JDBC存储BLOB数据 出现如下错误

[weixin_37653845]

ps.setBytes(1,byte[])
当byte[]大于4K的数据时 就报超出最大长度 小于4K的可以正常存入
转换思路Blob b= conn.createBlob() ;
ethod "createBlob" with signature "()Ljava/sql/Blob;" is not applicable on this object
继续转换思路存入 ps.setBlob(1, citvo.getInputStream());
爆出Caused by: java.lang.AbstractMethodError: org.apache.commons.dbcp.DelegatingPreparedStatement.setBlob(ILjava/io/InputStream;)V
继续尝试 ps.setBinaryStream(1, citvo.getInputStream());
Caused by: java.lang.AbstractMethodError: org.apache.commons.dbcp.DelegatingPreparedStatement.setBinaryStream(ILjava/io/InputStream;)V
