You don’t need this information in production anyways.īut you might need them during development. your persistence.xml file) and set the show_sql parameter to false. It’s pretty obvious how you can fix this performance issue. That’s the kind of achievement you like to report in the next stand-up meeting 🙂 In one of my projects, I improved the performance by 20% within a few minutes by setting show_sql to false. But it is extremely inefficient, especially via as Hibernate does it if you set the show_sql parameter in your Hibernate configuration to true: Hibernate: select Writing some log statements doesn’t sound like a big deal, and there are a lot of applications out there which do exactly that.

It’s the logging of SQL statements in a production environment. Right click on the Myapplication.java class, Run As -> Java Application.The first performance issue is extremely easy to spot and often ignored. Return new ResponseEntity(book, HttpStatus.OK) Īs we are ready with all the changes, let us compile the spring boot project and run the application as a java project. Return new ResponseEntity(HttpStatus.NOT_FOUND) Import class HibernateConfig Environment LocalSessionFactoryBean sessionFactory() ') n(Myapplication.class, args) Īdd the following code to the Hibernate configuration to initialize the Hibernate’s Session-factory object and handle the sql operations. * Main implementation class which serves two purpose in a spring boot application: Configuration and bootstrapping. Always remember, the entry point of the spring boot application is the class containing annotation and the static main method. 3.3.1 Implementation/Main classĪdd the following code the main class to bootstrap the application from the main method. Let’s write all the java classes involved in this application. The updated file will have the following code.Ĭreate a new properties file at the location: Springboothibernatetutorial/src/main/resources/ and add the following code to it.Īpplication.properties # Application configuration.ĭatasource.driver-class-name=.jdbc.Driverĭatasource.url= jdbc:mysql://localhost:3306/springhibernatedb Maven will automatically resolve the other dependencies. Here, we specify the dependencies for the Spring Boot and MySQL. But before starting we are assuming that developers have installed the MySQL on their machine. Creating a Spring Boot applicationīelow are the steps involved in developing the application. If you observe, it has downloaded the maven dependencies and a pom.xml file will be created. Click on Finish and the creation of a maven project is completed.
