());
//扩展校验服务器硬件信息
licenseContent.setExtra(param.getLicenseCheckModel());
return licenseContent;
}
}添加一个生成证书的Controller，对外提供了两个RESTful接口，分别是「获取服务器硬件信息」和「生成证书」

@RequestMapping("/license")
public class LicenseCreatorController {
/**

@Value("${license.licensePath}")

}
osName = osName.toLowerCase();

}
/**

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;
}
}获取服务器硬件信息：
生成证书：
示例参数如下所示：
{
"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"
}
}运行完生成证书接口后即可在 E:/LicenseDemo/目录下看到【license.lic】证书：
客户端代码实现认证
这里使用我本地已有项目的客户端代码，不再单独写个demo了，总体思路是：
首先将服务端生成的【license.lic】证书文件与keytool生成的公钥【publicCerts.keystore】放到客户端代码指定的路径下；
然后在启动客户端代码的时候安装证书；
最后再拦截需要验证证书的接口的拦截器里添加License校验，我这里的需求是所有访问的接口都要拦截。

* 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 ++++++++");
}
}
}
}上述安装证书的类要与服务端生成证书的类要在同一个包路径下
尤其是LicenseCheckModel类需要在同一个包路径下，防止XML反序列化失败，我的都是在【com.bw.license】路径下。
拦截器校验license证书
@Component
public class LoginInterceptor 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;
}
}
}
