Unable to register MBean [HikariDataSource (HikariPool-0)] with key 'dataSource'

Question

I am getting below error in prod mode for (Java8+Oauth2+MySql+Hazelcast+no clustered http sessions) combination. Dev mode has worked fine.

Unable to register MBe         


        

Answer 1

Two things I tried and they worked for deploying two Hikari apps in the same tomcat are: Not only change poolName(1) but also change bean name for DataSource(2) Configuration.

@Bean(destroyMethod = "shutdown")
public DataSource dataSource2() {

    HikariConfig config = new HikariConfig();
    config.setPoolName("AARSHikaripool-1");

Notice bean name is datasource2 while other app has datasource!!

Update for JHipster:

Since there is no datasource bean anymore, in application.yml add the following:

spring:
    jmx:
        default-domain: [application_name]
