我正在使用Spring Data JPA我正在从一个方法保存多个对象，当保存第一个对象后发生了某些事情，那么第一个保存的对象应该是回滚但是当我看到日志我发现获取新事务时，这不会发生每个方法调用并在下面提交它是我的服务层方法，在第一个对象持久化之后我创建了“nullPointerException”
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public void testTransaction(HashMap<String, Object> hashMap) throws Exception {
try {
VendorType vendorType = (VendorType) hashMap.get("vendorType");
RenewalType renewalType = (RenewalType) hashMap.get("renewalType");
vendorTypeService.registerNewVendorType(vendorType);
Vehicle vehicle = null;
vehicle.getCompany_Id();
renewalTypeService.registerNewRenewalType(renewalType);
} catch (Exception e) {
System.err.println("inside method exception "+e);
}
}
下面是registerVendor方法，它在不同的服务方法中定义
@org.springframework.transaction.annotation.Transactional
public VendorType registerNewVendorType(final VendorType accountDto) throws Exception {
return VendorTyperepository.save(accountDto);
}
这是我的配置文件PersistenceJPAConfig.java
@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:persistence.properties" })
@ComponentScan({ "org.fleetopgroup.persistence" })
@EnableJpaRepositories(basePackages = "org.fleetopgroup.persistence.dao")
public class PersistenceJPAConfig {
@Autowired
private Environment env;
public PersistenceJPAConfig() {
super();
}
//
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(new String[] { "org.fleetopgroup.persistence.model" });
final HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaProperties(additionalProperties());
return em;
}
@Bean
public DataSource dataSource() {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
dataSource.setUrl(env.getProperty("jdbc.url"));
dataSource.setUsername(env.getProperty("jdbc.user"));
dataSource.setPassword(env.getProperty("jdbc.pass"));
return dataSource;
}
@Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
final Properties additionalProperties() {
final Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
hibernateProperties.setProperty("hibernate.dialect", env.getProperty("hibernate.dialect"));
hibernateProperties.setProperty("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
return hibernateProperties;
}

答案 0 :(得分：0)
问题是MySql数据库存储引擎在hibernate配置方言属性是MySQLDialect后更改为MySQLInnoDBDialect并将表引擎改为InnoDB现在它正常工作
hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
