I am new to Spring batch and couldn't figure out how to do this..
Basically I have a spring batch files and both are have to run parallel i.e when I request execute_job1 then BatchConfig1 have to execute and when I request execute_job2 then BatchConfig2 have to execute. How can I do this?
Controller
#RestController
public class JobExecutionController {
#Autowired
JobLauncher jobLauncher;
#Autowired
Job job;
/**
*
* #return
*/
#RequestMapping("/execute_job1")
#ResponseBody
public void executeBatchJob1() {
}
/**
*
* #return
*/
#RequestMapping("/execute_job2")
#ResponseBody
public void executeBatchJob2() {
}
}
BatchConfig1
#Configuration
#EnableBatchProcessing
public class BatchConfig {
#Autowired
private JobBuilderFactory jobs;
#Autowired
private StepBuilderFactory steps;
#Bean
public Step stepOne(){
return steps.get("stepOne")
.tasklet(new MyTaskOne())
.build();
}
#Bean
public Step stepTwo(){
return steps.get("stepTwo")
.tasklet(new MyTaskTwo())
.build();
}
#Bean
public Job demoJob(){
return jobs.get("exportUserJob1")
.incrementer(new RunIdIncrementer())
.start(stepOne())
.next(stepTwo())
.build();
}
}
BatchConfig2:
#Configuration
#EnableBatchProcessing
public class BatchConfig2 {
#Autowired
public JobBuilderFactory jobBuilderFactory;
#Autowired
public StepBuilderFactory stepBuilderFactory;
#Autowired
public DataSource dataSource;
#Bean
public JdbcCursorItemReader<User> reader() {
JdbcCursorItemReader<User> reader = new JdbcCursorItemReader<User>();
reader.setDataSource(dataSource);
reader.setSql("SELECT id,name FROM user");
reader.setRowMapper(new UserRowMapper());
return reader;
}
public class UserRowMapper implements RowMapper<User> {
#Override
public User mapRow(ResultSet rs, int rowNum) throws SQLException {
User user = new User();
user.setId(rs.getInt("id"));
user.setName(rs.getString("name"));
return user;
}
}
#Bean
public UserItemProcessor processor() {
return new UserItemProcessor();
}
#Bean
public FlatFileItemWriter<User> writer() {
FlatFileItemWriter<User> writer = new FlatFileItemWriter<User>();
writer.setResource(new ClassPathResource("users.csv"));
writer.setLineAggregator(new DelimitedLineAggregator<User>() {
{
setDelimiter(",");
setFieldExtractor(new BeanWrapperFieldExtractor<User>() {
{
setNames(new String[] { "id", "name" });
}
});
}
});
return writer;
}
#Bean
public Step step1() {
return stepBuilderFactory.get("step1").<User, User>chunk(10).reader(reader()).processor(processor())
.writer(writer()).build();
}
#Bean
public Job exportUserJob() {
return jobBuilderFactory.get("exportUserJob2").incrementer(new RunIdIncrementer()).flow(step1()).end().build();
}
}
You can run a job with JobLauncher. The code for the controller:
#RestController
public class JobExecutionController {
public JobExecutionController(JobLauncher jobLauncher,
#Qualifier("demoJob") Job demoJob,
#Qualifier("exportUserJob") Job exportUserJob) {
this.jobLauncher = jobLauncher;
this.demoJob = demoJob;
this.exportUserJob = exportUserJob;
}
JobLauncher jobLauncher;
Job demoJob;
Job exportUserJob;
#RequestMapping("/execute_job1")
#ResponseBody
public void executeBatchJob1() {
try {
JobExecution jobExecution = jobLauncher.run(demoJob, new JobParameters(generateJobParameter()));
log.info("Job started in thread :" + jobExecution.getJobParameters().getString("JobThread"));
} catch (JobExecutionAlreadyRunningException | JobRestartException | JobParametersInvalidException | JobInstanceAlreadyCompleteException e) {
log.error("Something sent wrong during job execution", e);
}
}
#RequestMapping("/execute_job2")
#ResponseBody
public void executeBatchJob2() {
try {
JobExecution jobExecution = jobLauncher.run(exportUserJob, new JobParameters(generateJobParameter()));
log.info("Job started in thread :" + jobExecution.getJobParameters().getString("JobThread"));
} catch (JobExecutionAlreadyRunningException | JobRestartException | JobParametersInvalidException | JobInstanceAlreadyCompleteException e) {
log.error("Something sent wrong during job execution", e);
}
}
private JobParameters generateJobParameter() {
Map<String, JobParameter> parameters = new HashMap<>();
parameters.put("Job start time", new JobParameter(Instant.now().toEpochMilli()));
parameters.put("JobThread", new JobParameter(Thread.currentThread().getId()));
return new JobParameters(parameters);
}
}
To prevent starting your jobs at the application start add to the application.properties next spring batch configuration: spring.batch.job.enabled=false
I want to create an item reader, writer and processor for a Spring batch job using Gradle. I am having trouble with a few things. The delimited() portion is giving me an error. I am trying to read two fields for now: rxFname, rxLname.
Here is my code:
#Configuration
#EnableBatchProcessing
public class PaymentPortalJob {
private static final Logger LOG =
LoggerFactory.getLogger(PaymentPortalJob.class);
#Autowired
public JobBuilderFactory jobBuilderFactory;
#Autowired
public StepBuilderFactory stepBuilderFactory;
#Bean
MongoItemReader <PaymentAudit> fileReader(){
return new MongoItemReaderBuilder <PaymentAudit>()
.name("file-reader")
.targetType(PaymentAudit.class)
.delimited().delimiter(",").names(new String [] {"rxFname" , "rxLname"})
.build();
}
#Bean
public ItemProcessor<PaymentAudit, PaymentAudit> processor() {
return new PaymentAuditItemProcessor();
}
#Bean
public ItemWriter<PaymentAudit> writer() {
return new MongoItemWriterBuilder()<PaymentAudit>();
try {
writer.setTemplate(mongoTemplate());
}catch (Exception e) {
LOG.error(e.toString());
}
writer.setCollection("paymentAudit");
return writer;
}
#Bean
Job job (JobBuilderFactory jbf,
StepBuilderFactory sbf,
ItemReader<? extends PaymentAudit> ir,
ItemWriter<? super PaymentAudit> iw) {
Step s1 = sbf.get("file-db")
.<PaymentAudit, PaymentAudit>chunk(100)
.reader(ir)
.writer(iw)
.build();
return jbf.get("etl")
.incrementer(new RunIdIncrementer())
.start(s1)
.build();
}
#Bean
public MongoDbFactory mongoDbFactory() throws Exception {
return new SimpleMongoDbFactory(new MongoClient(), "db-name");
}
#Bean
public MongoTemplate mongoTemplate() throws Exception {
MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());
return mongoTemplate;
}
}
I have spring batch project I want to configure it on spring cloud dataflow I m able to register it on SCDF but on launching task my job is not running
following is my configuration file
#SpringBootApplication
#EnableBatchProcessing
#EnableTask
public class BatchApplication {
/*#Autowired
BatchCommandLineRunner batchcommdrunner;
#Bean
public CommandLineRunner commandLineRunner() {
System.out.println("Executed at :" + new SimpleDateFormat().format(new Date()));

