Out of the box, Spring Boot is very easy to use with the H2 Database. Now, create a DAO (Data Access Object, also called a Repository by Spring) class for each entity in the com.okta.developer.postgresql.dao package: You now have DAOs for each entity. I’m not sure what situation you’re referring to since the first example is about jdbc and the second about hibernate. First, you need to create a new project with the required dependencies. com.microsoft.sqlserver mssql-jdbc 7.0.0.jre8, I am getting following error when executing the test: [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.426 s <<< FAILURE!
Now the application starts and you should be able to open http://localhost:8080 in your browser.
