java 本地txt文件 插入数据库中

Question

本地txt文件 txt的格式如下：
李四 123
张三 345
王五 789

现在要将本地拿到的.txt文件直接读取内容插入数据库中。

现在的疑问：是不是先要把本地文件上传到web工程下面的路径之后，才能读取？

       还是不需要路径，可以直接打开.txt文件，然后读取，插入数据库中？
       首先，我的txt的格式 有没有什么需要修改的？
       
       
       
         

Answer 1

If the web project and the .txt file are running on the same machine, they can be read directly using the absolute path.
If they are passed to the web project, they can be read using the relative path

Answer 2

1. You can upload it to the Web project, which means you can get the InputStream. So what should you do first to read the file? Take InputStream.
2. What can you do with the InputStream of txt? You can save the file and read its content. 3. You can read its content. Why not save it directly?

2. By reading a file on the hard disk, upload its content to the server, and the server directly reads the file content and stores it into the database. 3. Pass Read a file from the hard disk and upload its content to the server. The server first saves the file, then reads its content, and then saves it to the database
