以编程方式将 txt 文件从 ANSI 转换为 UTF-8 [英] Converting a txt File from ANSI to UTF-8 programmatically

问题描述

我需要你的帮助.我正在开发一个将数据从 txt 文件转换为数据库的 Java 应用程序，问题是该文件具有 ANSI 编码，我无法更改，因为它来自我的应用程序外部，当我将数据写入数据库我得到了一些???"里面.我的问题是，如何将从文件中读取的数据从 ANSI 转换为可以处理那些 weired 符号的 UTF-8.我试过 Byte[] 到 String 的转换，但没有用.

I need your help here please. I'm working on a java application that convert data from a txt file into the database , The problem is that the file have ANSI encoding which i can't change because it comes from outside my application ,and when i write the data to the database i got some "???" inside. My question is , how can i convert the data that i read from the file from ANSI to UTF-8 which can handle those weired symbols. I've tried the Byte[] to String converting but it didn't work.

推荐答案

使用打开一个 像这样解码阅读器:

Reader reader = 
   new InputStreamReader(inputStream, Charset.forName(encodingName));

您应该使用哪种编码名称取决于哪种ANSI"编码文本文件是编写的中.您可以在此处 中找到Java 6 支持的编码列表.一>.如果是英文系统，很可能是windows-1252.

Exaclty which encoding name you should use depends on which "ANSI" encoding the text file was written in. You can find a list of encoding supported by Java 6 here. If it is an English-language system, it will likely be windows-1252.

正确地将数据写入数据库取决于正确配置数据库和(有时)为 JDBC 驱动程序提供正确的配置.

Writing data to the database correctly depends on configuring the database correctly and (sometimes) providing the right configuration to the JDBC driver.
