But if you need more detailed tracing in certain JDBC universal driver components, then the bitwise operator will enable you to do this.

If you want to trace more than one specific traceLevel property, then you can use bitwise operator (') to separate the different properties.

如果想跟踪不止一个特定的traceLevel属性，那么可以使用位操作符（）来分隔不同的属性。
