具体是init()中基于类型获取dataSource的原因：

    @PostConstruct

    public void init() {

        if (!this.properties.isInitialize()) {

            logger.debug("Initialization disabled (not running DDL scripts)");

            return;

        }

        if (this.applicationContext.getBeanNamesForType(DataSource.class, false,

                false).length > 0) {

            this.dataSource = this.applicationContext.getBean(DataSource.class);

        }

        if (this.dataSource == null) {

            logger.debug("No DataSource found so not initializing");

            return;

        }

        runSchemaScripts();

    }
