我的 $CLASSPATH 技能不太好，我在设置 mysql-connector 以使用我的 MySQLAccess 类时遇到了问题。我编译并将 MySQLAccess 类放在与 my-sql-connector.jar 相同的目录中这是我的代码:
java -classpath :/home/rick/Downloads/mysql-connector-java-5.1.22/mysql-connector-java-5.1.22-bin.jar MySQLAccess
Exception in thread "main" java.lang.NoClassDefFoundError: MySQLAccess
Caused by: java.lang.ClassNotFoundException: MySQLAccess
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
at java.lang.ClassLoader.loadClass(ClassLoader.java:321)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: MySQLAccess. Program will exit.
最佳答案
放一个 . 也指示当前位置
java -classpath /home/rick/Downloads/mysql-connector-java-5.1.22/mysql-connector-java-5.1.22-bin.jar:. MySQLAccess
