Spring Data JPA map the stored procedure result to Non-Entity POJO from multiple data source

Question

I have tried to research on a better way of calling two stored procedures on two different data sources with no luck. Here is my scenario, I have connection to two data sources, each data source with a stored procedure. whenever I annotate one configuration as primary I get the results, the other configuration which is not mapped as primary throws an error

The given SqlResultSetMapping name [Unknown SqlResultSetMapping [Testing]] is unknown

When I set the other configuration for the class calling the stored procedure as primary, It shows results, but when both of them are not set as primary they throw an error

The given SqlResultSetMapping name [Unknown SqlResultSetMapping [Testing]] is unknown

Been stuck for several days. I will appreciate any help.Thank you in advance

my first config for calling the first data source

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "guru.springframework.multipledatasources.model.Card",
        entityManagerFactoryRef = "cardEntityManagerFactory",
        transactionManagerRef= "cardTransactionManager")
public class Cardonfiguration {

        @Bean
        @Primary
        @ConfigurationProperties("datasource.card")
        public DataSourceProperties cardDataSourceProperties() {
            return new DataSourceProperties();
        }

        @Bean
        @Primary
        @ConfigurationProperties("datasource.card.configuration")
        public DataSource cardDataSource() {
            return cardDataSourceProperties().initializeDataSourceBuilder()
                    .type(BasicDataSource.class).build();
        }

        @Primary
        @Bean(name = "cardEntityManagerFactory")
        public LocalContainerEntityManagerFactoryBean cardEntityManagerFactory(
                EntityManagerFactoryBuilder builder) {
            return builder
                    .dataSource(cardDataSource())
                    .packages(Card.class)
                    .build();
        }

        @Primary
        @Bean
        public PlatformTransactionManager cardTransactionManager(
                final @Qualifier("cardEntityManagerFactory") LocalContainerEntityManagerFactoryBean cardEntityManagerFactory) {
            return new JpaTransactionManager(Objects.requireNonNull(cardEntityManagerFactory.getObject()));
    }
}

my second config for the second data source

@Configuration
@EnableJpaRepositories(basePackages = "guru.springframework.multipledatasources.model.member",
        entityManagerFactoryRef = "memberEntityManagerFactory",
        transactionManagerRef= "memberTransactionManager")
public class MemberConfiguration {
    @Bean
    @ConfigurationProperties("datasource.member")
    public DataSourceProperties zamphiaDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @ConfigurationProperties("datasource.member.configuration")
    public DataSource memberDataSource() {
        return memberDataSourceProperties().initializeDataSourceBuilder()
                .type(BasicDataSource.class).build();
    }

    @Bean(name = "memberEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean memberEntityManagerFactory(
            EntityManagerFactoryBuilder builder) {
        return builder
                .dataSource(memberDataSource())
                .packages(member.class)
                .build();
    }

    @Bean
    public PlatformTransactionManager memberTransactionManager(
            final @Qualifier("memberEntityManagerFactory") LocalContainerEntityManagerFactoryBean memberEntityManagerFactory) {
        return new JpaTransactionManager(memberEntityManagerFactory.getObject());
    }

}

my controller for the first data source

@RequestMapping("/api/v1")
@RestController
public class CardReports {

    @PersistenceContext
    private EntityManager entityManager;

    @SuppressWarnings("unchecked")
    @RequestMapping("/reports/CARD/dailyreport")
    public List<Testing> getDailyAchievements(){
        List<Testing> list;
        StoredProcedureQuery query = entityManager.createStoredProcedureQuery("dailyreports", "Testing");
        try {
            // Execute query
            query.execute();
            list = query.getResultList();
        } finally {
            try {
                query.unwrap(ProcedureOutputs.class).release();
            } catch (Exception e) {
            }
        }
        return list;
    }
}

my non entity for the first data source

my second data source controller

            List list;
            StoredProcedureQuery query = entityManager.createStoredProcedureQuery("dailyreports", "Testing");
            try {
                // Execute query
                query.execute();
                list = query.getResultList();
            } finally {
                try {
                    query.unwrap(ProcedureOutputs.class).release();
                } catch (Exception e) {
                }
            }
            return list;
        }
    }

Answer 1

Your cardEntityManagerFactory will scan the package of Card.class for classes annotated with @ManagedSuperClass and memberEntityManagerFactory will scan the package of member.class

It looks like you are using the same POJO with SQLResultSetMapping "Testing" in both the controllers. But it is not clear in which package this POJO is. So make sure the package of your POJO is scanned by both the entity managers.

Also, You are simply auto wiring the entity manager without specifying name in both the controllers. As per my understanding, only the Primary entity manager will be autowired in both the controllers if you don't specify a Qualifier .

I think, you can try with @PersistenceContext(name = "cardEntityManagerFactory") and @PersistenceContext(name = "memberEntityManagerFactory") in the CardReports and MemberDaily controllers respectively.

Update

I had a look at your GitHub code and found that your BAISVReports controller was getting the primary entity manager only. So just autowired the entitymanager using @Qualifier as shown below and now the secondary entity manager is getting autowired. Now both controllers are able to find the SQLResultSetMapping

@RequestMapping("/api/v1")
@RestController
public class BAISVReports {

@Autowired
@Qualifier("baisvEntityManagerFactory")
private EntityManager entityManager;

I don't think SqlResultSetMapping works on @MappedSuperclass . Try to put it on an entity instead.
