我有一个以下JSON字符串,我想在JSON字符串中找到/搜索条件。
1)。查找存在的键数。 2)。获取给定键的值(如果我们有数组)
{
"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
}
我正在寻找像Groovy GPath Syntax
这样的解决方案答案 0 :(得分:11)
您还可以使用JsonPath提供的REST Assured项目。此JsonPath项目使用Groovy GPath表达式。在Maven你可以这样依赖它:
<dependency>
<groupId>com.jayway.restassured</groupId>
<artifactId>json-path</artifactId>
<version>2.4.0</version>
</dependency>
<强>示例:强>
获取所有图书类别的列表:
List<String> categories = JsonPath.from(json).get("store.book.category");
获取第一本书类别:
String category = JsonPath.from(json).get("store.book[0].category");
获取最后一本书类别:
String category = JsonPath.from(json).get("store.book[-1].category");
获取价格在5到15之间的所有书籍:
List<Map> books = JsonPath.from(json).get("store.book.findAll { book -> book.price >= 5 && book.price <= 15 }");
GPath非常强大,您可以在路径表达式中使用更高阶函数和所有Groovy数据结构。

答案 2 :(得分:0)
首先,你必须添加依赖
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20090211</version>
</dependency>
然后你可以使用这段代码:
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import org.json.XML;
public class Main {
public static int PRETTY_PRINT_INDENT_FACTOR = 4;
public static String TEST_XML_STRING =
"<Result><ResultParameters><ResultParameter><Key>TransEndDate</Key><Value>20170731</Value></ResultParameter><ResultParameter><Key>Failed Reason</Key><Value>Operator 03058361178\03058365278 has no permission to perform the Check Balance service.</Value></ResultParameter><ResultParameter><Key>TransEndTime</Key><Value>123611</Value></ResultParameter></ResultParameters><ResultCode>2000</ResultCode><ResultType>0</ResultType><OriginatorConversationID>S_X20130129210125</OriginatorConversationID><ResultDesc>Initiator authentication error.</ResultDesc><TransactionID>000749213589</TransactionID><ConversationID>AG_20170731_00004c28e51f1f822e9e</ConversationID></Result>";
public static void main(String[] args) {
try {
JSONObject xmlJSONObj = XML.toJSONObject(TEST_XML_STRING);
String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
System.out.println(jsonPrettyPrintString);
System.out.println("Element="+xmlJSONObj.getJSONObject("Result").getInt("ResultCode"));
} catch (JSONException je) {
System.out.println(je.toString());
}
}
}
// in it i am searching an element which is present in a json object
答案 3 :(得分:0)
首先,在pom中添加json-path依赖
glTexImage2D
在基类中创建一个可以重用的实用程序:
<dependency>
<groupId>com.jayway.jsonpath</groupId>
<artifactId>json-path</artifactId>
<version>2.2.0</version>
</dependency>
使用此方法的一个示例:
public static String getValueFromJsonPath(String apiResponse, String jsonPath) {
return JsonPath.read(apiResponse, jsonPath);
}
注意:根据预期结果创建具有不同返回类型的重载方法(例如用于从json提取列表的列表)
