Question

我正在开发Spring webservice（SpringWSTemplate），我试图覆盖org.springframework.ws.transport.http.HttpComponentsMessageSender 我有一个如下代码：

public class CustomHttpComponentsMessageSender extends
org.springframework.ws.transport.http.HttpComponentsMessageSender {
@Override
public WebServiceConnection createConnection(URI uri) throws IOException {

CookieStore cookieStore = new BasicCookieStore();
HttpComponentsConnection conn = (HttpComponentsConnection) super
.createConnection(uri);
HttpClientBuilder httpClientBuilder=HttpClientBuilder.create();
HttpClient httpclient = httpClientBuilder.setDefaultCookieStore(cookieStore).build();
HttpPost httpGet = new HttpPost(uri);
HttpResponse response = httpclient.execute(httpGet);
return conn;
}

}

当代码执行到达行：HttpClient httpclient = httpClientBuilder.setDefaultCookieStore(cookieStore).build();

时

我收到以下异常

我在构建路径中使用jar，并且在类路径中有jar条目。

<classpathentry kind="lib" path="lib/httpclient-4.3.3.jar"/>
<classpathentry kind="lib" path="lib/commons-logging-1.1.3.jar"/>
<classpathentry kind="lib" path="/sapadtreco/lib/httpmime-4.3.1.jar"/>
<classpathentry kind="lib" path="lib/spring-ws-core-2.1.4.RELEASE.jar"/>
<classpathentry kind="lib" path="lib/fluent-hc-4.3.jar"/>

非常感谢快速帮助。

可能是由于类路径中的httpclient-4.3.3.jar文件无效/损坏/丢失。尝试展开此文件并检查其是否有效并在其中包含ManagedHttpClientConnectionFactory类。

java.lang.NoClassDefFoundError： - 不能初始化类org.apache.http.impl.conn.ManagedHttpClientConnectionFactory
