var blob = new Blob([byteArray], {type: contentType});

代码示例来源：origin: org.apache.isis.core/isis-core-applib

@Override
public String toString() {
  return getName() + " [" + getMimeType().getBaseType() + "]: " + getBytes().length + " bytes";
}

@Test
public void when_blob_is_not_null() {
  final Blob val = new Blob("image.png", "image/png", new byte[]{1,2,3,4,5});
  CommonDtoUtils.setValueOn(valueDto, ValueType.BLOB, val, mockBookmarkService);
  final BlobDto blobDto = valueDto.getBlob();
  Assert.assertThat(blobDto, is(notNullValue()));
  Assert.assertThat(blobDto.getBytes(), is(val.getBytes()));
  Assert.assertThat(blobDto.getName(), is(val.getName()));
  Assert.assertThat(blobDto.getMimeType(), is(val.getMimeType().toString()));
}
