log4jdbc Java 8 兼容性

Question

我正在尝试使用 log4jdbc 监视我的 MySQL 数据库查询。我有一个运行 Java 8 的 WSO2 身份服务器。我按照 [1] 中的说明进行操作，并收到以下错误。

[2019-01-11 15:19:37,590] ERROR {org.wso2.carbon.user.core.common.DefaultRealm} -  nullType class java.lang.reflect.InvocationTargetException

我的 log4jdbc 版本是 log4jdbc4-1.2.jar。任何帮助表示赞赏。提前致谢。

这是一个找不到类的错误。你可以试试这个类名吗？<driverClassName>net.sf.log4jdbc.DriverSpy</driverClassName>参考： http:&nbsp;//movingaheadblog.blogspot.com/2016/07/how-to-use-log4jdbc-with-wso2-products_28.html
