用spring jdbctemplate

Question

我正在尝试使用jdbctemplate通过以下代码

在表中插入blob

LobHandler handler = new DefaultLobHandler();
int dbresponse = jdbcTemplate.update(DBConstants.INSERT_INVOICE, new Object[]{invoiceBean.getVendorid(),
        new SqlLobValue(invoiceBean.getInvoiceImage(), invoiceBean.getInvoiveImageLength(), handler), invoiceBean.getInvoiceDate()}, 
        Types.INTEGER,Types.BLOB, Types.VARCHAR);

但得到以下错误

    Caused by: java.sql.SQLException: Invalid argument value: java.io.NotSerializableException

.......

    Caused by: java.io.NotSerializableException: org.springframework.jdbc.core.support.SqlLobValue

我将invoiceBean类设为Serializable但得到了相同的错误。

注意：小尺寸的图像会成功插入数据库，但问题是图像大小通常大于1 MB

请咨询!!!

我认为最后一个参数应该是一个int数组：

LobHandler handler = new DefaultLobHandler();
int dbresponse = jdbcTemplate.update(
                       DBConstants.INSERT_INVOICE, 
                       new Object[]{
                               invoiceBean.getVendorid(),
                               new SqlLobValue(invoiceBean.getInvoiceImage(), invoiceBean.getInvoiveImageLength(), handler), 
                               invoiceBean.getInvoiceDate()}, 
                       new int[] {Types.INTEGER, Types.BLOB, Types.VARCHAR});
