苍颈辞で作った叠耻蹿蹿别谤别诲奥谤颈迟别谤に変えたら例外になった
- 3. ある日
- 4. 変更前 普通に生成していた val charset: String = … new BufferedWriter( new OutputStreamWriter( new FileOutputStream(new File("...")), charset ) )
- 5. 変更後 深く考えずnioのFiles.newBufferedWriterに変更 val charset: String = … Files.newBufferedWriter( Paths.get("..."), Charset.forName(charset) )
- 6. 例外発生
- 9. スタックトレース Failed to import XML. java.nio.charset.UnmappableCharacterException: Input length = 1 at java.nio.charset.CoderResult.throwException(CoderResult.java:282) at sun.nio.cs.StreamEncoder.implWrite(StreamEncoder.java:285) at sun.nio.cs.StreamEncoder.write(StreamEncoder.java:125) at java.io.OutputStreamWriter.write(OutputStreamWriter.java:207) at java.io.BufferedWriter.flushBuffer(BufferedWriter.java:129) at java.io.BufferedWriter.close(BufferedWriter.java:265)

- 14. こんなテストコードを用意 // 通常版 def normal() = { val charset = "EUC_JP" val data = "Java"+ "u3030" +"Scala" IO(new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("...")), charset))). using { writer => IO { writer.write(data) writer.flush() } } }
- 15. こんなテストコードを用意 // 通常版 def normal() = { val charset = "EUC_JP" val data = "Java"+ "u3030" +"Scala" IO(new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("...")), charset))). using { writer => IO { writer.write(data) writer.flush() } } } Javaで、EUC_JPで出力不可な文字
- 17. nioの場合 // nio版 def nio() = { val charset = "EUC_JP" val data = "Java"+ "u3030" +"Scala" IO(Files.newBufferedWriter(Paths.get("..."), Charset.forName(charset))).using { writer => IO { writer.write(data) writer.flush() } } }
