在cloudfoundry發佈項目時出現錯誤java.io.FileNotFoundException（log4j日誌文件）

Question

我打算將web應用程序與mysql服務一起移至cloudfoundry。但是我得到了錯誤。

它與當地的環境工作得很好。日誌文件也會生成。

下面是錯誤日誌：

log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository. 
Stopping Tomcat because the context stopped. 

的log4j.xml：

<appender name="fileAppender" class="org.apache.log4j.RollingFileAppender"> 
    <param name="MaxFileSize" value="25MB" /> 
    <param name="MaxBackupIndex" value="10" /> 
    <param name="File" value="/logs/abc-web.log" /> 
    <layout class="org.apache.log4j.PatternLayout"> 
     <param name="ConversionPattern" value="%d [%t] %-5p: %m (%c)%n" /> 
    </layout> 
</appender> 

Answer 1

的Log4j將create directories而目錄和它的父目錄不存在。

Log4j在創建目錄或文件時拋出FileNotFoundException失敗，沒有文件priviledge。

用您的應用程序用戶檢查文件priviledge。

public 
    synchronized 
    void setFile(String fileName, boolean append, boolean bufferedIO, int bufferSize) 
                  throws IOException { 
    LogLog.debug("setFile called: "+fileName+", "+append); 

    // It does not make sense to have immediate flush and bufferedIO. 
    if(bufferedIO) { 
     setImmediateFlush(false); 
    } 

    reset(); 
    FileOutputStream ostream = null; 
    try { 
      // 
      // attempt to create file 
      // 
      ostream = new FileOutputStream(fileName, append); 
    } catch(FileNotFoundException ex) { 
      // 
      // if parent directory does not exist then 
      //  attempt to create it and try to create file 
      //  see bug 9150 
      // 
      String parentName = new File(fileName).getParent(); 
      if (parentName != null) { 
      File parentDir = new File(parentName); 
      if(!parentDir.exists() && parentDir.mkdirs()) { 
       ostream = new FileOutputStream(fileName, append); 
      } else { 
       throw ex; 
      } 
      } else { 
      throw ex; 
      } 
    } 

Answer 2

我有這個相同的FileNotFound異常問題。

我的解決辦法是從價值，從而去除附加「/」：

<param name="File" value="logs/abc-web.log" />
