spring boot actuator not working on java 6

Question

In java i am trying to setup spring boot actuator in my project. based on the official spring boot website http://docs.spring.io/spring-boot/docs/current/reference/html/ I tried just declaring the actuator dependency. Below is the pom file with the actuator dependency.

When the spring boot service starts up I do not see any http server starting also, when I try accessing default url http: //localhost:8080/info or /health I get connection refused error. Any pointers on what I am missing here ?

Editing my original Questions: Giving more details on why there are so many exclusions

 <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>

The above exclusion is done so that I can use log4j and not the default logback configuration provided by spring boot http: //docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html#howto-configure-log4j-for-logging

<exclusions>
        <exclusion>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-jdbc</artifactId>
        </exclusion>
    </exclusions>

The above one was done so that I can enable HikariCP connection pool rather than tomcat connection pool provided by spring boot http: //stackoverflow.com/a/36287225/1776145

<exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>

The above exclusion is to use jetty in place of tomcat http: //docs.spring.io/spring-boot/docs/current/reference/html/howto-embedded-servlet-containers.html#howto-use-jetty-instead-of-tomcat

<exclusions>
        <exclusion>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-commons</artifactId>
        </exclusion>
</exclusions>

The above exclusion is done as it was giving unsupported major minor error as I am using Java 6

The given POM is absolutely messy. Do not include Spring libs yourself, do it using the boot starters. Also, the spring boot maven plugin itself should be enough in your build part. Also, try to avoid exclusions in the starter dependencies. — Aritz, Jul 03 '16 at 20:14

Please change the pom.xml and try this. Yes I agree I trimmed exclusion dependencies. This is the basic example for acutator health check from Spring boot.

Request to remove the version tag , which is not required for Spring boot applications

org.springframework.boot spring-boot-starter-parent 1.3.5.RELEASE — Pavan, Jul 04 '16 at 06:30
@M. Deinum after adding the above changes it's causing java.lang.UnsupportedClassVersionError: javax/annotation/ManagedBean : Unsupported major.minor version 51.0 — Deepak Pandey, Jul 04 '16 at 17:05
I have convinced my Project Manager to use Java 8 now. Thank you for your valuable comments. I will fix my pom file now. — Deepak Pandey, Jul 04 '16 at 17:09
