在没加logback-spring.xml文件之前是可以正常启动。出现这种情况的原因是，spring把configuration 当做了一个bean来对待了，但是它并不是一个bean，所以我们要将logback-spring.xml剔除。剔除后logback也是生效的。

原代码：

//扫描了所有的xml
@ImportResource(locations = {"classpath:*.xml"})
@SpringBootApplication
public class AuthApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthApplication .class, args);
    }
}

修改后代码：

//指定需要扫描的xml
@ImportResource(locations = {"classpath:applicationContext.xml","classpath:auth-consumer.xml","classpath:auth-provider.xml"})
@SpringBootApplication
public class AuthApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthApplication .class, args);
    }
}
