I have multiple database connections with named EntityManagers:
#Bean(name = "integDB")
#Primary
#ConfigurationProperties(prefix="spring.datasource")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
#Bean(name = "integEM")
public LocalContainerEntityManagerFactoryBean integDbEntityManagerFactory(EntityManagerFactoryBuilder builder) {
....
}
How do I specify which entity manager to use here?
#Repository
public interface IntControleFilaRepository extends JpaRepository<IntControleFilaEntity, String> {
}
Spring is complaining about it:
Parameter 0 of constructor in ... required a bean named 'entityManagerFactory' that could not be found.
Create a configuration class for each database and specify the entityManager associated with each one:
#Configuration
#EnableJpaRepositories(basePackages = {"..."}, entityManagerFactoryRef = "integEM", transactionManagerRef = "integTM")
public class IntegReposConfig {
}

I am using Spring boot(2.3.5), Oracle19c DB, and Hibernate(5.4).
I tried to make multi-datasource connection, but I keep getting a dialect error Couldn't determine Dialect for "oracle".
Error creating bean with name 'jdbcDialect' defined in class path resource [org/springframework/boot/autoconfigure/data/jdbc/JdbcRepositoriesAutoConfiguration$SpringBootJdbcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.relational.core.dialect.Dialect]: Factory method 'jdbcDialect' threw exception; nested exception is org.springframework.data.jdbc.repository.config.DialectResolver$NoDialectException: Cannot determine a dialect for org.springframework.jdbc.core.JdbcTemplate#2ba9ed19. Please provide a Dialect.
I basically followed this tutorial to configure multiple data sources.
application.properties:
spring.datasource-primary.username=oracleprimary
spring.datasource-primary.password=oracleprimary
spring.datasource-primary.url=jdbc:oracle:thin:#//localhost:1521/orcl
spring.datasource-secondary.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource-secondary.username=oraclesecondary
spring.datasource-secondary.password=oraclesecondary
spring.datasource-secondary.url=jdbc:oracle:thin:#//localhost:1521/orcl
Primary configuration:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "primaryEntityManagerFactory",
transactionManagerRef = "primaryTransactionManager",
basePackages = {"com.foo.primary.repository"})
public class PrimaryDataSourceConfiguration {
#Primary
#Bean(name = "primaryDataSourceProperties")
#ConfigurationProperties("spring.datasource-primary")
public DataSourceProperties primaryDataSourceProperties() {
return new DataSourceProperties();
}
#Primary
#Bean(name = "primaryDataSource")
#ConfigurationProperties("spring.datasource-primary.configuration")
public DataSource primaryDataSource(#Qualifier("primaryDataSourceProperties") DataSourceProperties primaryDataSourceProperties) {
return primaryDataSourceProperties.initializeDataSourceBuilder().type(HikariDataSource.class).build();
}
#Primary
#Bean(name = "primaryEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory(
EntityManagerFactoryBuilder primaryEntityManagerFactoryBuilder, #Qualifier("primaryDataSource") DataSource primaryDataSource) {
Map<String, String> primaryJpaProperties = new HashMap<>();
primaryJpaProperties.put("hibernate.dialect", "org.hibernate.dialect.Oracle12cDialect");
return primaryEntityManagerFactoryBuilder
.dataSource(primaryDataSource)
.packages("com.foo.primary.model")
.persistenceUnit("primaryDataSource")
.properties(primaryJpaProperties)
.build();
}
#Primary
#Bean(name = "primaryTransactionManager")
public PlatformTransactionManager primaryTransactionManager(
#Qualifier("primaryEntityManagerFactory") EntityManagerFactory primaryEntityManagerFactory) {
return new JpaTransactionManager(primaryEntityManagerFactory);
}
Second configuration:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "secondaryEntityManagerFactory",
transactionManagerRef = "secondaryTransactionManager",
basePackages = {"com.foo.secondary.repository"})
public class SecondaryDataSourceConfiguration {
#Bean(name = "secondaryDataSourceProperties")
#ConfigurationProperties("spring.datasource-secondary")
public DataSourceProperties secondaryDataSourceProperties() {
return new DataSourceProperties();
}
#Bean(name = "secondaryDataSource")
#ConfigurationProperties("spring.datasource-secondary.configuration")
public DataSource secondaryDataSource(#Qualifier("secondaryDataSourceProperties") DataSourceProperties secondaryDataSourceProperties) {
return secondaryDataSourceProperties.initializeDataSourceBuilder().type(HikariDataSource.class).build();
}
#Bean(name = "secondaryEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean secondaryEntityManagerFactory(
EntityManagerFactoryBuilder secondaryEntityManagerFactoryBuilder, #Qualifier("secondaryDataSource") DataSource secondaryDataSource) {
Map<String, String> secondaryJpaProperties = new HashMap<>();
secondaryJpaProperties.put("hibernate.dialect", "org.hibernate.dialect.Oracle12cDialect");
return secondaryEntityManagerFactoryBuilder
.dataSource(secondaryDataSource)
.packages("com.foo.secondary.model")
.persistenceUnit("secondaryDataSource")
.properties(secondaryJpaProperties)
.build();
}
#Bean(name = "secondaryTransactionManager")
public PlatformTransactionManager secondaryTransactionManager(
#Qualifier("secondaryEntityManagerFactory") EntityManagerFactory secondaryEntityManagerFactory) {
return new JpaTransactionManager(secondaryEntityManagerFactory);
}
}
I also tried org.hibernate.dialect.Oracle10gDialect, and set spring.jpa.database-platform=org.hibernate.dialect.Oracle12cDialect in application.properties, but nothing changed.
