我无法将@Service bean注入到QuartzJobBean中。使用this question的技巧,我能够注入@Repository bean,但不能注入@Service bean。下面是我有:未能将@Service bean注入到QuartzJobBean中
一个仓库bean来访问MongoDB的文件:
public interface MyRepository extends MongoRepository<> {}
A服务bean来执行业务逻辑:
@Service
public class MyService {
@Autowired
private MyRepository myRepository;
public void method1() { ... }
}
我能够使用的MyService从Spring MVC控制器,所以我知道Spring正确地实例化了它们。
接下来,我创建了一个从QuartzJobBean延伸,并尝试注入的MyService到它工作:
<bean name="myJob" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass" value="com.MyJob" />
</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
[jobDetails and triggers omitted]
<property name="schedulerContextAsMap">
<map>
<entry key="myService">
<ref bean="myService"/>
</entry>
</map>
</property>
</bean>
有了这个配置,我'BeanCreationException: Cannot resolve reference to bean 'myService' while setting bean property 'schedulerContextAsMap'
如果我在schedulerContextAsMap改变“为myService”到' myRepository'它的工作。但是,我不想重新实现QuartzJobBean中的业务逻辑。
为什么myService bean对SchedulerFactoryBean不可见?顺便说一句,我已经启用了注释配置和组件扫描标签。
[更新 - 上下文初始化] 这里是我的web.xml,你可以看到spring-quartz.xml被最后引用了,所以一切都应该在它之前被初始化,不是吗?

如何,什么时候初始化应用程序上下文(S)?根据你的问题,最有可能的调度程序在实例化服务的上下文之前在上下文中被实例化。编辑您的问题以提供有关如何初始化上下文的详细信息。 – kaliatech
你说得对。我移动了我的spring-quartz.xml文件,现在schedulerFactory能够看到服务引用。谢谢。 – azgolfer
