Exception in thread "main" java.lang.RuntimeException: Cannot resolve classpath entry: mysql-connector-java-5.1.45.jar at org.mybatis.generator.internal.util.ClassloaderUtility.getCustomClassloader(ClassloaderUtility.java:50) at org.mybati是什么意思

这一个Java异常，通常是由于MyBatis Generator无法找到或解析mysql-connector-java-5.1.45.jar类路径导致的。MyBatis Generator是一个用于生成MyBatis持久层代码的工具，需要指定数据库驱动程序的类路径进行代码生成。如果指定的类路径不正确或无法找到，则会抛出类似的异常。建议检查类路径是否正确，以及mysql-connector-java-5.1.45.jar是否存在于正确的位置。
