在Spring Boot应用程序中禁用事务管理器

Question

How to disable transaction manager in Spring Boot application?

I have this exception :

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.transaction.PlatformTransactionManager] is defined

Because of @Transactional annotations (I use these annotations in an other app, so I can't remove, but there is a way to ignore it? By disable transaction manager?).

Answer 1

I guess you have three choices:

1. remove the annotation

2. supply a transaction manager

3. exclude the configuration class that adds @EnableTransactionManagement

In a Spring Boot app you only get @EnableTransactionManagement if you are using JDBC or JPA, so really there should be a transaction manager already. The only reason I can see for one not being there is you have spring-jdbc on the classpath but no database. If you have spring-tx and spring-jdbc on your classpath already (which seems to be the case) you can just add an in-memory database (eg h2) to get a transaction manager. That seems like the best solution to me. But you could also exclude DataSourceTransactionManagerAutoConfiguration in your @EnableAutoConfiguration .
