feign如何打印出http请求
作者：追梦的搬运工
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：
ms] ---> END HTTP (0-byte body)
