java - WSO2 Web服务空指针异常

Question

我正在使用下面给出的命令为 WSO2 Web 服务生成 wso2 客户端

wsimport -keep -verbose https://svn.wso2.org/repos/wso2/people/asela/user-mgt/jaxws/RemoteUserStoreManagerService.wsdl

我使用 JAVA 1.8.0_112 生成了此客户端。当我尝试使用生成的方法构造函数(URL url)指定 WSDL LOCATION 来调用客户端时，出现以下异常:

Exception in thread "main" java.lang.NullPointerException

我正在使用 wso2 身份服务器 - 5.2.0 版本。 IT 也在 JAVA 1.8.0_112 上运行。我调用客户端的代码是 -

package org.wso2.carbon.test;

import java.net.MalformedURLException;
import java.net.URL;

import org.wso2.carbon.um.ws.service.RemoteUserStoreManagerService;
import org.wso2.carbon.um.ws.service.RemoteUserStoreManagerServicePortType;
import org.wso2.carbon.um.ws.service.RemoteUserStoreManagerServiceUserStoreException_Exception;

public class TestUserLogin {
    public static void main(String args[]) throws MalformedURLException, RemoteUserStoreManagerServiceUserStoreException_Exception {
        RemoteUserStoreManagerService rus = 
                new RemoteUserStoreManagerService(new URL("https://ril15066yjb152:9443/services/RemoteUserStoreManagerService?wsdl"));

        RemoteUserStoreManagerServicePortType rusm = rus.getRemoteUserStoreManagerServiceHttpSoap11Endpoint();

        System.out.println(rusm.authenticate("admin", "admin"));
    }

} 

我的 RemoteUserStoreManagerService 类是 -

package org.wso2.carbon.um.ws.service;

import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.ws.Service;

Answer 1

尝试使用此代码删除 NPE:

    RemoteUserStoreManagerService rus =
            new RemoteUserStoreManagerService();

    RemoteUserStoreManagerServicePortType rusm = rus.getRemoteUserStoreManagerServiceHttpsSoap11Endpoint();
    ((BindingProvider) rusm).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpoint);
    org.apache.cxf.endpoint.Client client = ClientProxy
            .getClient(rusm);

    HTTPConduit http = (HTTPConduit) client.getConduit();
    http.getAuthorization().setUserName("admin");
    http.getAuthorization().setPassword("admin");

    System.out.println("User authenticate? " + rusm.authenticate("admin", "admin"));
    List<String> listUsers = rusm.listUsers("*", 100);
    for (String user : listUsers) {
        System.out.println("User: " + user);

    }

更新1:您还需要在服务部分中使用此端口更新 WSDL:

    <wsdl:port name="RemoteUserStoreManagerServiceHttpsSoap11Endpoint" binding="ns:RemoteUserStoreManagerServiceSoap11Binding">
        <soap:address location="https://localhost:9443/services/RemoteUserStoreManagerService.RemoteUserStoreManagerServiceHttpsSoap11Endpoint/"/>
    </wsdl:port>

更新2:在验证用户身份验证之前添加了http基本身份验证。检查上面的代码。

我的客户回复:

User authenticate? true
User: WSO2.ORG/admin
