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;
toFile = args;
toSrcFile = args;
}
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
