Creating Bean HikariDataSource

    @Primary
    @Bean(name = "dataSourceBase", destroyMethod = "close")
    public HikariDataSource hikarDataSource(HikariConfig hikariConfigDataSource){
        HikariDataSource hikariDataSource = new HikariDataSource(hikariConfigDataSource);

Creating Bean DBAccessListener

@Bean(name = "dbAccessListener")
public DBAccessListener DBAccessListener(DatoFeatureFlagService datoFeatureFlagService) {
    DBAccessListener dbAccessListener = new DBAccessListener(datoFeatureFlagService);
    return dbAccessListener;

public ChainListener queryListener(DBAccessListener dbAccessListener) {
    ChainListener queryListener = new ChainListener();
    queryListener.addListener(dbAccessListener);
    return queryListener;
}

Creating Bean ProxyConfigSpringXmlSupport

@Bean(name = "proxyConfigSupport")
public ProxyConfigSpringXmlSupport proxyDataSourceSupport(ChainListener queryListener) {
    ProxyConfigSpringXmlSupport proxyConfigSpringXmlSupport = new ProxyConfigSpringXmlSupport();
    proxyConfigSpringXmlSupport.setDataSourceName("dataSourceDefaultName");
    proxyConfigSpringXmlSupport.setQueryListener(queryListener);
    return proxyConfigSpringXmlSupport;
}

Creating Bean ProxyConfig

    @Bean(name = "proxyConfig")
    public ProxyConfig proxyConfig(ProxyConfigSpringXmlSupport proxyConfigSpringXmlSupport) {
        return proxyConfigSpringXmlSupport.create();

    }



    @Bean(name = "dataSource")
    public ProxyDataSource proxyDataSource(HikariDataSource hikariDataSource, ProxyConfig proxyConfig){
        ProxyDataSource proxyDataSource = new ProxyDataSource();
        proxyDataSource.setDataSource(hikariDataSource);

}
