springboot检测配置是否存在,如果存在则返回,不存在则提示新增

我这里是以七牛为例子

在yml中添加七牛的相关配置

 

qiniu: #七牛的相关配置
  accessKey: your_access_key
  secretKey: your_secret_key
  bucket: your_bucket_name
  domain: your_domain

 对应在给配置文件来一个相应的实体类QiniuConfig

@Component
@ConfigurationProperties(prefix = "qiniu")//获取配置
public class QiniuConfig {

    //七牛云提供的密钥对，用于身份验证
    private String accessKey;
    private String secretKey;
    //存储空间名称
    private String bucket;
    //存储空间绑定的域名
    private String domain;


    public String getAccessKey() {
        return accessKey;
    }

    public void setAccessKey(String accessKey) {
        this.accessKey = accessKey;
    }

    public String getSecretKey() {
        return secretKey;
    }

    public void setSecretKey(String secretKey) {
        this.secretKey = secretKey;
    }

    public String getBucket() {
        return bucket;
    }

    public void setBucket(String bucket) {
        this.bucket = bucket;
    }

    public String getDomain() {
        return domain;
    }

    public void setDomain(String domain) {
        this.domain = domain;
    }

    public QiniuConfig() {
    }

    public QiniuConfig(String domain, String bucket, String secretKey, String accessKey) {
        this.domain = domain;
        this.bucket = bucket;
        this.secretKey = secretKey;
        this.accessKey = accessKey;
    }
}

在补全相应的service

@Service
public class CommonServiceImpl {


    private final QiniuConfig qiniuConfig;

    @Autowired
    public CommonServiceImpl(QiniuConfig qiniuConfig) {
        this.qiniuConfig = qiniuConfig;
    }



    /**
     * 检查七牛云配置并返回相应信息。
     *
     * @return 如果配置存在，则返回配置信息；如果不存在，则提示添加配置。
     */
    public R<QiniuConfig> getQiniuConfig() {
        if (isQiniuConfigured()) {
            return R.success(qiniuConfig);
        } else {
            return R.error("请在配置文件中添加七牛云的相关配置。");
        }
    }

    /**
     * 检查是否已配置七牛云。
     *
     * @return 如果配置存在返回true，否则返回false。
     */
    private boolean isQiniuConfigured() {
        return qiniuConfig != null &&
                qiniuConfig.getAccessKey() != null && !qiniuConfig.getAccessKey().isEmpty() &&
                qiniuConfig.getSecretKey() != null && !qiniuConfig.getSecretKey().isEmpty() &&
                qiniuConfig.getBucket() != null && !qiniuConfig.getBucket().isEmpty() &&
                qiniuConfig.getDomain() != null && !qiniuConfig.getDomain().isEmpty();
    }

}

重点在这里

在补全相关的controller

/**
 * 公共配置controller
 */
@Controller
@ResponseBody
@RequestMapping("/commonConfig")
@Tag(name = "公共配置controller")
public class CommonController {

    @Autowired
    private CommonServiceImpl commonService;

    @Operation(summary = "获取七牛的相关配置", description = "获取七牛的相关配置")
    @GetMapping("/getQiniu")
    public R getQiniuConfig() {
        return commonService.getQiniuConfig();
    }


}

 最后测试
