Does having spring-boot-actuator changes the context root of the spring application?

Question

According to this post, by having the spring-boot-actuator dependency in pom.xml, I could benefits from the actuator endpoints. However, I observed it breaks my existing my spring application (It is not a spring-boot application).

I added the following to my dependency in pom.xml

      <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-actuator</artifactId>
            <version>1.2.5.RELEASE</version>
       </dependency>

Thats it. I did not make any changes to application yet. I started the container using maven-t7-plugin. Now my application endpoint http://localhost:8010/mycontext/foo is returning 404. I commented out the above dependency in pom.xml. Now my application returns 200 OK for the above request.

Kindly help troubleshoot me as what is going wrong. I could not find any obvious reasons.

Thanks

It shouldn't change the context, rather maybe it somehow expects your page to be in other place? Maybe it enables spring boot web. Show us some code. — ACV, Sep 03 '15 at 20:52
I suspect actuator won't function very well with it not being a spring-boot application. — spencergibb, Sep 03 '15 at 20:53
@ACV. I tried on our production code. I can't share it here. But it is straightforward to test it. meanwhile I will put some simple code here — brain storm, Sep 03 '15 at 21:31
@spencergibb: is it possible it breaks existing application just by having dependency in it? — brain storm, Sep 03 '15 at 21:41
Unless you're component scanning the actuator's packages, just adding it as a dependency to a non-Boot app should have no effect. As ACV said, I think you're going to have to show some code — Andy Wilkinson, Sep 03 '15 at 22:00
@AndyWilkinson: I suppose the problem is from `maven-t7-plugin` — brain storm, Sep 03 '15 at 22:46

When I looked at the spring logs in console, I noticed the following: WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/mycontext/foo] in DispatcherServlet with name 'DispatcherServlet'.

Since I have configured DispatcherServlet in my Spring application, I cannot use auto-configure of spring-boot-actuator.

Once I excluded that dependency, my application works as expected.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-actuator</artifactId>
    <version>1.2.5.RELEASE</version>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId> 
            <artifactId>spring-boot-autoconfigure</artifactId>
        </exclusion>
    </exclusions>
</dependency>
