我在一个restapi客户机上工作,我有一个类负责所有的请求指令,因为我将使用完全相同的提供者。我目前能够发送,接收和处理的答复,只要他们是200确定。但是,一旦我开始接收到与之不同的内容,就会出现错误,程序就会停止运行。

根据证据你可以看到我得到的答复正文,我能够打印出来,不幸的是,我不能传递给下一个类。
这是我用来获取数据的方法:

public AdvanceSmsDlrResponse getDeliveryReport() {

        AdvanceSmsDlrResponse dlrResponse = new AdvanceSmsDlrResponse();
        try {
            dlrResponse = objectMapper.readValue((String) requestExecutor(null, "/sms/1/reports", HttpMethod.GET,
                    "com.infobipcommunity.models.responses.sms.getDeliveryReport.AdvanceSmsDlrResponse"), AdvanceSmsDlrResponse.class);
            return null;
        } catch (JsonProcessingException e) {
            e.printStackTrace();
            return new AdvanceSmsDlrResponse();
        }
    }

在上一个代码段中调用的泛型方法:

public Object requestExecutor(Object requestBody, String requestPath, HttpMethod httpMethod, String className) {

    entity = new HttpEntity<>(requestBody, httpHeaders);
        response = requestRestTemplate.exchange(getUrlhost() + requestPath, httpMethod, entity, className.getClass());
        LOGGER.info("\n" + response.toString());
        return response.getBody();

}

所以我的问题是,这意味着如何处理?
另外,我想问是否有方法可以确保使用getdeliveryreport方法的对象能够处理正结果和负结果(advancesDslrResponse.class或apiexception.class)

你可以抓住 RestClientResponseException 并使用 getResponseBodyAsString() 从例外中。然后你可以用jackson把它Map到一个物体上。
我就是这样处理的,也许还有别的办法。
关于最后一个问题,我想您需要在response对象中添加另一个字段,以便能够从异常传递json。另一种方法是使用另一个表达式重新抛出异常并稍后捕获,或者根本不重新抛出异常并稍后捕获。
