Java：项目license证书控制_LLLLLiSHI的博客-CSDN博客_java license

license即版权许可证。实际使用中部署给客户的项目，不能随意被二次使用。那么就需要license证书对项目做出控制。

1 pom：


<dependency>
<groupId>de.schlichtherle.truelicense</groupId>
<artifactId>truelicense-core</artifactId>
<version>1.33</version>
<scope>compile</scope>
</dependency>

2

服务端：生成license

客户端：对license做出验证

3 具体步骤

1、创建一个服务端项目和一个客户端项目
2、导入相关依赖及相关类
3、执行keytool命令，生成密钥库文件
4、调用服务端接口，以密钥库生成license文件
5、指定项目配置（如license路径），启动客户端
6、完

附1：服务端提供API

/**
* 用于生成证书文件，不能放在给客户部署的代码里
*
*/
@Api(tags = "license api")
@RestController
@RequestMapping("/license")
public class LicenseApi {
/**
* 证书生成路径
*/
@Value("${license.licensePath}")
private String licensePath;
/**
* 获取服务器硬件信息
*/
@ApiOperation(value = "获取服务器硬件信息")
@GetMapping(value = "/serverInfo")
public ResponseResult<LicenseCheckModel> getServerInfos(@RequestParam(value = "osName", required = false) String osName) {
//操作系统类型
if (StrUtil.isBlank(osName)) {
osName = System.getProperty("os.name");
}
osName = osName.toLowerCase();
AbstractServerInfos abstractServerInfos = null;
//根据不同操作系统类型选择不同的数据获取方法
if (osName.startsWith("windows")) {
abstractServerInfos = new WindowsServerInfos();
} else {
//其他服务器类型
abstractServerInfos = new LinuxServerInfos();
}
return ResponseResult.ok(abstractServerInfos.getServerInfos());
}
/**
* 生成证书
*/
@ApiOperation(value = "生成证书")
@PostMapping(value = "/generateLicense")
public ResponseResult generateLicense(@RequestBody(required = true) LicenseCreatorParam param) {
if (StrUtil.isBlank(param.getLicensePath())) {
param.setLicensePath(licensePath);
}
LicenseCreator licenseCreator = new LicenseCreator(param);
boolean result = licenseCreator.generateLicense();
if (result) {
return ResponseResult.ok("证书文件生成成功");
} else {
return ResponseResult.be("证书文件生成失败");
}
}
}

生成证书示例

{
"subject": "custom_license",
"privateAlias": "privateKey",
"keyPass": "private_password1234",
"storePass": "public_password1234",
"licensePath": "D:/temp/keytool/license.lic",
"privateKeysStorePath": "D:/temp/keytool/privateKeys.keystore",
"issuedTime": "2020-06-03 00:00:01",
"expiryTime": "2020-06-03 23:59:59",
"consumerType": "User",
"consumerAmount": 1,
"description": "这是证书描述信息",
"licenseCheckModel": {
"ipAddress": [
"1.1.1.1"
],
"macAddress": [
"A#-D5-D3-12-1F-D2"
],
"cpuSerial": "ADADADADA000239",
"mainBoardSerial": "199023140001"
}
}

附2：keytool命令

### license生成证书命令，JDK自带keytool工具
#生成：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，第一个条目为privateKey，指定条目密码为private_password1234
keytool -genkeypair -keysize 1024 -validity 1 -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：将密钥库中privateKey的条目，导出到一个名为certfile.cer的数字文件
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"
#导入：将刚刚导出的数字文件，导入为一个新的密钥库publicCerts.keystore
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"
参数释义：
alias：第一个条目别名
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）
此三命令执行完之后，会生成三个文件：privateKeys.keystore，publicCerts.keystore，certfile.cer。
privateKeys.keystore：用于服务端生产license文件
publicCerts.keystore：随客户端项目部署
certfile.cer：暂存文件，删除即可

附3：代码
