Example 1 with DemoProcessor

use of org.family.processor.DemoProcessor 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();
