Java-Spring | Tutoriales Spring Framework

I created a simple example, only acts Resource server to provide APIs for clients.

The complete codes can be found on Github - hantsy/spring-webmvc-auth0-sample.

I have browsed Spring security samples, it used a jwk-set-uri, in my application, I used issuer-uri instead.

I'm using Katharsis in my spring boot application in order to support json-api.

I setup Katharsis using Resources as described here: https://www.baeldung.com/json-api-java-spring-web-app

Now, I want to add another custom filter to my spring boot app. I tried adding this filter:

I am using Okta to handle authentication and authorization in a Spring Boot REST(ful) API Resource Server. I started from an example they provide here. To handle users, I implemented a filter to store an entity (in my relational database) containing the uid claim before each request, since every route of my application requires authentication. Here is the code for the filter:

I have one java-spring application with 2 maven dependencies in different repositories, but in the same group. I used gitlab-ci to deploy the jar in 2 project package registries, but I cannot retrieve them (I can with only one dependency, setting its project repo, in the spring application pom) . For the 2 dependencies, I wrote the same ci-settings.xml:

We are developing an application where we will generate forms at run time. Now we need to perform CRUD operations on the data of the dynamic form.

we want to save the record into the table by writing

Im trying to build a spring gateway which is getting JWT and is sending the tokens to all underlying services. For this I use the following dependencies:

The dreaded Java SpringBoot app not connecting to MySQL with Docker-compose java.net.ConnectException: Connection refused

Hi Folks,

I have been struggling with the following issue - the dreaded Java SpringBoot app not connecting to MySQL with docker compose exceptions:

com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure

JDBCConnectionException: Unable to open JDBC Connection for DDL execution

java.net.ConnectException: Connection refused

The app works fine on its own, but it can't seem to connect to mysql once I get it in Docker. I am going out of my mind as I think I have all parameters correct, so any help is greatly appreciated! (:

Hello I got a strange issue with a query on Java-springboot.

java.lang.NullPointerException: Cannot invoke "fr.MelodyApp.repository.OrderProductRepository.findByActiveFalse()" because "this.orderProductRepository" is null\

I want to get a list of all OrderProduct Who are still active ! So I have done a query who desperatly return null value. And I don't know why .. I tried with query on SQL it works fine ! I'm asking maybe is due to conversion problem between java and MySQL. I'm looking for some advice ;)

I am looking to setup this project ( https://github.com/afawcett/githubsfdeploy) on my local machine. I'm not too familiar with Java but I feel I've been able to do enough (MAVEN, JAVA environment downloads and system variable settings) to get my windows machine up and running along with Visual Studio Code. I was able to get the spring boot project up and running in visual studio code without any issues so I want to believe I have all the required pieces (https://code.visualstudio.com/docs/java/java-spring-boot).

The spring-boot project has a main method and the one I'm trying to recreate doesn't. I am receiving the error when debugging the githubsfdeploy project that a "main" method could not be found. I've been researching other ways to run a java project without using the main method but haven't recognized the missing piece yet. Would love some direction on what I may not be taking into account. Thanks!
