springboot中静态属性/静态方法从YAML(yml)读取配置属性

启动类添加注解@EnableConfigurationProperties

import jnetman.session.SnmpPref;

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);

使用方法:

...
this(targetDevice,SnmpPref.getUser(),SnmpPref.getPassword(),SnmpPref.getPrivacyDES());
...
