Question

我收到以下异常： ERROR [tomcat-http--39] (Controller.java:193) - Could not read [class java.lang.String]; nested exception is org.springframewor k.oxm.UnmarshallingFailureException: XStream unmarshalling exception; nested exception is com.thoughtworks.xstream.mapper.CannotResolveCl assException: response : response

代码本身非常简单，此调用可在邮递员中进行。

private boolean insertContactInSilverpop(String email, String token) throws ClientProtocolException, IOException {
    final String url = "https://api1.silverpop.com:443/rest/databases/...";
    String requestJson = new StringBuilder("{\"email\":\"")
            .append(email)
            .append("\",\"emailType\":\"HTML\",\"leadSource\":\"internal pop-up\",\"optInDetails\":\"User Name: name, IP Address: 0.0.0.0\"}")
            .toString();

    final HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Bearer " + token);
    headers.setContentType(MediaType.APPLICATION_JSON);

    HttpEntity<String> entity = new HttpEntity<String>(requestJson, headers);
    ResponseEntity<String> result = null;
    try {       
        result = restTemplate.postForEntity(url, entity, String.class);
        return result.getStatusCode() == HttpStatus.CREATED;                    
    }catch(Exception e){
        e.printStackTrace();
        log.error(e.getLocalizedMessage());
        return false;
    }
}

它成功插入数据，但在执行此操作时会引发异常。编辑：添加API响应：

{
"meta": {
    "attributes": {},
    "generalErrors": [],
    "fieldErrors": {},
    "links": [],
    "nextPageUrl": null
},
"data": {
    "location": "https://api1.silverpop.com/rest/databases/111/contacts/123",
    "id": 123
}

}

我最终通过旧的HttpURLConnection方法实现了这一目标，并且奏效了。万一有人碰到这是我的解决方案：

private boolean insertContactInSilverpop(String email, String tokenSp) throws ClientProtocolException, IOException {
    final String urlStr = "https://api1.silverpop.com:443/rest/databases/111/contacts";
    String requestJson = new StringBuilder("{\"email\":\"").append(email)
            .append("\",\"emailType\":\"HTML\",\"leadSource\":\"internal pop-up\",\"optInDetails\":\" IP Address: 0.0.0.0\"}").toString();

    byte[] postDataBytes = requestJson.getBytes("UTF-8");
    URL url = new URL(urlStr);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setDoOutput(true);
    conn.setInstanceFollowRedirects(false);
    conn.setRequestMethod("POST");
    conn.setRequestProperty("Content-Type", "application/json");
    conn.setRequestProperty("Authorization", "Bearer " + tokenSp);
    conn.setRequestProperty("charset", "utf-8");
    conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
    conn.setUseCaches(false);
    try (DataOutputStream wr = new DataOutputStream(conn.getOutputStream())) {
        wr.write(postDataBytes);
    }

    Reader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));

    StringBuilder sb = new StringBuilder();
    for (int c; (c = in.read()) >= 0;)
        sb.append((char) c);
    String response = sb.toString();

    log.info(response);
    int code = conn.getResponseCode();

    return code == 201;

}

错误：无法读取[class java.lang.String];嵌套的异常是org.springframework.oxm.UnmarshallingFailureException
