Memory Profiling вЂ“ This provides the in-depth understand of heap usage by the application. Time Profiling вЂ“ This measures the execution paths of your application on the method level. Before we run the test, we should understand the basic functionality of JProfiler and how it will help us in performance improvement.

JProfiler (standalone or plugin in IntelliJ)ДЇirst JProfiler is a tool to understand what is going on inside a running JVM.

So as part of this past, I want to debunk few myths around this and why a developer should equally focus on a tool like JProfiler to check the performance. Especially since performance team members are not writing the code. This approach, despite might be working, can have its flaws.

Many times, this is left to specialized performance teams or developers who know the tools well, but donвЂ™t know much about the code that they are trying to measure the performance. That's it! We just have to change it once at the application.properties to let Spring Boot know which environment the code is deployed in, and it will do the magic with the setting.If you are a developer, some point of time you will have to use JProfiler for measuring the performance of your application. This should be picked, and the message will be overridden with the PROD message. We will see MySQL with High Config for DB. With the profile in DEV mode, and it should pick H2 DB. We will use the application.properties to use the key below: =devДЇrom here, Spring Boot will know which profile to pick.

One last setting is how to let the system know that this is DEV, TEST, or PROD. The other two beans will not be created at all. We have used the to let the system know that this is the BEAN that should be picked up when we set the application profile to DEV.

Let's configure in the DBConfiguration.class to pick the correct one. In TEST, we will be using a lower instance of RDS MySQL database, and in PROD, we will use a higher instance of the MySQL database. In DEV, we will use an in-memory database: I will now define DB configuration properties for in respective properties file and add code in DBConfiguration.class to pick the appropriate settings. Of course, the application.properties will remain as a master properties file, but if we override any key in the profile-specific file, the latter will gain precedence. Then, we need to create three application.properties: The solution would be to create more property files and add the 'profile' name as the suffix and configure Spring Boot to pick the appropriate properties based on the profile. So, how will we segregate the properties based on the environment? But, Spring Boot - by default - provides just one property file ( application.properties). In this demo application, we will see how to configure different databases at runtime based on the specific environment by their respective profiles.ДЄs the DB connection is better to be kept in a property file, it remains external to an application and can be changed. Next, we need to import the project into STS as a Maven Project. Let's start with setting up a Spring Boot application from the Spring Starter. This article will demonstrate how to setup Profiles for your Spring Boot application.

Don't worry, we will see how to set it up. We make properties files for each environment and set the profile in the application accordingly, so it will pick the respective properties file. These environments host specific configurations called Profiles. For example, in DEV, we do not need to constantly check database consistency. What AreВ Profiles?Д®very enterprise application has many environments, like:Дev | Test | Stage | Prod | UAT / Pre-ProdД®ach environment requires a setting that is specific to them. In this post, we will talk about one feature in particular: profiles. There are some features that every technology has and it is very useful in enterprise applications. Spring Boot is gaining popularity like never before, and I know it will be a persistent player in the coming months.
