Spring Boot项目中使用 TrueLicense 生成和验证License（服务器许可）
一，简介
License，即版权许可证，一般用于收费软件给付费用户提供的访问许可证明。根据应用部署位置的不同，一般可以分为以下两种情况讨论：
- 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登录的形式远程访问，因此只需要在账号登录的时候校验目标账号的有效期、访问权限等信息即可。
- 应用部署在客户的内网环境。因为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。
二， 使用 TrueLicense 生成License
1，在pom.xml中添加关键依赖
<dependency>
<groupId>de.schlichtherle.truelicensegroupId>
<artifactId>truelicense-coreartifactId>
<version>1.33version>
<scope>providedscope>
dependency>
2，校验自定义的License参数
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。
首先需要添加一个自定义的可被允许的服务器硬件信息的实体类（如果校验其他参数，可自行补充）：
package cn.zifangsky.license;
import java.io.Serializable;
import java.util.List;
/**
* 自定义需要校验的License参数
*
* @author zifangsky
* @date 2018/4/23
* @since 1.0.0
*/
public class LicenseCheckModel implements Serializable{
private static final long serialVersionUID = 8600137500316662317L;
/**
* 可被允许的IP地址
*/
private List<String> ipAddress;
/**
* 可被允许的MAC地址
*/
private List<String> macAddress;
/**
* 可被允许的CPU序列号
*/
private String cpuSerial;
/**
* 可被允许的主板序列号
*/
private String mainBoardSerial;
//省略setter和getter方法
@Override
public String toString() {
return "LicenseCheckModel{" +
"ipAddress=" + ipAddress +
", macAddress=" + macAddress +
", cpuSerial='" + cpuSerial + ''' +
", mainBoardSerial='" + mainBoardSerial + ''' +
'}';
}
}
其次，添加一个License生成类需要的参数：
package cn.zifangsky.license;
import com.fasterxml.jackson.annotation.JsonFormat;
import java.io.Serializable;
import java.util.Date;
/**
* License生成类需要的参数
*
* @author zifangsky
* @date 2018/4/19
* @since 1.0.0
*/
public class LicenseCreatorParam implements Serializable {
private static final long serialVersionUID = -7793154252684580872L;
/**
* 证书subject
*/
private String subject;
/**
* 密钥别称
*/
private String privateAlias;
/**
* 密钥密码（需要妥善保管，不能让使用者知道）
*/
private String keyPass;
/**
* 访问秘钥库的密码
*/
private String storePass;
/**
* 证书生成路径
*/
private String licensePath;
/**
* 密钥库存储路径
*/
private String privateKeysStorePath;
/**
* 证书生效时间
*/
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private Date issuedTime = new Date();
/**
* 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 = "user";
/**
* 用户数量
*/
private Integer consumerAmount = 1;
/**
* 描述信息
*/
private String description = "";
/**
* 额外的服务器硬件校验信息
*/
private LicenseCheckModel licenseCheckModel;
//省略setter和getter方法
@Override
public String toString() {
return "LicenseCreatorParam{" +
"subject='" + subject + ''' +
", privateAlias='" + privateAlias + ''' +
", keyPass='" + keyPass + ''' +
", storePass='" + storePass + ''' +
", licensePath='" + licensePath + ''' +
", privateKeysStorePath='" + privateKeysStorePath + ''' +
", issuedTime=" + issuedTime +
", expiryTime=" + expiryTime +
", consumerType='" + consumerType + ''' +
", consumerAmount=" + consumerAmount +
", description='" + description + ''' +
", licenseCheckModel=" + licenseCheckModel +
'}';
}
}

