![]() ![]() The best way to activate the logging of executed SQL queries is to set the log level of the category to DEBUG. Let’s start with the logging of the executed SQL statements. With the correct logging configuration, you get all the information you’re looking for. Hibernate writes log messages telling you:Īs most frameworks and applications, Hibernate uses different categories and log levels to log this information. It’s no surprise that Hibernate Logging has all the information you need to understand how it interacts with the database. Let’s look at both options closely before showing you how you can use them to find different performance problems. That’s why I prefer Hibernate’s internal logging and Retrace. However, you should choose the tool you feel most comfortable with.Īs a Java developer, I don’t like to work with database logs, and I know that I can’t always replace the JDBC data source. You can analyze your database logs, activate Hibernate’s internal logging, use a JDBC data source that logs all executed statements or use an external tool like Retrace to monitor your system.Īll of these options can help you better understand how Hibernate interacts with the database. There are lots of different ways you can do that. ![]() The best way to avoid these Hibernate performance issues is to monitor the database interactions during development, test and production. That makes it hard to find inefficiencies and potential performance problems before they cause trouble in production. Options to Monitor Database InteractionsĪs a developer using Hibernate, you most often don’t know if or when Hibernate will execute an SQL statement for your call of a method on the EntityManager. This post will show you how to detect Hibernate performance issues when your application is in development and production. Hibernate uses a lot of internal optimizations and hides all database interactions behind its API. But this abstraction also has its downsides. One of its most popular implementations is the Hibernate ORM, because it uses object-relational mapping to abstract database interactions and makes implementing simple CRUD operations very simple. The Java Persistence API (JPA) is used in most Java applications to interact with a relational database. ![]()
