maven 打JAR包資源文件指定路徑與文件讀取

       

     1.配置RESOURCES節點

 有時會遇到maven打包后找不到資源文件了，其實這時候路徑發生了變化，為了確保打包后路徑不發生變化，指定一個固定的路徑，請看下面配置

<build>
  ...
  <resources>
    <resource>
      <filtering>true</filtering>
      <directory>src/main/command</directory>
      <includes>
        <include>run.bat</include>
        <include>run.sh</include>
      </includes>
      <targetPath>/abc</targetPath>
    </resource>
    <resource>
      <directory>src/main/scripts</directory>
    </resource>
  </resources>
  ...
</build>

2.讀取文件：

public static String path="resources/datatype.txt";

//String ss= App.class.getClassLoader().getResource("resources/datatype.txt").getPath();
			InputStream in = App.class.getClassLoader().getResourceAsStream(  
	                path);// 讀取流文件
			//File csv = new File(ss); // CSV文件
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            // 讀取直到最后一行 
            String line = ""; 
            //br.readLine();//跳過表頭
            while ((line = br.readLine()) != null) { 
                // 把一行數據分割成多個字段 
                //StringTokenizer st = new StringTokenizer(line, ",");
                String[] lin=App.DELIMITER.split(line.toString(),2);
                map.put(lin[0],lin[1]);
                
                System.out.println(line); 
            } 
            br.close();
