YAML 字符串对比合并：Java8 代码实现
要实现对比并合并两个yaml字符串，可以使用YAML库来解析和处理yaml格式的数据。以下是使用SnakeYAML库来实现的示例代码：
import org.yaml.snakeyaml.Yaml;
import java.util.HashMap;
import java.util.Map;
public class YamlMerger {
public static void main(String[] args) {
String yamlString1 = "deploy:\n" +
" url: 123456@.qq.com\n" +
" name: 123456\n" +
"swagger:\n" +
" enabled: ${swaggerEnabled:false}";
String yamlString2 = "server:\n" +
" port: 50012\n" +
" tomcat:\n" +
" uri-encoding: UTF-8\n" +
" servlet:\n" +
" context-path: /api/ts-dc\n" +

Yaml yaml = new Yaml();
Map<String, Object> yamlMap1 = yaml.load(yamlString1);
Map<String, Object> yamlMap2 = yaml.load(yamlString2);
// 对比并合并两个 YAML 字符串
yamlMap2.putAll(yamlMap1);
// 输出合并后的 YAML 字符串
System.out.println(yaml.dump(yamlMap2));
}
}
代码解释:
- 使用
Yaml库解析两个 YAML 字符串并将其转换为Map对象。 - 使用
putAll()方法将第一个 YAML 字符串中的内容合并到第二个 YAML 字符串中。 - 使用
dump()方法将合并后的Map对象转换为 YAML 字符串并输出。
注意:
- 此代码使用 SnakeYAML 库。如果使用其他 YAML 库，可能需要调整代码。
- 由于 YAML 字符串中的注释可能与键值对有换行符，所以需要使用
\n转义换行符。 - 此代码使用
putAll()方法进行合并，如果两个 YAML 字符串中存在相同键，则会覆盖第二个 YAML 字符串中的值。
通过以上代码，您可以成功对比并合并两个 YAML 字符串，并保留注释。
