spring-batch-admin

问题 I am using Spring boot and Spring batch. I have defined more than one job. I am trying to build junit to test specific task within a job. Therefor I am using the JobLauncherTestUtils library. When I run my test case I always get NoUniqueBeanDefinitionException. This is my test class: @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = {BatchConfiguration.class}) public class ProcessFileJobTest { @Configuration @EnableBatchProcessing static class TestConfig {

问题 I am using Spring Batch and my step configuration is as below: @Bean public Step testStep( JdbcCursorItemReader<TestStep> testStageDataReader, TestStepProcessor testStepProcessor, CompositeItemWriter<Writer> testWriter, PlatformTransactionManager transactionManager, JobRepository jobRepository) { return stepBuilderFactory .get("TESTING") .<>chunk(100) .reader(testStageDataReader) .processor(testStepProcessor) .writer(testWriter) .faultTolerant() .skip(DataIntegrityViolationException.class)

问题 Background : We've some jobs managed by spring batch ( as boot application) triggered by cron job, I'm working to replace cron with quartz and add spring batch admin to manage jobs. So far I'm able to run the jobs via spring batch admin console, issue happens when quartz attempts to fire a job execution. JobLauncher, JobLocator objects are null which is autowired. Please note I use Java based configuration not XML. @PersistJobDataAfterExecution @DisallowConcurrentExecution @Component

问题 I have an issue with integrating the spring batch admin console into my application. The good news is that when i go to http://mymachine.com:8080/ReportingManager/batch/configuration I can get to the admin console. But when I go to http://mymachine.com:8080/ReportingManager/batch/job-configuration i get a 404 and an error saying that /batch/jobs can't be found. I've just gone through the exercise of comparing the difference in output of org.springframework.web logs between my application logs

问题 I'm trying to read some records from a database using loops then do some calculations on the records (updating a field called total). But i'm new to spring batch so please can anyone provide me with some tips. 回答1: this sounds like something the chunk pattern would address. you can use re-use existing Spring Batch components to read from the database, compose your own processor, then pass back to a Spring Batch component to store. say the use case is like this; - read a record - record

问题 Below is my configuration for spring batch remote chunking. My steps are running locally instead of remotely.

问题 I have integrated spring boot with spring-batch-admin successfully. I used the sample guide from spring-batch for setting up jobs. I added couple of more tasklets to the jobs. my UI shows only one job. I expect to see three of them. I also the expect the three jobs to have start/stop functionalities and take job parameters from UI. I have pushed entire code here.. please feel free to issue pull requests if you have solutions or improvements. Here is my job.xml located in src/main/resources
