打包成jar后,无法通过读取文件的方式读取jar包里面配置文件

DBApi类中 DBApi(DBConfig dbConfig)方法 我做了如下的尝试。

    public DBApi(DBConfig dbConfig) {

        this.dbConfig = dbConfig;

        try {

            String sqlContent;

            try {

                File sqlFile = ResourceUtils.getFile(this.dbConfig.getSql());

                sqlContent = FileUtils.readFileToString(sqlFile, StandardCharsets.UTF_8);

            } catch (Exception exception) {

                ClassPathResource sqlResource = new ClassPathResource(this.dbConfig.getSql());

                InputStream sqlInputStream = sqlResource.getInputStream();

                sqlContent = IOUtils.toString(sqlInputStream, Charsets.toCharset(StandardCharsets.UTF_8));

            }

            this.sqlMap = XmlParser.parseSql(sqlContent);
