這篇文章主要介紹了Feign超時在yml文件里的配置方式，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

Feign超時 yml文件配置

ribbon:
#  #指建立連接后從服務(wù)端讀取到可用資源所用的時間
  ReadTimeOut: 10000
#建立連接所用的時間，適用于網(wǎng)絡(luò)狀況正常的情況下，兩端連接所需要的時間
  ConnectTimeout: 5000

Feign用法和基本配置

SpringBoot集成Feign在不使用注冊中心實現(xiàn)模塊之間的調(diào)用

? 今天就來說下怎么使用Fegin在不使用注冊中心的情況下進行模塊之間的調(diào)用。原因是：在項目小的情況下，而且還必須要調(diào)用其他模塊的接口，那么這個時候就要用fegin了，當(dāng)然還有其他的方法，但我在這里只說這一種簡單的方法。

上代碼:

首先說下我的模塊結(jié)構(gòu)

test1是根模塊用于對子模塊maven坐標的版本控制管理其pom.xml如下：

                <version>${spring-cloud.version}</version>

            </dependency>
            <!--spring boot web-->

            </dependency>
        </dependencies>
    </dependencyManagement>
</project>

緊接著在test1模塊下新建兩個模塊分別為consumer，provider和pojo，其中consumer使用Feign調(diào)用provider模塊的接口，pojo模塊放實體類

首先在test1模塊下新建pojo模塊

pojo模塊的pom.xml:

<?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>test1</artifactId>
        <groupId>com.person</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>pojo</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>
</project>

在pojo模塊下新建Goods實體類供其他模塊使用：

package com.person.pojo.consumer;
import lombok.*;
import javax.validation.constraints.NotNull;
import java.io.Serializable;
@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
@Builder(toBuilder = true)
public class Goods implements Serializable {
    private static final long serialVersionUID = 1L;
    @NotNull(message = "id不能為空")
    private String id;
    private String name;
    private String price;
    private String colour;
}

consumer的yml文件：

server:
  port: 8012

consumer的pom.xml如下：

<?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>test1</artifactId>
        <groupId>com.person</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>consumer</artifactId>
    <dependencies>
        <dependency>
            <groupId>com.person</groupId>
            <artifactId>pojo</artifactId>
        </dependency>
        <!--feign-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
        <!--spring boot web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
</project>

首先在consumer的模塊下新建feign調(diào)用類

package com.person.feign;
import com.person.pojo.consumer.Goods;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
@FeignClient(name = "provider",url = "http://localhost:8011")
@RequestMapping("/person")
public interface GoodsFeignClient {
    @GetMapping("/findone/{id}")
    public Goods findOnebyId(@PathVariable("id") String id);
}

上面代碼所示 url代表想要調(diào)用的模塊的前綴因為我的provider模塊的端口是8011因此http://localhost:8011就是我的provider前綴，下面的請求路徑“/person/findone/{id}”指的是我的provider模塊接口路徑

下面在consumer模塊下新建controller方法：

package com.person.controller;
import com.person.feign.GoodsFeignClient;
import com.person.pojo.consumer.Goods;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/order")
public class OrderController {
  
    @Autowired
    private GoodsFeignClient goodsFeignClient;
    @GetMapping("/findone/{id}")
    public Goods findOnebyId(@PathVariable("id") String id) {
        return goodsFeignClient.findOnebyId(id);
    }
}

接下來新建provider模塊

provider的yml文件：

server:
  port: 8011

其pom.xml坐標：

<?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>test1</artifactId>
        <groupId>com.person</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>provider</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
        <dependency>
            <groupId>com.person</groupId>
            <artifactId>pojo</artifactId>
        </dependency>
        <!--spring boot web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
</project>

然后在provider 中新建controller：

package com.person.controller;
import com.person.pojo.consumer.Goods;
import com.person.service.GoodsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
/**
 * 服務(wù)提供方
 */
@RestController
@RequestMapping("/person")
public class GoodsController {
    @GetMapping("/findone/{id}")
    public Goods findOne(@PathVariable("id") String id) {
        return new Goods("1","紅蘋果","8888","紅色");
    }
}

這個時候在瀏覽器里面輸入http://localhost:8012/order/findone/12回車
