我计划将 Web 应用程序与 mysql 服务一起移动到 cloudfoundry。但我得到了错误。

它在当地环境下工作正常。日志文件也会生成。

以下是错误日志：

Stopping Tomcat because the context stopped.

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>

我遇到了同样的 FileNotFound 异常问题。

我的解决方案是从值中删除附加的“/”，如下所示：

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

Log4j 将在目录及其父目录不存在时创建目录。

Log4j 在没有文件特权的情况下创建目录或文件失败时抛出 FileNotFoundException。

与您的应用用户一起检查文件权限。

  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;
          }
    }
