如何使用jdbcTemplate将文件插入Oracle？

Question

我试图将字节数组设置为SqlLobValue（），但是它不起作用。

public void sendEmailWithAccountInfoPDF(String toEmail, byte[] pdf) {
        String SQL_ADD_EMAIL = "insert into emails_for_sending " +
        "(to_email, attach_type, attach_name, attach_body) " +
        "values (:to_email, :attach_type, :attach_name, :attach_body);";

   Map<String, Object> params = new HashMap<>();
   params.put("to_email", toEmail);

   params.put("attach_type", "application/pdf");
   params.put("attach_name", "info.pdf");
   params.put("attach_body", new SqlLobValue(pdf));

   jdbcTemplate.update(SQL_ADD_EMAIL, params);
}

但这给了我“ SqlLobValue仅支持SQL类型Blob和Clob”。

LobCreator / LobHandler为LOB输入和输出提供以下支持：

BLOB

byte [] – getBlobAsBytes和setBlobAsBytes

InputStream – getBlobAsBinaryStream和setBlobAsBinaryStream

CLOB

字符串– getClobAsString和setClobAsString

InputStream – getClobAsAsciiStream和setClobAsAsciiStream

读取器– getClobAsCharacterStream和setClobAsCharacterStream
