Quartz作业中的Null applicationContext

Question

private ApplicationContext getApplicationContext(JobExecutionContext context ) throws Exception {

        System.err.println("check if variables are null - " + (context.getScheduler().getContext() == null));
        System.err.flush();

        ApplicationContext appCtx = (ApplicationContext)context.getScheduler().getContext().get(APPLICATION_CONTEXT_KEY);

        if (appCtx == null) {

            throw new JobExecutionException(

                    "No application context available in scheduler context for key /"" + APPLICATION_CONTEXT_KEY + "/"");

        }

        return appCtx;

    }

100%工作你可以尝试以下步骤。

1. 创建一个将实现ApplicationContextAware的类
2. 给出方法的实现
3. 创建ApplicationContext的静态变量
4. 在类中获取该变量

代码看起来会像。

public class ApplicationUtils implements ApplicationContextAware {

    private static ApplicationContext ctx;

    @Override
    public void setApplicationContext(ApplicationContext appContext)
            throws BeansException {
        ctx = appContext;

    }

    public static ApplicationContext getApplicationContext() {
        return ctx;
    }
}
