如果有人遇到相同的问题，则发布此解决方案，我通过base64将字节数组编码为字符串来解决此问题，如下所示。
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
workbook.write(outputStream);
String res = Base64.getEncoder().encodeToString(outputStream.toByteArray());
在JavaScript中，我从下面的链接使用base64ToBlob方法解码了该字符串
http://codingdict.com/questions/8184
function base64toBlob(base64Data, contentType) {
contentType = contentType || '';
var sliceSize = 1024;
var byteCharacters = atob(base64Data);
var bytesLength = byteCharacters.length;
var slicesCount = Math.ceil(bytesLength / sliceSize);
var byteArrays = new Array(slicesCount);
for (var sliceIndex = 0; sliceIndex < slicesCount; ++sliceIndex) {
var begin = sliceIndex * sliceSize;
var end = Math.min(begin + sliceSize, bytesLength);
var bytes = new Array(end - begin);
for (var offset = begin, i = 0; offset < end; ++i, ++offset) {
bytes[i] = byteCharacters[offset].charCodeAt(0);
}
byteArrays[sliceIndex] = new Uint8Array(bytes);
}
return new Blob(byteArrays, { type: contentType });
}
