循环依赖于"liquibase"和"entityManagerFactory"之间的关系

Question

我用依赖的spring initializer创建了一个空的新spring启动项目

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>

当我运行项目时，我得到了这个错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [org/springframework/boot/autoconfigure/liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]: Circular depends-on relationship between 'liquibase' and 'entityManagerFactory'

任何人都知道这个

Answer 1

我在Spring 2.6.6中遇到了同样的问题，我用下面相同的解决方案修复了它。带有弹簧靴的Flyway Core会出现错误Circular取决于'；delayedFlywayInitializer'；和'；entityManagerFactory'；

最有可能通过以下方式解决：

spring.jpa.defer-datasource-initialization=false (iso true)

Answer 2

我在spring主应用程序类中使用此注释

@SpringBootApplication(exclude = LiquibaseAutoConfiguration.class)
public class MainSpringApplication {
public static void main(String[] args) {
SpringApplication.run(MainSpringApplication.class, args);
}
}
