Использование нескольких EntityManager с Spring Data REST

2 голосов
/ 08 июня 2019

Я использую Spring Boot 2, Spring Data REST, Spring HATEOAS, Spring JPA, Hibernate. Мой проект работал нормально до последнего изменения, когда я добавил новый EntityManager.

Это начальный класс: 

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class})
@EnableAsync
@ComponentScan(basePackages = {"cloud.myapp", "management"})
public class OptixServerApplication {

    public static void main(String[] args) {

        SpringApplication.run(ServerApplication.class, args);
    }
}

это первый EntityManager: 

@Configuration
@Profile("prod")
@EnableJpaRepositories(
        basePackages = "cloud.myapp.server.repositories",
        entityManagerFactoryRef = "entityManagerFactory",
        transactionManagerRef = "transactionManager"
)
public class HibernateConfig {

    @Autowired
    private Environment env;

    @Autowired
    private LocalValidatorFactoryBean validator;

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(MultiTenantConnectionProvider multiTenantConnectionProviderImpl,
                                                                       CurrentTenantIdentifierResolver currentTenantIdentifierResolverImpl) throws InstantiationException, IllegalAccessException,
            ClassNotFoundException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException, SecurityException {
        Map<String, Object> properties = new HashMap<>();
        properties.put(org.hibernate.cfg.Environment.MULTI_TENANT, MultiTenancyStrategy.DATABASE);
        properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_CONNECTION_PROVIDER, multiTenantConnectionProviderImpl);
        properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, currentTenantIdentifierResolverImpl);
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setPersistenceUnitName("myapp.U");
        em.setDataSource(dataSource());
        em.setPackagesToScan("cloud.myapp.server");
        em.setJpaPropertyMap(properties);

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);

        // Interceptor for Agents
        // properties.put("hibernate.session_factory.interceptor", agentInterceptor());
//        properties.put("hibernate.session_factory.interceptor", hibernateInterceptor());
        em.setJpaPropertyMap(properties);
        em.afterPropertiesSet();

        return em;
    }

    @Primary
    @Bean
    public DataSource dataSource() throws InstantiationException, IllegalAccessException, ClassNotFoundException, IllegalArgumentException,
            InvocationTargetException, NoSuchMethodException, SecurityException {
        final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
        dataSource.setDriver(((Driver) Class.forName(env.getProperty("primary.datasource.driver-class-name")).getDeclaredConstructor()
                .newInstance(null)));
        dataSource.setUrl(env.getProperty("primary.datasource.url"));
        dataSource.setUsername(env.getProperty("primary.datasource.username"));
        dataSource.setPassword(env.getProperty("primary.datasource.password"));
        return dataSource;
    }

    @Primary
    @Bean
    public PlatformTransactionManager transactionManager(MultiTenantConnectionProvider multiTenantConnectionProviderImpl,
                                                         CurrentTenantIdentifierResolver currentTenantIdentifierResolverImpl) throws InstantiationException, IllegalAccessException,
            ClassNotFoundException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException, SecurityException {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(
                entityManagerFactory(multiTenantConnectionProviderImpl, currentTenantIdentifierResolverImpl).getObject());
        return transactionManager;
    }
}

и это дополнительный: 

@Configuration
@PropertySource({"classpath:management.properties"})
@EnableJpaRepositories(
        basePackages = "cloud.management.server.repositories",
        entityManagerFactoryRef = "managementEntityManager",
        transactionManagerRef = "managementTransactionManager"
)
@Log4j2
public class ManagementDBConfig {
    @Autowired
    private Environment env;

    @Bean(name = "managementEntityManager")
    public LocalContainerEntityManagerFactoryBean managementEntityManager() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(managementDataSource());
        em.setPackagesToScan("cloud.management.server.model");

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<>();
        properties.put("hibernate.hbm2ddl.auto", env.getProperty("management.jpa.hibernate.ddl-auto"));
        properties.put("hibernate.dialect", env.getProperty("management.jpa.properties.hibernate.dialect"));
        properties.put("hibernate.show_sql", env.getProperty("management.jpa.hibernate.show_sql"));

        properties.put("hibernate.globally_quoted_identifiers_skip_column_definitions", env.getProperty("management.jpa.hibernate.globally_quoted_identifiers_skip_column_definitions"));


        em.setJpaPropertyMap(properties);

        return em;
    }

    @Bean
    public DataSource managementDataSource() {
        return createDataSource();
    }

