如何通过 javaconfig 使用 SchedulerFactoryBean.schedulerContextAsMap

我使用 Spring 4.0 并将项目从 xml 移至 java-config，除了访问@Service("scheduleService")带注释的类来自QuartzJobBean.executeInternal.

我必须让它工作的 xml 位是：

<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="schedulerContextAsMap">
        <map>
            <entry key="scheduleService" value-ref="scheduleService" />
            <entry key="knxUtil" value-ref="knxUtil" />
        </map>
    </property>
</bean>

然后，为了安排里面的Job@Service("scheduleService") I used:

JobBuilder jobBuilder = JobBuilder.newJob(ScheduledActionRunner.class)

此外，要实际执行Job我让它像这样工作：

@Component
public class ScheduledActionRunner extends QuartzJobBean {

    private KNXUtil         knxUtil;

    private ScheduleService scheduleService;

    public ScheduledActionRunner() {
    }

    @Autowired
    public void setScheduleService(ScheduleService scheduleService) {
        this.scheduleService = scheduleService;
    }

    @Autowired
    public void setKnxUtil(KNXUtil knxUtil) {
        this.knxUtil = knxUtil;
    }

    @Override
    public void executeInternal(JobExecutionContext context) throws JobExecutionException {

        JobDataMap jobDataMap = context.getMergedJobDataMap();

        String scheduleId = jobDataMap.getString("scheduleId");

        Schedule schedule = scheduleService.get(scheduleId);

        Set<ScheduledAction> actions = schedule.getScheduledActions();

        for (ScheduledAction scheduledAction : actions) {
            scheduledAction.getAction().execute(logger, knxUtil);
        }

    }

如上所述，所有这些都在使用 xml 配置时起作用。

现在，使用 java-config，它失败了NullPointerException at scheduleService.get(scheduleId);

对于java配置我设置了SchedulerFactoryBean像这样：

@Configuration
@PropertySource(value = "classpath:properties.${target_env:dev}.properties")
@ComponentScan(basePackages = { "com.example.smart" }
public class SpringRootApplication {

    @Autowired
    private ScheduleService scheduleService;

    @Autowired
    private KNXUtil         knxUtil;

    @Bean
    SchedulerFactoryBean schedulerFactoryBean() {

        SchedulerFactoryBean bean = new SchedulerFactoryBean();

        Map<String, Object> schedulerContextAsMap = new HashMap<String, Object>();
        schedulerContextAsMap.put("scheduleService", scheduleService);
        schedulerContextAsMap.put("knxUtil", knxUtil);

        bean.setSchedulerContextAsMap(schedulerContextAsMap);

        return bean;
    }
}

我怎样才能插入参考scheduleService在 - 的里面schedulerContextAsMap使用java配置？

我在这里找到了答案：https://stackoverflow.com/a/17394905/272180 https://stackoverflow.com/a/17394905/272180

解决方案是删除bean.setSchedulerContextAsMap(schedulerContextAsMap)设置时SchedulerFactoryBean，并修改executeInternal如下：

@Autowired
private KNXUtil         knxUtil;

@Autowired
private ScheduleService scheduleService;

@Override
public void executeInternal(JobExecutionContext context) throws JobExecutionException {

    // Adding this autowires everything as needed
    SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);

    JobDataMap jobDataMap = context.getMergedJobDataMap();

    String scheduleId = jobDataMap.getString("scheduleId");

    Schedule schedule = scheduleService.get(scheduleId);

    Set<ScheduledAction> actions = schedule.getScheduledActions();

    for (ScheduledAction scheduledAction : actions) {
        scheduledAction.getAction().execute(logger, knxUtil);
    }

}

这也简化了代码，因为@Autowired不再需要带注释的设置器。
