Today, the editor will share with you the relevant knowledge points about how to solve the failure of @ FeignClient injection service. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

@ FeignClient failed to inject service

Add comments above the entry class

@ EnableFeignClients (basePackages = {"com.ritoinfo.framework.evo.sp.sys.api", "com.yqjr.sp.eco.member"})

Due to the introduction of service jar packages using pom, if you do not add basePackage, you will not find the path where the package is located

Pit of Feign injection failure

Today I encountered a very bad problem: feign injection failed.

Error message

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

12-18 15 29V 57.654 ERROR [o.s.b.diagnostics.LoggingFailureAnalysisReporter]-

* *

APPLICATION FAILED TO START

* *

Description:

Field messageFeign in com.pance.scheduler.mdm.dataCenterTask.DataCenter required a bean of type 'com.pance.common.feign.MessageFeign' that could not be found.

The injection point has the following annotations:

-@ org.springframework.beans.factory.annotation.Autowired (required=true)

Action:

Consider defining a bean of type 'com.pance.common.feign.MessageFeign' in your configuration.

A very simple error message.

Look directly at Application and find and include the annotation @ EnableFeignClients, as well as @ ComponentScan ("com.pance"), and feign is also included in the com.pance directory.

I checked for a long time.

Finally, at the time of the most collapse, a detailed pit was found, which was introduced by feign in another common package. Although @ ComponentScan ("com.pance") specifies the scanning path that contains the path of feign, feign must add its own scanning range if it is not under the same module, for example

After @ EnableFeignClients (basePackages = "com.pance") is added, @ EnableFeignClients (basePackages = "com.pance") @ ComponentScan ("com.pance") @ EnableScheduling@SpringBootApplication (exclude = {DataSourceAutoConfiguration.class}) public class SchedulerApplication {public static void main (String [] args) {/ * only start one application*/ SpringApplication.run (SchedulerApplication.class, args);}}

If the jar package of Feign is under the same project as the service, you need to specify basePackage
