Maven項目：與slf4j和logback日誌記錄SolrJ導致SolrException：加載類'org.slf4j.Logger; org.slf4j.Logger'錯誤

我有以下設置：一個Spring應用程序，使用SolrJ與slf4j日誌記錄的logback。當我在我的tomcat服務器上啓動應用程序時，出現下面的錯誤。所以，不知何故SolrJ沒有找到slf4j日誌記錄組件，但我確認了.jar文件實際上在我的WAR的正確lib文件夾中。Maven項目：與slf4j和logback日誌記錄SolrJ導致SolrException：加載類'org.slf4j.Logger; org.slf4j.Logger'錯誤

我對洛部分的pom.xml看起來是這樣的：

<dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-api</artifactId>

而且Maven的依賴關係樹看起來如下：

不幸的是，完全依賴關係樹太長對於這篇文章，但如果你需要任何進一步的信息只是讓我知道。感謝您的任何建議。

編輯1：

有一個在我的 「/ WEB-INF/lib目錄/」 我的WAR文件，它包含所有圖書館目錄下的 「SLF4J-API 1.7.25.jar」 文件。

全Maven的依賴關係樹，我剝不包含 「SLF4J」 部分：

編輯2：

這裏是SLF4J-API 1.7的內容WAR包中的.25.jar。 「org/slf4j/Logger.class」似乎存在。當我部署webapp時，slf4j-api-1.7.25.jar擁有644個權限，我的用戶是該文件的所有者。會導致問題嗎？

編輯3： @AlexC你是對的。我爲「.Logger」而津津樂道發現這一行我solr.xml：

<str name="class">${loggingClass:org.slf4j.Logger;org.slf4j.Logger}</str>

我把它改爲：

<logging> 
    <str name="class">${loggingClass:org.slf4j.Logger}</str> 
    <str name="enabled">${loggingEnabled:true}</str> 
    <watcher> 
     <int name="size">${loggingSize:50}</int> 
     <str name="threshold">${loggingThreshold:WARN}</str> 
    </watcher> 
    </logging>

還是同樣的錯誤，但現在隨着 「org.slf4j.Logger」，而不是（與JCL-過SLF4J，的logback核和無）：

也許從我下面的評論中爲大家澄清：「Solr通過SolrJ集成到我的應用程序中。我不運行一個單獨的Solr實例。我知道這應該只用於調試目的，但我使用Solr並不證明獨立的Solr服務器。「

我試圖通過我的pom.xml中的排除刪除slf4j的所有依賴關係。 ：

只是檢查在運行時環境（例如，在你的WAR/EAR等），是SLF4J-api.jar中存在 –

你應該張貼依賴三，顯示什麼是衝突的根源部分。或者至少有一個是衝突的第一根。 – freedev

我爲您的評論添加了修改。 slf4j-api.jar存在於我的WAR文件中。 – stefanhgm

我發現了一個解決方法，用於我的設置。首先，我添加了所有類型的連接器，將slf4j登錄到我的pom中。xml，由於Solr wiki中的以下句子 。

如果使用的是完全不同的記錄機制的logback一樣，那麼 你必須爲所有三個攔截 - JUL，JCL和log4j的。

此外，我發現Solr代碼導致LogWatcher.java類184行中出現日誌記錄問題（另請參見我的問題中的異常消息）。以下是Github的代碼摘錄。

private static LogWatcher createWatcher(LogWatcherConfig config, SolrResourceLoader loader) { 

    String fname = config.getLoggingClass(); 
    String slf4jImpl; 

    try { 
     slf4jImpl = StaticLoggerBinder.getSingleton().getLoggerFactoryClassStr(); 
     log.debug("SLF4J impl is " + slf4jImpl); 
     if (fname == null) { 
     if ("org.slf4j.impl.Log4jLoggerFactory".equals(slf4jImpl)) { 
      fname = "Log4j"; 
     } else if (slf4jImpl.indexOf("JDK") > 0) { 
      fname = "JUL"; 
     } 
     } 
    } 
    catch (Throwable e) { 
     log.warn("Unable to read SLF4J version. LogWatcher will be disabled: " + e); 
     if (e instanceof OutOfMemoryError) { 
     throw (OutOfMemoryError) e; 
     } 
     return null; 
    } 

    if (fname == null) { 
     log.debug("No LogWatcher configured"); 
     return null; 
    } 

    if ("JUL".equalsIgnoreCase(fname)) 
     return new JulWatcher(slf4jImpl); 
    if ("Log4j".equals(fname)) 
     return new Log4jWatcher(slf4jImpl); 

    try { 
     return loader != null ? loader.newInstance(fname, LogWatcher.class) : null; 
    } 
    catch (Throwable e) { 
     log.warn("Unable to load LogWatcher {}: {}", fname, e); 
     if (e instanceof OutOfMemoryError) { 
     throw (OutOfMemoryError) e; 
     } 
    } 

    return null; 
    } 
}

有問題的部分是最後的try/catch塊，所以它看起來像FNAME == 「org.slf4j.Logger」 是無效的。但是，正如我們在代碼的頂部可以看到的那樣，如果fname == null，字符串「Log4j」將用作回退。所以，我乾脆決定在我的Solr的日誌記錄配置「的Log4j」去（如下圖所示），並讓log4j的環比SLF4J連接器句柄SLF4J的連接。

<solr> 

    ... 

    <logging> 
     <str name="class">Log4j</str> 
     <bool name="enabled">true</bool> 
     <!-- default watcher param --> 
     <watcher> 
      <int name="size">50</int> 
      <str name="threshold">FINEST</str> 
     </watcher> 
    </logging> 

    ... 

</solr>

我想這是不完美的解決方案，但對我來說似乎是一個足夠好的解決辦法。
