怎么使用?
注意:FeignClinet 是在消费段调用。Feign自带负载均衡配置项
1.导入pom
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>cloud2020</artifactId> <groupId>com.atguigu.springcloud</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>cloud-consumer-feign-order80</artifactId> <description>订单消费者之feign</description> <dependencies> <!--openfeign--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> <!--eureka client--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <dependency> <groupId>com.atguigu.springcloud</groupId> <artifactId>cloud-api-common</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--监控--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <!--热部署--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> </project>
2.修改yml
YML
3.主启动类
package com.atguigu.springcloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.cloud.openfeign.EnableFeignClients; @SpringBootApplication @EnableEurekaClient @EnableFeignClients public class OrderFeignMain80 { public static void main(String[] args) { SpringApplication.run(OrderFeignMain80.class, args); } }
4.总结
OpenFeign默认等待1秒钟,超过后报错,OpenFeign默认支持Ribbon,YML文件里需要开启OpenFeign客户端超时控制
server: port: 80 eureka: client: register-with-eureka: false fetch-registry: true service-url: defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka # 设置feign客户端超时时间(OpenFeign默认支持ribbon) ribbon: # 指的是建立连接所用的时间,适用于网络状态正常的情况下,两端连接所用的时间 ReadTimeout: 5000 # 指的是建立连接后从服务器读取到可用资源所用的时间 ConnectTimeout: 5000
OpenFeign日志打印功能
日志级别:
如果想在Openfeign里面使用日志服务的话,需要配置bean
package com.atguigu.springcloud.config; import feign.Logger; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /** * OpenFeignClient配置 * * @author zzyy * @create 2020/3/6 18:02 **/ @Configuration public class FeignConfig { /** * feignClient配置日志级别 * * @return */ @Bean public Logger.Level feignLoggerLevel() { // 请求和响应的头信息,请求和响应的正文及元数据 return Logger.Level.FULL; } }
yml文件里面也是需要配置的
server: port: 80 eureka: client: register-with-eureka: false fetch-registry: true service-url: defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka # 设置feign客户端超时时间(OpenFeign默认支持ribbon) ribbon: # 指的是建立连接所用的时间,适用于网络状态正常的情况下,两端连接所用的时间 ReadTimeout: 5000 # 指的是建立连接后从服务器读取到可用资源所用的时间 ConnectTimeout: 5000 logging: level: # feign日志以什么级别监控哪个接口 com.atguigu.springcloud.service.PaymentFeignService: debug
日志如下:
