java解析yaml_Java解析Yaml格式数据工具类

Yaml数据示例:

--- !ruby/hash:ActionController::Parameters

title: "测试这是一句文本文案,看看你的问题是否已经解决了呢?"

options:

- !ruby/hash:ActionController::Parameters

option_name: "已经解决了"

option_select: 'false'

- !ruby/hash:ActionController::Parameters

option_name: "还没解决呢"

option_select: 'true'

Yaml解析工具类:

import org.yaml.snakeyaml.Yaml;

import java.util.Map;

/**

* @description Yaml解析

*/

public class YamlUtil {

public static MapparseYaml2Map(String str){

Yaml yaml = new Yaml();

return (Map)yaml.load(cleanYaml(str));

}

private static String cleanYaml(String yamlText) {

String tmpText = yamlText.replaceAll("^---.*\n", "---\n");

tmpText = tmpText.replaceAll("!ruby.*\n", "\n");

return tmpText;

}

/**

* ignore

*/

private static boolean ignore(String yamlText) {

if (yamlText == null) {

return false;

}

return yamlText.matches("---.*\\{}\n") || yamlText.matches("---.*\\[]\n") || yamlText.matches("-.*\\{}\n") || yamlText.matches("-.*\\[]\n");

}

}

实战解析:

import java.io.IOException;

/**

public class TestYaml {

public static void main(String[] args) throws IOException {

String str = "--- !ruby/hash:ActionController::Parameters\n" +

"title: \"测试这是一句文本文案,看看你的问题是否已经解决了呢?\"\n" +

"options:\n" +

"- !ruby/hash:ActionController::Parameters\n" +

" option_name: \"已经解决了\"\n" +

" option_select: 'false'\n" +

"- !ruby/hash:ActionController::Parameters\n" +

" option_name: \"还没解决呢\"\n" +

" option_select: 'true'\n";

System.out.println(YamlUtil.parseYaml2Map(str));

}

}

解析结果:

{title=测试这是一句文本文案,看看你的问题是否已经解决了呢?, options=[{option_name=已经解决了, option_select=false}, {option_name=还没解决呢, option_select=true}]}
