PMD規則之Jakarta Commons Logging Rules

·  UseCorrectExceptionLogging: To make sure the full stacktrace is printed out, use the logging statement with 2 arguments: a String and a Throwable.

翻譯   使用正確的異常日誌：保證列印出完全的異常堆棧，記錄或拋出異常日誌時使用包含兩個參數的運算式：一個參數是字串，一個是Throwable類型

·  ProperLogger: A logger should normally be defined private static final and have the correct class. Private final Log log; is also allowed for rare cases where loggers need to be passed around, with the restriction that the logger needs to be passed into the constructor.

翻譯   合適的日誌記錄器：日誌記錄器一般應該被定義為private static final的，而且應該有正確的類。Private final Log log;也被允許使用在需要傳遞的這種極少的情況中，具有這種限制日誌記錄器就需要被傳入構造器中。
