In production, there are some exceptions or error that occurs but it's easy to understand finding the root cause and tracing out that bug or exception is really a skillful job. When your customers are using the application and found that application issue, How do you get to know about that problem so you can fix the problem before customers start to complain about the application?

You can start using sentry by simply signing up to the platform https://sentry.io/ and creating a new application. after creating your application, Sentry will give you the app id which is DSN.

In order to integrate sentry in your spring boot, all you need to do is add its dependency in your build.gradle and add some properties in your application.yml file.

Add the following dependency in your build.gradle.

implementation 'io.sentry:sentry-spring-boot-starter:6.0.0'

For Maven users:

<dependency>
    <groupId>io.sentry</groupId>
    <artifactId>sentry-spring-boot-starter</artifactId>
    <version>6.0.0</version>
</dependency>

Sentry supports Spring Boot 2.1.0 and above to report unhandled exceptions.

Then add your sentry DSN in your application property file.

sentry.dsn=https://exampleSomePublicKey@o0.ingest.sentry.io/0

To do the validation of integration with the sentry. just throw a new exception from your application code.

throw new SentryDemoException("This is a Validation Exception.");

Go to your sentry dashboard and you are able to see the exception.
