最近在做HTML靜態(tài)生成，需要從硬盤上把模版文件的內(nèi)容讀出來。然后，替換相關(guān)標(biāo)簽寫到指定的文件中。無論是讀寫，都遇到了中文亂碼問題。試過多種方法，發(fā)現(xiàn)下面一種可以避免中文亂碼。（無論讀取還是寫入一定要進(jìn)行編碼轉(zhuǎn)換。）

1、JAVA讀取文件，避免中文亂碼。

/**
  * 讀取文件內(nèi)容
  *
  * @param filePathAndName
  *            String 如 c:\\1.txt 絕對路徑
  * @return boolean
  */
public static String readFile(String filePathAndName) {
  String fileContent = "";
  try { 
   File f = new File(filePathAndName);
   if(f.isFile()&&f.exists()){
    InputStreamReader read = new InputStreamReader(new FileInputStream(f),"UTF-8");
    BufferedReader reader=new BufferedReader(read);
    String line;
    while ((line = reader.readLine()) != null) {
     fileContent += line;
    }  
    read.close();
   }
  } catch (Exception e) {
   System.out.println("讀取文件內(nèi)容操作出錯(cuò)");
   e.printStackTrace();
  }
  return fileContent;
}

2、JAVA寫入文件，避免中文亂碼。

public static void writeFile(String filePathAndName, String fileContent) {
  try {
   File f = new File(filePathAndName);
   if (!f.exists()) {
    f.createNewFile();
   }
   OutputStreamWriter write = new OutputStreamWriter(new FileOutputStream(f),"UTF-8");
   BufferedWriter writer=new BufferedWriter(write);  
   //PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(filePathAndName)));
   //PrintWriter writer = new PrintWriter(new FileWriter(filePathAndName));
   writer.write(fileContent);
   writer.close();
  } catch (Exception e) {
   System.out.println("寫文件內(nèi)容操作出錯(cuò)");
   e.printStackTrace();
  }
}
