我在尝试连接到SQL Server 2008数据库时遇到问题,这是一个完整的例外:
java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class com.microsoft.sqlserver.jdbc.SQLServerDriver)

异常指向这行代码:
private static String DRIVER_SQLSERVER="com.microsoft.sqlserver.jdbc.SQLServerDriver";
我该如何解决这个问题?
答案 0 :(得分:3)
当您尝试加载使用比运行应用程序的Java版本更高版本的Java编译的类时,抛出此异常。
请参阅UnsupportedClassVersionError
java -version
javap -verbose com.microsoft.sqlserver.jdbc.SQLServerDriver
