问题描述

Quartz怎么能不实现job接口而自己指定要执行的方法(就像sping中的那样)

如题

这次代码中没用到spring 因此以前在spring中用下列方式实现
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

run

的如今不能用了 怎么才能简单的做使得quartz直接调用自己指定的方法而不是
必须要继承Job实现execute()方法

解决方案

写一个代理类，包装下，在它的execute里面由它读取配置文件反射创建对象

解决方案二：

用动态代理出错了

我的实现

Job batchJob = new BatchJob();
    Job jobProxy = (Job) Proxy.newProxyInstance(batchJob.getClass().getClassLoader(),
            batchJob.getClass().getInterfaces(),
            new JobDetailInvocationHandler());

     JobDetail jobDetail = new JobDetail();
    jobDetail.setJobClass(jobProxy.getClass());
    jobDetail.setName(triggerPO.getTriggerName());
    jobDetail.setGroup(triggerPO.getTriggerGroupName());
    jobDetail.setDescription(triggerPO.getDescription());
    return jobDetail;
