springboot 動態給注解屬性參數賦值

這邊是結合最近開發的kafka功能加以示例

yml配置文件

spring:
  kafka:
    custom:
      topic: xxx
      groupId: oooo

配置映射的Java bean

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
 
/**
* @Author: shaww
* @Date:
*/
@Component
@ConfigurationProperties(prefix = "spring.kafka.custom")
@Data
public class KafkaCustomProperties {
    private String topic;
    private String groupId;
}

Controller里使用配置屬性進行注解動態設值

@Autowired
private KafkaCustomProperties kafkaCustomProperties;
 
@KafkaListener(topics = {"#{@kafkaCustomProperties.topic}"}, groupId = "#{@kafkaCustomProperties.groupId}")
public void listen(String message) {
}
