Multiple Spring-boot applications running on one Tomcat

Question

Can I have two (or more) Spring-boot applications running on one Tomcat?

I have two applications packaged as war files and I would like to run them on one Tomcat server. However, when I deploy them, I get the following exception:

org.springframework.jmx.export.UnableToRegisterMBeanException: 
    Unable to register MBean [org.springframework.boot.actuate.endpoint.jmx.DataEndpointMBean@2361d8ee] with key 'dumpEndpoint'; 
    nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Endpoint,name=dumpEndpoint

The default endpoints that every Spring-boot application registers (like /health etc.) clash. Is there some workaround for this or is not possible to achieve this setup?

Thank you for any responses!

As Spring Boot Reference says:

If your application contains more than one Spring ApplicationContext you may find that names clash. To solve this problem you can set the endpoints.jmx.uniqueNames property to true so that MBean names are always unique.

endpoints.jmx.domain=myapp
endpoints.jmx.uniqueNames=true

I have two spring boot application deployed on same tomcat and both application have same datasource. I get InstanceAlreadyExistsException: org.apache.tomcat.jdbc.pool.jmx:name=dataSourceMBean,type=ConnectionPool . I have already set endpoints.jmx.domain=myapp endpoints.jmx.uniqueNames=true. But I still get the error. Any suggestions – Mukun Oct 21 '16 at 04:46
@Mukun were you able to figure this out? – i_raqz Aug 20 '17 at 05:07

Similar to @Maciej answer. An alternative is to set the following

spring.application.name=my-app-name
spring.jmx.default-domain=my-app-name

Or for application.yaml:

spring:
  application:
    name: my-app-name
  jmx:
    default-domain: my-app-name

Worked for me on Spring boot 1.5.9.RELEASE
