SpringBoot之解决整合多数据源多事物注解问题

概念:

　　因为整合了多数据源,就代表我的项目中存在多个事物管理器,这样就不能直接使用@Transactional

修改代码:

修改user2接口模拟异常,查看事物是否回滚,添加@Transactional

启动测试:

访问user2接口报错

2021-01-28 12:36:39,975 [http-nio-8082-exec-3] ERROR (DirectJDKLog.java:175)- Servlet.service() for servlet [dispatcherServlet]
 in context with path [] threw exception [Request processing failed; nested exception is 
org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 
'org.springframework.transaction.TransactionManager' available: expected single matching bean but found 2: 
springbootTransactionManager,springbootdtsTransactionManager] with root cause
org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.transaction.TransactionManager'
 available: expected single matching bean but found 2: springbootTransactionManager,springbootdtsTransactionManager

因为我们直接使用的@Transactional但是在Spring的事物管理器中却有两个事物管理器,这时他就不知道使用哪个了

这里说一下,在Springboot2之后默认就是开始事物的不用单独写@EnableTransactionManager了
