查找和替换jobject中的值

import org.json.JSONObject;

public class JObjectUtils {
    public static void replaceValue(JSONObject jsonObject, String targetValue, String newValue) {
        for (String key : jsonObject.keySet()) {
            Object value = jsonObject.get(key);
            if (value instanceof JSONObject) {
                replaceValue((JSONObject) value, targetValue, newValue); // 递归处理嵌套的JSONObject
            } else if (value instanceof String && value.equals(targetValue)) {
                jsonObject.put(key, newValue); // 替换匹配的值
            }
        }
    }

    public static void main(String[] args) {
        JSONObject jsonObject = new JSONObject("{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}");
        System.out.println("Before replacement: " + jsonObject.toString());

        replaceValue(jsonObject, "New York", "San Francisco");

        System.out.println("After replacement: " + jsonObject.toString());
    }
}
