How to do @Async operation in spring boot

By -
Using @Async annotation we can create the asynchronous method in spring. If we add @Async annotation on the method then spring Will execute the method in a separate thread in the background thread pool.  Enabling @Async support in spring boot To enable asynchronous processing, you need to add @EnableAsync in the spring configuration class. @EnableAsync annotation will look for a method marked with @Async annotation and run them in the background thread pool.  @Configuration @EnableAsync public class AsyncConfig { ... }   @Async has two rules It must be applied to the public method only. Self-invocation is not allowed. That means calling the async method from the same class is not work. The reason for the above rule is very simple The method needs to be public so that can be provided and self-innovation doesn't work because it passes the proxy and call the method directly. The method with void return type The method with a void return type works like a runnable thre...

Microservice Architecture Advantages and Disadvantages

By -
Microservices architecture is a method of developing software systems as a collection of small, independent services that communicate with each other over a network. Each microservice is responsible for a specific business function and runs its own process, which can be deployed and scaled independently of the other services. This approach to software development has several benefits: It allows for faster development and deployment of new features, as each microservice can be developed, tested and deployed independently. It allows for more flexible scaling, as different microservices can be scaled up or down depending on their usage. It promotes a culture of autonomy and ownership among development teams, as each team is responsible for the development and maintenance of their own microservice. It allows for the use of different technologies and programming languages for different microservices. It helps to reduce the complexity of the overall system, as each microservice can be unders...
