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)2021-01-14 10:57:34.525 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] <--- HTTP/1.1 200 (98ms)2021-01-14 10:57:34.525 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] connection: keep-alive2021-01-14 10:57:34.525 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] content-type: application/json2021-01-14 10:57:34.525 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] date: Thu, 14 Jan 2021 02:57:34 GMT2021-01-14 10:57:34.525 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] server: nginx/1.19.02021-01-14 10:57:34.526 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - ServiceClient#getDealerItemListByParams] transfer-encoding: chunked2021-01-14 10:57:34.526 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] vary: Accept-Encoding2021-01-14 10:57:34.526 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] 2021-01-14 10:57:34.528 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] {"code":"000000","description":http://"SUCCESS","data":2021-01-14 10:57:34.528 [http-nio-8080-exec-1] DEBUG c.n.s.r.service.analysis.fegin.AdminServiceClient - TID: N/A - [ServiceClient#getDealerItemListByParams] <--- END HTTP (2692-byte body)
