ApplicationContext和Spring批处理的问题

Question

我正在使用 Spring Batch，我已经完成了批处理作业，并配置了 xml 文件， 我还将所有 Quartz 配置放入该 xml 文件中（触发器、schedulerFactoryBean 和 jobDetail）；这是一个java项目，我正在尝试加载应用程序上下文，作为主类中的独立项目；据文档所述，这应该使 Quartz 开始运行并正在执行此操作，问题是当作业使用触发器运行并调用服务时，就像所有 Autowired beans 尚未加载一样，所以给出我遇到了 NullpointerException... 这是触发器触发后作业调用的代码，当创建 JobParametersBuilder 时，一切都崩溃了，但 Quartz 仍在运行......

有人可以帮我解决这个问题吗？

//由作业

public class MainJobClass {

    private static Logger log = Logger.getLogger(MainJobClass.class);

    @Autowired
    private SimpleJobLauncher launcher;
    @Autowired
    private Job job;

    public void executeJob(){

        try{

            log.info("***** Staring job......");

            JobParametersBuilder builder = new JobParametersBuilder();
            builder.addDate("date", new Date());
            builder.addString("sendEmailJob", "Send email to approvers");
            JobParameters parameters = builder.toJobParameters();

            launcher.run(job, parameters);


        }catch(Exception e){
            log.error("Error on executing job"+e.fillInStackTrace());
        }
    }

    public void setLauncher(SimpleJobLauncher launcher) {
        this.launcher = launcher;
    }

    public void setJob(Job job) {
        this.job = job;
    }

简单主方法调用的类调用App context：

 public static void main(String[] args){      
ApplicationContext context  = new ClassPathXmlApplicationContext("/com/ge/grt/email/grt_email_send.xml");

          }

错误行：

INFO [DefaultQuartzScheduler_Worker-1] (MainJobClass.java:29) - ***** Staring job......
ERROR [DefaultQuartzScheduler_Worker-1] (MainJobClass.java:40) - Error on executing jobjava.lang.NullPointerException

这是xml文件上的Quartz bean：

<!-- Scheudler Factory bean, the job will run when the context is loaded -->
    <bean id="schedulerFactoryBean"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="beanTrigger"></ref>
            </list>
        </property>
    </bean>

    <!-- definition of the trigger -->
    <!-- defining the execution date: (once every week on monday at 8:00 AM) -->
    <bean id="beanTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="jobDetail" />
         <property name="misfireInstructionName" value="MISFIRE_INSTRUCTION_FIRE_ONCE_NOW"/> 
<!--         <property name="cronExpression" value="0 0 8 ? * MON" /> -->
        <property name="cronExpression" value="0 0/1 * * * ?" />
    </bean>


<!-- definiton of job detail bean -->
    <bean id="jobDetail"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="mainJobClass" />
        <property name="targetMethod" value="executeJob" />
        <property name="concurrent" value="false"></property>
    </bean>

尝试使用 org.springframework.scheduling.quartz.JobDetailBean 和 jobDataAsMap 来获取作业类 DI

Ex：
