将 Spring AOP 与 Quartz 调度程序结合使用
我在我的项目中使用 Quartz 调度程序来进行调度。我需要收集统计数据，例如作业运行的时间、持续时间和次数。我想使用 Spring AOP 来实现同样的目的。为此，我正在制作 Job 类 spring 管理的 bean。 Spring 为每个 Job 类创建一个 Proxy 类。但是现在，当 Quartz 尝试执行这个 spring 管理的作业时，我收到了 Spring 为该作业创建的 Proxy 类的 InstantiationException 异常。
org.quartz.SchedulerException：实例化类“$Proxy6”时出现问题 [请参阅嵌套异常：java.lang.InstantiationException：$Proxy6]
任何人都可以建议解决此问题的方法吗？
I am using Quartz scheduler for scheduling purposes in my project. I need to gather statistics like when, for how long, and how many times a job was run. I want to use Spring AOP for the same. For this, I am making Job classes spring-managed beans. Spring creates a Proxy class for each of the Job classes. But now when Quartz tries to execute this spring-managed Job, I am getting InstantiationException for the Proxy class created for the Job by Spring.
org.quartz.SchedulerException: Problem instantiating class '$Proxy6'
[See nested exception: java.lang.InstantiationException: $Proxy6]
Can anybody please suggest a solution for this problem?

如果你直接使用quarz（不通过Spring Schedule注释），你可以直接向quarz询问统计数据。 -- 其中许多已经在 quarz 中实现了。
If you use quarz directly (not via Spring Schedule annotation), you can ask quarz directly for the statistics. -- Many of them are already implemented in quarz.
因为Quartz Job类是由Quartz容器而不是Spring容器管理的，所以Spring AOP无法实现你的目标。出于您的目的，有两种方法可以实现此目的：
Quartz 具有内置侦听器机制，您可以使用全局侦听器来完成您想要的操作，就像 AOP 一样。关于监听器的更多信息，请参考：Quartz文档< /a>.
如果你坚持Spring AOP，你就必须自定义作业类实例化过程，让作业类由Spring容器来管理。一种方法是编写自己的 JobFactory，它扩展
SpringBeanJobFactory然后重写createJobInstance()方法。如果你想了解更多这方面的内容，请评论这个，我会写更多细节。Because Quartz Job class is managed by Quartz container not Spring container, Spring AOP can not achieve your goal. For your purpose, there are 2 ways that you can work on this:
Quartz has listener mechanism builtin, you can use a global listener to do want you want, as the AOP works. For more information about listener, refer to: Quartz document.
If you insist on Spring AOP, you have to customize the job class instantiation process, so that the job class is managed by Spring Container. One approach is write your own JobFactory, which extends
SpringBeanJobFactorythen override thecreateJobInstance()method. If you want more things about this, please comment on this, I will write more detail on this.
