java项目路径总结，java.io.File支持的路放方式

/**
     * FileOutpurStream以字节数组方式写入文件
     * @throws IOException
     */
    @Test
    public void testFileOutputStramBytes() throws IOException{
//        String path = "src/main/resources/write.data";
        String path = "write1.data";//在项目根目录创建
//        String localPath = "E:\\demo\\pdfCreat\\test.data";
        String localPath = "E:/demo/pdfCreat/test1.data";
        File file = new File(path);
        FileOutputStream fos = new FileOutputStream(file);
        fos.write("你好！".getBytes("utf-8"));
        fos.close();
    }
