在类‘com.jayway.jsonpath. addOptions( com.jayway.jsonpath.Option )中找不到

Question

我在J抄JSR223采样器中运行下面的java代码时出错

import com.jayway.jsonpath.Configuration;
import com.jayway.jsonpath.JsonPath;
import com.jayway.jsonpath.Option;
import net.minidev.json.JSONArray;


String json = "{\"store\":{\"book\":[{\"category\":\"reference\",\"author\":\"Nigel Rees\",\"title\":\"Sayings of the Century\",\"price\":8.95},{\"category\":\"fiction\",\"author\":\"Evelyn Waugh\",\"title\":\"Sword of Honour\",\"price\":12.99},{\"category\":\"fiction\",\"author\":\"Herman Melville\",\"title\":\"Moby Dick\",\"isbn\":\"0-553-21311-3\",\"price\":8.99},{\"category\":\"fiction\",\"author\":\"J. R. R. Tolkien\",\"title\":\"The Lord of the Rings\",\"isbn\":\"0-395-19395-8\",\"price\":22.99}],\"bicycle\":{\"color\":\"red\",\"price\":19.95}},\"expensive\":10}";

        String jsonPath = "$..book[?(@.author == 'Nigel Rees')].title";

        Configuration config = Configuration.defaultConfiguration().addOptions(Option.DEFAULT_PATH_LEAF_TO_NULL);

        JSONArray authorsArr = JsonPath.using(config).parse(json).read(jsonPath);

        System.out.println(authorsArr.get(0).toString());

json 2.4.0.jar是在..\lib\ext下添加的，并假设它是自动加载到Jmeter上的。

上面的代码在IDE中签入并运行良好。

Answer 1

1. 将“语言”改为“groovy”，如果选择java，这不是真正的贝贝，而是贝贝

- is not fully Java-compliant
- has much worse performance comparing to Groovy

所以根据JMeter最佳实践，您应该从JMeter 3.1开始切换到JMeter。更多信息：为什么和如何使用它

1. 更改这一行： 字符串jsonPath = "$..book?(@.author == 'Nigel Rees').title"； 对这一个 字符串jsonPath = '$..book?(@.author == \'Nigel Rees\‘).title 由于您的Java语法与Groovy GString模板引擎略有冲突
2. 您不需要任何额外的.jars，代码将适用于普通的JMeter实例。

还请注意，Groovy有内置JSON支持
