使用Java将Excel文件导入Oracle表 [英] Importing Excel file into Oracle table using Java
问题描述
我是通过在屏幕上创建浏览选项来选择文件。
以下是您需要的解决方案的概述。
如果屏幕上的浏览选项是指网页上的HTML输入标签,如
< form>< input type =file>
您需要:
1 - 列表项
将excel文件(从浏览器)上传到服务器直接(http post)或使用更精细的东西,如文件上传器
2 - 在服务器上使用java,从Servlet的HttpRequest对象读取文件,例如, apache文件上传
从这一点起应该在一个java程序中访问一个带有文件内容的字节[]。
3 - 你现在可以读取文件:
- 作为字符串并假定它是CSV
- 或者使用像 Apache POI 这样的东西来阅读excel文件
4 - 解析文件内容后,您可以使用JDBC(使用Oracle jdbc驱动程序)连接到数据库并在数据表中插入数据。 p>
希望有帮助。
I have an excel file, which I need to import and load into an oracle table. Is there an API I can use in java to achieve this
I am selecting the file by creating a browse option on the screen.
Here's an overview of the solution you need.
If "browse option on the screen" means a HTML input tag on a web page like
<form><input type="file">
You will need to:
1 - List item Upload the excel file (from the browser) to the server directly (http post) or using something more elaborate like file uploader
2 - On the server, with java, read the file from the HttpRequest object of the Servlet using, for example, apache file upload
From this point you should be in a java program with access to a byte[] with the file content.
3 - You can now read the file:
- as String and assume it's CSV
- or use something like Apache POI to read the excel file
4 - After parsing the file content you can then use JDBC (with the Oracle jdbc driver) to connect to the db and insert the data in the tables.
Hope it helps.
