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 (the profiles test are currently active).
解决办法：
在SprinBoot启动器上加入：(exclude = {DataSourceAutoConfiguration.class})
异常二： No active profile set, falling back to default profiles: default
解决办法：
spring.profiles.active=test
集成fegin

Description:
Field orderDao in com.hm.service.impl.OrderServiceImpl required a bean of type 'com.hm.dao.OrderDao' 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.hm.dao.OrderDao' in your configuration.
Process finished with exit code 0
解决点：在改服务项目内没有引入mybatis-spring-boot-starter导致@Mapper注解无效，使得@Autowired注入无效，无法引用
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.3.0
整合fegin出现同服务多此注册错误

Description:
The bean 'pay.FeignClientSpecification' could not be registered. A bean with that name has already been defined and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
Process finished with exit code 0
解决：第一种是整合到一个类中
第二种是通过配置允许这种方式存在
spring:
application:
name: pc-web
配置
spring:
main:
allow-bean-definition-overriding: true
