我有我的应用程序-config.xml中定义如下，
...
<beans>
<bean id="serviceFactory" class="com.example.MyServiceFactory" />
<bean id="myAction" class="com.example.MyAction" scope="request">
<aop:scoped-proxy/>
</bean>
<bean id="myService" class="com.example.MyService" factory-bean="serviceFactory" factory-method="getService">
<constructor-arg type="java.lang.String" value="myServiceConfig" />
</bean>
</beans>
...
正如你所看到的，“myAction” bean是请求范围，在我MyAction文件我有以下几点。
public class MyAction
{
@Autowired
protected MyService myService;
}
...
有时候，并非总是如此，我看到的依赖性为myService的自动装配失败。 如果此有其他事情做我想不通，如果它在某些方面与我在应用程序的context.xml中定义的方法来做到。 有人能帮助我在这里？

春节日志说
