spring Boot/batch通过代码禁用批处理自动启动

Question

我正在编写一个spring批处理应用程序，由需要按照特定顺序执行的不同作业组成。为此，我通过JobLauncher手动运行作业，并通过在属性文件中添加以下属性来禁用Spring批处理提供的自动启动特性：

spring.batch.job.enabled=false

Answer 1

@Bean
@ConditionalOnMissingBean
@ConditionalOnProperty(prefix = "spring.batch.job", name = "enabled", havingValue = "true", matchIfMissing = true)
public JobLauncherCommandLineRunner jobLauncherCommandLineRunner(
        JobLauncher jobLauncher, JobExplorer jobExplorer) {
    JobLauncherCommandLineRunner runner = new JobLauncherCommandLineRunner(
            jobLauncher, jobExplorer);
    String jobNames = this.properties.getJob().getNames();
    if (StringUtils.hasText(jobNames)) {
        runner.setJobNames(jobNames);
    }
    return runner;
}

这来自BatchAutoConfiguration。

据此判断，您可以尝试添加自己的JobLauncherCommandLineRunner实现，该实现不执行任何操作。这将影响@conditionalonmissingbean并且它不应该运行。