can anyone help me to configure it properly or is there any other way where I can monitor my batch jobs
I also tried with Spring boot admin but it is not supporting java configuration in SBA is there any way to add jobs without jobs in xml
I am launcing this job from controller
JobParametersBuilder builder = new JobParametersBuilder();
System.out.println("Job Builder " + builder);
JobParameters jobParameters = builder.toJobParameters();
JobExecution execution = jobLauncher.run(job, jobParameters);
return execution.getStatus().toString();
This sample shows a basic Spring batch application that can be launched as a task in Spring Cloud Data Flow.
I created a Spring Boot with Spring Batch Application and Scheduling. When i create only one job, things are working fine . But when i try to create another job using the modular approach. The jobs and it's step are running many times and they are getting duplicated.
Getting the below error.

Can anyone Please guide me how to resolve these issues and run the jobs in a parallel way independent of each other ?

The map-based SimpleJobRepository created from MapJobRepositoryFactoryBean is not thread-safe.
From the Javadocs:
A FactoryBean that automates the creation of a SimpleJobRepository using non-persistent in-memory DAO implementations. This repository is only really intended for use in testing and rapid prototyping. In such settings you might find that ResourcelessTransactionManager is useful (as long as your business logic does not use a relational database). Not suited for use in multi-threaded jobs with splits, although it should be safe to use in a multi-threaded step.
You can create a JDBC-based SimpleJobRepository from JobRepositoryFactoryBean, which may utilize an in-memory H2 database if you don't require that Batch metadata be persisted.
Since you are using Spring Boot, to use an H2-backed JobRepository simply remove your JobRepository bean and add the following dependency to your pom.xml file:
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
Spring Boot will automatically configure a DataSource as though you had configured the following in your application.properties file and automatically use that DataSource in the creation of a JobRepository.
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
Alternatively, to use some other JDBC-backed JobRepository add the JDBC dependencies for your RDBMS of choice to your project, and configure a DataSource for it (either in code as a DataSource bean, or in application.properties using the spring.datasource prefix as shown above). Spring Boot will automatically use this DataSource during the creation of the JobRepository bean.
I'm tying to run the batch based on schedule.I have used scheduled annotation & cron expression. Batch is running only once. No error is getting displayed. I have added maven dependency for quartz.I have not added any XML file.
