slf4j绑定器_用于ADFLogger的SLF4J绑定–缺少的部分

發布時間：2023/12/3 编程问答 30 豆豆

生活随笔收集整理的這篇文章主要介紹了 slf4j绑定器_用于ADFLogger的SLF4J绑定–缺少的部分小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

slf4j綁定器

由于最好的原因，在我的日常工作中，我希望為ADF Logger Oracle ADF提供一個SLF4J適配器。毫不奇怪，slf4j沒有用于ADFLogger的適配器，但是由于ADFLogger只是Java Util Logging的輕巧包裝，因此花了一個多小時來填補這一空白。

存儲庫中的測試用例（更像是主程序）將確認適配器框架與Oracle Diagnostic Logging配合良好，而不會破壞日志消息的格式。（或多或少是ADFLogger提供的唯一優勢）。

您可以從github的存儲庫下載整個代碼庫。或者，如果您只對裝訂罐感興趣，請在此處下載。

日志級別：

考慮到ADF記錄器（7）上的日志級別很多，而SLF4J（5）的級別較少，因此在ADF記錄器的某些級別上做出了折衷。映射如下：

注意：在此調整過程中，不再支持日志級別FINER和CONFIG。

用法：

只需繼續使用SLF4J實例替換您的ADFLogger。

private static final Logger slfLogger = LoggerFactory.getLogger(LoggingChecker.class);

代替

private static final ADFLogger adfLogger= ADFLogger.createADFLogger(LoggingChecker.class);

記錄方式

一個。記錄到各個級別

@Testpublic void testLoggerLevels(){adfLogger.finest("finest Message from ADF Logger");slfLogger.trace("finest Message from SLF Logger");adfLogger.fine("fine Message from ADF Logger");slfLogger.debug("fine Message from SLF Logger");adfLogger.info("info Message from ADF Logger");slfLogger.info("info Message from SLF Logger");adfLogger.warning("warning Message from ADF Logger");slfLogger.warn("warning Message from SLF Logger");adfLogger.severe("severe Message from ADF Logger");slfLogger.error("severe Message from SLF Logger");}

b。記錄異常

其中dummyException繼承了Throwable

C。記錄參數

開發說明：

ADF Logger Adapter框架由兩個核心類（ ADFLoggerFactory.java和ADFLoggerAdapter.java ）以及其他三個幫助器類組成。

適配器可以支持多個記錄器，包括ADFLogger的ROOT記錄器（這是默認記錄，名稱為空字符串）。

SLF4J使用ADFLoggerFactory.java實例化ADFLoggerAdapter也就不足為奇了。

對于每個Logger實例， ADFLoggerAdapter.java組成一個ADFLoggerAdapter.java實例（綁定到記錄器名稱），并將調用委托給ADFLogger本身。

fillCallerData方法從整個日志記錄堆棧中篩選ADFLoggerAdapter的堆棧框架，以便將調用者類和方法名稱保留為主機應用程序中的名稱，而不是Adapter框架類中的名稱。

測試用例（很好）

public class TestClass {private static final ADFLogger adfLogger= ADFLogger.createADFLogger(TestClass.class);private static final Logger slfLogger = LoggerFactory.getLogger(TestClass.class);private List<String> dummyList1=null;private List<Integer> dummyList2=null;private Exception dummyException=null;@Beforepublic void setUp(){dummyList1=new ArrayList<String>();dummyList1.add("Rock");dummyList1.add("Paper");dummyList1.add("Scissors");dummyList2=new ArrayList<Integer>();dummyList2.add(21);dummyList2.add(22);dummyList2.add(23);dummyException=new Exception("Mind blowing Exception");}@Testpublic void testLoggerLevels(){adfLogger.finest("finest Message from ADF Logger");slfLogger.trace("finest Message from SLF Logger");adfLogger.fine("fine Message from ADF Logger");slfLogger.debug("fine Message from SLF Logger");adfLogger.info("info Message from ADF Logger");slfLogger.info("info Message from SLF Logger");adfLogger.warning("warning Message from ADF Logger");slfLogger.warn("warning Message from SLF Logger");adfLogger.severe("severe Message from ADF Logger");slfLogger.error("severe Message from SLF Logger");}@Testpublic void testException(){adfLogger.severe("severe Message from ADF Logger", dummyException);slfLogger.error("severe Message from SLF Logger", dummyException);}@Testpublic void testParameters(){adfLogger.severe("severe Message from ADF Logger Param :{0}", dummyList1 );slfLogger.error("severe Message from SLF Logger Param :{}", dummyList1);adfLogger.severe("severe Message from ADF Logger Param 1 :[{0}] \n [{1}]", new Object[]{dummyList1, dummyList2} );slfLogger.error("severe Message from SLF Logger Param :{} \n {} ", dummyList1, dummyList2);slfLogger.error("severe Message from SLF Logger Param :[{}] \n [{}] ", new Object[]{dummyList1, dummyList2});}
