修改配置文件

# 项目名

# 端口号

开启服务发现

在nacos中配置相关属性

创建命名空间
创建配置文件

在配置文件中添加AK等信息

alibaba.cloud.accessKey=LTAI5tKbSBpALoHC7JkBsF4g
alibaba.cloud.secretKey=AkpjpwVSqtiwQFyA66e2UAghxn6xK9
alibaba.cloud.oss.endpoint=oss-cn-beijing.aliyuncs.com
alibaba.cloud.bucket=exce-cui

创建接口

前段代码

如果不双向绑定图片不回加载

需要导入依赖才能开启bootrap.properties==

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bootstrap</artifactId>
            <version>3.1.2</version>
        </dependency>

使用@ConfigurationProperties注解配置元数据需要导入依赖

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>
