SpringBoot2 初始数据库循环依赖 The dependencies of some of the beans in the application context form a cycle

今天做初始化数据库，报一下异常

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

   userServiceImpl (field com.rude.springboot2.demo.dao.UserDao com.rude.springboot2.demo.service.impl.UserServiceImpl.userDao)
      ↓
   userDao defined in file [D:JavaideaIUworkspacestudyspringboot2demotargetclassescomrudespringboot2demodaoUserDao.class]
┌─────┐
|  sqlManagerFactoryBean defined in class path resource [com/ibeetl/starter/BeetlSqlSingleConfig.class]
↑     ↓
|  beetlSqlDataSource defined in class path resource [com/ibeetl/starter/BeetlSqlSingleConfig.class]
↑     ↓
|  dataSource defined in class path resource [com/rude/springboot2/demo/config/BeetlSqlConfiguration.class]
↑     ↓
|  org.springframework.boot.autoconfigure.jdbc.DataSourceInitializerInvoker
└─────┘
 

这就尴尬了，查了一天，还看了源代码，一天没吃饭了，中午查出来了。

解决方法，将代码下列代码添加    exclude = DataSourceAutoConfiguration.class

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

为：

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

问题解决，好了，不说了，简单的记录下，吃饭去了，都是泪啊！！！
