解析 YAML 文件

2022-01-14 00:00:00 yaml java

这是我第一次使用 YAML 文件，所以我首先想到的是找到任何可以帮助我解析文件的库.

This is the first time I am working with YAML files, so the first think I looked at was to find any library that could help me to parse the file.

我找到了两个库，YamlBean 和 SnakeYAML.我不确定我要使用哪一个.

I have found two libraries, YamlBean and SnakeYAML. I am not sure which one that I am going to use.

这是我尝试解析的文件示例:

Here is an example of the file that I am trying to parse:

users:
  user1:
    groups:
    - Premium
  user2:
    groups:
    - Mod
  user3:
    groups:
    - default
groups:
  Mod:
    permissions:
      test: true
    inheritance:
    - Premium
  default:
    permissions:
      test.test: true
    inheritance:
    - Mod
  Admin:
    permissions:
      test.test.test: true
    inheritance:
    - Mod

文件会动态变化，所以我不知道该文件将包含多少用户或组.

The file will change dynamical so I don't know how many users or groups the file would contain.

我想从中获取的信息是用户名和组，如下所示:

The information I would like to fetch from this is the user name and the group like this:

user1 Premium
user2 Mod
user3 default

从组中只有组名，如下所示:

And from the groups only the group names, like this:

Mod
default
Admin

谁能帮我从这里开始?什么是最好的图书馆?YamlBean 还是 SnakeYAML?

Anyone could get me started here? And what is the best library to use for this? YamlBean or SnakeYAML?

我想，我需要将信息保存在我可以轻松迭代的内容中.

I guess, I need to save the information in something that I easily could iterate over.

推荐答案

我最终使用了 SnakeYaml 并制作了一些拆分字符串来解决我的问题.

I ended up using SnakeYaml and made some split strings to solve my issue.

将yaml文件加载到Object中，然后加载到Map中，然后将Map中的结果拆分为String[] 然后在 for 循环中，我从 String[] 中读出名称.我对组也做了同样的事情.

Loaded the yaml file to Object and then into a Map, then split the result from the Map into String[] and then in a for loop I read out the name from the String[]. I did the same with groups.

我知道有更好的解决方案，但这对于这个项目来说已经足够了.

I know that there is better solutions out there but this is good enough for this project.

感谢大家的回复.
