Could not autowire. There is more than one bean of 'DataSource' type

Question

I\'m trying to Autowire a database by

@Autowired
private DataSource dataSource;

I have one datasource in my application.yml

Answer 1

I solved by adding qualifier above the property:

@Autowired
@Qualifier("dataSource")
private DataSource dataSource;

Answer 2

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 :)

Please note that Spring Boot autoconfigured beans are not supported 100% yet, see https://youtrack.jetbrains.com/issue/IDEA-139669 for progress and possible workaorunds.
