Getting a signing page when visiting localhost 8080 - spring-boot

I am trying to create a simple web app using spring boot in eclipse. I have created a new spring starter project and run it in eclipse.it works very well.
but when I go to the localhost 8080 pages, I am getting a sign-in page.
I have no security dependencies in my pom.xml
even if I tried to go to localhost without running my app same problem
my pom.xml

You can try by clearing the cache and then submitting a new request.

Spring Boot Why are my changes to the application.properties not being saved?

I have a test Spring project in which I have a few routes mapped to the views from the controllers, my problem is that every time I close or execute a change in my project the port is changed to 8080 (Spring default port) , but I already occupy that port and I need to use 8081
When I write:
server.port=8081

in my application.properties the port changes correctly, until I make and save a change to the models or source code. How do I fix this?

Spring Security Authorization Server (experimental) - Sample projects, from Gradle to Maven (Dependencies)

As recommended here I now want to try the sample projects given in the experimental Authorization Server project.
I use Maven, don't know much about Gradle. I assume, that the samples folder is independent of any other artifact in the Authorization Server project?
I created via start.spring.io the 3 projects, added the missing dependencies manually, and the pom.xml look like this:

Are these pom.xml correct? Is anything missing, are the versions OK to use, etc.?
I want to change my webservice (Spring Boot, REST controllers) from Basic Auth to OAuth2. My webservice is build with Spring Boot 2.5.3 and OpenJDK 15 (might change to 16) and Maven. That's why I use the latest versions in the pom.xml. But sample projects don't specify versions or use older version, that's why I don't know what versions are OK to use.
Is auth-server necessary or can it be replaced with 127.0.0.1?
AS
return new ProviderSettings().issuer("http://auth-server:9000")
->
return new ProviderSettings().issuer("http://127.0.0.1:9000")
RS
issuer-uri: http://auth-server:9000
->
issuer-uri: http://127.0.0.1:9000
Client
issuer-uri: http://auth-server:9000
->
issuer-uri: http://127.0.0.1:9000
Also, at https://github.com/spring-projects-experimental/spring-authorization-server/tree/main/samples/boot/oauth2-integration there are 4 projects.
The README says
Run Authorization Server
Run Resource Server
Run Client
what for is the project authorizationserver-custom-consent-page ?
I'm asking about the versions I use, latest in fact, because for example I need OpenJDK 15 as I'm using """ all over the place in my webservice project (which will be the Resource Server in context of OAuth2). I cannot therefore switch to versions like Java 8 or so, as stated here:
Prerequisites
Git and the JDK8 build.
Be sure that your JAVA_HOME environment variable points to the jdk1.8.0 folder extracted from the JDK download.
I'm not sure if my problems are related to newer versions of dependencies I use.
Meanwhile, with Maven all 3 projects compile and start, but I'm stuck at the login page. After giving the username and password, it remains on the login page. It seems to accept the user credentials, but loads the login page again. If I misspell the username or password, it complains bad credentials. This is with samples from the downloaded sources of 0.1.2.
It is not stated why auth-server has to be used, and therefore I did the replacements described earlier.
What value will be replaced for registrationId in redirect-uri: "http://127.0.0.1:8080/login/oauth2/code/{registrationId}" ?

How to configure JWT authentication in springboot 2.2.7? Unable to extend WebSecurityConfigurerAdaptor

WebSecurityConfigurerAdapter is not available in Spring Boot 2.2.7 . I get WebSecurityEnablerConfiguration but could not find an example on how to work with this. I need to override the configure method which is available in WebSecurityConfigurerAdapter. How to get this class or is there any workaround?
I have initialised the project using Spring Initializr and trying to establish a basic JWT authorisation.

I can't get springboot devtools to work

I'm using STS 3.8.4, I've placed the spring devtools dependency on my pom.xml, I tried to run my springboot project on the IDE, went to a page (template using thymeleaf) and tried to modify something on the template, I hit refresh but nothing happens. Is there any other configuration needed? I also tried setting thymeleaf caching to false but still no luck. Below is my pom.xml.

I finally found the solution. The problem was my eclipse is not automatically building the project upon saving.

Odd behavior when switching spring-boot-starter-web for spring-boot-starter-jersey

As per the documentation I'd expect that I can swap spring-boot-starter-web for spring-boot-starter-jetty and all my rest controllers should work as before. Strange enough, after doing this, not a single controller is mapped, not even those from the actuator starter.
