Example 1 with JobBuilderFactory

use of org.springframework.batch.core.configuration.annotation.JobBuilderFactory in project Spring-Family by Sierou-Java.

the class Main method main.

public static void main(String[] args) {
    try {
        String[] configLocations = { "classpath*:applicationContext.xml" };
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext(configLocations);
        JobLauncher jobLauncher = applicationContext.getBean(JobLauncher.class);
        JobRepository jobRepository = applicationContext.getBean(JobRepository.class);
        PlatformTransactionManager transactionManager = applicationContext.getBean(PlatformTransactionManager.class);
        // 创建reader
        FlatFileItemReader<DeviceCommand> flatFileItemReader = new FlatFileItemReader<>();
        flatFileItemReader.setResource(new FileSystemResource("/project/Spring-Family-Parent/Spring-Family-Batch/src/main/resources/batch-data.csv"));
        // // 转换数据
        flatFileItemReader.setLineMapper(new DemoLineMapper());
        // 创建processor 对数据进行操作
        DemoProcessor helloItemProcessor = new DemoProcessor();
        // 创建writer
        FlatFileItemWriter<DeviceCommand> flatFileItemWriter = new FlatFileItemWriter<>();
        flatFileItemWriter.setResource(new FileSystemResource("/project/Spring-Family-Parent/Spring-Family-Batch/src/main/resources/batch-data.csv"));
        flatFileItemWriter.setLineAggregator(new DemoLineAggregator());
        // 创建Step
        StepBuilderFactory stepBuilderFactory = new StepBuilderFactory(jobRepository, transactionManager);
        Step step = stepBuilderFactory.get("step").<DeviceCommand, DeviceCommand>chunk(1).reader(// 读操作
        flatFileItemReader).processor(// 处理操作
        helloItemProcessor).writer(// 写操作
        flatFileItemWriter).build();
        // 创建Job
        JobBuilderFactory jobBuilderFactory = new JobBuilderFactory(jobRepository);
        Job job = jobBuilderFactory.get("job").start(step).build();
        // 启动任务
        jobLauncher.run(job, new JobParameters());
    } catch (JobExecutionAlreadyRunningException e) {
        e.printStackTrace();
