java解析文件

遇到两个小坑：

1、使用String.split，部分分隔符需要转义：https://www.cnblogs.com/mingforyou/archive/2013/09/03/3299569.html

2、读取文件，报文件找不到：http://blog.51cto.com/632977922/1128981

3、java.io.FileNotFoundException: file:/home/admin/trunner/scenarios/64124/63844/target/larkPerf.jar!/data/getGoodsCategory.txt (没有那个文件或目录)

linux和windows文件夹分隔符不一样：

this.getClass().getClassLoader().getResource("data").getPath() + File.separator + "getGoodsCategory.txt"

public class FileUtils {

    public static List<String> file2List(String filePath) throws IOException {
        List<String> lines = new ArrayList();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(new FileInputStream(filePath)));
        String line;
        while (null != (line=bufferedReader.readLine())){
            lines.add(line);
        }
        return lines;
    }

    /**
     * 解析文件，返回mapList
     * @param filePath
     * @return
     * @throws IOException
     */
    public static List file2MapList(String filePath) throws IOException {
        List list = file2List(filePath);
        List mapList = new ArrayList();
        List<String> line,head = null;
        for (int i=0; i<list.size(); i++){
            Map<String, String> tmpMap = new HashMap();
            //第一行为表头 (二狗，直接用excel或xml吧，解析得这么费劲)
            if (0 == i){
                head = Arrays.asList(list.get(i).toString().split("\|"));
                continue;
            }
            line = Arrays.asList(list.get(i).toString().split("\|"));
            for (int j=0;j<line.size(); j++){
                tmpMap.put(head.get(j), line.get(j));
            }
            mapList.add(tmpMap);
        }
        return mapList;
    }

    @Test
    public void test(){
        try {
            List<String> list = file2List("D:\code\code-test\lark-perf\src\main\groovy\cn\com\ykse\perf\util\test.txt");
            System.out.println(list.get(0));
            List list1 = file2MapList("D:\code\code-test\lark-perf\src\main\groovy\cn\com\ykse\perf\util\test.txt");
            System.out.println(list1);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

=====2018-09-11补充=========
第3点找不到文件，是打成jar包后运行报错。一个项目中编译运行||引用jar包读取文件，方式不一样
引用jar包并读取该jar包文件时，应该用
this.getClass().getResourceAsStream(fileName)
