@ConfigurationProperties读取配置文件内容

1.class

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

import java.util.List;

@Builder
@Data
@Component
@ConfigurationProperties(prefix = "chao")
public class ChannelListDTO {
    private List<ChannelDTO> list;
}

@Builder
@Data
@NoArgsConstructor
@AllArgsConstructor
public class ChannelDTO {
    private Boolean mg;
    private String fulfillmentMethod;
    private String segment;
    private String channel;
}

2.application-chao.yml

channel-management-list:
  list[0]:
    mg: true
    fulfillmentMethod: Direct
    segment: SMB,MM,ED,LE,GA,PS
    channel: 21
  list[1]:
    mg: true
    fulfillmentMethod: Indirect
    segment: SMB,MM,ED,LE,GA,PS
    channel: 11
  list[2]:
    mg: false
    fulfillmentMethod: Direct
    segment: MM,SMB
    channel: 71

3.使用时直接注入即可

 @Autowired
 private ChannelListDTO channelListDTO;


public void test(){
channelListDTO.getList();
}