    @Bean
    public PlatformTransactionManager managementTransactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(managementEntityManager().getObject());
        return transactionManager;
    }

    private DataSource createDataSource() {
        HikariConfig hikari = new HikariConfig();

        hikari.setJdbcUrl(env.getProperty("management.datasource.url"));
        hikari.setUsername(env.getProperty("management.datasource.username"));
        hikari.setPassword(env.getProperty("management.datasource.password"));

        // MySQL optimizations, see
        // https://github.com/brettwooldridge/HikariCP/wiki/MySQL-Configuration
        String keyPrefix = "management.hikari.";
        hikari.addDataSourceProperty("cachePrepStmts", env.getProperty(keyPrefix + "cachePrepStmts"));
        hikari.addDataSourceProperty("prepStmtCacheSize", env.getProperty(keyPrefix + "prepStmtCacheSize"));
        hikari.addDataSourceProperty("prepStmtCacheSqlLimit", env.getProperty(keyPrefix + "prepStmtCacheSqlLimit"));
        hikari.addDataSourceProperty("useServerPrepStmts", env.getProperty(keyPrefix + "useServerPrepStmts"));

        hikari.setMinimumIdle(Integer.valueOf(env.getProperty(keyPrefix + "minimumIdle")));
        hikari.setMaximumPoolSize(Integer.valueOf(env.getProperty(keyPrefix + "maximumPoolSize")));
        hikari.setIdleTimeout(Long.valueOf(env.getProperty(keyPrefix + "idleTimeout")));
        String connectionPoolName = "JPAHikari_management";

        hikari.setPoolName(connectionPoolName);
        // mysql wait_timeout 600seconds
        hikari.setMaxLifetime(Long.valueOf(env.getProperty(keyPrefix + "maxLifetime")));
        hikari.setLeakDetectionThreshold(Long.valueOf(env.getProperty(keyPrefix + "leakDetectionThreshold")));

        DataSource dataSource = new HikariDataSource(hikari);

        return dataSource;
    }
}

Первый entityManager имеет дело с несколькими арендаторами, поэтому я реализовал MultiTenantConnectionProvider: 

@Component
@Log4j2
public class MultiTenantConnectionProviderImpl implements MultiTenantConnectionProvider {
    private static final long serialVersionUID = 3193007611085791247L;

    @Autowired
    private ConnectionPoolManager connectionPoolManager;

    @Override
    public void releaseAnyConnection(Connection connection) throws SQLException {
        connection.close();
    }

    @Override
    public Connection getAnyConnection() throws SQLException {
        return connectionPoolManager.getConnection(TenantContext.TENANT_DEFAULT);
    }

    @Override
    public Connection getConnection(String tenantId) throws SQLException {
        // log.info("getConnection " + tenantId);
        Connection connection = connectionPoolManager.getConnection(tenantId);

        return connection;
    }

    @Override
    public void releaseConnection(String tenantId, Connection connection) throws SQLException {
        log.info("releaseConnection " + tenantId);
        connection.close();
    }

    @Override
    public boolean supportsAggressiveRelease() {
        return false;
    }

    @Override
    public boolean isUnwrappableAs(Class unwrapType) {
        return false;
    }

    @Override
    public <T> T unwrap(Class<T> unwrapType) {
        return null;
    }

}

и это мой ConnectionPoolManager: 

@Component
@Profile({"prod"})
@Log4j2
public class ConnectionPoolManagerImpl implements ConnectionPoolManager {

    @Autowired
    private DataSourceCache dataSourceCache;

    @Autowired
    private TenantDbCache tenantDbCache;

    @Autowired
    private DatabaseInstanceRepository databaseInstanceRepository;

    @Autowired
    private PasswordEncrypt passwordEncrypt;

    @Autowired
    private Environment env;

    @Autowired
    private DataSource primaryDataSource;



    @Override
    public Connection getConnection(@NotNull String tenantId) {
        //use second DB repository, create(or reuse) a datasource and from that get the connection
    }


}

Когда я запускаю проект, я получаю следующее исключение:
