How to share your Programming Articles on Javarevisited for more Exposure

Hello, Friends,
I have been writing Java articles for a long time and one thing I have learned from that experience is that learning makes you a better Programmer and Software developer. It's also one of the important tips I have shared on how to become a better programmer article long back. It seems many people like that and contacted me about that but their main difficulty was that after writing one or two articles they get frustrated because no one was reading it. Well, I can understand but it takes a lot of time and effort to build a following. I am fortunate and really grateful that Java community has given me so much love and that's why I have decided to do my bit to promote and encourage every new Java programmer/writer/blogger to the best I can.

Spring Boot Error - Error creating a bean with name 'dataSource' defined in class path resource DataSourceAutoConfiguration

Hello guys, If you are using Spring Boot and getting errors like "Cannot determine embedded database driver class for database type NONE" or "Error creating a bean with name 'dataSource' defined in class path resource ataSourceAutoConfiguration" then you have come to the right place. In this article, we'll examine different scenarios on which this Spring Boot error comes and what you can do to solve them. The general reason for this error is Spring Boot's auto-configuration, which is trying to automatically configure a DataSource for you but doesn't have enough information. It is automatically trying to create an instance of DataSourceAutoConfiguration bean and it's failing.

How to Convert Result of SELECT Command to Comma Separated String in SQL Server

Sometimes, you need the result of the SQL SELECT clause as a comma-separated String e.g. if you are outputting ids of white-listed products. By default, the SELECT command will print each row in one line and you get a column of names or ids. If you need a comma-separated String then you probably need to use a text editor like Notepad++, Edit Plus, or a tool like Microsoft Excel to convert that column of values into a big CSV String. I often use a text editor like edit plus to replace the \n to comma (,) to create such CSV string because it supports regular expression-based find and replaces operation.
