Multiple DataSource beans with Spring Boot Actuator's EndpointAutoConfiguration possible?

Question

I have a spring-boot application that uses several DataSource beans and would still like to use the EndpointAutoConfiguration from spring-boot-actuator that is loaded as part of using the @EnableAutoConfiguration annotation. This doesn't seem possible as there is a DataSource bean injected into EndpointAutoConfiguration to setup the HealthEndpoint bean. Due to the multiple instances of DataSource that exist in my application, a NoUniqueBeanDefinitionException is thrown upon application startup unless I exclude EndpointAutoConfiguration but then I must setup all the other endpoints manually (/env, /metrics, etc).

Is there a better way to do this?

Answer 1

You could mark one of your DataSources as @Primary or you could provide your own HealthIndicator (it's not the endpoint that wants your DataSource but that bean, which is designed to be overridden by just adding one of your own).
