Question

我正在尝试在CQ中实现Apache CXF。我使用cxf-codegen-plugin从WSDL生成了代理类。现在我的CxfServiceImpl.java看起来如下 -

import net.webservicex.ConvertTemperatureSoap;
import net.webservicex.TemperatureUnit;
import org.apache.felix.scr.annotations.Activate;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Service;
import org.osgi.framework.BundleContext;
import org.osgi.service.component.ComponentContext;

@Component(label = "CXF Service", immediate = true, metatype = true)
@Service(CxfService.class)
public class CxfServiceImpl implements CxfService {
    private ConvertTemperatureSoap convertTemperatureSoap;
    @Override
    public double convertCelsiusToFahrenheit(double valueToConvert) {
        return convertTemperatureSoap.convertTemp(
        valueToConvert, 
        TemperatureUnit.DEGREE_CELSIUS, 
        TemperatureUnit.DEGREE_FAHRENHEIT);
    }
    @Activate
    protected final void activate(final ComponentContext context) {
        convertTemperatureSoap =
        JaxWsClientFactory.create(
        ConvertTemperatureSoap.class,
        "http://www.w3schools.com/webservices/tempconvert.asmx");    
    }    
}

JaxWsClientFactory.java看起来像 -

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.BusFactory;
public class JaxWsClientFactory {
    public static <T> T create(Class<T> clazz, String portUrl) {
        ClassLoader oldClassLoader = Thread.currentThread().getContextClassLoader();
        try {
            Thread.currentThread().setContextClassLoader(BusFactory.class.getClassLoader());
            JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
            factory.setServiceClass(clazz);
            factory.setAddress(portUrl);
            return (T) factory.create();
        } finally {
            Thread.currentThread().setContextClassLoader(oldClassLoader);
        }
    }
}

我能够创建OSGI包并在Felix控制台中上传。但是当我尝试激活bundle然后我得到如下错误并且bundle状态显示为Active。

Answer 1

就我而言，我需要在该项目中从Java 11回滚到Java 8。

我知道这不是一个长期解决方案，但这可能对某人有所帮助。

更通用的解决方案是使用：

    <dependency>
        <groupId>javax.xml.ws</groupId>
        <artifactId>jaxws-api</artifactId>
        <version>2.3.1</version>
    </dependency>

Answer 2

当CXF委托JDK进行代理生成时，会发生此错误。问题在于，对于代理必须实现的所有接口，您只能设置一个类加载器。通常，用户的类路径中没有BindpProvider。 SO cxf使用总线类路径，该路径首先在bundle类路径中查找，然后在cxf类路径中查找。

您使用哪种CXF版本？在较旧的CXF版本中，此错误有时会产生误导。不仅在找不到BindingProvider类时出现问题。当BindingProvider由cxf和用户包加载但来自不同的类加载器时也会发生这种情况。

避免此问题的最佳方法是导入javax.xml.ws。因此，您发现与cxf相同的界面的可能性最大。如果错误仍然发生，您可能有两个包导出包。

在任何情况下，您的bundle插件指令都不应该像您的问题那样复杂。这只会导致问题。试试吧。

<instructions>
  <Bundle-SymbolicName>com.adobe.cq.customer-bundle</Bundle-SymbolicName>
  <Include-Resource>{maven-resources}</Include-Resource>
  <Import-Package>
    javax.xml.ws,
    *
  </Import-Package>
</instructions>

为什么嵌入所有依赖项有什么特殊原因？当像这样使用时，CXF通常可以很好地工作。相反，您可以使用CXF DOSGi多捆发行版中的捆绑包将CXF安装到CQ中。

Answer 3

将javax/xml/ws/BindingProvider类添加到类路径

Answer 4

如果您使用 maven ，here可以快速链接到可能的工件

Answer 5

我先说检查你的MANIFEST.MF。它抱怨它缺少javax.xml.ws包，因此检查它是否在Import-Package头中。

如果不是：那就是你的问题，我想你需要将它添加到你的pom.xml中。

如果，那就更加微妙了。

Answer 6

如果您安装了JDK 1.6（Java SE 6），我建议您阅读文档Using JAX-WS 2.x / Metro 1.x/2.0 with Java SE 6

通过阅读附件，我解决了类似的问题。
