consul做配置中心遇见的BUG

今天开发一个微服务的oauth服务,我们用的是consul做配置中心,今天报了一个错误是:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

2018-09-26 14:55:42.577 ERROR 8888 --- [          main] o.s.b.d.LoggingFailureAnalysisReporter  :

***************************

APPLICATION FAILED TO START

***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following:

If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.

If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Disconnected from the target VM, address: '127.0.0.1:53565', transport: 'socket'

Process finished with exit code 1

由于这个错误网上很常见,以前也遇见过,我一看知道是什么问题,这个异常大概的意思是我的pom文件中引入的mybatis的左边没有用到,才会报这样的错,同时只要是在启动类上加上如下注解就可以解决:@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})但是尝试了很久还是没能狗解决,因为以前遇见过,也是同样的方法解决的很奇怪。经过出去抽了只眼,我就一直想不明白为什么,但是我突然想到,昨天调整过pom文件,突然我发现少了一个坐标。

解决方法:加上了如下的坐标

<dependency>

     <groupId>org.springframework.cloud</groupId>

     <artifactId>spring-cloud-starter-consul-config</artifactId>

</dependency>

用consul做配置中心少了这个坐标当然不行了,找了一上午bug,一根烟解决了。
