Spring Boot 配置和使用两个数据源

问题描述

如何配置和使用两个数据源?

How can I configure and use two data sources?

例如，这是我对第一个数据源所拥有的:

For example here is what I have for the first data source:

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?我如何自动装配它以供不同的存储库使用?

How do I modify application.properties to add another data source? How do I autowire it to be used by a different repository?

推荐答案

给你.

在您的 application.properties 文件中添加:

Add in your application.properties file:

#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注解的类中添加以下方法:

Add in any class annotated with @Configuration the following methods:

@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();
}
