Я настроил мое веб-приложение с весенней загрузкой 2 с несколькими источниками данных, h2 и mysql с источником данных h2 в качестве основного.
В моем src / main / resources есть сценарии schema.sql и data.sql, которые обрабатываются как mysql, так и h2 во время запуска приложения.
Сценарии schema-h2.sql и data-h2.sql содержат коды, специфичные для h2, которые работали нормально, когда в моем приложении был настроен только один источник данныхкак h2.
Ниже приведены мои классы конфигурации и свойства.
Какие изменения я должен сделать, чтобы Spring мог использовать h2 только для выполнения сценариев, а не mysql?
application.properties:
spring.h2.console.enabled=true
logging.file=staging-app.log
logging.level.web=trace
spring.mvc.view.prefix=/static/
spring.mvc.view.suffix=.html
spring.datasource.url=jdbc:h2:mem:stagingdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.initialization-mode=always
#spring.datasource.platform=h2
#spring.datasource.continue-on-error=true
#spring.datasource.initialize=false
powerplan.datasource.jdbc-url=jdbc:mysql://localhost:3306/mmc
powerplan.datasource.driverClassName=com.mysql.cj.jdbc.Driver
powerplan.datasource.username=root
powerplan.datasource.password=admin
powerplan.datasource.initialization-mode=never
powerplan.datasource.initialize=false
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=none
spring.jpa.open-in-view=false
Конфигурация компонента источника данных:
@Bean("h2Datasource")
@Primary
@ConfigurationProperties(prefix = "spring.datasource")
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
@Bean("mysqlDatasource")
@ConfigurationProperties(prefix = "powerplan.datasource")
public HikariDataSource dataSource(DataSourceProperties properties) {
return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
.build();
}
