feign打印出http请求

用openfign依赖需要将请求的方法中的http请求打印出来

需要做如下两步：

1.记录请求和响应的头文件

正文和元数据的日志，需要在配置文件指出需要打印日志的类

 @Bean
    Logger.Level feignLoggerLevel() {
        return Logger.Level.FULL;
    }

2.在配置文件中配置对应的包

logging:
  level:
    com.report.service.analysis.fegin.AdminServiceClient: debug

这样就会生效了，如下：
