Springboot 添加License 以及生成证书和证书验证
在Spring Boot中添加License并生成证书,可以使用Java代码手动完成,也可以使用专门的库,如Aspose。以下是一个简单的例子,展示如何生成一个证书并将其添加到License中。
首先,添加Aspose的依赖到你的pom.xml
文件中:
<dependency>
<groupId>com.aspose</groupId>
<artifactId>aspose-license</artifactId>
<version>1.0</version>
</dependency>
然后,使用Java代码生成证书并添加到License中:
import com.aspose.license.License;
import com.aspose.license.Manifest;
import com.aspose.license.Pdf;
import java.io.FileOutputStream;
import java.security.KeyPair;
import java.security.KeyPairGenerator;
import java.security.NoSuchAlgorithmException;
import java.security.PrivateKey;
import java.security.PublicKey;
import java.util.Properties;
public class LicenseGenerator {
public static void main(String[] args) throws Exception {
// 生成证书
KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
keyPairGenerator.initialize(2048);
KeyPair keyPair = keyPairGenerator.generateKeyPair();
PublicKey publicKey = keyPair.getPublic();
PrivateKey privateKey = keyPair.getPrivate();
// 保存证书到文件
FileOutputStream publicKeyOutputStream = new FileOutputStream("public.key");
publicKeyOutputStream.write(publicKey.getEncoded());
publicKeyOutputStream.close();
FileOutputStream privateKeyOutputStream = new FileOutputStream("private.key");
privateKeyOutputStream.write(privateKey.getEncoded());
privateKeyOutputStream.close();
// 创建License
Properties properties = new Properties();
properties.setProperty("subject", "Aspose Test Subject");
properties.setProperty("feature", "Aspose Test Feature");
properties.setProperty("licensee", "Aspose Test Licensee");
properties.setProperty("issuer", "Aspose Test Issuer");
properties.setProperty("issued", "2023-01-01");
properties.setProperty("validity", "2099-01-01");
properties.setProperty("publicExponent", "10001");
properties.setProperty("privateExponent", "c3f1ca2153257f02949a0493d06ed8545ff4c63765b49777f1e624a594b225b2");
License license = new License();
license.setManifest(new Manifest(properties));
license.setPdf(new Pdf("license.pdf", publicKey));
// 保存License到文件
license.save("license.bin");
}
}
在这个例子中,我们首先生成了一对非对称加密的证书,并将公钥保存到文件中。然后,我们创建了一个License对象,并设置了相关的属性,将私钥和公
