- This article contains Microsoft Visual C#.NET code samples that demonstrate how to use the SqlDataAdapter object to update a SQL Server database with data modifications that are run on a DataSet object that is populated with data from a table in the database. Requirements The following list outlines the recommended hardware, software, network infrastructure, skills and knowledge, and service.
- Dec 19, 2018 How to use Spring Data JDBC with Azure SQL Database.; 3 minutes to read; Contributors. In this article Overview. This article demonstrates creating a sample application that uses Spring Data to store and retrieve information in an Azure SQL Database using Java Database Connectivity (JDBC).
Recently I had to update my Spring based app config to use Windows Authentication for connecting SQL Server Database. Previously I had datasource bean in my applicationContext as follows:
As you can see this is SQL Authentication and its using Microsoft JDBC type 4 Driver verison 4.0. You can download the jdbc dependency from here.
There are two ways to do Windows Authentications: Native way through the integrated Security which will works only on Windows OS. Other way is using Kerberos protocol, a network-based authentication where you could supply the username/password. Here is the link you can checkout to learn more. I used the first way since my app was running on windows and its quickest and easiest way to do. Here are the steps:
- add integratedSecurity=true property on above configuration and remove username/password as they are not needed.
- find sqljdbc_auth.dll file from microsoft jdbc driver installation folder, one you installed previously from the jdbc driver link. The path would be something like:
<installation directory>sqljdbc_<version><language>auth
- copy sqljdbc_auth.dll file to your JAVA_HOME/bin folder.
- finally start your application/webservice/appserver( like tomcat) using windows credentials that you wanted to used to connect SQL Sever. Now you can inject your datasource anyway you need it to connect the db. That should do it!!

Overview
This article demonstrates creating a sample application that uses Spring Data to store and retrieve information in an Azure SQL Database using Java Database Connectivity (JDBC).
Prerequisites
The following prerequisites are required in order to complete the steps in this article:
- An Azure subscription; if you don't already have an Azure subscription, you can activate your MSDN subscriber benefits or sign up for a free Azure account.
- A supported Java Development Kit (JDK). For more information about the JDKs available for use when developing on Azure, see https://aka.ms/azure-jdks.
- Apache Maven, version 3.0 or later.
- Curl or similar HTTP utility to test functionality.
- A Git client.
Create an Azure SQL Satabase
Create a SQL database server using the Azure Portal
Note
You can read more detailed information about creating Azure SQL databases in Create an Azure SQL database in the Azure portal.
Browse to the Azure portal at https://portal.azure.com/ and sign in.
Click +Create a resource, then Databases, and then click SQL Database.
Specify the following information:
- Database name: Choose a unique name for your SQL database; this will be created in the SQL server that you will specify later.
- Subscription: Specify your Azure subscription to use.
- Resource group: Specify whether to create a new resource group, or choose an existing resource group.
- Select source: For this tutorial, select
Blank database
to create a new database.
Click Server, then Create a new server, and then specify the following information:
- Server name: Choose a unique name for your SQL server; this will be used to create a fully-qualified domain name like wingtiptoyssql.database.windows.net.
- Server admin login: Specify the database administrator name.
- Password and Confirm password: Specify the password for your database administrator.
- Location: Specify the closest geographic region for your database.
When you have entered all of the above information, click Select.
For this tutorial, specify the least-expensive Pricing tier, and then click Create.
Configure a firewall rule for your SQL server using the Azure Portal
Browse to the Azure portal at https://portal.azure.com/ and sign in.
Click All Resources, then click the SQL server you just created.
In the Overview section, click Show firewall settings
In the Firewalls and virtual networks section, create a new rule by specifying a unique name for the rule, then enter the range of IP addresses that will need access to your database, and then click Save.
Retrieve the connection string for your SQL server using the Azure Portal
Browse to the Azure portal at https://portal.azure.com/ and sign in.
Click All Resources, then click the SQL database you just created.
Click Connection strings, then click JDBC, and copy the value in the JDBC text field.
Configure the sample application
Open a command shell and clone the sample project using a git command like the following example:
Locate the application.properties file in the resources directory of the sample project, or create the file if it does not already exist.
Open the application.properties file in a text editor, and add or configure the following lines in the file, and replace the sample values with the appropriate values from earlier:
Where:
Parameter Description spring.datasource.url
Specifies an edited version of your SQL JDBC string from earlier in this article. spring.datasource.username
Specifies your SQL administrator name from earlier in this article, with the shortened server name appended to it. spring.datasource.password
Specifies your SQL administrator password from earlier in this article. Save and close the application.properties file.
Package and test the sample application
Build the sample application with Maven; for example:
Start the sample application; for example:
Create new records using
curl
from a command prompt like the following examples:Your application should return values like the following:
Retrieve all of the existing records using
curl
from a command prompt like the following examples:Your application should return values like the following:
Summary
In this tutorial, you created a sample Java application that uses Spring Data to store and retrieve information in an Azure SQL database using JDBC.
