I. Technologies
– Java 1.8
– Maven 3.3.9
– Spring Boot: 1.4.3.RELEASE
– Spring Tool Suite – Version 3.8.1.RELEASE
– MySQL Database
II. Overview
1. Introduction
For default, when running a restartable Batch Job, a step is executed if it was FAILED in a previous execution and do NOT be invoked if it was COMPLETED.
Spring Batch also supports some specific configuration for Steps when restart a Job.
– Setting a StartLimit: help control the number of times that a Step may be started.
1 2 3 |
<step id="step3"> <tasklet start-limit="${limitstart}" ref="taskletStep3"/> </step> |
– allow-start-if-complete: in case restartable Job, steps with the configuration allow-start-if-complete=”true” are always be invoked to run.
1 2 3 |
<step id="step2" next="step3"> <tasklet allow-start-if-complete="true" ref="taskletStep2"/> </step> |
2. Project Structure
In the tutorial, a Job will be created with 3 step: step1->step2->step3
– Step1 with no additional configuration
– Step2 is configured with allow-start-if-complete=”true”
– Step3 is configured with start-limit=”${limitstart}”
3. Step to do
– Create Spring Boot project
– Create Tasket for steps
– Configure Batch Job
– Implement Controller for Job Launcher
– Run & Enjoy Results
– How to manually restart a step when maximum start limit exceeded for step
III. Practice
1. Create Spring Boot project
– Open Spring Tool Suite, on main menu, choose File->New->Spring Starter Project, input project info. Press Next then Finish, a Spring Boot project will be created successfully.
Add needed dependencies:
– spring-boot-starter-web
– spring-boot-starter-batch
– mysql-connector-java

2. Create Tasket for steps
Create 3 Tasklet for 3 steps
TaskletStep1: clean resources. It will empty folder: folderpath=C:\\readfile.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 |

TaskletStep2: prepare data. It will create content for a file: filepath=C:\\readfile\\1.txt in case the file does Not exist before.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 |

TaskletStep3: processing data. It reads the file: filepath=C:\\readfile\\1.txt then shows content on console.

3. Configure Batch Job
Create a batchjob.xml file:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |

Enable BatchJob configuration in main class:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
package com.javasampleapproach.springbatch.restartstep; import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ImportResource; @SpringBootApplication @EnableBatchProcessing @ImportResource({"classpath:batchjob.xml"}) public class SpringBatchRestartStepConfigApplication { public static void main(String[] args) { SpringApplication.run(SpringBatchRestartStepConfigApplication.class, args); } } |
Configure appliation.properties file:
1 2 3 4 5 6 7 8 |
spring.datasource.url=jdbc:mysql://localhost:3306/testdb spring.datasource.username=root spring.datasource.password=12345 spring.batch.job.enabled=false limitstart=2 sleeptime=10000 filepath=C:\\readfile\\1.txt folderpath=C:\\readfile |
4. Implement Controller for Job Launcher
Implement a Controller for launching a Job:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
package com.javasampleapproach.springbatch.restartstep.controller; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.batch.core.Job; import org.springframework.batch.core.JobParameters; import org.springframework.batch.core.JobParametersBuilder; import org.springframework.batch.core.launch.JobLauncher; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; @RestController public class JobLauncherController { @Autowired JobLauncher jobLauncher; @Autowired Job job; @RequestMapping("/launchjob") public String handle(@RequestParam("jobId")String jobId) throws Exception { Logger logger = LoggerFactory.getLogger(this.getClass()); try { JobParameters jobParameters = new JobParametersBuilder().addString("jobId", jobId) .toJobParameters(); jobLauncher.run(job, jobParameters); } catch (Exception e) { logger.info(e.getMessage()); } return "Done!"; } } |
5. Run & Enjoy Results
Build & Run the project with Spring Boot App mode.
Step 3: Config: limitstart = 2 & sleeptime=10000
– Make request: http://localhost:8080/launchjob?jobId=1
Right after Step2 is completed, delete a file: C:\\readfile\\1.txt
Result: STEP1 & STEP2 are completed, STEP3 is failed because a file: C:\readfile\1.txt has been deleted.
Logs:

6. How to manually restart a step when maximum start limit exceeded for step
Solution 1: Reset start limit. In the case set: start limit = 3
– Restart the Job by above request again: http://localhost:8080/launchjob?jobId=1
Job is Completed with Logs:
1 2 3 4 5 6 7 8 9 10 11 12 |

Solution 2: Launch a new Job.
Make a request with jobId=2: http://localhost:8080/launchjob?jobId=2
Job is Completed with Logs:
