Spring boot extracts the configuration of the service into the configuration file

1. Configuration file

monitor:
  # 采集服务端口
  port: 8010
  # 采集服务IP
  serverUrl: 10.10.24.169
  # 报警间隔
  timeInterval: 10000
  # 连续N秒未采集数据视为离线
  onlineTime: 10000

2. Configuration

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Data
@Component
@ConfigurationProperties(prefix = "monitor")// prefix中配置，必须与配置文件中的保持一致
public class MonitorServerConfig {
    // 属性无需加任何注解，只需要与配置文件中属性名保持一致即可
    private Integer port;//服务端口
    private String serverUrl;//服务IP
    private Long  timeInterval;//报警间隔
    private Long onlineTime;//连续N秒未采集数据视为离线
}

3. Configuration and use

@Component
public class MonitorServer {
    // 获取采集服务配置类
    private static MonitorServerConfig monitorServerConfig = SpringUtils.getBean(MonitorServerConfig.class);
    // 写方法，直接monitorServerConfig.属性名调用
}
