maven 打JAR包资源文件指定路径与文件读取

       

     1.配置RESOURCES节点

 有时会遇到maven打包后找不到资源文件了，其实这时候路径发生了变化，为了确保打包后路径不发生变化，指定一个固定的路径，请看下面配置

<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.读取文件：

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

//String ss= App.class.getClassLoader().getResource("resources/datatype.txt").getPath();InputStream in = App.class.getClassLoader().getResourceAsStream(                  path);// 读取流文件//File csv = new File(ss); // CSV文件            BufferedReader br = new BufferedReader(new InputStreamReader(in));            // 读取直到最后一行             String line = "";             //br.readLine();//跳过表头            while ((line = br.readLine()) != null) {                 // 把一行数据分割成多个字段                 //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();