How can I properly configure dialect for oracle?
Spring Data JDBC does not support oracle dialect. You need to define your dialect that implements JdbcDialectProvider.
public final class OracleDialect implements DialectResolver.JdbcDialectProvider {
private static Dialect getDialect(Connection connection) throws SQLException {
DatabaseMetaData metaData = connection.getMetaData();
String name = metaData.getDatabaseProductName().toLowerCase(Locale.ROOT);
if (name.contains("oracle")) {
return AnsiDialect.INSTANCE;
}
return null;
}
#Override
public Optional<Dialect> getDialect(JdbcOperations operations) {
return Optional.ofNullable(operations.execute((ConnectionCallback<Dialect>) OracleDialect::getDialect));
}
}
Add spring-boot-starter-data-jdbc dependency in your build.gradle or pom.xml.
Then, as mentioned in the blog, create spring.factories file in resources/META-INF, and paste the following command:
org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=<your-package>.OracleDialect
Also, since both databases you use are the same (OracleDB), you do not need to set .properties() for entity manager. As #SternK mentioned, you can have spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle12cDialect in your application.properties only.
I am using Spring JPA Repository to connect to Oracle.
My Repository package is com.demo.infrastructure.repository;
Repository class is StoreRepo.java
#Repository
public interface StoreRepo extends JpaRepository<StoreAttribute, String> {
#Query("select storeAttributeName from StoreAttribute order by storeAttributeName asc")
List<String> fetchAllStoreAttributeNames();
List<StoreAttribute> findAllByOrderByStoreAttributeNameAsc();
}
Problem:
I am using JNDI config to configure data source. Currently it has only one JNDI entry. Now I want to use two user names for the same database, one with admin(read-write) access and the other with user(read-only) access. Both these users will access the same Repository and same entity.
I tried the solutions already available which uses two different repository packages for each data source. But I want the Repository "StoreRepo" to be the same.
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactoryAdmin",
basePackages = { "com.demo.infrastructure.repository" }
)
public class DataSourceAdminConfig {
#Primary
#Bean(name = "dataSourceAdmin")
public DataSource dataSource() {
return new JndiDataSourceLookup().getDataSource("jdbc/myds_admin");
}
#Primary
#Bean(name = "entityManagerFactoryAdmin")
public LocalContainerEntityManagerFactoryBean
entityManagerFactory(
EntityManagerFactoryBuilder builder,
#Qualifier("dataSourceAdmin") DataSource dataSource
) {
return builder.dataSource(dataSource).
packages("com.demo.domain.model.entities").
persistenceUnit("read-write").
build();
}
#Primary
#Bean(name = "transactionManagerAdmin")
public PlatformTransactionManager transactionManager(
#Qualifier("entityManagerFactoryAdmin") EntityManagerFactory
entityManagerFactory
) {
return new JpaTransactionManager(entityManagerFactory);
}
}
I should have two classes like this with different package (Refer basePackages). But I dont want this solution instead want to use single repository package and the same repository class.
Solution that worked for me.
1) Created separate config classes one for admin user and app user each
2) Created seprate entity manager references one for admin user and app user each
3) Instantiated the same Repositoy class (without using #Repository annotation) through java code and using respective entity manager
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactoryAdmin"
)
public class AdminUserConfig {
#Primary
#Bean(name = "dataSourceAdmin")
public DataSource dataSourceAdmin(#Value("${spring.datasource.admin-user.jndi-name}") String key) {
return new JndiDataSourceLookup().getDataSource(key);
}
#Primary
#Bean(name = "entityManagerFactoryAdmin")
public LocalContainerEntityManagerFactoryBean entityManagerFactoryAdmin(
EntityManagerFactoryBuilder builder,
#Qualifier("dataSourceAdmin") DataSource dataSource
) {
return builder.dataSource(dataSource).
packages("com.demo.domain.model.entities").
persistenceUnit("read-write").
