我有以下的URI,它返回給我一個JSON響應。
我試圖解析獲取請求的響應並訪問steps
數組,但它在第一步中停止。如何解析JSON REST響應 - NoClassDefFoundError:org/json/JSONArray
這裏是我的代碼:
public void getRoute() throws Exception {
String urlToRead="https://maps.googleapis.com/maps/api/directions/json?origin=41.43206,-81.38992&destination=Montreal&key=XXX";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet getRequest = new HttpGet(urlToRead);
getRequest.addHeader("accept", "application/json");
HttpResponse response = httpClient.execute(getRequest);
String json = IOUtils.toString(response.getEntity().getContent());
JSONArray array = new JSONArray(json);
for (int i = 0; i < array.length(); i++) {
JSONObject object = array.getJSONObject(i);
System.out.println(object.getJSONArray("routes"));
}
}
,但它與抱怨:
Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONArray
Maven的是:
<groupId>com.googlecode.json-simple</groupId>
<artifactId>json-simple</artifactId>
<version>1.1.1</version>
</dependency>

<groupId>org.apache.httpcomponents</groupId>

好像你已經錯過了jar文件在類路徑 – Arvind
的錯誤只是說你缺少運行時的依賴。你需要在類路徑中添加'json.jar' –
