前置准备
1、电脑需要安装并配置JAVA开发环境
2、电脑需要下载安装JAR包转EXE工具
3、需要了解最基础的JAVA开发知识和，MAVEN项目构建知识
一、创建一个MAVEN工程
本次示范的DEMO功能要实现的功能非常简单，将一个文件夹下的文件的内容挨个复制，合并到一个文本中。
全部代码如下：
import org.fusesource.jansi.Ansi;
import org.fusesource.jansi.AnsiConsole;
import java.io.*;
import java.util.Scanner;
public class Main {
public static void main(String[] args) throws InterruptedException {
while (true) {
try {
String inputFolder;
Scanner sc = new Scanner(System.in);
if (args.length >= 1) {
inputFolder = args[0];
} else {
print("请输入需要合并的文本所在文件夹的目录(如 C:\\Users\\admin\\Desktop\\log)", Ansi.Color.CYAN);
inputFolder = sc.next();
}
File folder;
while (true) {
folder = new File(inputFolder);
if (!folder.exists() || !folder.isDirectory()) {
print("输入的不是一个文件夹路径或该文件夹不存在,请重新输入", Ansi.Color.RED);
inputFolder = sc.next();
} else {
break;
}
}
File output = new File(folder.getParent() + File.separator + "output.txt");
if (!output.exists()) {
output.createNewFile();
}
BufferedWriter bw = new BufferedWriter(new FileWriter(output));
File[] fs = folder.listFiles();
for (int i = 0; i < fs.length; i++) {
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(fs[i]), "UTF-8"));
String line;
while ((line = br.readLine()) != null) {
bw.write(line);
bw.newLine();
}
br.close();
}
bw.close();
print("合并完毕,合并的文本所在目录:" + output.getAbsolutePath(), Ansi.Color.GREEN);
} catch (IOException o) {
print("发生io异常,已终止程序", Ansi.Color.RED);
o.printStackTrace();
Thread.sleep(10000);
return;
}
}
}
public static Ansi formatStr(String content, Ansi.Color colour) {
return Ansi.ansi().fg(colour).a(content);
}
public static void print(String content, Ansi.Color colour) {
AnsiConsole.systemInstall();
System.out.println(formatStr(content, colour));
AnsiConsole.systemUninstall();
}
}
二、MAVEN打包配置
DEMO中引入了第三方的jar包，我们等下转成exe需要我们的jar包是带了完整库的，否则在别的环境运行会因为没有库报错，所以maven需要配置把第三方jar包一块打进去。
POM文件如下
