使用druid服务启动不了，添加log4j的maven依赖

---

APPLICATION FAILED TO START

---

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]:24:14
Reason: org.apache.log4j.Logger

报错中指出了原因，因为log4j的问题，所以重写添加了一个jar

	<dependency>
	    <groupId>log4j</groupId>
	    <artifactId>log4j</artifactId>
	    <version>1.2.17</version>
	</dependency>
