If you use “Spring Security” sensitive endpoints will be exposed over HTTP, but also protected. By default “basic” authentication will be used with the username user and a generated password (which is printed on the console when the application starts).

You can use Spring properties to change the username and passsword and to change the security role required to access the endpoints. For example, you might set the following in your application.properties:

security.user.name=admin
security.user.password=secret
management.security.role=SUPERUSER

Sometimes it is useful to group all management endpoints under a single path. For example, your application might already use /info for another purpose. You can use the management.contextPath property to set a prefix for your manangement endpoint:

management.context-path=/manage

The application.properties example above will change the endpoint from /{id} to /manage/{id} (e.g. /manage/info).

Exposing management endpoints using the default HTTP port is a sensible choice for cloud based deployments. If, however, your application runs inside your own data center you may prefer to expose endpoints using a different HTTP port.

The management.port property can be used to change the HTTP port.

management.port=8081

Since your management port is often protected by a firewall, and not exposed to the public you might not need security on the management endpoints, even if your main application is secure. In that case you will have Spring Security on the classpath, and you can disable management security like this:

management.security.enabled=false

(If you don’t have Spring Security on the classpath then there is no need to explicitly disable the management security in this way, and it might even break the application.)

You can customize the address that the management endpoints are available on by setting the management.address property. This can be useful if you want to listen only on an internal or ops-facing network, or to only listen for connections from localhost.

Here is an example application.properties that will not allow remote management connections:

management.port=8081
management.address=127.0.0.1

If you don’t want to expose endpoints over HTTP you can set the management port to -1:

management.port=-1
