您可以在启动Sping Boot 应用程序的main方法中添加启动作业的代码，类似于：

import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) throws Exception {
        ApplicationContext context = SpringApplication.run(DemoApplication.class, args);
        JobLauncher jobLauncher = context.getBean(JobLauncher.class);
        Job job = context.getBean(Job.class);
        jobLauncher.run(job, new JobParameters());
    }
}

字符串
另一种选择是将代码放在ApplicationRunner bean中。下面是一个示例：

import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
    @Bean
    public ApplicationRunner jobRunner(JobLauncher jobLauncher, Job job) {
        return args -> jobLauncher.run(job, new JobParameters());
    }
}
