Question

我正在使用 Spring Batch而不使用Spring Boot 来设置项目。创建Spring应用程序上下文后，将执行所有作业。

我尝试将spring.batch.job.enbled=false添加到 application.properties 以防止这种情况，但它仍无效。

还有其他方法可以阻止Spring在开始时执行作业吗？

主类：

package com.project.batch;
import ...    

@Configuration
@EnableBatchProcessing
@PropertySource("classpath:application.properties")
public class App {
    public static void main(String [] args) throws JobParametersInvalidException, JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException {
        System.out.println("starting main");

        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
        context.scan("com.project.batch");
        context.refresh();

        //JobParameters jobParameters = new JobParametersBuilder().toJobParameters();
        //JobLauncher jobLauncher = context.getBean(JobLauncher.class);
        //JobExecution execution = jobLauncher.run(context.getBean("loaderJob",Job.class),jobParameters);
        System.out.println("finished!!");
    }
}

工作班：

package com.project.batch;
import ... 

@Configuration
public class LoaderJobConfig {
    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    JdbcTemplate jdbcTemplate;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Bean
    public Job loaderJob(Step step1) throws Exception {
        System.out.println("Starting loaderJob");
        ...
    }
}

application.properties：

spring.batch.job.enbled=false
spring.batch.job.names=

运行日志：

编辑：从主类中删除了作业执行代码，作业仍然在上下文刷新时被触发

编辑2：包括运行日志

编辑3：修正了拼写错误和更新日志

Answer 1

Spring docs中提到的解决方案对我有用。我刚刚在application.properties中添加了一行，它在启动时停止了批处理作业的执行。

sed -i.bak '/LogFiles.txt$/s/^/##/'  Input_file

Answer 2

spring.batch.job.enabled = false

此配置适用于我

Answer 3

根据 Spring 文档，将以下行添加到 application.properties 对我来说效果很好：

spring.batch.job.enabled=false

在没有Spring Boot的情况下创建上下文后，防止Spring Batch自动作业触发
