IOUtil.toString()丢失换行符

[simplecode101]

作者你好，不知道你最近还在不在更新，可能发现了一个bug
IOUtils的toString方法中使用的是BufferedReader的readLine方法，此方法会丢失每行的换行符，会导致yaml解析时报错，具体情况如下：
mapping values are not allowed here
in 'reader', line 1, column 29:
author: dumbcode projectName: test-1projectPath: D:\package ...
^

我的修复方式是在句末重新append，这样会让此方法改为默认拼接换行

你可以把读取yaml配置那个方法readConfigurationFromFile替换为这个

    private static void readConfigurationFromFile() {
        try {
            URL url = ConfigUtil.class.getClassLoader().getResource("generator.yaml");
            if (null == url || url.getPath().contains("jar")) {
                System.err.println("Can not find file named 'generator.yaml' under resources path, please make sure that you have defined that file.");
                System.exit(0);
            } else {
                Yaml yaml = new Yaml(new Constructor(Configuration.class));
                InputStream inputStream = ConfigUtil.class.getClassLoader().getResourceAsStream("generator.yaml");
                ConfigUtil.setConfiguration(yaml.load(inputStream));

            }
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(0);
        }
    }

感谢回复，不过这样改的话，作者在这块写的替换驼峰的代码逻辑就会被删掉了，不知道是不是因为我们版本不一样，我是master分支的最新代码：
