sping | Simple example of secured communication | TLS library

I am trying to imitate Spings validated and custom constraints annotations so that I can validate parameters when they reach an endpoint on my server. I got the basics of Proxy and InvocationHandler down, but I am stuck on how a single annotation would execute some code. Take this example:

I want parameters annotated with

My Application is Sping MVC not boot.

I'm using springdoc-openapi-ui 1.4.4

also, I added the following imports to one of my @configuration class;

My project is using spring-boot, sping-data-jpa, spring-data-rest, hibernate

I have updated to spring boot 2.3.1.

My previous test cases are on Junit 4, I am migrating to Junit 5.

When I run my test case with junit 5 it is looking for actual environmental configurations like datasource, hibernate:dialect with Junit 4, it was not looking for it.

Please find Junit 4 and Junit 5 test class for comparison

I have a working embedded H2 database (..mv.db), which I cannot connect to from IntelliJ IDEA.

The credentials are the same as the Spring application.properties which uses it, but from the built-in Database tool in IntelliJ Idea I get this strange error upon connecting (or Testing the connection):

[90062][90062] Error while creating file "C:/Program Files (x86)/IntelliJ IDEA 2020.1.2/bin/data" [90062-200].

I have zero clue how to solve this, couldn't find any resource about this problem. My Sping application connects easily (I shut it down before trying to access the same file).

Materialised fully functional Spring Boot application code from repository and working fine with java 1.8. While upgrading to Java 11 got errors like some packages is accessible from more than one module

1.The package javax.xml.parsers is accessible from more than one module: , java.xml

2.The package org.xml.sax is accessible from more than one module: , java.xml

Tried to resolve the issue by restrict dependency using methods provided in the below links but not helped.

I'm trying to make a simple application with SPing but I keep getting this error and I dont understand why.

I have tried everything, even wre-wrote the whole app. Dont even know what the problem could be.

This is the error I get:

I'm using spring security in my web application the authentication works fine i got redirected to the home page after login , the logged in username is shown in my application and everything is good except for one thing . I have an upload method in my application where the user can upload a video to azure storage and then save the url in the database This is the upload methode

When using the retrieve() method of Spring WebClient in conjunction with bodyToMono default error handling is applied (if the response has status code 4xx or 5xx, the Mono will contain a WebClientException). In error cases the resulting WebClientException is very helpful because it contains the request AND the response, which is very convenient e.g. for logging. Furthermore, I can react to errors very nicely in place.

I am trying to listen to a Solace End Point using Sping Boot and when ran my app i am getting the Error:
