间歇性NoSuchBeanDefinitionException

Question

我有一个小的Java库，该库带有少量@Components注释，并具有两个@configuration

，当我们从groovy脚本 SOMETIMES 中调用它时，出现以下错误。我不明白为什么这是一个间歇性问题

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'oms': Unsatisfied dependency expressed through constructor argument with index 0 of type [ component.oms.moegw.MqoegwMock]: : No qualifying bean of type [ component.oms.moegw.MqoegwMock] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

通过mvn执行的常规是：

import component.oms;
OmsService.acknoledgeOrder("123");

这是我们从groovy脚本中调用的Java类

package component.oms;

import component.oms.testdata.TestData;
import component.oms.config.MqoegwConfig;
import component.oms.config.OegwConfig;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public final class OmsServices
{
    private static AnnotationConfigApplicationContext ctx;

    static
    {
        init();
    }

    private OmsServices()
    {
        // static only
    }   

    public static void acknowledgeOrder(String orderId)
    {
        //load OMSMock context to be injected
        Oms oms = ctx.getBean(Oms.class);
        oms.acknowledgeOrder(orderId);
    }

    public static AnnotationConfigApplicationContext init()
    {
        ctx = new AnnotationConfigApplicationContext();

        ctx.register(component.oms.config.OegwConfig.class);
        ctx.register(component.oms.config.MqoegwConfig.class);
        ctx.register(component.oms.oss.OssMock.class);
        ctx.register(component.oms.Oms.class);
        ctx.refresh();
        return ctx;
    }
}

component.oms.moegw.MqoegwMock是一个注释为@Component的类（不要与component.oms.config.MqoegwConfig（@配置类）混淆

init()始终仅被调用一次，因为它是静态块。在我看来，这可能是某个类路径问题，或者我的静态类不是初始化该Java库的好方法？我不知道如何调试它。

提前感谢所有帮助

这里是用于说明的Oms类

@Component
public class Oms
{
    private MqoegwMock mqoegwMock;
    private OegwMock oegwMock;
    private OssMock ossMock;

    @Autowired
    public Oms(MqoegwMock mqoegwMock, OegwMock oegwMock, OssMock ossMock)
    {
        this.mqoegwMock = mqoegwMock;
        this.oegwMock = oegwMock;
        this.ossMock = ossMock;
    }

这里是MqoegwMock类，以供澄清

    @Component
    public class MqoegwMock
    {   

        private MessageProcessor messageProcessor;
        private OrderDao orderDao;

        @Autowired
        public MqoegwMock(MessageProcessor messageProcessor, OrderDao orderDao)
        {
            this.messageProcessor = messageProcessor;
            this.orderDao = orderDao;
        }
      ....
}

可能是由于不同的类加载器...正在调查
