Java字符串加密HMAC-SHA1密钥，转换成Base64编码

新建一个maven测试项目，直接把代码复制过去就行，把data和secretKey的值替换成想加密的值。

package test;import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import org.apache.commons.codec.binary.Base64;public class testP {public static String hmacSha1ToBase64(String data, String secretKey) {try {// 创建一个HMAC-SHA1密钥SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes(), "HmacSHA1");// 获得一个Mac对象Mac mac = Mac.getInstance("HmacSHA1");mac.init(signingKey);// 计算HMAC值byte[] rawHmac = mac.doFinal(data.getBytes());// 将HMAC值转换成Base64编码return Base64.encodeBase64String(rawHmac);} catch (InvalidKeyException | NoSuchAlgorithmException e) {throw new RuntimeException("获取失败：", e);}}public static void main(String[] args) {String data = "值1";String secretKey = "值2";String encryptedData = hmacSha1ToBase64(data, secretKey);System.out.println("HMAC-SHA1加Base64输出成功: " + encryptedData);}
}

如果复制过去import org.apache.commons.codec.binary.Base64;标红可以考虑导入依赖
