Unable to register MBe         


        

Answer 1

The following approach worked for me, randomize the pool name jmx domain (spring.jmx.default-domain)(please see JmxAutoConfiguration) :

@Bean
public DataSource dataSource() throws SQLException {
    HikariDataSource dataSource = new HikariDataSource(this);
    dataSource.setPoolName("dataSource_" + UUID.randomUUID().toString());
    return dataSource;
}

@Bean
@ConditionalOnMissingBean(value = ObjectNamingStrategy.class, search = SearchStrategy.CURRENT)
public ParentAwareNamingStrategy objectNamingStrategy() {
    ParentAwareNamingStrategy namingStrategy = new ParentAwareNamingStrategy(new AnnotationJmxAttributeSource());
    namingStrategy.setDefaultDomain("domain_" + UUID.randomUUID().toString());
    return namingStrategy;
}
