java - 传递到 Spring JDBC LobHandler 后关闭 Java InputStream？

Question

在这样的代码中传递给Spring JDBC lobCreator.setBlobAsBinaryStream(,,)后是否需要手动关闭java中的InputStream(bean.getContentAsStream())？

 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());
                    }
                });

我预计 spring 会关闭它，但文档没有说。您可以通过创建一个记录消息或在关闭时引发异常的 InputStream 包装器来轻松进行测试。
