从源代码里提取中文字符串的java类，中文java,工作中需要优化代码里的中

工作中需要优化代码里的中文警示语和异常信息，实在比较多，所以就写了个程序专门从代码里提取中文字符串。```javaimport java.io.;import java.util.;import java.util.regex.Matcher;import java.util.regex.Pattern;

/* * 搜索字符串并输出到控制台 /public class ExtractStr { public static String getHelpString(String[] args){ String result = String.format("%s [path]", new Object[]{"a"}); return result; }

private void getFiles(String rootPath, final String fileExt, List<File> fileList){    File f =new File(rootPath);    File[] list=f.listFiles(new FileFilter() {        @Override        public boolean accept(File f) {            boolean ret = f.isDirectory() || (f.isFile() && f.getName().endsWith(fileExt));            return ret;        }    });    for(File fn : list){        if (fn.isDirectory()){            this.getFiles(fn.getAbsolutePath(), fileExt, fileList);        }else{            fileList.add(fn);        }    }}public List<File> run(String rootPath, String fileExt){    List<File> result = new LinkedList<File>();    this.getFiles(rootPath, fileExt, result);    return result;}public List<String> parserSourceFile(List<String> patternList, File file, int miniCharCount) throws Exception {    List<String> result = new LinkedList<String>();    BufferedReader r = new BufferedReader(new FileReader(file));    char[] buffer = new char[(int)file.length()];    r.read(buffer, 0, (int)file.length());    String text=new String(buffer, 0, buffer.length);    for(String patternStr : patternList){        //Pattern pattern = Pattern.compile("\"(.*?)\"");        Pattern pattern = Pattern.compile(patternStr);        Matcher matchers= pattern.matcher(text);        while(matchers.find()){            String t=matchers.group();            if (t.length()>=miniCharCount)                result.add(t);        }    }    return result;}public static void main(String []args){    if (args.length==0){        StringBuilder sb = new StringBuilder()                .append("未传入需要搜索的有效的源代码路径")                .append("\n")                .append(ExtractStr.getHelpString(args));        System.out.println(sb.toString());        System.exit(1);    }    List<String> searchFolders=new ArrayList<String>(100);    for(int i=0; i<=args.length-1;i++){        File f=new File(args[i]);        if (!f.isDirectory() || !f.exists())            continue;        searchFolders.add(f.getAbsolutePath());    }    List<String> patternList = new LinkedList<String>();    patternList.add("'([\\u4E00-\\u9FA5]+)'");    patternList.add("\"([\\u4E00-\\u9FA5]+)\"");    ExtractStr es = new ExtractStr();    List<File> fileList = new ArrayList<File>(1000);    for(String sarchFolder : searchFolders){        List<File> t=es.run(sarchFolder, ".php");        fileList.addAll(t);    }    Set<String> outList=new HashSet<String>();    for(File f : fileList){        try{            List<String> items=es.parserSourceFile(patternList, f, 12);            outList.addAll(items);        }catch(Exception e){            e.printStackTrace();        }    }    for(String str : outList){        System.out.println(str);    }}

}```

对于拼接字符串的中文输出支持的不算好，而且也对中文的长度有限制（最少12个字符）
