Spring POI批量导出Excel，压缩zip,返回下载zip路径

了解springPOI导出excel

话不多，放码过来

application.yml配置文件

zipfilepath:
  #path: /export/data/www/zip
  path: E:\2345Downloads
  http: http://devh5.warehouseadmin.chujiayoupin.com/zip

配置zipFilePath

package com.warehouse.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;

@Component
@Primary
@ConfigurationProperties(prefix = "zipfilepath")//貌似zipfilepath这里只能小写
@Data
public class zipFilePath {

    private String path;

    private String http;
}

主要代码：

    @Autowired
    private zipFilePath zipFilPath;
