Feign超时 yml文件配置

ribbon:#  #指建立连接后从服务端读取到可用资源所用的时间  ReadTimeOut: 10000#建立连接所用的时间，适用于网络状况正常的情况下，两端连接所需要的时间  ConnectTimeout: 5000

Feign用法和基本配置

SpringBoot集成Feign在不使用注册中心实现模块之间的调用

今天就来说下怎么使用Fegin在不使用注册中心的情况下进行模块之间的调用。原因是：在项目小的情况下，而且还必须要调用其他模块的接口，那么这个时候就要用fegin了，当然还有其他的方法，但我在这里只说这一种简单的方法。

上代码:

首先说下我的模块结构

test1是根模块用于对子模块Maven坐标的版本控制管理其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">    <modelVersion>4.0.0</modelVersion>    <groupId>com.person</groupId>    <artifactId>test1</artifactId>    <packaging>pom</packaging>    <version>1.0-SNAPSHOT</version>    <modules>        <module>provider</module>        <module>consumer</module>        <module>pojo</module>    </modules>    <!--spring boot 环境 -->    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>2.1.0.RELEASE</version>        <relativePath/>    </parent>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>        <java.version>1.8</java.version>        <!--spring cloud 版本-->        <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>    </properties>    <!--引入Spring Cloud 依赖-->    <dependencyManagement>        <dependencies>            <dependency>                <groupId>com.person</groupId>                <artifactId>pojo</artifactId>                <version>1.0-SNAPSHOT</version>            </dependency>            <dependency>                <groupId>org.springframework.cloud</groupId>                <artifactId>spring-cloud-dependencies</artifactId>                <version>${spring-cloud.version}</version>                <type>pom</type>                <scope>import</scope>            </dependency>            <!--spring boot WEB-->            <dependency>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-starter-web</artifactId>                <version>2.1.1.RELEASE</version>            </dependency>            <!--feign-->            <dependency>                <groupId>org.springframework.cloud</groupId>                <artifactId>spring-cloud-starter-openfeign</artifactId>                <version>2.1.1.RELEASE</version>            </dependency>            <dependency>                <groupId>org.projectlombok</groupId>                <artifactId>lombok</artifactId>                <version>1.18.10</version>                <scope>provided</scope>            </dependency>        </dependencies>    </dependencyManagement></project>

紧接着在test1模块下新建两个模块分别为consumer，provider和pojo，其中consumer使用Feign调用provider模块的接口，pojo模块放实体类

首先在test1模块下新建pojo模块

pojo模块的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模块下新建Goods实体类供其他模块使用：

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不能为空")    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的模块下新建feign调用类

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);}

上面代码所示 url代表想要调用的模块的前缀因为我的provider模块的端口是8011因此http://localhost:8011就是我的provider前缀，下面的请求路径“/person/findone/{id}”指的是我的provider模块接口路径

下面在consumer模块下新建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);    }}

接下来新建provider模块

provider的yml文件：

server:  port: 8011

其pom.xml坐标：

<?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.*;@RestController@RequestMapping("/person")public class GoodsController {    @GetMapping("/findone/{id}")    public Goods findOne(@PathVariable("id") String id) {        return new Goods("1","红苹果","8888","红色");    }}

这个时候在浏览器里面输入http://localhost:8012/order/findone/12回车
