我有一些当前的代码,问题是它创建了一个1252代码页文件,我想强制它创建一个UTF-8文件
任何人都可以帮我这个代码,因为我说它目前有效...但我需要强制保存在utf ..我能传递一个参数或什么?
这就是我所拥有的,任何帮助都非常感激
var out = new java.io.FileWriter( new java.io.File( path )),
text = new java.lang.String( src || "" );
out.write( text, 0, text.length() );
out.flush();
out.close();

试试这个
Writer out = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream("outfilename"), "UTF-8"));
try {
out.write(aString);
} finally {
out.close();
}

不是使用FileWriter
,而是创建FileOutputStream
。然后,您可以将其包装在OutputStreamWriter
中,这允许您在构造函数中传递编码。然后,您可以将数据写入try-with-resources Statement:
try (OutputStreamWriter writer =
new OutputStreamWriter(new FileOutputStream(PROPERTIES_FILE), StandardCharsets.UTF_8))
// do stuff
}

尝试使用Apache Commons中的FileUtils.write
。
您应该可以执行以下操作:
File f = new File("output.txt");
FileUtils.writeStringToFile(f, document.outerHtml(), "UTF-8");
如果文件不存在,这将创建文件。

这里给出的所有答案都不会起作用,因为java的UTF-8写作被窃听了。

从Java 7开始,你可以更简洁地对Files.newBufferedWriter
做同样的事情:
Path logFile = Paths.get("/tmp/example.txt");
try (BufferedWriter writer = Files.newBufferedWriter(logFile, StandardCharsets.UTF_8)) {
writer.write("Hello World!");
// ...
}

var out = new java.io.PrintWriter(new java.io.File(path), "UTF-8");
text = new java.lang.String( src || "" );
out.print(text);
out.flush();
out.close();

Java 7 Files utility type对于处理文件非常有用:
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.io.IOException;
import java.util.*;
public class WriteReadUtf8 {
public static void main(String[] args) throws IOException {
List<String> lines = Arrays.asList("These", "are", "lines");
Path textFile = Paths.get("foo.txt");
Files.write(textFile, lines, StandardCharsets.UTF_8);
List<String> read = Files.readAllLines(textFile, StandardCharsets.UTF_8);
System.out.println(lines.equals(read));
}
}
Java 8 version允许您省略 Charset 参数 - 默认为UTF-8的方法。

我们可以使用java编写UTF-8编码文件 使用PrintWriter编写UTF-8编码的xml
或点击here
PrintWriter out1 = new PrintWriter(new File("C:\\abc.xml"), "UTF-8");

下面的示例代码可以逐行读取文件并以UTF-8格式写入新文件。另外,我明确指定了Cp1252编码。
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(
new FileInputStream("c:\\filenonUTF.txt"),
"Cp1252"));
String line;
Writer out = new BufferedWriter(
new OutputStreamWriter(new FileOutputStream(
"c:\\fileUTF.txt"), "UTF-8"));
try {
while ((line = br.readLine()) != null) {
out.write(line);
out.write("\n");
}
} finally {
br.close();
out.close();
}
}
