我有一个 Spring Boot 2 应用程序,它使用两个数据源 - 一个 Oracle 和一个 H2。 H2 数据源设置为辅助数据源,我想在启动时为其创建架构,但它永远不会触发 schema.sql 文件。这是我的数据源配置文件:
@Configuration
public class DataSourceConfig {
@Bean
@Primary
@ConfigurationProperties("spring.datasource")
public DataSourceProperties primaryDataSourceProperties() {
return new DataSourceProperties();
}
@Bean
@Primary
@ConfigurationProperties("spring.datasource")
public DataSource primaryDataSource() {
return primaryDataSourceProperties().initializeDataSourceBuilder().build();
}
@Bean
@ConfigurationProperties("spring.runlogdatasource")
public DataSourceProperties runlogDataSourceProperties() {
return new DataSourceProperties();
}
@Bean
@ConfigurationProperties("spring.runlogdatasource")
public DataSource runlogDataSource() {
return runlogDataSourceProperties().initializeDataSourceBuilder().build();
}
}
这是我的 application.properties 文件:
spring.datasource.url=jdbc:oracle:thin:@my.database.com:1521/mydb
spring.datasource.username=test
spring.datasource.password=ENC(3PXcnoBndLpWN1EcMtmIn+odOwhdWjSrqANijutxuekKEIOco64Jew==)
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.initialization-mode=never
spring.datasource.hikari.connection-timeout=60000
spring.datasource.hikari.maximum-pool-size=10
jasypt.encryptor.bean=stringEncryptor
spring.runlogdatasource.url=jdbc:h2:~/runlogdb;CIPHER=AES;DB_CLOSE_ON_EXIT=FALSE;
spring.runlogdatasource.username=sa
spring.runlogdatasource.password=ENC(3PXcnoBndLpWN1EcMtmIn+odOwhdWjSrqANijutxuekKEIOco64Jew==)
spring.runlogdatasource.driverClassName=org.h2.Driver
spring.runlogdatasource.platform=h2
spring.runlogdatasource.schema=classpath:schema-h2.sql
对于主数据源,我可以看到它进入了 DataSourceInitializerInvoker,这是它尝试加载架构的地方,但由于没有 schema-all.sql 文件,它跳过了那个文件。但是,我确实有一个 schema-h2.sql 文件,但是对于辅助数据源,它从不进入 DataSourceInitializerInvoker,因此从不尝试初始化架构。任何帮助将不胜感激!
最佳答案
这是预期的行为。指定主数据源时,仅执行此数据源的架构和数据。为了获得这种行为,您需要做的是为两个数据源中的每一个定义 DataSourceInitializer
。
@Bean
public DataSourceInitializer dataSourceInitializer1(@Qualifier("datasource1") DataSource datasource) {
ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
resourceDatabasePopulator.addScript(new ClassPathResource("schema-h22.sql"));
resourceDatabasePopulator.addScript(new ClassPathResource("data-h22.sql"));
DataSourceInitializer dataSourceInitializer = new DataSourceInitializer();
dataSourceInitializer.setDataSource(datasource);
dataSourceInitializer.setDatabasePopulator(resourceDatabasePopulator);
return dataSourceInitializer;
}
@Bean
public DataSourceInitializer dataSourceInitializer2(@Qualifier("datasource2") DataSource datasource) {
ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
resourceDatabasePopulator.addScript(new ClassPathResource("schema-h21.sql"));
resourceDatabasePopulator.addScript(new ClassPathResource("data-h21.sql"));
DataSourceInitializer dataSourceInitializer = new DataSourceInitializer();
dataSourceInitializer.setDataSource(datasource);
dataSourceInitializer.setDatabasePopulator(resourceDatabasePopulator);
return dataSourceInitializer;
}
您还需要禁用默认的spring数据初始化。你可以通过
spring.datasource.initialization-mode=never