build();
}
#Bean(name = "entityManagerAdmin")
public EntityManager entityManagerAdmin(#Qualifier("entityManagerFactoryAdmin") EntityManagerFactory
entityManagerFactory) {
return SharedEntityManagerCreator.createSharedEntityManager(entityManagerFactory);
}
#Bean(name = "adminRepository")
public StoreRepo readWriteDimStoreRepository(#Qualifier("jpaRepositoryFactoryAdmin")
JpaRepositoryFactory repositoryFactory) {
return repositoryFactory.getRepository(StoreRepo.class);
}
}
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactoryApp"
)
public class AppUserConfig {
#Primary
#Bean(name = "dataSourceApp")
public DataSource dataSourceApp(#Value("${spring.datasource.App-user.jndi-name}") String key) {
return new JndiDataSourceLookup().getDataSource(key);
}
#Primary
#Bean(name = "entityManagerFactoryApp")
public LocalContainerEntityManagerFactoryBean entityManagerFactoryApp(
EntityManagerFactoryBuilder builder,
#Qualifier("dataSourceApp") DataSource dataSource
) {
return builder.dataSource(dataSource).
packages("com.demo.domain.model.entities").
persistenceUnit("read-only").
build();
}
#Bean(name = "entityManagerAdmin")
public EntityManager entityManagerApp(#Qualifier("entityManagerFactoryApp") EntityManagerFactory
entityManagerFactory) {
return SharedEntityManagerCreator.createSharedEntityManager(entityManagerFactory);
}
#Bean(name = "AppRepository")
public StoreRepo readOnlyStoreRepository(#Qualifier("jpaRepositoryFactoryApp")
JpaRepositoryFactory repositoryFactory) {
return repositoryFactory.getRepository(StoreRepo.class);
}
}
//#Repository
public interface StoreRepo extends JpaRepository<StoreAttribute, String> {
#Query("select storeAttributeName from StoreAttribute order by
storeAttributeName asc")
List<String> fetchAllStoreAttributeNames();
List<StoreAttribute> findAllByOrderByStoreAttributeNameAsc();
}
I have some trouble to configure my multimodule projet with multiple datasources. So, I need your help.
I have allready try :
Springboot multimodule project
SpringBoot ComponentScan issue with multi-module project
SpringBoot scanBasePackages not working in multi module project
And https://mhdevelopment.wordpress.com/2014/09/16/how-to-configure-spring-boot-with-jpa-and-multiple-projects/
But nothing work, i have the same issue.
So, that m'y multi-module classpath:
BusinessModule, that include repositories and Entities:
base package : com.mycompany.business.
In that module, i have an external dependency where we can found #Entity class ( package : com.mycompany.model)
RestModule, that are used to use BusinessModule.
base package : com.mycompany.rest
Business configuration
Configuration for datasources
First data source:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactory",
basePackages = {
"com.mycompany.business.repository", "com.mycompany.model" })
#PropertySource(value =

When i try to start test or app, i have this error:
java.lang.IllegalArgumentException: Not a managed type: class com.mycompany.model.CDocument
I don't know why... Any help ?
I am trying to test my repository layer using Spring Boot 2.0.1 but when I run my test class, Spring tries to instantiate a Config class not from the test package.
Here is the test code:
TestConfig.class
#Configuration
#Import(value = {TestDatabaseConfig.class})
#Profile("local")
public class TestConfig {
}
TestDatabaseConfig.class
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "logEntityManagerFactory",
transactionManagerRef = "logTransactionManager",
basePackages = { "it.xxx.yyy.repository.log" })
#EntityScan(basePackages = {"it.xxx.yyy.model.log", "it.xxx.yyy.common"})
#Profile("local")
public class TestDatabaseConfig {
#Bean("logDataSourceProperties")
public DataSourceProperties logDataSourceProperties() {
return new DataSourceProperties();
}
#Bean(name = "logDataSource")
public DataSource dataSource(#Qualifier("logDataSourceProperties") DataSourceProperties properties) {
return new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.H2)
.addScript("classpath:schema.sql")
.build();
}
#Bean(name = "logEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean logEntityManagerFactory(EntityManagerFactoryBuilder builder,
#Qualifier("logDataSource") DataSource logDataSource) {
return builder.dataSource(logDataSource)
.packages("it.xxx.model.log")
.persistenceUnit("log")
.build();
}
#Bean(name = "logTransactionManager")
public PlatformTransactionManager logTransactionManager(#Qualifier("logEntityManagerFactory")EntityManagerFactory logEntityManagerFactory) {
return new JpaTransactionManager(logEntityManagerFactory);
}
}
When I run this class
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles("local")
public class LogRepositoryTest {
#Autowired
private ResultLogRepository resultLogRepository;
#Test
public void init(){
}
}
it says :
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kafkaProducer': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'kafka.topic.operation' in value "${kafka.topic.operation}"
[...]
