How to get object from mono without blocking

by

The Mono framework provides asynchronous support for executing tasks without blocking the main thread. To get an object from Mono without blocking, you can use the .subscribe() method and handle the result using a callback function. Here’s an example:

Mono.just("Hello, World!")
    .subscribe(result -> {
      // Handle the result here
      System.out.println(result);
    });

In this example, we create a Mono object using the Mono.just() method and pass it a string value. Then, we call the .subscribe() method on the Mono object and provide a lambda function as the callback. The lambda function receives the result of the Mono object (in this case, the string “Hello, World!”) and we can handle it however we need.

The code inside the lambda function will be executed asynchronously, without blocking the main thread. This allows other tasks to run concurrently, improving the overall performance of your application.

It’s important to note that the .subscribe() method is non-blocking, but it doesn’t return the result directly. If you need to use the result in your code, you can store it in a variable or pass it to another function.

Overall, using the .subscribe() method allows you to get an object from Mono without blocking, enabling more efficient concurrent programming.
