java8之后的兼容性

​

缺少javafx和javax,添加javax

<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.3.2</version>
</dependency>

如何在java8以上版本使用javafx?

fx下载地址 https://gluonhq.com/products/javafx/ ​ Open the command prompt and run java --module-path <path to unzipped folder>/lib --add-modules ALL-MODULE-PATH -jar <path to mcaselector-1.16.3.jar> where you replace everything in <> with the appropriate paths.

JDK1.8 找不到 sun.misc.BASE64Decoder 的解决方法

使用JDK.18 自带

java.util.Base64
java.util.Base64.Encoder;
java.util.Base64.Decoder;

代替sun.misc.BASE64Decoder 例子1

BASE64Decoder base64 = new BASE64Decoder();
byte[] buffer = base64.decodeBuffer(publicKeyStr);

替代方法

Decoder decoder=Base64.getMimeDecoder(); //注不要使用.getDecoder();
byte[] buffer =decoder.decode(publicKeyStr);