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'kafka.topic.operation' in value "${kafka.topic.operation}"
But I cannot understand why it brings up my KafkaProducer.class from my main package (that has #Configuration annotation on it).
In your LogRepositoryTest test class you should indicate the alternate test configuration class that should be taken into account, in your case I think should be the TestConfig.
From Spring Boot documentation:
If you are familiar with the Spring Test Framework, you may be used to using #ContextConfiguration(classes=…) in order to specify which Spring #Configuration to load. Alternatively, you might have often used nested #Configuration classes within your test.
So annotate LogRepositoryTest with #ContextConfiguration(classes = {TestConfig.class})
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles("local")
#ContextConfiguration(classes = {TestConfig.class})
public class LogRepositoryTest {
#Autowired
private ResultLogRepository resultLogRepository;
#Test
public void init(){
}
}
UPDATE
Also annotate your configuration class with:
#EnableAutoConfiguration
Something like:
#Configuration
#EnableAutoConfiguration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "logEntityManagerFactory",
transactionManagerRef = "logTransactionManager",
basePackages = { "it.xxx.yyy.repository.log" })
#EntityScan(basePackages = {"it.xxx.yyy.model.log", "it.xxx.yyy.common"})
#Profile("local")
public class TestDatabaseConfig {
//...
}
UPDATE 2
For error:
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.boot.autoconfigure.jdbc.DataSourceProperties' available: expected single matching bean but found 2: logDataSourceProperties,spring.datasource-org.springframework.boot.autoconfigure.jdbc.DataSourceProperties
Completely remove the method:
#Bean("logDataSourceProperties")
public DataSourceProperties logDataSourceProperties() {
return new DataSourceProperties();
}
and change your:
#Bean(name = "logDataSource")
public DataSource dataSource(#Qualifier("logDataSourceProperties") DataSourceProperties properties) {
// ...
}
to:
#Bean(name = "logDataSource")
public DataSource dataSource(DataSourceProperties properties) {
// ...
}
I need to use multiple databases.
I am using Spring Boot + Spring Data JPA,
so I have two configuration classes:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(basePackages="com.rest.dao.first",
entityManagerFactoryRef = "firstEntityManagerFactory", transactionManagerRef = "firstTransactionManager")
public static class DnbbJdbcConfig {
#Primary
#Bean
#ConfigurationProperties(prefix="datasource.first")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
#Primary
#Bean(name = "firstEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder) {
return builder
.dataSource(dataSource())
.packages("com.rest.dao.first")
.persistenceUnit("first")
.build();
}
#Primary
#Bean(name = "firstTransactionManager")
PlatformTransactionManager transactionManager(EntityManagerFactoryBuilder builder) {
return new JpaTransactionManager(entityManagerFactory(builder).getObject());
}
}
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(basePackages="com.rest.dao.second",
entityManagerFactoryRef = "secondEntityManagerFactory", transactionManagerRef = "secondTransactionManager")
public static class SmsJdbcConfig {
#Bean
#ConfigurationProperties(prefix="datasource.second")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
#Bean(name = "secondEntityManagerFactory")
#PersistenceContext(unitName = "second")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder) {
return builder
.dataSource(dataSource())
.packages("com.rest.dao.second")
.persistenceUnit("second")
.build();
}
#Bean(name = "secondTransactionManager")
PlatformTransactionManager transactionManager(EntityManagerFactoryBuilder builder) {
return new JpaTransactionManager(entityManagerFactory(builder).getObject());
}
}
I guess there is not error and correct.
So, when I use default repository then not error.
(e.g userRepository.findById() - not error in multi datasources)
But, When I use custom repository then error occur.
(https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.custom-implementations)
Custom Implements
public class FirstRepositoryImpl extends QueryDslRepositorySupport implements FirstCustomRepository {
public FirstRepositoryImpl() {
super(First.class);
}
#PersistenceContext(unitName = "first")
private EntityManager entityManager;
private QFirst first = QFirst.first;
#Override
public List<String> messages() {
JPAQuery query = new JPAQuery(entityManager);
return query.from(first).list(first.message);
}
}

Did I misconfigure something?
I wrote sample code in my github repository..
https://github.com/okihouse/spring-boot-multiple-datasource-with-querydsl
Solved myself:
I'm check QueryDslRepositorySupport.class and found out.
#PersistenceContext
public void setEntityManager(EntityManager entityManager) {
Assert.notNull(entityManager);
this.querydsl = new Querydsl(entityManager, builder);
this.entityManager = entityManager;
}
#PersistenceContext have not "unitName"
So, Spring can't inject EntityManager.
I create QueryDslRepositorySupportWrapper.java
and inject EntityManager manually.
And It works.
