java实现word文件转html文件
作者:littleFatty
这篇文章主要为大家详细介绍了java实现word文件转html文件的方法,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
最近在项目开发中用户提出要在电脑上没有装office时在浏览器中打开word文件,最后确定的逻辑:用户选择想要查看的文件,页面js判断文件是否为word。不是执行下载,是后端根据word文件后缀访问对应转换方法。文件已存在对应html文件直接返回html文件地址,不存在先生成对应html文件再返回地址。js直接通过open()打开新的页签,展示word文件内容。新人一枚,如果代码中存在错误或有更好的实现万望指正!