@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;
}
}
三，使用JDK自带的 keytool 工具生成公私钥证书库
假如我们设置公钥库密码为：public_password1234，私钥库密码为：private_password1234，则生成命令如下：
#生成命令
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"
上述命令执行完成之后，会在当前路径下生成三个文件，分别是：privateKeys.keystore、publicCerts.keystore、certfile.cer。其中文件certfile.cer不再需要可以删除，文件privateKeys.keystore用于当前的 ServerDemo 项目给客户生成license文件，而文件publicCerts.keystore则随应用代码部署到客户服务器，用户解密license文件并校验其许可信息。
四，为客户生成license文件
将 ServerDemo 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）：
然后生成license文件：
请求时需要在Header中添加一个 Content-Type ，其值为：application/json;charset=UTF-8。参数示例如下：
{
"subject": "license_demo",
"privateAlias": "privateKey",
"keyPass": "private_password1234",
"storePass": "public_password1234",
"licensePath": "C:/Users/zifangsky/Desktop/license_demo/license.lic",
"privateKeysStorePath": "C:/Users/zifangsky/Desktop/license_demo/privateKeys.keystore",
"issuedTime": "2018-07-10 00:00:01",
"expiryTime": "2019-12-31 23:59:59",
"consumerType": "User",
"consumerAmount": 1,
"description": "这是证书描述信息",
"licenseCheckModel": {
"ipAddress": ["192.168.245.1", "10.0.5.22"],
"macAddress": ["00-50-56-C0-00-01", "50-7B-9D-F9-18-41"],
"cpuSerial": "BFEBFBFF000406E3",
"mainBoardSerial": "L1HF65E00X9"
}
}
如果请求成功，那么最后会在 licensePath 参数设置的路径生成一个license.lic的文件，这个文件就是给客户部署代码的服务器许可文件。
五，给客户部署的应用中添加License校验
1，添加License校验类需要的参数
package cn.zifangsky.license;
/**
* License校验类需要的参数
*
* @author zifangsky
* @date 2018/4/20
* @since 1.0.0
*/
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;
public LicenseVerifyParam() {
}
public LicenseVerifyParam(String subject, String publicAlias, String storePass, String licensePath, String publicKeysStorePath) {
this.subject = subject;
this.publicAlias = publicAlias;
this.storePass = storePass;
this.licensePath = licensePath;
this.publicKeysStorePath = publicKeysStorePath;
}
//省略setter和getter方法
@Override
public String toString() {
return "LicenseVerifyParam{" +
"subject='" + subject + ''' +
", publicAlias='" + publicAlias + ''' +
", storePass='" + storePass + ''' +
", licensePath='" + licensePath + ''' +
", publicKeysStorePath='" + publicKeysStorePath + ''' +
'}';
}
}
然后再添加License校验类：
package cn.zifangsky.license;
import de.schlichtherle.license.*;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import java.io.File;
import java.text.DateFormat;
import java.text.MessageFormat;
import java.text.SimpleDateFormat;
import java.util.prefs.Preferences;
/**
* License校验类
*
* @author zifangsky
* @date 2018/4/20
* @since 1.0.0
*/
public class LicenseVerify {
private static Logger logger = LogManager.getLogger(LicenseVerify.class);
/**
* 安装License证书
* @author zifangsky
* @date 2018/4/20 16:26
* @since 1.0.0
*/
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()));
logger.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){
logger.error("证书安装失败！",e);
}
return result;
}
/**
* 校验License证书
* @author zifangsky
* @date 2018/4/20 16:26
* @since 1.0.0
* @return boolean
*/
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();
// System.out.println(licenseContent.getSubject());
logger.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){
logger.error("证书校验失败！",e);
return false;
}
}
/**
* 初始化证书生成参数
* @author zifangsky
* @date 2018/4/20 10:56
* @since 1.0.0
* @param param License校验类需要的参数
* @return de.schlichtherle.license.LicenseParam
*/
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);
}
}
2，添加Listener，用于在项目启动的时候安装License证书
package cn.zifangsky.license;
import org.apache.commons.lang3.StringUtils;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
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;
/**
* 在项目启动时安装证书
*
* @author zifangsky
* @date 2018/4/24
* @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 ++++++++");
}
}
}
}
注：上面代码使用参数信息如下所示：
#License相关配置
license.subject=license_demo
license.publicAlias=publicCert
license.storePass=public_password1234
license.licensePath=C:/Users/zifangsky/Desktop/license_demo/license.lic
license.publicKeysStorePath=C:/Users/zifangsky/Desktop/license_demo/publicCerts.keystore
3，添加拦截器，用于在登录的时候校验License证书
package cn.zifangsky.license;
import com.alibaba.fastjson.JSON;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;
/**
* LicenseCheckInterceptor
*
* @author zifangsky
* @date 2018/4/25
* @since 1.0.0
*/
public class LicenseCheckInterceptor extends HandlerInterceptorAdapter{
private static Logger logger = LogManager.getLogger(LicenseCheckInterceptor.class);
@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");
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;
}
}
}
4，添加登录页面并测试

<head>
<meta content="text/html;charset=UTF-8"/>
<meta http-equiv="X-UA-Compatible" content="IE=edge"/>

启动项目，可以发现之前生成的license证书可以正常使用：
这时访问 http://127.0.0.1:7080/login ，可以正常登录：
重新生成license证书，并设置很短的有效期。
重新启动ClientDemo，并再次登录，可以发现爆以下提示信息：
至此，关于使用 TrueLicense 生成和验证License就结束了
转自大佬：Spring Boot项目中使用 TrueLicense 生成和验证License（服务器许可）
