Failed to bind properties under 'spring.datasource' to javax.sql.DataSource:

Springboot在更换数据源的为druid的时候，报错：

Description:

Failed to bind properties under 'spring.datasource' to javax.sql.DataSource:

Property: spring.datasource.filters
Value: stat,wall,log4j
Origin: class path resource [application.yml]:22:14
Reason: org.apache.log4j.Logger

Action:

Update your application's configuration

原因是没有引入log4j

<!-- https://mvnrepository.com/artifact/log4j/log4j -->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>

ok ,再次启动即可成功。
