Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Handling concurrency in an application can be a tricky process with many potential pitfalls. A solid grasp of the fundamentals will go a long way to help minimize these issues.

Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

End-to-end testing is a very useful method to make sure that your application works as intended. This highlights issues in the overall functionality of the software, that the unit and integration test stages may miss.
Playwright is an easy-to-use, but powerful tool that automates end-to-end testing, and supports all modern browsers and platforms.
When coupled with LambdaTest (an AI-powered cloud-based test execution platform) it can be further scaled to run the Playwright scripts in parallel across 3000+ browser and device combinations:

In the previous article, we were focusing on EC2; now, let’s move on to the Relational Database Service.
1. RDS Support
1.1. Simple Configuration
Spring Cloud AWS can automatically create a DataSource just by specifying the RDS database identifier and the master password. The username, JDBC driver, and the complete URL are all resolved by Spring.
If an AWS account has an RDS instance with DB instance identifier as spring-cloud-test-db having master password se3retpass, then all that’s required to create a DataSource is the following line in application.properties:
cloud.aws.rds.spring-cloud-test-db.password=se3retpassThree other properties can be added if you wish to use values other than the RDS default:
cloud.aws.rds.spring-cloud-test-db.username=testuser
cloud.aws.rds.spring-cloud-test-db.readReplicaSupport=true
cloud.aws.rds.spring-cloud-test-db.databaseName=test1.2. Custom Datasource
In an application without Spring Boot or in cases where custom configurations are required, we can also create the DataSource using the Java-based configuration:
@Configuration
@EnableRdsInstance(
dbInstanceIdentifier = "spring-cloud-test-db",
password = "se3retpass")
public class SpringRDSSupport {
@Bean
public RdsInstanceConfigurer instanceConfigurer() {
return () -> {
TomcatJdbcDataSourceFactory dataSourceFactory
= new TomcatJdbcDataSourceFactory();
dataSourceFactory.setInitialSize(10);
dataSourceFactory.setValidationQuery("SELECT 1");
return dataSourceFactory;
};
}
}Also, note that we need to add the correct JDBC driver dependency.
2. Conclusion
In this article, we had a look at various ways of accessing AWS RDS service; in the next and final article of the series, we’ll have a look at AWS Messaging support.
The code backing this article is available on GitHub. Once you're logged in as a Baeldung Pro Member, start learning and coding on the project.
