mysql - 在Eclipse中创建连接-ClassNotFoundException:com.mysql.jdbc.Driver

我没有在代码中做任何事情——我只是创建了一个eclipse连接，似乎无法ping它。连接属性：
jar就是我说的位置（$GLASSFISH\HOME\domains\domain1\lib\ext），但是我得到：

最佳答案

这个zip很可能是MySQL Connector/J的发行zip，在这个zip的内部是带有驱动程序的mysql-connector-java-5.1.27-bin.jar库。所以您需要先解压缩它，然后添加jar-library而不是zip。
