比Environment类好用很多，可以非常方便地进行类型转换,可以将属性绑定到对象,Map,List等类型上

# 绑定到对象  MailPropertiesC propertiesC = Binder.get(environment) //首先要绑定配置器      //再将属性绑定到对象上      .bind( "kaka.cream.mail-c", Bindable.of(MailPropertiesC.class) ).get(); //再获取实例        # 绑定Map  Map
   
     propMap = Binder.get(environment)      .bind( "fish.jdbc.datasource",Bindable.mapOf(String.class, Object.class) ).get();        # 绑定List  List
    
      list = Binder.get(environment)      .bind( "kaka.cream.list",Bindable.listOf(String.class) ).get();
    
   

例如:

// 绑定的类public class MultiKafkaProperties {
   	private Map
   
     producer;	private Map
    
      consumer;	// getter	// setter}
    
   

# 配置kafka.producer.server=127.0.0.1:9093kafka.producer.username=kafkakafka.producer.password=passwordkafka.producer.topic=topic1kafka.consumer.server=127.0.0.1:9093kafka.consumer.username=kafkakafka.consumer.password=passwordkafka.consumer.topic=topic1kafka.consumer.group.id=group1kafka.consumer.poll.ms=3000kafka.consumer.max.poll.records=300

// 绑定Binder binder = Binder.get(environment);MultiKafkaProperties config = binder.bind("kafka", MultiKafkaProperties.class).get();
