传递给Spring JDBC LobHandler之后关闭Java InputStream吗?

问题描述

以这种代码传递给Spring JDBC lobCreator.setBlobAsBinaryStream(,,)之后，是否需要在Java中手动关闭InputStream(bean.getContentAsStream())?

Does it need manually close InputStream (bean.getContentAsStream()) in java after pass to Spring JDBC lobCreator.setBlobAsBinaryStream(,,) in such code?

 getJdbcTemplate().execute(
                "INSERT INTO file (" +
                "id, " +                      //1
                "FILE_DATA) " +               //2
                " VALUES (?, ?)",
                 // lobhandler is instance of org.springframework.jdbc.support.lob.OracleLobHandler
                new AbstractLobCreatingPreparedStatementCallback(lobhandler){
                    @Override
                    protected void setValues(PreparedStatement ps, LobCreator lobCreator) throws SQLException, DataAccessException {
                        ps.setString(1, bean.getRecordId());
                        lobCreator.setBlobAsBinaryStream(ps, 2, bean.getContentAsStream(), (int) bean.getContentSize());
                    }
                });

推荐答案

我希望spring将其关闭，但文档未说明.您可以通过创建一个InputStream包装器轻松地进行测试，该包装器记录一条消息或在关闭该消息时引发异常.

I expect spring will close it but the doc does not say. You can easily test by creating an InputStream wrapper that logs a message or throws an exception when it is closed.
