如何将数据传递给作为 MethodInvokingJobDetailFactoryBean 运行的方法？

我真正想做的是创建一个不同时运行的 Quartz 作业，但也可以访问 JobExecutionContext 以获得 previousFireTime。这是我的对象：

// imports...

public class UtilityObject {

    private SomeService someService;

    @Autowired
    public UtilityObject(SomeService someService) {
        this.someService = someService;
    }

    public void execute(JobExecutionContext ctx) throws JobExecutionException {
        Date prevDate = ctx.getPreviousFireTime();

        // rest of the code...
    }
}

这是我配置 bean 的方式：

<bean name="utilityBean" class="UtilityObject" />

<bean id="utilityJob"
    class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
   <property name="targetOjbect" ref="utilityBean" />
   <property name="targetMethod" value="execute" />
   <property name="concurrent" value="false" />
</bean>

<bean name="utilityTrigger"
    class="org.springframework.scheduling.quartz.SimpleTriggerBean">
    <property name="jobDetail" ref="utilityJob" />
    <property name="startDelay" value="5000" />
    <property name="repeatInterval" value="20000" />
</bean>

当我尝试运行它时，它在创建 bean 期间失败了

NoSuchMethodException：UtilityJob.execute()

有什么想法吗？

解决方案：

阅读斯卡夫曼的回答后，我能够让我的解决方案发挥作用。使用我拥有的触发器，我知道名称是，并发现默认组是“DEFAULT”。我让我的类扩展了 QuartzJobBean 类，然后添加了这段代码：

protected void executeInternal(JobExecutionContext ctx) 
               throws JobExecutionException {
    boolean isRunning = 
           (ctx.getScheduler().getTriggerState("utilityTrigger", "DEFAULT") ==
               Trigger.STATE_BLOCKED);

    if (isRunning) {
        // run the job
    }
}

抱歉，格式很奇怪；这些是一些很长的线！

What I'm really trying to do is create a Quartz job that doesn't run concurrently, but also can access the JobExecutionContext in order to get the previousFireTime. Here's my object:

// imports...

public class UtilityObject {

    private SomeService someService;

    @Autowired
    public UtilityObject(SomeService someService) {
        this.someService = someService;
    }

    public void execute(JobExecutionContext ctx) throws JobExecutionException {
        Date prevDate = ctx.getPreviousFireTime();

        // rest of the code...
    }
}

And here's how I've configured my bean:

<bean name="utilityBean" class="UtilityObject" />

<bean id="utilityJob"
    class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
   <property name="targetOjbect" ref="utilityBean" />
   <property name="targetMethod" value="execute" />
   <property name="concurrent" value="false" />
</bean>

<bean name="utilityTrigger"
    class="org.springframework.scheduling.quartz.SimpleTriggerBean">
    <property name="jobDetail" ref="utilityJob" />
    <property name="startDelay" value="5000" />
    <property name="repeatInterval" value="20000" />
</bean>

When I try to run this, it fails during the creation of the bean with

NoSuchMethodException: UtilityJob.execute()

Any ideas?

Solution:

After reading skaffman's answer, I was able to get my solution working. Using the trigger that I had, I knew that the name was, and figured out that the default group was 'DEFAULT'. I had my class extend the QuartzJobBean class, and then added this bit of code:

protected void executeInternal(JobExecutionContext ctx) 
               throws JobExecutionException {
    boolean isRunning = 
           (ctx.getScheduler().getTriggerState("utilityTrigger", "DEFAULT") ==
               Trigger.STATE_BLOCKED);

    if (isRunning) {
        // run the job
    }
}

Sorry for the weird formatting; these are some long lines!

可以使用参数属性将参数传递给 MethodInvokingJobDetailFactoryBean，其方式与使用 spring MethodInvokingFactoryBean 相同。

例如：

<bean id="myJob"
      class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="myBean" />
    <property name="targetMethod" value="myMethod" />
    <property name="arguments">
        <list>
            <value>greetings</value>
            <ref bean="anotherBean"/>
        </list>
    </property>
</bean>

It is possible to pass arguments to MethodInvokingJobDetailFactoryBean in the same way as with a spring MethodInvokingFactoryBean using the arguments property.

For example:

<bean id="myJob"
      class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="myBean" />
    <property name="targetMethod" value="myMethod" />
    <property name="arguments">
        <list>
            <value>greetings</value>
            <ref bean="anotherBean"/>
        </list>
    </property>
</bean>

MethodInvokingJobDetailFactoryBean 很方便，但很原始 - 它只能执行不带参数的公共方法。

如果您的作业需要访问 Quartz API，那么您需要使用 JobDetailBean 和 QuartzJobBean 而不是 MethodInvokingJobDetailFactoryBean。请参阅文档< /a> 获取说明。 QuartzJobBean 在运行时会传递当前的 JobExecutionContext。
