I got lost trying to save and read an image file from a db.
I get file upload taken care of where a servlet populates a bean with the image file and other info, but I can't get to be written to the db.
What's the best way to procede, starting with the bean?
Would this be appropriate:
Given the following table:
... waht's the correct way to make the insert? I'm using iBatis for handling the jdbc part of the app.
... partial iBatis sqlMap:
... from what I gathered, pg uses a path to the image file for importing it, so should I store to a temp dir on the server and feed pg the path to it? Would the bean then require a String for the imageBody variable instead of the MultipartFile?
Am I using the datatype for this operation (oid)?
Before this I was able to store the image file in the db as 'bytea' but ran into problems trying to retrieve it:
INFO: Loading XML bean definitions from class path resource [org/springframework/jdbc/support/sql-error-codes.xml] org.springframework.dao.DataIntegrityViolationExce ption: SqlMapClient operation; SQL ; --- The error occurred in com/persistance/sqlmaps_xml/imagesSqlMap.xml. --- The error occurred while applying a result map. --- Check the getImageResult. --- Check the result mapping for the 'imageBody' property. --- Cause: org.postgresql.util.PSQLException: Bad value for type int : \377 ... rest omitted...
... so I'll appreciate any feedback you might have.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
