I am new to Spring Security and Oauth2. In my spring boot application, I have implemented authentication with Oauth2 with following set of changes:

Custom Ouath2 User service is as follows:

I'm using spring and want to implement some java-configuration in my application. Here is spring's abstract config, for example

I have looked here here and am unable to get listFiles to work:

I'm trying to generate java code from swagger.json using swagger-codegen-cli.jar but I get this exception:

I am using okta to do authentication. Our company's okta disabled the 'default' authorization server. So right now I cannot use 'okta-spring-security-starter' to simple do this to verify token passed from url headers:

I want to poll for a file in a directory and stop the polling once the file is found. I am very new to Spring framework and a lot of it still is very confusing. After doing some research, I found out a couple of ways of doing this but haven't any luck with any of them.

One of the ways is using a control bus as shown here. However, it just seems that the polling just stops after 2 seconds. I am not sure how to include the condition to stop only when a file is received.

Another way is to use "Smart Polling" as answered here. The link in the answer is old but it points to the official Spring docs here: Smart Polling. Through the article, I learned about AbstractMessageSourceAdvice and SimpleActiveIdleMessageSourceAdvice. The latter seems to suit my goal and would be the simplest to implement, so I decided to give that a go. My codes are as below:

Each row has extra data but I only want the first 3 fields in each row(account name, account number, account domain). The last row has the row count number in each file. Below is a example of file

AWS XRay is a tracing service that allows you to trace requests in distributed systems, and even profile your services. Without going too much in to how XRay works, it basically monitors your service and sends data about each request to the service via UDP to a daemon that collects this data and sends it to AWS.

This daemon, when running locally or in EC2, is local to the machine the service is running on and is available on port 2000. This is the default configuration for the location of the daemon host.

When running in Kubernetes, you need to set up a daemon to run on each node. As per the documentation for setting up XRay with Kubernetes, you can override the default value by setting an environment variable AWS_XRAY_DAEMON_ADDRESS with the required host, or you can set a JVM system variable com.amazonaws.xray.emitters.daemonAddress. There is also a reference to this in the SDK documentation.

Due to my use case, and how we share configurations in my organisation, I would like to utilise the method of setting the environment variable.

As per the documentation, we set it on deployment via our helm charts:
