Spring-boot actuator: only some endpoints work - spring

Question

I'm trying to implement spring-boot actuator for the first time but I've noticed that:
It only works if I specify the version, otherwise not;
Only a few endpoints works among those declared by the /actuator endpoint response.
This is the dependencies I've inserted in my pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
<version>1.4.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator-docs</artifactId>
</dependency>
...
</dependencies>
This is my application.properties:
#info for Spring Boot Actuator
info.app.name=Spring Sample Application
info.app.description=Application to demonstrate Spring REST HATEOAS and Actuator
info.app.version=1.0.0
When I make this http request:
http://localhost:8080/actuator
it returns me:
{"links":[{"rel":"self","href":"http://localhost:8080/actuator"},{"rel":"loggers","href":"http://localhost:8080/loggers"},{"rel":"env","href":"http://localhost:8080/env"},{"rel":"info","href":"http://localhost:8080/info"},{"rel":"heapdump","href":"http://localhost:8080/heapdump"},{"rel":"mappings","href":"http://localhost:8080/mappings"},{"rel":"metrics","href":"http://localhost:8080/metrics"},{"rel":"configprops","href":"http://localhost:8080/configprops"},{"rel":"autoconfig","href":"http://localhost:8080/autoconfig"},{"rel":"beans","href":"http://localhost:8080/beans"},{"rel":"auditevents","href":"http://localhost:8080/auditevents"},{"rel":"trace","href":"http://localhost:8080/trace"},{"rel":"health","href":"http://localhost:8080/health"},{"rel":"dump","href":"http://localhost:8080/dump"},{"rel":"docs","href":"http://localhost:8080/docs"}]}
Among these links, only /health and /info seem to work.
In fact, when I ask for /health it returns:
{"status":"UP"}
When I ask for /info it returnes:
{"app":{"description":"Application to demonstrate Spring REST HATEOAS and Actuator","name":"Spring Sample Application","version":"1.0.0"}}
How comes that all the other endpoints gives me Whitelabel error page?

Answer 1

Did you try to see the logs when you try other endpoints. It says
Full authentication is required to access actuator endpoints. Consider adding Spring Security or set 'management.security.enabled' to false.
I guess this is self explanatory. Configure atleast basic auth or set the above mentioned property to false.
Whitelabel error page that you see also says
There was an unexpected error (type=Unauthorized, status=401).
Here is the link for the doc related to this.

Answer 2

In my case I was getting 404 Whitelabel Error Page because only /actuator/health and /actuator/info are the only endpoints enabled by default (as mentioned on the Spring Boot Actuator documentation)
To enable the other endpoints I ended up adding this configuration to my application.yml:
management:
endpoints:
web:
exposure:
include: info, health, loggers, logfile, configprops

Answer 3

I found a posting at Baeldung where it says
Unlike in previous versions, Actuator comes with most endpoints disabled. (Link)
So add management.endpoints.web.exposure.include=*. to your application.properties.
