spring+quartz定时任务配置---JobDetailBean

 之前有写过通过MethodInvokingJobDetailFactoryBean来实现定时任务

还有一种方式是JobDetailBean来实现定时任务

下面来看怎么配置

1.application.xml文件中（任务调度配置触发器）

<import resource="job/clearing/merfile/create_merfile.xml"/>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="reconFileCheckTrigger"/> <!-- 检查是否生成商户对账文件 -->
</list>
</property>
<property name="autoStartup" value="true"/>
</bean>

<!-- SpringBatch定时任务配置 -->
<batch:job-repository id="jobRepository" data-source="dataSource" transaction-manager="transactionManagerClear" isolation-level-for-create="REPEATABLE_READ" table-prefix="BATCH_" max-varchar-length="1000" />
<bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
<property name="jobRepository" ref="jobRepository" />
</bean>

2.create_merfile.xml

<!-- 调度触发器 -->
<bean id="reconFileCheckTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="reconFileCheckJobDetail" />
<property name="cronExpression" value="0 45 10 ? * *" />

</bean>
<!-- 配置调度程序quartz -->
<bean id="reconFileCheckJobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass" value="com.ninefbank.smallpay.clear.JobLauncherDetailsCommon" />
<property name="jobDataAsMap">
<map>
<entry key="job" value-ref="reconFileCheckJob" />
<entry key="jobLauncher" value-ref="jobLauncher" />
<entry key="jobParameterCommon" value-ref="jobParamsCheckFile" />
</map>
</property>
</bean>

<batch:job id="reconFileCheckJob" job-repository="jobRepository">
<batch:step id="reconFileCheckStep1">
<batch:tasklet ref="reconFileCheck"/>
</batch:step>
</batch:job>

<bean id="jobParamsCheckFile" class="com.ninefbank.smallpay.clear.JobParameterCommonChild" />

3.JobLauncherDetailsCommon.java

private static Logger logger = LoggerFactory.getLogger(JobLauncherDetailsCommon.class);
    private JobLauncher jobLauncher;
    private Job job;
    private JobParameterCommon jobParameterCommon;
    
    public void setJobLauncher(JobLauncher jobLauncher) {
        this.jobLauncher = jobLauncher;
    }
    public void setJob(Job job) {
        this.job = job;
    }
    public void setJobParameterCommon(JobParameterCommon jobParameterCommon) {
        this.jobParameterCommon = jobParameterCommon;
    }
    
    protected void executeInternal(JobExecutionContext context) {
        
        JobExecution result = null;
        try {
            result = jobLauncher.run(job, jobParameterCommon.getJobParametersFromJobMap());
            
        } catch (Exception e) {
            logger.error("执行job失败，job名称：{}", new Object[]{job.getName()}, e);
            throw new ApplicationException("执行job失败");
        }
        
        ExitStatus es = result.getExitStatus();
        String exitCode = es.getExitCode();
        if (ExitStatus.COMPLETED.getExitCode().equals(exitCode)) {
            logger.info("任务执行完成，job名称：{}；exitCode={}；exitDesc={}", new Object[]{job.getName(), exitCode, es.getExitDescription()});
            
        } else {
            logger.debug("任务执行失败，job名称：{}；exitCode={}；exitDesc={}", new Object[]{job.getName(), exitCode, es.getExitDescription()});
        }
    }

其实吧这两种呢都可以实现定时任务就是看执行的一个实在RAM中（第一种）一个是运行在RDB中（第二种），鄙人动手能力也不强，我也没试过只是看别人有这么解析的，参考文章可以看：
