经本人测试 图片、word、excel、等文件可以
如果有人需要将word等比较大的base64再次转成byte[]的话,可能报错base64非法异常问题,问题不是因为转换的base64有问题,而是其转换方法问题,如常用的decode()方法,会因为文件过大报错,解决办法就是:
//base64字符串转成byte[]
public static byte[] decodeFromString(String src) {
return src.isEmpty() ? new byte[0] : getMimeDecoder().decode(src.getBytes(DEFAULT_CHARSET));
}
