Viral, Great job I am newer to SpringHibernate but can created 1st project by following your example. There is one question You created ContactDAO. Insert file data into My. SQL database using JDBCDetails Last Updated on 2. September 2. 01. 7    Print  Email. To store a file into a database table, the table must have a column whose data type is BLOB Binary Large OBject. Assuming we have a My. SQL table called person which is created by the following SQL script CREATE TABLE person. NOT NULL AUTOINCREMENT. Hibernate Update Change Primary Key In Mysql' title='Hibernate Update Change Primary Key In Mysql' />DEFAULT NULL. DEFAULT NULL. photo mediumblob. PRIMARY KEY personid. ENGINEInno. DB AUTOINCREMENT3 DEFAULT CHARSETlatin. We can notice that the column photohas type of mediumblob which is one of four My. Spring 4 MVC with Hibernate 4 MySQL Integration Example annotation based to create a CRUD oriented web application, making use of AOP based transactions. Previous Next In this post, we are going to see integration of Spring MVC, hibernate and mysql CRUD example. We have already seen integration of Spring Rest with. I have the following table in MySQL version 5. DROP TABLE IF EXISTS momentodistribution CREATE TABLE IF NOT EXISTS momentodistribution momentoid. SQLs blob types TINYBLOB 2. BLOB 6. 5,5. 35 bytes 6. KBMEDIUMBLOB 1. MBLONGBLOB 4 GB That means the photo column can store a file up to 1. MB. You can choose which blob type, depending on your need. Now we discuss some techniques used to insert content of a file into the table person, using JDBC. Insert file using standard JDBC API database independent To store content of a file binary data into the table, we can use the following method defined by the interface java. Prepared.

For example String file. Path D PhotosTom. Input. Stream input. Stream new File. Input. Streamnew Filefile. Path. String sql INSERT INTO person photo values. Prepared. Statement statement connection. Statementsql. statement. Blob1, input. Stream. Update. Where connection is a database connection represented by a java. Connection object. The following program connects to a My. SQL database called contactdb and inserts a record with an image file into the table person package net. File. import java. File. Input. Stream. IOException. import java. Input. Stream. import java. Connection. import java. Driver. Manager. import java. Prepared. Statement. SQLException. public class Jdbc. Insert. File. One. String args. String url jdbc mysql localhost 3. String user root. String password secret. String file. Path D PhotosTom. Connection conn Driver. Manager. get. Connectionurl, user, password. String sql INSERT INTO person firstname, lastname, photo values, ,. Prepared. Statement statement conn. Statementsql. statement. String1, Tom. String2, Eagar. Input. Stream input. Stream new File. Input. Streamnew Filefile. Path. statement. Blob3, input. Stream. Update. if row 0. System. out. printlnA contact was inserted with photo image. SQLException ex. Stack. Trace. catch IOException ex. Stack. Trace. In this case, the files content is transferred from client computer to the My. SQL server. This technique is database independent because almost database engines support blob type and the JDBC driver takes care the data transfer transparently. Insert file using specific My. SQL syntax Beside using JDBCs method set. Blob of the Prepared. Statement interface, we can also use My. SQL syntax to achieve the same thing, with the LOADFILE command LOADFILEfilepath For example, the following program inserts a record into the person table with only the image file package net. Connection. import java. Driver. Manager. import java. Prepared. Statement. SQLException. public class Jdbc. Insert. File. Two. String args. String url jdbc mysql localhost 3. String user root. String password secret. String file. Path D PhotosTom. Connection conn Driver. Manager. get. Connectionurl, user, password. String sql INSERT INTO person photo values LOADFILE. Prepared. Statement statement conn. Statementsql. statement. String1, file. Path. Update. if row 0. System. out. printlnA contact was inserted with photo image. SQLException ex. Stack. Trace. In this case, the file must reside in the same machine as My. SQL server. This technique is specific to My. SQL only.    My. SQLs limitation on packet size By default, My. SQL sets a limit on the amount of data can be sent in a query including both the file data and other querys data. This limit is 1. MB and can be configured via a property called maxallowedpacket. If we are trying to store a file whose size exceeds this limit, My. SQL will throw this error com. Packet. Too. Big. Exception Packet for query is too large 4. You can change this value on the server by setting the maxallowedpacket variable. Because 1 MB limit is quite small for binary file, so we usually have to set a higher value when working with blob type. There are two common ways for setting this limit Via My. SQLs configuration file my. Open my. ini file and append the following line at the end maxallowedpacket1. That sets the limit for about 1. MB 1. 04,8. 57,6. Via SQL statement We can also configure the maxallowedpacket variable from the client by sending the following SQL statement before inserting the file SET GLOBAL maxallowedpacket1. That statement becomes effective until the server restarts. For example, the following program sends a query to set new value for maxallowedpacket variable before inserting the file package net. File. import java. File. Input. Stream. IOException. import java. Input. Stream. import java. Connection. import java. Driver. Manager. import java. Prepared. Statement. SQLException. import java.
