I'm running a Spring Boot 2.6.13 app with spring-boot-actuators, and I'm trying to set the management port via config tree. This gives the following error (full stacktrace at the end):
Caused by: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [org.springframework.boot.env.ConfigTreePropertySource$PropertyFileContent] to type [java.lang.Integer]
The issue seems very similar to https://github.com/spring-projects/spring-boot/issues/24171, but the fix for that appears to not affect the management port.
Steps to reproduce:
1. Use start.spring.io to make a 2.6.13 app with Spring Boot Actuator and Spring Web dependencies
2. echo 'spring.config.import=configtree:/tmp/config/' >> src/main/resources/application.properties
3. mkdir -p /tmp/config/management/server
4. echo 8081 > /tmp/config/management/server/port
5. ./gradlew bootRun # this fails
This issue does not appear if you try to set server.port instead. Interestingly, if you set server.port and management.server.port both to the same value, the issue does not appear either.
