Multitenancy is not working in my JHIpster application - jhipster

Question

I have followed some links to create multi-tenancy in my JHipster application,but its not working.
https://docs.jboss.org/hibernate/orm/current/userguide/html_single/Hibernate_User_Guide.html#multitenacy
https://www.baeldung.com/hibernate-5-multitenancy
https://github.com/jgasmi/jhipster-mt/
I did following:
Added following in my application-dev.yml:
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/myApp?useUnicode=true&characterEncoding=utf8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=UTC&createDatabaseIfNotExist=true
username: root
password: root
serverName: localhost
hikari:
poolName: Hikari
auto-commit: false
data-source-properties:
cachePrepStmts: true
prepStmtCacheSize: 250
prepStmtCacheSqlLimit: 2048
useServerPrepStmts: true
jpa:
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
database: MYSQL
show-sql: true
properties:
hibernate.id.new_generator_mappings: true
hibernate.cache.use_query_cache: false
hibernate.generate_statistics: true
hibernate.cache.use_minimal_puts: true
hibernate.cache.hazelcast.use_lite_member: true
hibernate.tenant_identifier_resolver : com.mycompany.myapp.multitenancy.TenantIdentifierResolver
hibernate.multi_tenant_connection_provider : com.mycompany.myapp.multitenancy.SchemaMultiTenantConnectionProviderImpl
hibernate.multiTenancy : SCHEMA
My TenantIdentifierResolver class:
public class TenantIdentifierResolver implements CurrentTenantIdentifierResolver {
#Override
public String resolveCurrentTenantIdentifier() {
return "myapp2";
}
#Override
public boolean validateExistingCurrentSessions() {
return true;
}
}
And my class SchemaMultiTenantConnectionProviderImpl looks as follows:
public class SchemaMultiTenantConnectionProviderImpl implements MultiTenantConnectionProvider, ServiceRegistryAwareService
{
private final Logger log = LoggerFactory.getLogger(SchemaMultiTenantConnectionProviderImpl.class);
DataSource dataSource;
#Override
public Connection getAnyConnection() throws SQLException {
return this.dataSource.getConnection();
}
#Override
public void releaseAnyConnection(Connection connection) throws SQLException {
try {
connection.createStatement().execute("USE myapp2;");
}
catch (SQLException e) {
throw new HibernateException("Could not alter JDBC connection to specified schema [public]", e);
}
connection.close();
}
#Override
public Connection getConnection(String tenantIdentifier) throws SQLException {
log.warn("Get Connection for Tenatd is:"+tenantIdentifier);
final Connection connection = getAnyConnection();
/*
* try { connection.setCatalog(tenantIdentifier); //
* connection.createStatement().execute("USE " + tenantIdentifier + ";"); //
* connection.setCatalog(tenantIdentifier); //
* connection.setSchema(tenantIdentifier); } catch (SQLException e) { throw new
* HibernateException("Could not alter JDBC connection to specified schema [" +
* tenantIdentifier + "]", e); }
*/
return connection;
}
#Override
public void releaseConnection(String tenantIdentifier, Connection connection) throws SQLException {
// try {
// connection.createStatement().execute("USE "+tenantIdentifier+";");
// }
// catch (SQLException e) {
// throw new HibernateException("Could not alter JDBC connection to specified schema [public]", e);
// }
connection.close();
}
#Override
public boolean supportsAggressiveRelease() {
return false;
}
#Override
public boolean isUnwrappableAs(Class unwrapType) {
return false;
}
#Override
public <T> T unwrap(Class<T> unwrapType) {
return null;
}
#Override
public void injectServices(ServiceRegistryImplementor serviceRegistry) {
Map lSettings = serviceRegistry.getService(ConfigurationService.class).getSettings();
DataSource localDs = (DataSource) lSettings.get("hibernate.connection.datasource");
dataSource = localDs;
}
}
I am just trying to see first that it should work, and then I can change it to be based on tenant logic, schema tenancy logic or database tenancy logic.
When I run the application following is the logs:

Seems like I am missing something small, but not ablw to find it out.
