Question

我正在寻找默认值Spring Batch Framework添加了作业＆＃34; BatchStatus＆＃34;基于＆＃34; EXITSTATUS＆＃34;的值（寻找defalut值框架添加）。我试着查看一些我没有找到的spring批处理框架类文件的源代码。可以请一些人发布类名，我可以在框架源代码中找到默认逻辑。

例如何时（模拟代码）

              if(EXITSTATUS is FAILED)
              {
                jobs.setBatchStatus(FAILED)
              }

Answer 1

1. Default Exit Status is UNKNOWN and Default Status is STARTING

    (org.springframework.batch.core.JobExecution)
    private volatile BatchStatus status = BatchStatus.STARTING;
    private volatile ExitStatus exitStatus = ExitStatus.UNKNOWN;

2. First time run is STARTED as

    org.springframework.batch.core.job.AbstractJob

    if (execution.getStatus() != BatchStatus.STOPPING) {
                    execution.setStartTime(new Date());
                    updateStatus(execution, BatchStatus.STARTED);

3. If your job is based on SimpleJob so
Job Status is updated based on Step Execution's Status (Note: they will apply upgrade status ) and
Job Exit Status is updated base on Step Execution's Exit Status

    org.springframework.batch.core.job.SimpleJob

        if (stepExecution != null) {
                    logger.debug("Upgrading JobExecution status: " + stepExecution);
                    execution.upgradeStatus(stepExecution.getStatus());
                    execution.setExitStatus(stepExecution.getExitStatus());
                }

4. If your job is based on FlowJob, Status and ExitStatus is updated based on the method

org.springframework.batch.core.job.flow.JobFlowExecutor

    public void updateJobExecutionStatus(FlowExecutionStatus status) {
            execution.setStatus(findBatchStatus(status));
            exitStatus = exitStatus.and(new ExitStatus(status.getName()));
            execution.setExitStatus(exitStatus);
        }

We are seeing Status and Exit Status are updating separately and no logic Spring set Status based on Exit Status. They are based on StepExecutionStatus or FlowExecutionStatus.

默认的Spring Job BatchStatus值基于EXITSTATUS
