Spring-boot 3 onfig server client tries localhost:8888 even if URLs are properly configured

The same question has been asked in stack-overflow, but no proper solution was been found. I have the following configurations in my app. It complains about the same issue and even it stuck, if some other app runs on 8888.

Does any body has answers to avoid this?

Solution

You're using spring-cloud-starter-bootstrap, which enables legacy configuration processing. However, in your properties you're using the new way of configuring the configuration processing.

So you have two choices:

Remove spring-cloud-starter-bootstrap.
Use the legacy configuration processing, which means you need to create a bootstrap.properties or bootstrap.yml file containing:
```
spring:
  application:
    name: my-app
  cloud:
    config:
      uri: http://myconfig:5232
```
