How to run micrometer elastic with micrometer spring legacy? - spring

Question

im quite new to spring and am trying to connect my application to an elk.
The Application is running spring boot 1.5.5, hence I'm using micrometer legacy.
My pom looks like this:
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-spring-legacy</artifactId>
<version>1.3.9</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-elastic</artifactId>
<version>1.5.1</version>
</dependency>
Whenever I'm trying to start my app I recieve following error:
2020-06-19 13:38:29 [ WARN] Exception encountered during context initialization - cancelling refresh attempt: org.springframework.context.ApplicationContextException: Unable to start embedded containe

The root cause seems to be the class io.micrometer.core.instrument.config.validate.Validated which seems not to be present in the package as it should be.
Any ideas on that?

Answer 1

the root case was a mismatch of the versions o micrometer core which was pulled by other dependencies.
I imported the following
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-spring-legacy</artifactId>
<version>1.3.9</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-elastic</artifactId>
<version>1.5.1</version>
</dependency>
And run into the error above because both dependencies contain a version of micrometer core. In my case version 1.3.9. The needed class was added to micrometer.core with release 1.5.x
So the solution was to define that dependency explicit with version 1.5.x
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-spring-legacy</artifactId>
<version>1.3.9</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-elastic</artifactId>
<version>1.5.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.micrometer/micrometer-core -->
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-core</artifactId>
<version>1.5.1</version>
</dependency>
Anyway the application does not start due to socket timeouts but te error above is fixed. :D
Migration to spring boot 2 might be a faster solution. xD
