springboot读取配置文件值

依赖注入

 

1、非静态属性

   

@Configuration
@ConfigurationProperties("flow")
@Data
@Accessors(chain = true)
public class FlowConfig {
    /**
     * 账号
     */
    private String username;

 

 

@Configuration //放在类上



    // Redis服务器地址
    @Value("${spring.redis.host}")
    private String host;

2、静态属性

     需要添加set方法，而且set方法不能为静态

@Configuration

public class BIMUtils {
    private static String url;



    // 上传照片接口
    private static  String FILE_URL;
    //新增问题接口：
    private static  String ADD_URL;


    private static  String EDIT_URL;

    @Value("${bim.url}")
    public  void setUrl(String url) {
        BIMUtils.url = url;
        FILE_URL=BIMUtils.url+"/api/v1/files";
        ADD_URL=BIMUtils.url+"/api/v1/thirdpart/topics";
        EDIT_URL=BIMUtils.url+"/api/v1/thirdpart/topics/";
    }

 

    private static RocketmqLogMapper rocketmqLogMapper;

    @Resource
    public  void setRocketmqLogMapper(RocketmqLogMapper rocketmqLogMapper) {
        RocketMQUtil.rocketmqLogMapper = rocketmqLogMapper;
    }
