A component required a bean named ‘XXXService‘ ...

Description A component require could not be found Consider defining LifecycleException

報錯如下：
Description:

A component required a bean named ‘checkPsptService‘ that could not be found.

Action:
Consider defining a bean named ‘checkPsptService‘ in your configuration.

2018-05-15 14:46:21.539 ERROR 8652 --- [ina-startStop-1] org.apache.catalina.core.ContainerBase : A child container failed during start

java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/able_server]]......

配置spring-dubbo.xml：
<dubbo:service id="CheckPsptService"
interface="com.test.able.service.CheckPsptService" ref="checkPsptService"

timeout="${dubbo.timeout}" owner="${dubbo.application.owner}" group="${dubbo.service.group}" />

解決：
根據報錯信息的提示，斷定是 ref="checkPsptService"引用的有問題，在實現類上註解寫的是：@Service("CheckPsptService")
br/>@Service("CheckPsptService")

Service註解和dubbo配置文件中引用的不一致，導致無法引用到。將spring-dubbo.xml中的ref和註解Service改為一致就可以了。
