Parameter 0 of method entityManagerFactory in *.configuration.SecondaryDataSource required a bean of type '*.EntityManagerFactoryBuilder' not be found - spring

Question

I am having 2 database connection scenario, one with neo4j and one with mariadb. so wrote two config class to scan repositories and domain classes but getting below error while starting spring boot application.
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(entityManagerFactoryRef = "barEntityManagerFactory",
transactionManagerRef = "barTransactionManager", basePackages = {"com.nkt.nsw.uiv.uam.foo.repo"})
#Profile("UAM")
public class PrimarydataSource {
#Autowired
private Environment env;
#Bean(name = "barDataSource")
#ConfigurationProperties(prefix = "bar.datasource")
public DataSource dataSource() {
// return DataSourceBuilder.create().build();
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl(env.getProperty("bar.datasource.url"));
dataSource.setDriverClassName(env.getProperty("bar.datasource.driver-class-name"));
dataSource.setUsername(env.getProperty("bar.datasource.username"));
dataSource.setPassword(env.getProperty("bar.datasource.password"));
return dataSource;
}
#Bean(name = "barEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean barEntityManagerFactory(
EntityManagerFactoryBuilder builder, #Qualifier("barDataSource") DataSource dataSource) {
return builder.dataSource(dataSource).packages("com.nkt.nsw.uiv.uam.foo.domain")
.build();
}
#Bean(name = "barTransactionManager")
public PlatformTransactionManager barTransactionManager(
#Qualifier("barEntityManagerFactory") EntityManagerFactory barEntityManagerFactory) {
return new JpaTransactionManager(barEntityManagerFactory);
}
}
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactory",
basePackages = {"com.nkt.nsw.uiv.uam.repository"})
#Profile("UAM")
public class SecondaryDataSource {
#Autowired
private Environment env;
#Primary
#Bean(name = "dataSource")
#ConfigurationProperties(prefix = "spring.data")
public DataSource dataSource() {
// return DataSourceBuilder.create().build();
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl(env.getProperty("spring.data.neo4j.uri"));
// dataSource.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
dataSource.setUsername(env.getProperty("spring.data.neo4j.username"));
dataSource.setPassword(env.getProperty("spring.data.neo4j.password"));
return dataSource;
}
#Primary
#Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
EntityManagerFactoryBuilder builder, #Qualifier("dataSource") DataSource dataSource) {
return builder.dataSource(dataSource).packages("com.nkt.nsw.uiv.uam.entities")
.build();
}
#Primary

Answer 1

Probably you have several configurations and in your #SpringBootApplication you have excluded DataSourceAutoConfigration.class like:
#SpringBootApplication(exclude = {DataSourceAutoConfigration.class})
It is adviced to do because otherwise you get multiple beans of type DataSorce,... on initialization. If that is the case, you can remove the exclusion from
#SpringBootApplication
and mark all the beans in one of your configurations as #Primary, like:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(entityManagerFactoryRef = "barEntityManagerFactory",
transactionManagerRef = "barTransactionManager", basePackages =
{"com.nkt.nsw.uiv.uam.foo.repo"})
#Profile("UAM")
public class PrimarydataSource {
#Primary
#Bean(name = "barDataSource")
...
#Primary
#Bean(name = "entityManagerFactory")
...
}
