idea编译报错 sun.misc.BASE64Decoder升级处理
警告:
17:01:15 /deploy/jenkins/workspace/auto-java-test/utils/ImageBase64Utils.java:67: warning: BASE64Encoder is internal proprietary API and may be removed in a future release
17:01:15 BASE64Encoder encoder = new BASE64Encoder();
import sun.misc.BASE64Decoder;
替代写法:
//从JDK 1.8开始,就提供了java.util.Base64.Decoder和java.util.Base64.Encoder的JDK公共API,可代替sun.misc.BASE64Decoder和sun.misc.BASE64Encoder的JDK内部API。
//byte[] bytes = new BASE64Decoder().decodeBuffer(base64);
byte[] bytes = Base64.getDecoder().decode(base64);
//或者使用方法
import org.apache.commons.codec.binary.Base64;
return Base64.encodeBase64String(encrypted);
