ClassPathResource踩坑

static {
    try {
        ClassPathResource resource = new ClassPathResource("ip2region.xdb");
        //获取真实文件路径
        String path = resource.getURL().getPath();
        byte[] cBuff = Searcher.loadContentFromFile(path);
        SEARCHER = Searcher.newWithBuffer(cBuff);
        log.info("加载了ip2region.xdb文件,Searcher初始化完成!");
    } catch (Exception e) {
        log.error("初始化ip2region.xdb文件失败,报错信息:[{}]", e.getMessage(), e);
        throw new RuntimeException("系统异常!");
    }
}

ClassPathResource resource = new ClassPathResource("ip2region.xdb");
InputStream inputStream = resource.getInputStream();
// 然后使用inputStream来读取数据
