Question

我已经在jHipster服务器中配置了quartz作业，并且它适用于System.out.println语句但是当我尝试使用持久性相关的工作时它给了我一个例外。我有@Autowire JdbcTemplate jdbcTemplate;但它仍然是空的，原因是当jHipster服务器运行时它告诉：

 Scheduler meta-data: Quartz Scheduler (v2.2.1) 'schedulerFactoryBean' with instanceId **'NON_CLUSTERED'**
  Scheduler class: 'org.quartz.core.QuartzScheduler' - **running locally**.
  NOT STARTED.
  Currently in standby mode.
  Number of jobs executed: 0
  Using thread pool 'org.quartz.simpl.SimpleThreadPool' - with 10 threads.
  Using job-store 'org.quartz.simpl.RAMJobStore' - **which does not support persistence. and is not clustered**.

2017-09-26 10:56:10.523  INFO 10188 --- [  restartedMain] org.quartz.impl.StdSchedulerFactory      : Quartz scheduler **'schedulerFactoryBean' initialized from an externally provided properties** instance.
2017-09-26 10:56:10.523  INFO 10188 --- [  restartedMain] org.quartz.impl.StdSchedulerFactory      : Quartz scheduler version: 2.2.1
2017-09-26 10:56:10.523  INFO 10188 --- [  restartedMain] org.quartz.core.QuartzScheduler          : JobFactory set to: org.springframework.scheduling.quartz

这些是jhipster打印的日志，请告诉我如何使用jdbcTemplet的持久性我不想打开单独的JDBC连接。如果可能的话，我想使用现有的服务类，但也会出错。

以下是我的配置文件和作业文件

@Configuration
@ComponentScan("com.jobs")
public class QuartzJobSchedulerConf {
//http://www.concretepage.com/spring-4/spring-4-quartz-2-scheduler integration-annotation-example-using-javaconfig
//todo make common function for simple jobs to set attributes
//todo make common function for complex jobs to set attributes

    @Bean //this is simple job1
public MethodInvokingJobDetailFactoryBean methodInvokingJobDetailFactoryBean() {
    MethodInvokingJobDetailFactoryBean obj = new MethodInvokingJobDetailFactoryBean();
    obj.setTargetBeanName("jobone");
    obj.setTargetMethod("myTask");
    return obj;
}
@Bean
public SimpleTriggerFactoryBean simpleTriggerFactoryBean(){
    //This trigger will schedule the job after 3 seconds and repeat after every 30 seconds for 3+1 times.
    SimpleTriggerFactoryBean stFactory = new SimpleTriggerFactoryBean();
    stFactory.setJobDetail(methodInvokingJobDetailFactoryBean().getObject());
    stFactory.setStartDelay(3000);
    stFactory.setRepeatInterval(30000);
    stFactory.setRepeatCount(3);//todo repeat counter remove or use
    return stFactory;
}

@Bean //this is simple job2
public MethodInvokingJobDetailFactoryBean methodInvokingJobDetailFactoryBean2() {
    MethodInvokingJobDetailFactoryBean obj = new MethodInvokingJobDetailFactoryBean();
    obj.setTargetBeanName("jobtwo");
    obj.setTargetMethod("myTask");
    return obj;
}
@Bean
public SimpleTriggerFactoryBean simpleTriggerFactoryBean2(){
    SimpleTriggerFactoryBean stFactory = new SimpleTriggerFactoryBean();
    stFactory.setJobDetail(methodInvokingJobDetailFactoryBean2().getObject());
    stFactory.setStartDelay(3000);
    stFactory.setRepeatInterval(30000);
    stFactory.setRepeatCount(3);//todo repeat counter remove or use
    return stFactory;
}
@Bean//this is complex job1
public JobDetailFactoryBean jobDetailFactoryBean(){
    /*To pass the parameter to job by JavaConfig, we can have setter method and
    the property should be configured with setJobDataAsMap() in JobDetailFactoryBean
     configuration in JavaConfig*/
    JobDetailFactoryBean factory = new JobDetailFactoryBean();
    factory.setJobClass(SampleComplexJob.class);
    Map<String,Object> map = new HashMap<String,Object>();
    map.put("name", "RAM");
    map.put(SampleComplexJob.COUNT, 1);
    factory.setJobDataAsMap(map);
    factory.setGroup("mygroup");
    factory.setName("myjob");
    return factory;
}
@Bean
public CronTriggerFactoryBean cronTriggerFactoryBean(){
    CronTriggerFactoryBean stFactory = new CronTriggerFactoryBean();
    stFactory.setJobDetail(jobDetailFactoryBean().getObject());
    stFactory.setStartDelay(3000);
    stFactory.setName("mytrigger");
    stFactory.setGroup("mygroup");
    stFactory.setCronExpression("0 0/1 * 1/1 * ? *");
    return stFactory;
}

@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
    SchedulerFactoryBean scheduler = new SchedulerFactoryBean();
    scheduler.setTriggers(simpleTriggerFactoryBean().getObject(),
        simpleTriggerFactoryBean2().getObject(),
        cronTriggerFactoryBean().getObject());
    return scheduler;
}
}

有作业类代码

/*If we want to persist the changes in JobDataMap, we will annotate our class by @PersistJobDataAfterExecution */
@PersistJobDataAfterExecution

/*if there is more than one trigger which are scheduling same job then to avoid race condition, we have to annotate our job with @DisallowConcurrentExecution.*/
@DisallowConcurrentExecution

public class SampleComplexJob extends QuartzJobBean {

@Autowired
JdbcTemplate jdbcTemplate;

public static final String COUNT = "count";
private String name;
protected void executeInternal(JobExecutionContext ctx) throws JobExecutionException {

    for(String role:findRoleByPrivilegeSQLExample("PRIV_USER_SETTING")){
        System.out.println(role);
    }
    JobDataMap dataMap = ctx.getJobDetail().getJobDataMap();
    int cnt = dataMap.getInt(COUNT);
    JobKey jobKey = ctx.getJobDetail().getKey();
    System.out.println(jobKey+": "+name+": "+ cnt);
    cnt++;
    dataMap.put(COUNT, cnt);
}
public void setName(String name) {
    this.name = name;
}

public List<String> findRoleByPrivilegeSQLExample(String privilege){

    ///this is SQL example
    List<String> rolePrivilegesList = new ArrayList<String>();
    if(!privilege.isEmpty()){
        StringBuilder sql=new StringBuilder()
            .append("SELECT ID_ROLE FROM ROLE_PRIVILEGES WHERE ")
            .append("UPPER(ID_PRIVILEGE) = '")
            .append(privilege.toUpperCase()).append("'");
        rolePrivilegesList = jdbcTemplate.queryForList(sql.toString(),String.class);
    }
    return rolePrivilegesList;
}
}

如果在jhipster中有另一种配置Quartz作业的方法，请告诉我。或者，如果jHipster为Scheduler工作提供开箱即用的功能，那么它会很棒。

Quartz作业依赖

1）为什么我的bean没有被自动配置是因为它没有正确配置。

更新了课程的 QuartzJobSchedulerConf.java
