实例化一个cxf服务导致其他无关服务注入失败

Question

我正在为某些 Web 服务开发消费者服务。该应用程序已经在提供 Web 服务（作为服务器），但这是第一个消费者。

这一代没问题，但我遇到了一个奇怪的 - 对我来说！ - 我尝试从消费者的构造函数中实例化 javax.xml.ws.Service 的问题服务：所有提供者 web 服务实现者 bean 突然变成 "undefined"（如果我评论来自 cxf.xml 的第一个提供者，第二个也是 'undefined'）。

看起来我触发了一些意外的注入，可能发生得太快了......但我不明白为什么，也不知道如何解决它！欢迎任何想法！

    </cxf:bus>

someServiceImpl:

    public SomeServiceImpl() throws MalformedURLException {
        SomeConsumerService service= new SomeConsumerService (); // this is the line causing the problem
    }

网络服务 SomeConsumerService :

public class SomeConsumerService extends javax.xml.ws.Service{

    public final static URL WSDL_LOCATION;
    public final static QName SERVICE = new QName("urn:test.com:anywhere/webservice/T", "SomeService");
    static {
        URL url = null;
        try {
            url = new URL("http://some.wsdl");
        } catch (MalformedURLException e) {
            System.err.println("Ooops! ");
        }
        WSDL_LOCATION = url;
    }

    public SomeConsumerService () {
        super(WSDL_LOCATION, SERVICE);
    }
}

上下文：

<bean name="someService" class="com.my.services.impl.SomeServiceImpl">
</bean>

<bean name="someProviderWebServiceImplementor"  class="com.my.services.impl.SomeProviderWebServiceImplementorImpl">
</bean>

Answer 1

一位同事设法找出了问题所在：看起来 cxf servlet 会在存在时基于 cxf.xml（仅！）创建自己的上下文。如果不是，它将在 application Context 中查找其配置。

尽管如此，它也只有在我创建消费者时才是正确的...因此，我不确定它是否更像是一个意想不到的副作用，还是一个真实的特性。

无论如何，这里有效的解决方案是：

将 cxf.xml 重命名为 another_name_for_cxf.xml
从应用程序导入重命名的文件-context.xml（或您给它的任何名称）
```
<import resource="classpath:another_name_for_cxf.xml"/>
```

然后，魔法就开始运转了！
