java 如何设置文件流的编码格式代码如下, 我设置后还是SJIS格式的.我想问下怎么改能设置成utf-8

public static void CreateCsvfiles1(String targetPath, String filename,
List<JobBean> list) throws Exception {
File file = null;
OutputStream out = null;
PrintWriter pw = null;

OutputStreamWriter osw =null;
// PrintWriter pw = new PrintWriter(
// new OutputStreamWriter(
// new FileOutputStream("yourfilepath"),
// "UTF-8"));

try {
file = new File(targetPath + filename + ".csv");

if(file.exists()){
System.out.println("文件目录存在");
}else{
System.out.println("文件目录bu存在");
}
if(file.isFile()){
System.out.println("文件存在");
}else{
System.out.println("存在");
}

out = new FileOutputStream(file);

osw = new OutputStreamWriter(out,"utf-8");
System.out.println(osw+"aaaaaa");

pw = new PrintWriter(osw);
for (int j = 0; j < 6; j++) {
pw.append("TITLE" + ",");
}
for (int i = 0; i < list.size(); i++) {
String operationname = (list.get(i).getPaerationname());
String operationresult = (list.get(i).getOperationresult());
String username = (list.get(i).getUsername());
String userip = (list.get(i).getUereip());
String operationtime = (list.get(i).getOperationtime());
String operationdetail = (list.get(i).getOperationdetil());
pw.append("\n");
pw.append(operationname + ",");
pw.append(operationresult + ",");
pw.append(username + ",");
pw.append(userip + ",");
pw.append(operationtime + ",");
pw.append(operationdetail + ",");
}
} catch (Exception e) {
System.out.println(e.getMessage());
// TODO: handle exception
} finally {
System.out.println(targetPath + filename + ".csv");
pw.flush();
pw.close();
out.flush();
out.close();
osw.close();
}
}

OutputStreamWriter里指定charset应该就是这个用法，你确定List<JobBean>里的那些字符串都是正确的？你可以先作一个单元测试，自己在本地生成一些正确的JobBean，以保证问题不出在其他地方。
