JDBCTemplate / NamedParameterJdbcTemplate無法插入FileItem / Blob

Question

我有一個普通的PreparedStatement將FileItem fileItem插入BLOB列：

ps.setBinaryStream(1, fileItem.getInputStream(), (int) fileItem.getSize());

我可以將FileItem輸入NamedParameterJdbcTemplate ：

我嘗試使用Types.BLOB ：

MapSqlParameterSource paramSource = new MapSqlParameterSource();
paramSource.addValue("blob",  fileItem.getInputStream(), Types.BLOB);
jdbcTemplate.update(INSERT_FILE, paramSource);

但是有例外

SQL state [99999]; error code [17004]; Invalid column type; nested exception is java.sql.SQLException: Invalid column type

與參數BLOB file jdbcTemplate相同的錯誤：

jdbcTemplate.update(INSERT_FILE, file);

與File和InputStream參數類似的失敗

我正在嘗試保存（二進制）圖像文件

Answer 1

僅當我將參數類型更改為byte[]時才有效：

 byte[] blob

並在插入中使用它：

jdbcTemplate.update(INSERT_FILE, blob);
