I'm trying to Autowire a database by
@Autowired
private DataSource dataSource;
I have one datasource in my application.yml
spring:
profiles:
active: dev
---
spring:
profiles: dev
datasource:
driverClassName: org.mariadb.jdbc.Driver
url: jdbc:mariadb://localhost:3306/dbname
username: user
password: password
name: dev
logging:
level:
org.springframework: INFO
---
spring:
profiles: prod
name: prod
logging:
level:
org.springframework: INFO
But I get an error message saying.
Could not autowire. There is more than one bean of 'DataSource' type.
Beans:dataSource (DataSourceConfiguration.class)
dataSource (DataSourceConfiguration.class)
Which I find strange since I only have one datasource defined in my application.yml
and to my knowledge I don't have any other datasource defined.
I gave a try with a config but I still get the same issue.
@Configuration
@EnableConfigurationProperties
public class AppConfig {
@Bean
@ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
}
This is my 'pom' file

I'm using Spring Boot 1.5.2 and IntelliJ 2017.1
Try this it worked for me, use @Primary like this
@Primary
@Bean(name ="prodDataSource")
@ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "prodJdbc")
public JdbcTemplate prodJdbcTemplate(@Qualifier("prodDataSource") DataSource prodDataSource){
return new JdbcTemplate(prodJdbcTemplate);
}
@Bean(name = "devDataSource")
@ConfigurationProperties(prefix = "spring.datasource.dev")
public DataSource devDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "devJdbc")
public JdbcTemplate devJdbcTemplate(@Qualifier("devDataSource") DataSource devDataSource) {
return new JdbcTemplate(devDataSource);
}
And then use @autowire like this
@Autowired
@Qualifier("prodJdbc")
private JdbcTemplate prodJdbcTemplate;
I hope this can help you or someone else :)
