我有一个弹簧批量集成的spring mvc应用程序。我的春季批处理作业通过cron触发器执行。
我的xml中有两个批处理作业。第二批作业工作正常，但是当我执行第一个批处理作业时，它执行第二个。
我认为我正在错误地注册我的工作。有人可以帮我解决可能出错的问题。
感谢
第二个作业定义（job-bulletin-bar-msg-update.xml）...
<job id="job-bulletin-bar-msg-update" xmlns="http://www.springframework.org/schema/batch">
<step id="step1">
<tasklet>
<chunk
reader="bulletinBarUpdateJdbcCursorItemReader"
writer="bulletinBarUpdateItemWriter"
commit-interval="1000" />
</tasklet>
</step>
</job>
第一个职位定义（job-daily-tran-counts.xml）......
<job id="job-daily-tran-counts" xmlns="http://www.springframework.org/schema/batch">
<step id="step1">
<tasklet>
<chunk
reader="dailyTranCountJdbcCursorItemReader"
writer="dailyTranCountItemWriter"
commit-interval="1000" />
</tasklet>
</step>
</job>
向调度程序和注册表添加作业....
<beans profile="pre,prod">

这是我的工作启动器详细信息类。我只是从其他地方复制了它......
public class JobLauncherDetails extends QuartzJobBean {
static final String JOB_NAME = "jobName";
private JobLocator jobLocator;
private JobLauncher jobLauncher;
public void setJobLocator(JobLocator jobLocator) {
this.jobLocator = jobLocator;
}
public void setJobLauncher(JobLauncher jobLauncher) {
this.jobLauncher = jobLauncher;
}
@SuppressWarnings("unchecked")
protected void executeInternal(JobExecutionContext context) {
Map<String, Object> jobDataMap = context.getMergedJobDataMap();
String jobName = (String) jobDataMap.get(JOB_NAME);
JobParameters jobParameters = getJobParametersFromJobMap(jobDataMap);
try {
jobLauncher.run(jobLocator.getJob(jobName), jobParameters);
} catch (JobExecutionException e) {
e.printStackTrace();
}
}
//get params from jobDataAsMap property, job-quartz.xml
private JobParameters getJobParametersFromJobMap(Map<String, Object> jobDataMap) {
JobParametersBuilder builder = new JobParametersBuilder();
for (Entry<String, Object> entry : jobDataMap.entrySet()) {
String key = entry.getKey();
Object value = entry.getValue();
if (value instanceof String && !key.equals(JOB_NAME)) {
builder.addString(key, (String) value);
} else if (value instanceof Float || value instanceof Double) {
builder.addDouble(key, ((Number) value).doubleValue());
} else if (value instanceof Integer || value instanceof Long) {
builder.addLong(key, ((Number) value).longValue());
} else if (value instanceof Date) {
builder.addDate(key, (Date) value);
} else {
// JobDataMap contains values which are not job parameters
// (ignoring)
}
}
//need unique job parameter to rerun the same job
builder.addDate("run date", new Date());
return builder.toJobParameters();
}
}
这是我的batch.properties ...

更多信息。为了尝试找到更多信息，我在org.springframework.batch.core.launch.support.SimpleJobLauncher上登录。

我有类似的问题。对我有用的是重命名step-id以使它们是唯一的。值得一试
答案 1 :(得分：0)
我有一个类似的问题，这是运行于Spring Boot版本2.1.10.RELEASE的spring批处理版本4.2.1.RELEASE，该版本由spring framework版本5.1.11.RELEASE支持。因此，这里（可能）存在一种情况，当框架“不平等地被当代人束缚”时会发生什么。要考虑的另一件事是作业存储库的持久性，这意味着在某些时候该作业将调用错误的步骤。这花费了很多调试中断点，尤其是在作业启动器周围。因此，我所做的是任意更改步骤的名称。在我的假设中，这将迫使框架检测步骤ID的更改并刷新数据库中的定义。有效。如果我坚持使用spring boot的spring batch版本，是否还在寻找step-id-name-calling问题是否可以解决自己的问题。
答案 2 :(得分：0)
我遇到了同样的问题，不得不重命名所有步骤。
在某处阅读 @EnableBatchProcessing（modular = true）
这可能会使作业保持在单独的“上下文”中
