Spring Cloud Alibaba OpenFeign 日志配置

OpenFeign提供了日志打印功能,我们可以通过配置来调整日恙级别,从而了解Feign 中 Http请求的细节。

说白了就是对Feign接口的调用情况进行监控和输出

日志级别

  • NONE:默认的,不显示任何日志;
  • BASIC:仅记录请求方法、URL、响应状态码及执行时间;
  • HEADERS:除了BASIC中定义的信息之外,还有请求和响应的头信息;
  • FULL:除了HEADERS中定义的信息之外,还有请求和响应的正文及元数据。
package com.wsm.product.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController
@RequestMapping("/product")
public class ProductController {

    @Value("${server.port}")
    String port;

    @RequestMapping("/{id}")
    public String get(@PathVariable("id") Integer id){
        System.out.println("查询商品");
        return "查询商品"+id+":"+port;
    }
}

局部配置有两种方式,一是上面的配置类,二是通过配置文件

server:
  port: 8040
  #应用名称  (nacos 会将该名称当作服务名称)
spring:
  application:
    name: order-openfeign-service
  cloud:
    nacos:
#      server-addr: 127.0.0.1:8848
      server-addr: 192.168.133.128:8847  #集群 nginx 负载均衡访问 nacos
      discovery:
        username: nacos
        password: nacos
        namespace: public
#springboot 默认的日志级别是info,feign的debug日志级别就不会输出
logging:
  level:
#    com.wsm.order.feign: debug
    com.wsm.order.feign.StockFeignService: debug
# Feign 日志局部配置
feign:
  client:
    config:
      product-service:
        loggerLevel: BASIC
