Spring boot cannot start with two or more DataSources

[quaso]

DataSourceInitializer init method fails, because it works only if there is just one DataSource bean in the context>

if (this.applicationContext.getBeanNamesForType(DataSource.class, false, false).length > 0) { this.dataSource = this.applicationContext.getBean(DataSource.class); }

Either change condition in if clause to "== 0" or handle org.springframework.beans.factory.NoUniqueBeanDefinitionException prope

Found workaround solution - exlude autoconfiguration of Datasources:

@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class })

I'm pleased to hear that you've found a workaround. An alternative that you might like to consider is to mark one of your DataSource beans as @Primary.

Also, you may be interested to know that the general situation will improve in 1.4.0.M2 when #2784 is implemented. It will mean that the initialiser backs off when there are multiple DataSource beans to choose from rather than failing as it currently does.
