Java导出通过Word模板导出docx文件并通过QQ邮箱发送

一、创建Word模板

{{company}}{{Date}}服务器运行情况报告一、服务器：总告警次数：{{ServerTotal}}
服务器IP:{{IPA}}，总共告警次数:{{ServerATotal}} 
服务器IP:{{IPB}}，总共告警次数:{{ServerBTotal}} 
服务器IP:{{IPC}}，总共告警次数:{{ServerCTotal}} 二、应用程序：总告警次数{{ApplicationTotal}} 
服务器IP:{{IPA}}，包含{{ApplicationAName}}应用程序服务，总共告警次数：{{ApplicationATotal}}
服务器IP:{{IPB}}，包含{{ApplicationBName}}应用程序服务，总共告警次数：{{ApplicationBTotal}}
服务器IP:{{IPC}}，包含{{ApplicationCName}}应用程序服务，总共告警次数：{{ApplicationCTotal}}三、数据库：总告警次数{{DBTotal}} 
服务器IP:{{IPA}}，包含{{DBAName}}数据库，总共告警次数：{{DBATotal}}
服务器IP:{{IPB}}，包含{{DBBName}}数据库，总共告警次数：{{DBBTotal}}
服务器IP:{{IPC}}，包含{{DBCName}}数据库，总共告警次数：{{DBCTotal}}四、中间件：总告警次数{{MiddleWareTotal}} 
服务器IP:{{IPA}}，包含{{MiddleWareAName}}中间件，总共告警次数：{{MiddleWareATotal}}
服务器IP:{{IPB}}，包含{{MiddleWareBName}}中间件，总共告警次数：{{MiddleWareBTotal}}
服务器IP:{{IPC}}，包含{{MiddleWareCName}}中间件，总共告警次数：{{MiddleWareCTotal}} 五、接口：总告警次数{{InterfaceTotal}} 
服务器IP:{{IPA}}，包含{{InterfaceAName}}接口服务，总共告警次数：{{InterfaceATotal}}
服务器IP:{{IPB}}，包含{{InterfaceBName}}接口服务，总共告警次数：{{InterfaceBTotal}}
服务器IP:{{IPC}}，包含{{InterfaceCName}}接口服务，总共告警次数：{{InterfaceCTotal}}

将上述内容存入一个docx文件中，放到resources文件夹下

二、编写代码

工具类，主要读取信息并写入word模板内

import org.apache.poi.xwpf.usermodel.*;
import org.springframework.stereotype.Component;import java.util.List;
import java.util.Map;@Component

}
