NoClassDefFoundError org/apache/cxf/jaxrs/client/WebClient

Question

我是 CXF 网络服务的新手。我需要写一个休息客户端。我得到

 java.lang.NoClassDefFoundError: org/apache/cxf/jaxrs/client/WebClient
 com.test.ws.CXFWebServiceConnector.get(CXFWebServiceConnector.java:21)
 com.test.ws.SimpleServlet.doGet(SimpleServlet.java:29)
 javax.servlet.http.HttpServlet.service(HttpServlet.java:620)
 javax.servlet.http.HttpServlet.service(HttpServlet.java:727)
 root cause

 java.lang.ClassNotFoundException: org.apache.cxf.jaxrs.client.WebClient
 org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1720)
 org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1571)

javax.servlet.http.HttpServlet.service(HttpServlet.java:727)

这不是 Maven 项目。下面的罐子被添加到我的 class 路径中。要获得 NoClassDefinition 异常，我是否缺少任何其他库？

这是我访问 Restful 网络服务的方式

public String get(String url) {
    String response = null;
    WebClient client = WebClient.create(url);
    client.accept(MediaType.APPLICATION_JSON);
    HTTPConduit conduit = WebClient.getConfig(client).getHttpConduit();
    HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
    httpClientPolicy.setAllowChunking(false);
    conduit.setClient(httpClientPolicy);
    TLSClientParameters clientParameters = new TLSClientParameters();
    clientParameters.setDisableCNCheck(true);
    clientParameters.setSecureSocketProtocol("TLS");
    conduit.setTlsClientParameters(clientParameters);
    try {
        response = client.get(String.class);

    } finally {
        if (client != null) {
            client.reset();
        }
    }

    return response;
}

Answer 1

WebClient 是 cxf-rt-frontend-jaxrs.jar 的一部分。我猜你没有 cxf JAXRS 相关的罐子。

Answer 2

在项目根目录中使用以下命令来检测需要哪些依赖项：

mvn dependency:tree -Dincludes=org.apache.cxf
