注解@Value获取配置文件内容 (demo)

1. 自定义配置文件内容 (application.yml)

 

2. 使用 @Value("${xxx}") 注入属性

import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class ConstantPropertiesUtils implements InitializingBean {

    @Value("${aliyun.oss.file.endpoint}")
    private String endpoint;

    @Value("${aliyun.oss.file.keyid}")
    private String keyId;

    @Value("${aliyun.oss.file.keysecret}")
    private String keySecret;

    @Value("${aliyun.oss.file.bucketname}")
    private String bucketName;

    @Value("${aliyun.oss.file.cdn}")
    private String cdn;

    //定义公开静态常量
    public static String END_POIND;
    public static String ACCESS_KEY_ID;
    public static String ACCESS_KEY_SECRET;
    public static String BUCKET_NAME;
    public static String CDN;

    @Override
    public void afterPropertiesSet() throws Exception {
        END_POIND = endpoint;
        ACCESS_KEY_ID = keyId;
        ACCESS_KEY_SECRET = keySecret;
        BUCKET_NAME = bucketName;
        CDN = cdn;
    }
}
