JSONPath.extract同一个parser只有第一次成功

[MASON-PRINCE]

请问 不同的JSONPath使用extract方法 提取同一个解析器的内容 第二次extract会得到null值 是BUG嘛 还是设定只能解析一次

@Test
    public void jsonPathTest() {
        String seatString = "{\n" +
                "\t\"flightId\":\"MH8633\",\n" +
                "\t\"column\":\"C\",\n" +
                "\t\"row\":\"19\"\n" +
                "}";
        JSONPath rowPath = JSONPath.of("$.row");
        JSONPath colPath = JSONPath.of("$.column");
        JSONReader parser = JSONReader.of(seatString);
        String row = (String)rowPath.extract(parser);
        String col = (String)colPath.extract(parser);
        System.out.println(row);
        System.out.println(col);
    }

要每次都new JSONReader，如下这样写：

    @Test
    public void jsonPathTest() {
        String seatString = "{\n" +
                "\t\"flightId\":\"MH8633\",\n" +
                "\t\"column\":\"C\",\n" +
                "\t\"row\":\"19\"\n" +
                "}";
        JSONPath rowPath = JSONPath.of("$.row");
        JSONPath colPath = JSONPath.of("$.column");
        String row = (String)rowPath.extract(JSONReader.of(seatString));
        assertEquals("19", row);

        String col = (String)colPath.extract(JSONReader.of(seatString));
        assertEquals("C", col);
    }

你用这个快照版本，支持如下写法

    @Test
    public void test2() {
        String seatString = "{\n" +
                "\t\"flightId\":\"MH8633\",\n" +
                "\t\"column\":\"C\",\n" +
                "\t\"row\":\"19\"\n" +
                "}";
        JSONPath path = JSONPath.of("$['row','column']");
        Object result = path.extract(
                JSONReader.of(seatString));
        assertNotNull(result);
        assertEquals("[\"19\",\"C\"]", result.toString());
    }

2.0.2版本预计明天发布
