jjwt | Java JWT : JSON Web Token for Java and Android | Authentication library

I am currently working on a Spring Project, which I am new to, and have no idea why this dependency I got from the maven repository will now resolve itself. I have tried to use both the separated dependency (jjwt-api, etc..) and the one pasted in my pom.xml below but it will not resolve. If anyone can help me figure this out that would great appreciated.

Spring v2.6.4 Java JDK 17 Error message: Dependency 'com.auth0:java-jwt:3.18.3' not found

I have this gradle configuration with the following dependencies:

The stack used in the API is: Spring-boot, Spring Webflux, Hibernate Reactive 1.1.3 and Postgresql.

I'd like to extract a string value from a Mono called desiredField and add it to a hashmap. I'm showing the DB, model, repository and the util module where all this is happening.

The JWTUtil is used to generate a JWT token for login purposes in the API. The JWTController is working fine, coming the token in response! The only thing is that a cannot extract de string value from a Mono.

I've tried two approaches. The reactive way, using the subscribe method. And the blocking way using the block method. These two approches are shown below with their own console prints.

In the first approach (the reactive way) I couldn't extract the desiredField from the Mono. The token comes in the response but without the desiredField in the token claims. The desiredField live only inside de stream (see console log prints), outside is null.

In the second approach (blocking way) there are an infinite loop error without getting the token in the response.

Could you help me to extract this value from the Mono?

Thanks in advance!

I am trying to integrate what is done in this official Vaadin video tutorial (implement back end push notification) into my Spring Boot project. I am finding some problem trying to understand how to correctly integrate Vaadin framework into my existing Spring Boot project pom.xml file in order to have all the dependencies needed to work.

So basically this is the video tutorial link: https://www.youtube.com/watch?v=M5sbGvW3S4I

and this is the related GitHub link of this tutorial example code: https://github.com/marcushellberg/fusion-push-notifications

This is the pom.xml of my already existing Spring Boot project where I need to insert Vaadin framework and the related example project dependencies (needed to implement the desired behavior)

I try to fill up an Java Object with a Json String, which can come with different kinds of variable names for the same field. That's why I try to use @JsonAlias. Unfortunately, I couldn't make it work yet for unknown reasons..

Here is my example:

The Java Object:

I was trying to follow this video tutorial to add AOP to my Spring Boot project in order to perform log operation: https://www.youtube.com/watch?v=RVvKPP5HyaA

But it is not working, it is not logging anything.

So this is my pom.xml file:

Trying to add Springdoc to spring-boot-2.6.2 project. Application runs on embedded jetty server. Actuator runs ok with this below pom.xml setup.

When I try to run the application, below error occurs. Since I think this happens because of one of the dependencies, I tried to organize dependencies.

I was given an application after half development, and I had to finish the development, but because of licensing issues, I was asked to remove mongodb and use couchdb instead. Now, I have removed all instances of mongodb connections in the code, removed mongo connection properties from application.properties, but I still keep getting the following error when I start the spring application.

My pom.xml looks like this, I can't remove mongo dependency from it because still using bson document class.

4.0.0

I'm trying to upgrade log4j library in my spring boot projects :
