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;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.cache.annotation.EnableCaching;
import@EnableConfigurationProperties({ SnmpPref.class })
public class Application {

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

application.yml

snmp:0/30 * * * * ?
  config:
    port: 161
    trapsPort:  162
    timeout:  3000
    maxRetries: 3
    isSnmp4JLogEnabled:  true

import org.springframework.beans.factory.annotation.Value;

使用方法:

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