Apache CXF客户端在Eclipse中加载良好，但独立的jar在WSDLServiceFactory中引发NullpointerException

Question

我的目标是使用mvn程序集创建一个在具有所有依赖项的独立jar中运行的Web Service客户端：

我使用CXF代码生成器wsdl2java生成了客户端，并创建了一个名为NetBanxAutostatementService的@WebServiceClient。

对于依赖我

<cxf.version>2.5.2</cxf.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>${cxf.version}</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-http</artifactId>
        <version>${cxf.version}</version>
        <scope>runtime</scope>
    </dependency>

拼命地我什至试图添加更多的“东西”

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-core</artifactId>
        <version>2.5.2</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf</artifactId>
        <version>2.5.2</version>
        <type>pom</type>
        <scope>runtime</scope>
    </dependency>

问题：每次我尝试运行“ java -jar target / Netbanx-0.0.1-SNAPSHOT-jar-with-
dependencies.jar”

INFO [main] (Netbanx.java:97) - autostatement_wsdlLocation:https://www.test.netbanx.com/cgi-bin/autostatement_wsdl
Exception in thread "main" java.lang.NullPointerException
at org.apache.cxf.wsdl11.WSDLServiceFactory.<init>(WSDLServiceFactory.java:92)
at org.apache.cxf.jaxws.ServiceImpl.initializePorts(ServiceImpl.java:204)
at org.apache.cxf.jaxws.ServiceImpl.<init>(ServiceImpl.java:148)
at org.apache.cxf.jaxws.spi.ProviderImpl.createServiceDelegate(ProviderImpl.java:91)
at javax.xml.ws.Service.<init>(Service.java:56)
at com.netbanx.autostatement.NetBanxAutostatementService.<init>  (NetBanxAutostatementService.java:39)
at my.project.netbanx.Netbanx.<init>(Netbanx.java:98)
at my.project.netbanx.Netbanx.main(Netbanx.java:130)

这在调用WebServiceClient autostatementService = new
NetBanxAutostatementService（autostatement_wsdlLocation）的行中发生；我通过日志行知道我没有将autostatement_wsdlLocation传递为null

Java代码：

URL autostatement_wsdlLocation = null;
URL payment_wsdlLocation = null;
try {
    autostatement_wsdlLocation = new URL(properties.getProperty("autostatement_wsdlLocation"));
    payment_wsdlLocation = new URL(properties.getProperty("payment_wsdlLocation"));
} catch (MalformedURLException e) {
    logger.error("MalformedURLException",e);
}

    /**
     * Load the Netbanx's webservices AutostatementService and PaymentService
     */
try {           
    logger.info("autostatement_wsdlLocation:"+autostatement_wsdlLocation.toString());
    autostatementService = new NetBanxAutostatementService(autostatement_wsdlLocation); //it is here I get the NullPointerException error
    logger.info("payment_wsdlLocation:"+payment_wsdlLocation.toString());
    paymentService = new NetBanxPaymentService(payment_wsdlLocation);
webServiceStarted = true;
    } catch(javax.xml.ws.WebServiceException wsException ){
        String error = "Cannot create NetBanx web service please make sure this host can reach:" + autostatement_wsdlLocation +" and " + payment_wsdlLocation;
        logger.error(error);
        logger.error("WebServiceException",wsException);

}

很可能是您创建单个jar的方式。程序集插件的常规用法不允许这样做，因为CXF的META-INF / 的各个部分需要合并在一起。那将包括所有/ META-
INF / html" target="_blank">spring
以及/ META-INF / cxf /
*中的许多内容，我建议为此使用shade插件。有关示例，请参阅CXF捆绑包的pom.xml。
