  • Method Details

    • configureLargeFileSupport

      public static void configureLargeFileSupport()
      Configures Apache POI's internal limits for reading large Excel files.

      Adjusts:

      • ZipSecureFile.setMaxFileCount(1,000,000) — max internal zip entries
      • IOUtils.setByteArrayMaxOverride(500,000,000) — max in-memory byte array size

      Note: These are JVM-global settings and affect all POI operations in the same process.

    • configureLargeFileSupport

      public static void configureLargeFileSupport(int maxFileCount, int maxByteArraySize)
      Configures Apache POI's internal limits with custom values.
      Parameters:
      maxFileCount - Maximum number of zip entries (default: 1,000,000)
      maxByteArraySize - Maximum byte array size in bytes (default: 500,000,000)
