问题描述
在代码调适过程中，在Nacos中修改了文件上传的地址，但是在文件上传服务中读取出来的配置文件一直不会刷新，重启Nacos之后，修改之后的配置才生效
#文件上传配置
file:
# 文件上传目录
uploadFolder: E:/upload/
解决方法
我们需要在取此配置的代码处，加入注解@RefreshScope即可，如下：
package com.framework.pie.admin.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Configuration;
import org.springframework.util.ResourceUtils;
import java.io.File;
import java.io.FileNotFoundException;
@Configuration
@RefreshScope
public class UploadFileConfig {
@Value("${file.uploadFolder}")
private String uploadFolder;
public String getUploadFolder() {
if (uploadFolder == null){
File path = null;
try {
path = new File(ResourceUtils.getURL("classpath:").getPath());
} catch (FileNotFoundException e) {
e.printStackTrace();
}
if(!path.exists()) path = new File("");{
uploadFolder = path.getAbsolutePath();
}
}
return uploadFolder;
}
}
