我有兩個spring-boot應用程序。應用程序A正在使用使用HikariDataSource數據源配置的MySQL數據庫。應用程序B正在使用使用tomcat數據源配置的SQL Server數據庫。在啓動spring-boot時，tomcat datasource沒有檢查有效連接？
當我爲數據庫參數提供錯誤的用戶名時，應用程序A無法啓動並出現以下異常錯誤。然而，應用程序B啓動正常，但是當我使用數據源進行服務調用時，會拋出錯誤。爲什麼數據源連接檢查在後者中被忽略？
注意：我有另一個彈簧應用程序（應用程序C），它使用tomcat數據源連接到SQL SERVER，並在容器啓動時出錯，如果提供了錯誤的憑據。這不是一個彈簧啓動應用程序，雖然
這裏是我的應用程序數據源配置
@Bean
public DataSource dataSource() {
HikariDataSource dataSource = new HikariDataSource();
dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driver"));
dataSource.setJdbcUrl(environment.getRequiredProperty("jdbc.url"));
dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return dataSource;
}
應用B數據源配置
import org.apache.tomcat.jdbc.pool.DataSource;
@Bean
public DataSource datasource() {
DataSource ds = new DataSource();
ds.setDriverClassName(hostdb_driver);
ds.setUrl(hostdb_url);
ds.setUsername(hostdb_user);
ds.setPassword(pass);
ds.setMaxActive(hostdb_maxActive);
ds.setMaxIdle(hostdb_maxIdle);
ds.setInitialSize(hostdb_initialSize);
ds.setMinIdle(hostdb_minIdle);
ds.setTestOnBorrow(hostdb_testOnBorrow);
ds.setTestWhileIdle(hostdb_testWhileIdle);
ds.setValidationQuery(hostdb_validationQuery);
ds.setRemoveAbandoned(hostdb_removeAbandoned);
ds.setRemoveAbandonedTimeout(hostdb_removeAbandonedTimeout);
ds.setLogAbandoned(hostdb_logAbandoned);
ds.setValidationInterval(hostdb_validationInterval);
return ds;
}

故障出現在應用程序A發生的事情，因爲Hibernate的配置是它的初始化過程中進行的數據庫調用的代碼。應用程序B是否也使用Hibernate？ –
@AndyWilkinson：你怎麼說應用程序A在初始化過程中使用hibernate。你是對的，應用程序A使用休眠。但錯誤日誌不顯示任何休眠相關的數據庫初始化。 –
Spring Boot的JPA/Hibernate自動配置正在進行JDBC調用，作爲確定數據庫的默認DDL自動行爲的一部分。 –
