Hoc signum est exemplum utendi piscinæ ver Tabernis et druidis connexionis ad connexionem datorum Hive configurandi.Ostendit quomodo fiet@ConfigurationPropertiesAnnotationes ad simpliciorem ligationem proprietatum conformationis et quomodo utendi ver@BeanAnnotationes creare et administrareDataSourceetJdbcTemplate Fabri. Haec explicatio accurata huius codicis doctrina est:

1. @ConfigurationProperties(prefix = "hive")

• effectus: Haec annotationem limam configurationem addere (utapplication.propertiesor *application.yml) In praepositione esthiveProprietates eorum obligantur ad classem hodiernam (HiveDruidConfig ) agrum. Hoc facit nexus configurans datorum aliosque parametros relatos valde opportunos et centrales.
• exemplum: Si tu esapplication.propertiesesthive.url=jdbc:hive2://...,Sourlager statim datus est pretii.

2. @Data

• effectus : Haec annotationis ex bibliotheca Lombok venit, quae sponte getter, novos, pares, hashCode et modos camporum classium generat. Hoc codicem boilerplate minuit, et genera mundiorem facit.

3. ager definition

• Multiplicia privata agri in genere definiuntur, quae configurationi parametri Alvei database nexu et nexu piscinae druidae respondent.

4. dataSource()methodo

• effectus: Hic modus utitur@Bean Annotatione, significans Bean rediturum, quae a vase Verno agetur.In hoc exemplo a . creat et conformatDruidDataSourceExempli gratia, haec nexus piscinae druidae exsecutio est.
• Configurationis: Variae proprietates DruidDataSource per methodum novorum intra modum positae sunt. Hae proprietates ex valoribus classium agrorum veniunt, et hae valores transeunt@ConfigurationPropertiesEx configuratione lima.
• reditus valorem: Modus figuram refertDruidDataSourceexempli gratia, continens fons eam subcriptio pro instantia nominatahiveDruidDataSourceFabri.

5. hiveDruidTemplate()methodo

• effectus: Hic modus etiam usus est@Beanannotationem, quae creat aSJdbcTemplateExempli gratia, hoc instantia adhibetur ad operationes datorum simpliciores reddendas.
• modulus: Modus accipit aDataSourcetypus ambitum transierunt@Qualifier("hiveDruidDataSource")Determinatur annotationis nomen utenshiveDruidDataSourceDataSource Bean.
• reditus valorem: Modus figuram refertJdbcTemplateexempli gratia, continens fons eam subcriptio pro instantia nominatahiveDruidTemplateFabri.

Summatim

Hoc signum quomodo fiet@ConfigurationPropertieset@Bean Annotationes ad nexus database configurare et administrare. Utendo nexu piscinae Druidicae, effectio et stabilitas operationum datorum amplius emendari potest.Simul, perJdbcTemplate, tincidunt operationes datorum commodius conficere possunt sine magna copia codicis JDBC scribentis.
