Swagger提示Unable to infer base url

错误信息为：
Unable to infer base url.
This is common when using dynamic servlet registration or when the API is behind an API Gateway.
The base url is the root of where all the swagger resources are served. For e.g. if the api is available at http://example.org/api/v2/api-docs then the base url is http://example.org/api/.
Please enter the location manually:

刚开始还可以正常工作，结果修改了一下resources中mybatis的xml文件路径，出现这个问题。仔细对比代码历史，发现原来是：

@SpringBootApplication(scanBasePackages = {"org..xxx.yyy.mapper..rule",
        "org..xxx.yyy.mapper..rule.dao"})
@EnableDiscoveryClient
@EnableCircuitBreaker
@EnableFeignClients(basePackages = {"org.xxx.yyy.mapper.rule.client"})
@EnableHystrix
@EnableHystrixDashboard
@EntityScan({"org.xxx.yyy.mapper.rule"})

原来是EntityScan、scanBasePackages和basePackages这些类包写错了。比如这个org.xxx.yyy.mapper.rule， 应该是org.xxx.yyy.rule
