Failed to execute CommandLineRunner — fail to execute CommandLineRunner

A job instance already exists and is complete for the parameters = {- spring. The output. The ANSI. Enabled = always}. If you want to run this job again, change the parameters.

– job instance already exists, and completed the parameter = {- spring. The output. The ANSI. Enabled = always}. If you want to run this job again, change the parameter

look at the code:

package hoperun.pagoda.batchprocessingdata;

import java.util.Date;

import org.springframework.batch.core.ExitStatus;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.JobParametersBuilder;
import org.springframework.batch.core.configuration.JobRegistry;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan
@EnableAutoConfiguration
public class BatchprocessingdataApplication {
    public static void main(String[] args) {
        //        String jobName = args[0];
        String jobName = "userMigrationJob0";
        try {
            //System.out.println("节点1");
            ConfigurableApplicationContext context = SpringApplication.run(BatchprocessingdataApplication.class, args);
            JobRegistry jobRegistry = context.getBean(JobRegistry.class);
            Job job = jobRegistry.getJob(jobName);
            JobLauncher jobLauncher = context.getBean(JobLauncher.class);
            //System.out.println("节点2：");
            JobExecution jobExecution = jobLauncher.run(job, createJobParams());
            if (!jobExecution.getExitStatus().equals(ExitStatus.COMPLETED)) {
                throw new RuntimeException(jobName +" Job execution failed.");
            }
        } catch (Exception e) {
            throw new RuntimeException(jobName +" Job execution failed.");
        }
    }

    private static JobParameters createJobParams() {
        //System.out.println("节点3");
        return new JobParametersBuilder().addDate("date", new Date()).toJobParameters();
    }
}

I clearly set return new JobParametersBuilder(). AddDate (“date”, new date ()). ToJobParameters ();

. AddDate (“date”, new date ()) is different every time!! But why still report parameter same!!

solution:

adds the configuration in application.properties:

spring.batch.job.enabled=false

make both jobs unavailable and the program executes the job according to joblaunch.run.

error cause:

because each job is executed by default when spring batch is loaded, the default is to execute the job database first, and if the job is executed, an error is reported,

— this is printing

without spring.batch. Job.enabled =false

— this is printing

with spring.batch. Job.enabled =false
