找到关键的一行提示：

Caused by: java.lang.UnsupportedClassVersionError: org/springframework/nativex/NativeListener has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

错误原因：

由:Java .lang. unsupportedclassversionerror引起:org/springframework/nativex/NativeListener已经被一个更最新的Java Runtime版本(类文件版本55.0)编译，这个版本的Java Runtime只识别类文件版本52.0
