SpringCloud整合OpenFeign时@FeginClient注入错误

No bean found of type interface org.springframework.cloud.openfeign.Targeter for 服务名.

1. openfeign的版本要跟着SpringCloud走

1.  
   <!-- 父pom springcloud 依赖-->
2.  
   <dependency>
3.  
       <groupId>org.springframework.cloud</groupId>
4.  
       <artifactId>spring-cloud-dependencies</artifactId>
5.  
       <version>${springcloud.version}</version>
6.  
       <type>pom</type>
7.  
       <scope>import</scope>
8.  
   </dependency>
9.  
   引入时不用加版本号
10.  
    <dependency>
11.  
    <groupId>org.springframework.cloud</groupId>
12.  
    <artifactId>spring-cloud-starter-openfeign</artifactId>
13.  
    </dependency>

2. 注意包扫描路径的问题,如果写的包路径不能被Springboot默认路径扫描,则@EnableFeignClient(basePackages=手动加FeignClient的包路径)

3. feign配置如果引入了断路器要加入相关的依赖

1.  
   feign:
2.  
   #开启feign断路器 依赖hystrix包
3.  
   circuitbreaker:
4.  
   enabled: true
5.  
   client:
6.  
   config:
7.  
   default:
8.  
   connect-timeout: 60000
9.  
   read-timeout: 60000
10.  
    <dependency>
11.  
    <groupId>org.springframework.cloud</groupId>
12.  
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
13.  
    </dependency>

我就是加断路器的时候,忘记引入hystrix包,导致@FeignClient注入不了Targeter
