Struts资源文件处理工具

一、创建置换工具

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URISyntaxException;

/**
* 字符转换工具
*/
public class Native2Ascii {
    private static String fromFile = null;
    private static String toFile = null;
    private static String toSrcFile = null;

    /**
     * 将字符串str中的非Ascii字符转换为\uFFFF格式
     *
     * @param str
     *            需要转换的字符
     * @return 转换结果
     */
    public static String toAscii(String str) {
        if (str.trim().startsWith("#"))
            return str;
        StringBuffer re = new StringBuffer();
        char[] chs = str.toCharArray();
        for (char c : chs) {
            if (c > 255)
                re.append("\\u" + Integer.toHexString(c));
            else
                re.append(c);
        }
        return re.toString();
    }

    /**
     * Native2Ascii 原文件 新文件路径
     *
     * @throws URISyntaxException
     */
    public static void main(String args[]) throws IOException,
            URISyntaxException {
        if (args == null || args.length == 0) {
            File file = new File(Native2Ascii.class.getResource("/N2A.ini")
                    .toURI());
            if (!file.exists()) {
                file.createNewFile();
                BufferedWriter writer = new BufferedWriter(new FileWriter(file));
                writer.write("#从资源文件");
                writer.newLine();
                writer.write("From File = ");
                writer.newLine();
                writer.write("#到资源文件");
                writer.newLine();
                writer.write("To File = ");
                writer.newLine();
                writer.write("#到本地源文件");
                writer.newLine();
                writer.write("Src File = ");
                writer.newLine();
                writer.close();
                System.out.println("配置文件不存在，以默认方式创建 \"N2A.ini\" 文件");
                return;
            } else {
                InputStream in = Native2Ascii.class
                        .getResourceAsStream("/N2A.ini");
                if (!readConfig(in))
                    return;
            }
        } else if (args == null || args.length != 3) {
            System.out.println("Native2Ascii 原文件 新文件路径");
            return;
        } else {
            fromFile = args[0];
            toFile = args[1];
            toSrcFile = args[2];
        }
        BufferedReader reader = new BufferedReader(new InputStreamReader(Native2Ascii.class.getResourceAsStream(fromFile)));
        BufferedWriter writer = new BufferedWriter(new FileWriter(new File(Native2Ascii.class.getResource(toFile).toURI())));
        BufferedWriter srcWriter = new BufferedWriter(new FileWriter(toSrcFile));
        String temp;
        while ((temp = reader.readLine()) != null) {
            temp=toAscii(temp);
            writer.write(temp);
            writer.newLine();
            srcWriter.write(temp);
            srcWriter.newLine();
        }
        reader.close();
        writer.close();
        srcWriter.close();
    }

    private static boolean readConfig(InputStream in) throws IOException {
        BufferedReader reader=new BufferedReader(new InputStreamReader(in));
        String temp,name,key;
        int index,line=0;
        while((temp=reader.readLine())!=null){
            line++;
            if(temp.trim().length()==0)continue;
            if(temp.trim().startsWith("#"))continue;
            if(temp.trim().startsWith("!"))continue;
            index=temp.indexOf("=");
            if(index==-1){
                System.out.println("Error: Line "+line+" is not format \"name=value\"");
                continue;
            }
            name=temp.substring(0, index).trim();
            key=temp.substring(index+1).trim();
            if(name.equalsIgnoreCase("From File")){
                fromFile=key;
            }else if(name.equalsIgnoreCase("To File")){
                toFile=key;
            }else if(name.equalsIgnoreCase("Src File")){
                toSrcFile=key;
            }
        }
        boolean ok=true;
        if(fromFile==null||fromFile.length()==0){
            ok=false;
            System.out.println("Error: \"From File\" value is NULL");
        }
        if(toFile==null||toFile.length()==0){
            ok=false;
            System.out.println("Error: \"To File\" value is NULL");
        }
        if(toSrcFile==null||toSrcFile.length()==0){
            ok=false;
            System.out.println("Error: \"Src File\" value is NULL");
        }
        return ok;
    }
}   

二、注意此工具的配置文件N2A.ini

#资源文件　的源文件
From File = /MyResources.txt
#Struts配置的资源文件
To File = /MessageResources.properties
#Struts配置的资源文件的源文件
Src File = src/MessageResources.properties

三、效果
/MyResources.txt　文件内容如下：

#全局信息
system.name = 影城管理系统
system.version = Vesion 1.0
system.copy = 2008-2020
page.title = 欢迎进入影城管理系统
type.null = 请求类型不能为空

运行置换工具得到文件：/MessageResources.properties  src/MessageResources.properties　文件内容如下：

#全局信息
system.name = \u5f71\u57ce\u7ba1\u7406\u7cfb\u7edf
system.version = Vesion 1.0
system.copy = 2008-2020
page.title = \u6b22\u8fce\u8fdb\u5165\u5f71\u57ce\u7ba1\u7406\u7cfb\u7edf
type.null = \u8bf7\u6c42\u7c7b\u578b\u4e0d\u80fd\u4e3a\u7a7a
