Spring 数据 JPA 多个数据源 - CockroachDb 空间

Question

My application has two data sources. First datasource access Postgre using JdbcTemplate. Second datasource access CockroachDb using Spring Data JPA.

So i created two configurations for this datasources.

Persisting to both datasources works fine, except objects with spatial data. When i trying to save spatial data to CockroachDb, i get an error:

Hibernate: select geoobject0_.id as id1_2_0_, geoobject0_.address as address2_2_0_, geoobject0_.address_id as address_3_2_0_, geoobject0_.created as created4_2_0_, geoobject0_.flat_count as flat_cou5_2_0_, geoobject0_.geo_provider_id as geo_prov6_2_0_, geoobject0_.geometry as geometry7_2_0_, geoobject0_.hq_id as hq_id8_2_0_, geoobject0_.is_generated as is_gener9_2_0_, geoobject0_.is_living as is_livi10_2_0_, geoobject0_.payload as payload11_2_0_, geoobject0_.source_id as source_12_2_0_, geoobject0_.type as type13_2_0_, geoobject0_.uic_id as uic_id14_2_0_, geoobject0_.version_id as version15_2_0_, geoobject0_.voter_count as voter_c16_2_0_ from geo_service.geo_object geoobject0_ where geoobject0_.id=?

Java configuration:

For Postgre:

@Configuration
public class UicDbConfig {

    @Bean(name = "uicDataSource")
    @Qualifier("uicDataSource")
    @Primary
    @ConfigurationProperties(prefix="spring.uic.datasource")
    public DataSource secondaryDataSource() {
        return DataSourceBuilder.create().build();
    }
}

For CockroachDb:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "ru.stimul.geoservice.repo",
        entityManagerFactoryRef = "primaryEntityManagerFactory",
        transactionManagerRef = "primaryTransactionManager")
public class CockroachDbConfig {

    @Autowired
    private Environment env;

    @Bean("primaryDataSource")
    @ConfigurationProperties(prefix="spring.primary.datasource")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "primaryEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory(EntityManagerFactoryBuilder builder
            ,@Qualifier("primaryDataSource") DataSource primaryDataSource){

        LocalContainerEntityManagerFactoryBean em = builder
                .dataSource(primaryDataSource)
                .packages("ru.stimul.geoservice.domain.primary")
                .persistenceUnit("domains")
                .build();

        final HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        em.setJpaProperties(additionalProperties());

        return em;

    }

    @Bean(name = "primaryTransactionManager")
    public JpaTransactionManager transactionManager(@Qualifier("primaryEntityManagerFactory") EntityManagerFactory primaryEntityManagerFactory){
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(primaryEntityManagerFactory);

        return transactionManager;
    }


    private Properties additionalProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.dialect", env.getProperty("spring.primary.jpa.properties.hibernate.dialect"));
        properties.setProperty("hibernate.show_sql", env.getProperty("spring.primary.jpa.show-sql"));
        return properties;
    }
}

I recommend to you use Hikari to handle multiple datasources.

    @Configuration
    @ConfigurationProperties(prefix = "first.datasource")
    @EnableTransactionManagement
    public class FirstDBConfig extends HikariConfig {
    
        @Bean
        public DataSource firstDataSource() {
            return new HikariDataSource(this);
        }
    ...........................................
    
    @Configuration
    @ConfigurationProperties(prefix = "second.datasource")
    @EnableTransactionManagement
    @EnableJpaRepositories( basePackages = {
                "com.myproyect.repos"
        },
        entityManagerFactoryRef = "myEntityManager",
        transactionManagerRef = "myTransactionManager")
    public class SecondDBConfig extends HikariConfig {
    
        @Bean
        public DataSource secondDataSource() {
            return new HikariDataSource(this);
        }
