获取不带class标签的Yaml字符串

Question

有没有一种方法可以使用yamlbeans库隐藏YamlWriter输出中的所有标记？

public <T> String toYaml(T object) {
    try (StringWriter stringWriter = new StringWriter()) {
        YamlWriter writer = new YamlWriter(stringWriter);
        writer.write(object);
        writer.getConfig().writeConfig.setWriteRootTags(false);//replaces only root tag
        writer.close(); //don't add this to finally, because it the text will not be flushed
        return removeTags(stringWriter.toString());
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}

private String removeTags(String string) {
    //a tag is a sequence of characters starting with ! and ending with whitespace
    return removePattern(string, " ![^\\s]*");
}

谢谢。

将写入器配置更改为从不写类名，这样就可以了：

writer.getConfig().writeConfig.setWriteClassname(YamlConfig.WriteClassName.NEVER);
