Я переношу существующее приложение командной строки Spring-Batch в webapp, используя spring-boot-starter-web и spring-boot-starter-data-jpa вместе с функцией Spring- batch-admin (версия 1.3.0).Spring-Boot Webapp с несколькими базами данных JTA выбрасывает BeanCreationException
Я попытался настроить приложение так, чтобы он мог работать с несколькими базами данных. После многих попыток и ошибок я наконец последовал за этим примером JTA stackoverflow.com/questions/22779155/.
Но все же я сталкиваюсь с тем же BeanCreationException снова и снова (см. StackTrace в конце сообщения).
Возможно, возникла проблема из-за интеграции с пружинным пакетом-админ?
Вот как ServletInitializer выглядит следующим образом:
@Configuration
@EnableAutoConfiguration(exclude = { BatchAutoConfiguration.class,
DataSourceAutoConfiguration.class, WebMvcAutoConfiguration.class })
@Import(MainConfiguration.class)
public class BatchAdmin extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(BatchAdmin.class, args);
}
// ...
}
Здесь основным классам конфигурации, как это было предложено в afromentioned SO-статье:
@Configuration
@ComponentScan("com.company.*")
@Import({ ServletConfiguration.class, WebappConfiguration.class, Db1Configuration.class,
Db2Configuration.class })
@EnableTransactionManagement
public class MainConfiguration {
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
hibernateJpaVendorAdapter.setShowSql(true);
hibernateJpaVendorAdapter.setGenerateDdl(true);
hibernateJpaVendorAdapter.setDatabase(Database.POSTGRESQL);
hibernateJpaVendorAdapter.setDatabasePlatform(MyPGDialect.class.getName());
return hibernateJpaVendorAdapter;
}
@Bean(name = "userTransaction")
public UserTransaction userTransaction() throws Throwable {
UserTransactionImp userTransactionImp = new UserTransactionImp();
userTransactionImp.setTransactionTimeout(10000);
return userTransactionImp;
}
@Bean(name = "atomikosTransactionManager", initMethod = "init", destroyMethod = "close")
public TransactionManager atomikosTransactionManager() throws Throwable {
UserTransactionManager userTransactionManager = new UserTransactionManager();
userTransactionManager.setForceShutdown(false);
return userTransactionManager;
}
@Bean(name = "transactionManager")
@DependsOn({ "userTransaction", "atomikosTransactionManager" })
public PlatformTransactionManager transactionManager() throws Throwable {
UserTransaction userTransaction = userTransaction();
TransactionManager atomikosTransactionManager = atomikosTransactionManager();
return new JtaTransactionManager(userTransaction, atomikosTransactionManager);
}
}
И для каждой базы данных, это собственный класс конфигурации :
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactory1",
transactionManagerRef = "transactionManager",
basePackages = { "com.company.model.repository" })
@DependsOn("transactionManager")
public class Db1Configuration {
@Autowired
private JpaVendorAdapter jpaVendorAdapter;
@Bean(name = "dataSource1", initMethod = "init", destroyMethod = "close")
public DataSource osmDataSource() {
PGXADataSource pgDataSource = new PGXADataSource();
pgDataSource.setServerName("localhost");
pgDataSource.setDatabaseName("db1");
pgDataSource.setPortNumber(5432);
pgDataSource.setUser("postgres");
pgDataSource.setPassword("postgres");
AtomikosDataSourceBean xaDataSource = new AtomikosDataSourceBean();
xaDataSource.setXaDataSource(pgDataSource);
xaDataSource.setUniqueResourceName("datasource1");
return xaDataSource;
}
@Bean(name = "entityManagerFactory1")
public LocalContainerEntityManagerFactoryBean customerEntityManager() throws Throwable {
LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
entityManager.setDataSource(osmDataSource());
entityManager.setJpaVendorAdapter(jpaVendorAdapter);
entityManager.setPackagesToScan("com.company.model.domain");
entityManager.setPersistenceUnitName("persistenceUnit1");
HashMap<String, Object> properties = new HashMap<String, Object>();
properties.put("hibernate.transaction.jta.platform", AtomikosJtaPlatform.class.getName());
// properties.put("javax.persistence.transactionType", "JTA");
properties.put("hibernate.hbm2ddl.auto", "");
entityManager.setJpaPropertyMap(properties);
return entityManager;
}
}
Это то, что дает мне его доходит до:
