Answer 1

1. springboot的事务也主要分为两大类，

   一是xml声明式事务，

   二是注解事务，注解事务也可以实现类似声明式事务的方法，

2. springboot 之 xml事务

7. springboot  注解事务

8. Transactional注解事务

   注：需要在进行事物管理的方法上添加注解@Transactional，或者偷懒的话直接在类上面添加该注解

9. 注解声明式事务

   @Configuration
   public class TxConfigBeanName {
   
   @Autowired
   private DataSourceTransactionManager transactionManager;
   
   // 创建事务通知
   
   @Bean(name = "txAdvice")
   public TransactionInterceptor getAdvisor() throws Exception {
   Properties properties = new Properties();
   properties.setProperty("get*", "PROPAGATION_REQUIRED,-Exception,readOnly");
   properties.setProperty("add*", "PROPAGATION_REQUIRED,-Exception,readOnly");
   properties.setProperty("save*", "PROPAGATION_REQUIRED,-Exception,readOnly");
   properties.setProperty("update*", "PROPAGATION_REQUIRED,-Exception,readOnly");
   properties.setProperty("delete*", "PROPAGATION_REQUIRED,-Exception,readOnly");
   TransactionInterceptor tsi = new TransactionInterceptor(transactionManager,properties);
   return tsi;
   }
   @Bean
   public BeanNameAutoProxyCreator txProxy() {
   BeanNameAutoProxyCreator creator = new BeanNameAutoProxyCreator();
   creator.setInterceptorNames("txAdvice");
   creator.setBeanNames("*Service", "*ServiceImpl");
   creator.setProxyTargetClass(true);
   return creator;
   }
   }
