如何在 YAML 文件中为简单的 POJO 定义映射? [英] How to define a map in a YAML file for simple POJO?

问题描述

我正在使用snakeYaml 将某些配置/属性值解析为配置对象.

I am using snakeYaml to parse certain configuration/property values to a Configuration object.

我的 yaml 文件看起来像这样 -

My yaml file looks like this -

#Thread
batchLimit: 1000
threadCountLimit: 2

#Some More Config
key: value

#MAP
keyMapping: <What goes here?>

我的配置类看起来像这样 -

My Configuration class looks like this -

public class Configuration{
  int batchlimit;
  int threadCountLimit;
  ...
  Map<String,String> keyMapping;
}

如何在 YAML 文件中定义 keyMapping 使其直接通过 SnakeYAML 读取?

How do I define the keyMapping in the YAML file so it reads directly through SnakeYAML?

推荐答案

如下所示:

#MAP
keyMapping: 
    key1: value1
    key2: value2

通常 YAML 格式自然支持键值对.查看以下教程(仅作为示例):https://github.com/Animosity/CraftIRC/wiki/Complete-idiot's-introduction-to-yaml

Generally YAML format has natural support of key-value pairs. Take a look on the following tutorial (just for example): https://github.com/Animosity/CraftIRC/wiki/Complete-idiot's-introduction-to-yaml

或者只是谷歌yaml map"了解更多详情.
