Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded datasource could

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).

首先我用的是SpringCloud调用远程仓库的配置文件获取数据连接的，

根据网上的一些信息就行修改

部分解决策略如下：

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

虽然可以，但是出现如下扫描不到dao的包的情况

Description:

Field codeDao in com.slin.stu.service.impl.CodeServiceImpl required a bean of type 'com.slin.stu.dao.CodeDao' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'com.slin.stu.dao.CodeDao' in your configuration.

 部分解决策略如下：

@ComponentScan("com.slin.stu.dao")// 扫描具体的包

然后可以启动，但是访问时候访问不了。都进不了Controller层。

=====>>最终解决方案：

1、将resource下面的application.yml改为bootstrap.yml

2、原来添加的那些注解也可以撤掉

然后启动就正常了，访问也OK
