You specify a couple of properties and suddenly have working database access. Introduction. When configuring H2 we will want the following features: Oracle Compatibility Mode. These configurations are used in the coming sections while configuring entitymanager and transactionmanager for respective DB connections. 2. This allows us to easily get a fully-configured DataSource implementation by default. We can do this by using a configuration class: @Configuration public class TodoDatasourceConfiguration { @Bean @ConfigurationProperties ("spring.datasource.todos") public DataSourceProperties . Indicates that a method produces a bean to be managed by the Spring container. By default, the bean name will be the same as the method name (see bean naming for details on how to customize this behavior). properties : root.prop = xxxx root.prop2 = yyyy root.prop3 = zzzz. By adding spring actuator, we can refresh those beans on the fly. A thread monitors the file changes and makes a call to actuator refresh () method. It is automatically trying to create an instance of DataSourceAutoConfiguration bean and it's failing. setup via the application.properties, in springboot app, the process is automatically, you just configure the database properties and then you can use the JdbcTemplate object The dynamic ways: 2.1 Setup via DataSourceBuilder and application.properties in a @Configuration Bean 2.2 Setup only by DataSourceBuilder, there is no properties file needed @SpringBootApplication public class Application implements CommandLineRunner {. sql. For example: @Bean public MyBean myBean () { // instantiate and configure MyBean obj return obj; } Bean Names Spring Boot uses an opinionated algorithm to scan for and configure a DataSource. Re-binding @ConfigurationProperties does not cover another large class of use cases, where you need more control over the refresh, and where you need a change to . Spring Cloud has also introduced @RefreshScope, and we can use it for configuration classes or beans. I'll assume that Vault is already configured with the Kubernetes Authentication backend. After creating an entity, we need to create a service class. Create datasource bean - In this step, we have created the datasource bean of the spring boot datasource configuration project. @Bean annotation is introduced in Spring framework to avoid XML level configurations. To do so, you need to enable the debug property or enable DEBUG logging for org.springframework.boot.autoconfigure.logging.ConditionEvaluationReportLoggingListener. Spring Actuator provides different endpoints for health, metrics. Configuring datasource <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="$ {db.driver}" /> config; import javax. Configuration; @Configuration public class GeneralServiceClass { @Autowired DataSource dataSource; //TODO public void . (using google's refresh. Configure custom DataSource in Spring Boot. Overview.
