如何配置和使用两个数据源?

例如,这是我对第一个数据源的需求:

application.properties

#first db
spring.datasource.url = [url]
spring.datasource.username = [username]
spring.datasource.password = [password]
spring.datasource.driverClassName = oracle.jdbc.OracleDriver

#second db ...

应用程序类
@SpringBootApplication
public class SampleApplication
{
    public static void main(String[] args) {
        SpringApplication.run(SampleApplication.class, args);
    }
}

如何修改application.properties以添加另一个数据源?如何自动布线以供其他存储库使用?

最佳答案

干得好。
在您的application.properties文件中添加:

#first db
spring.datasource.url = [url]
spring.datasource.username = [username]
spring.datasource.password = [password]
spring.datasource.driverClassName = oracle.jdbc.OracleDriver

#second db ...
spring.secondDatasource.url = [url]
spring.secondDatasource.username = [username]
spring.secondDatasource.password = [password]
spring.secondDatasource.driverClassName = oracle.jdbc.OracleDriver
在任何用@Configuration注释的类中添加以下方法:
@Bean
@Primary
@ConfigurationProperties(prefix="spring.datasource")
public DataSource primaryDataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
@ConfigurationProperties(prefix="spring.secondDatasource")
public DataSource secondaryDataSource() {
    return DataSourceBuilder.create().build();
}
