Posted 2020-11-05

报错如下：
Description:

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

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

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}" />

解决：
根据报错信息的提示，断定是 ref="checkPsptService"引用的有问题，在实现类上注解写的是：br/>@Service("CheckPsptService")
public class CheckPsptServiceImpl implements CheckPsptService{

Service注解和dubbo配置文件中引用的不一致，导致无法引用到。将spring-dubbo.xml中的ref和注解Service改为一致就可以了。
