我正在使用Spring批处理和Spring数据jpa从日志文件中读取行并将其插入数据库中。但是它没有触发在logLineWriterService中写入方法，因此我无法弄清原因。贝娄是我到目前为止所做的。有人可以帮我吗？
public class Parser {
public static void main(String[] args) {
final ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext("/META-INF/spring/app-context.xml");
LogLineService service = (LogLineService) appContext.getBean(LogLineService.class);
try {
service.saveFileToDB("D:\\Other\\Suranga\\Remote\\Java_MySQL_Test\\access.log");
} catch (Exception e) {
e.printStackTrace();
}
}
}
