java讀取yaml配置文件

項目目錄結構:

app.yaml

appid: zrunframrwork
spring:
    application:
        name: zrunframrwork
    datasource:
        driverClassName: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost/test
server:
    port: 9000

測試代碼

		Yaml yaml = new Yaml();
		//文件路徑是相對類目錄(src/main/java)的相對路徑
		InputStream in = App.class.getClassLoader().getResourceAsStream("com/zrun/TestReadYamlFile/app.yaml");//或者app.yaml
		Map<String, Object> map = yaml.loadAs(in, Map.class);
		String appid = map.getOrDefault("appid", "123").toString();
		System.out.println(appid);
		String port = ((Map<String, Object>) map.get("server")).get("port").toString();
		System.out.println(port);
