使用 JAVA 中的 JSON 迭代 抛弃库.

Question

我有这个复杂的JSON数据从SalesForce到我的Java Spring应用程序。现在我想得到一些特定的值，如ID、Fund_Ops_Code__c、Type、Product_Type__c、Signed_Date__c、Signed_State__c等。但是 JSON 中没有模式。我必须在Java中使用Jettison库。有人可以帮我迭代这些值吗？

Answer 1

您可以使用java

JSON-Path库。 它具有强大的查询语言来搜索和检索特定的 JSON 对象和属性

    try (InputStream is = Files.newInputStream(Paths.get("C://temp/test.json"))) {
        // get all 'Product_Type__c' properties wherever they are
        JSONArray productTypes = JsonPath.read(is, "$..Product_Type__c");
        System.out.println(productTypes.get(0));
    } catch (Exception e) {
        e.printStackTrace();
    }

输出：

MAP Select Allocated

Answer 2

您可以使用org.json.simple(这是一个Google库(。它易于使用。

import org.json.simple.JSONObject;
public static void printJsonObject(JSONObject jsonObj) {
    for (Object key : jsonObj.keySet()) {
        //based on you key types
        String keyStr = (String)key;
        Object keyvalue = jsonObj.get(keyStr);
        //Print key and value
        System.out.println("key: "+ keyStr + " value: " + keyvalue);
        //for nested objects iteration if required
        if (keyvalue instanceof JSONObject)
            printJsonObject((JSONObject)keyvalue);
    }
}
