瞭解springPOI匯出excel
話不多，放碼過來
application.yml配置檔案
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這裡只能小寫 @Data public class zipFilePath { private String path; private String http; }
主要程式碼：
