【无标题】springboot java word模板导出下载
springboot 使用POI解决word模板导出下载
我这边例子是给定工单模板，根据业务要求查出来具体的工单信息，并填充到工单模板里面，然后再下载；具体实现代码如下
word模板
其中花括号表示占位符，里面字段代表需要映射的key值。模板写好之后放到系统自己设定的位置

最开始出现的问题是用poi实现word模板套打功能，本地windows环境可以实现，打包部署到linux报错，后来发现是因为项目打包之后会将模板乱码（报错ruxia），导致读取失败，解决方法把linux服务器上的模板删掉，重新上传到linux上目录位置。

其实是个小问题，最开始没有意识到是模板打包后出现了问题，希望可以当做参考
