JDBCTemplate/NamedParameterJdbcTemplate 插入失败 FileItem/Blob

JDBCTemplate/NamedParameterJdbcTemplate failed to insert FileItem/Blob

我有一个正常的 PreparedStatement 插入 FileItem fileItem 到 BLOB 列:

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

问题我可以输入FileItemNamedParameterJdbcTemplate:

我试过 Types.BLOB:

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

但是遇到异常

与参数 BLOB filejdbcTemplate 相同的错误:

jdbcTemplate.update(INSERT_FILE, file);

使用与 FileInputStream

不同的参数同样失败

我正在尝试保存(二进制)图像文件

仅当我将参数类型更改为 byte[]:

时才有效
 byte[] blob

并在插入中使用它:

jdbcTemplate.update(INSERT_FILE, blob);
