springboot文件读取

1、读取本工程下的文件

@Autowired
    private ResourceLoader resourceLoader;

Resource resource = resourceLoader.getResource("classpath:\\file\\二标段.xlsx");

EasyExcelFactory.read(resource.getInputStream())

2、读取工程外的文件

boolean exists = Files.exists(Paths.get(opcProperties.getSectionOne()));

if (exists) {
                log.info("从{}读取数据", opcProperties.getSectionOne());

EasyExcelFactory.read(Files.newInputStream(Paths.get(opcProperties.getSectionOne())))
