Could not initialize class org.apache.http.client.fluent.Executor

Question

SSM中使用网易易盾短信验证码服务时，遇到异常NoClassDefFoundError: Could not initialize class org.apache.http.client.fluent.Executor

控制器代码：

@PostMapping("/sendCode")
    public ReturnMsg sendCode(@RequestParam("phone") String phone) {
        //发送短信验证码
        SendResponse sendResponse = SendSMSUtils.sendOtp(phone);
        //将requestId存储保存到全局变量
        requestId = sendResponse.getData().getRequestId();
        return ReturnMsg.success("验证码发送成功");
    }

发送验证码的方法，使用的易盾提供的示例代码

public static SendResponse sendOtp(String phone) {
        // 这是你的 国内验证码短信 业务的 ID。可以登录易盾官网查看此业务 ID。
        String businessId = "7736a8f77362442d87527b32cffd2672";
        // 这是你事先创建好的模板，且已通过审核。
        String templateId = "16309";

        // 此处假设目标模板内容里只有验证码一个变量，所以没有其它变量需要指定
        Map<String, String> variables = Collections.emptyMap();

        // 发国内短信时，不指定 Country Calling Code
        Map<String, String> param = createSendParam(businessId, templateId, variables, phone);

        return RequestUtils.postForEntity(URI_SEND_SMS, param, SendResponse.class);
    }

发送post请求

public static <R> R postForEntity(String uri, Map<String, String> params, Class<R> responseType) {
        try {
            String strResponse = Request.Post(uri)
                    .bodyForm(convertToFormData(params), StandardCharsets.UTF_8)
                    .execute()
                    .returnContent()
                    .asString();

            return parseResponse(strResponse, responseType);
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
    }

执行execute()方法时抛出异常，NoClassDefFoundError: Could not initialize class org.apache.http.client.fluent.Executor

public Response execute() throws ClientProtocolException, IOException {
        return new Response(this.internalExecute(Executor.CLIENT, (HttpContext)null));
    }

Executor类

public class Executor {
static final PoolingHttpClientConnectionManager CONNMGR;
    static final HttpClient CLIENT;
//...
static {
        SSLConnectionSocketFactory ssl = null;

        try {
            ssl = SSLConnectionSocketFactory.getSystemSocketFactory();
        } catch (SSLInitializationException var7) {
            try {
                SSLContext sslcontext = SSLContext.getInstance("TLS");
                sslcontext.init((KeyManager[])null, (TrustManager[])null, (SecureRandom)null);
                ssl = new SSLConnectionSocketFactory(sslcontext);
            } catch (SecurityException var4) {
            } catch (KeyManagementException var5) {
            } catch (NoSuchAlgorithmException var6) {
            }
        }

        Registry<ConnectionSocketFactory> sfr = RegistryBuilder.create().register("http", PlainConnectionSocketFactory.getSocketFactory()).register("https", ssl != null ? ssl : SSLConnectionSocketFactory.getSocketFactory()).build();
        CONNMGR = new PoolingHttpClientConnectionManager(sfr);
        CONNMGR.setDefaultMaxPerRoute(100);
        CONNMGR.setMaxTotal(200);
        CONNMGR.setValidateAfterInactivity(1000);
        CLIENT = HttpClientBuilder.create().setConnectionManager(CONNMGR).build();
    }

整个示例代码在一个单独的项目里跑没有问题，但在我的ssm项目里就会抛下面的异常，求指点

运行结果及报错内容

Failed to complete request: org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.apache.http.impl.conn.PoolingHttpClientConnectionManager.setValidateAfterInactivity(I)V

把导入的包名删除比如import xx.xx.xx，试着手动导入包名，看看那两个包存在冲突，进行修改即可。
