2.2.8快照版本的cxf-codegen-plugin有什么特别之处？

Question

我继承了一个基于CXF的项目，具有以下(相关的)原始依赖项(在pom.xml中)：

<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>2.2.7</version>
</dependency>
<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-http</artifactId>
        <version>2.2.7</version>
</dependency>
<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-ws-security</artifactId>
        <version>2.2.7</version>
</dependency>

和

<plugin>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-codegen-plugin</artifactId>
        <version>2.2.8-SNAPSHOT</version>

我所说的“原始”是指我在几年前收到的用于构建精细的源代码快照，这些年来一直处于休眠状态，而现在，需要对代码进行一些修改，它将不再按原样构建。

试图构建它的主要问题是，2.2.8-SNAPSHOT版本的cxf-codegen-plugin是无处可寻的.Maven找不到它并导致构建失败。

因此，我将上面的内容替换为(注意，惟一的区别是2.2.8比2.2.8-快照)

<plugin>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-codegen-plugin</artifactId>
    <version>2.2.8</version>

构建现在已经成功，但在没有找到的2个符号上失败：

1. Password.set_value(String value) --来自包裹org.oasis_open.docs.wss._2004._01.oasis_200401_wss_wssecurity_secext_1_0。
2. SQLService.setENDPOINT(String sei)来自自己的包，基于javax.xml.ws.Service。

Password和SQLService类的两个源文件都是由ApacheCXF2.2.8按本项目最初作者的设计动态生成的。

因此，我很快检查了这个文件的新生成版本，发现：

1. Password.set_value(String value)似乎已经被Password.setValue(String value)取代了。
2. SQLService.setENDPOINT(String sei)已被完全消除，而是要求sei在构造函数：SQLService(URL wsdlLocation, QName serviceName)中传递。

因此，我修改了调用这些方法的源代码，以适应这个看起来很小的变化，项目现在已经成功构建了！

但是.在运行时失败，但有以下例外：

注意:即使我硬编码WSDL中的实际(www)服务器URL (即用https://test.rserver.com替换http://localhost:8080 )，也会得到显示http://localhost:8080作为目标的ConnectException错误。显然，没有执行某些CXF-替换或解析。这会不会是问题所在的线索？CXF的哪个组件负责从http://localhost:8080到真实URL的神奇转换？

堆栈跟踪提示的位置正确吗(即JaxWsClientProxy、frontend.ClientProxy或.)？

at org.apache.cxf.interceptor.MessageSenderInterceptor$MessageSenderEndingInterceptor.handleMessage(MessageSenderInterceptor.java:62)
at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:243)
at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:484)

at org.apache.cxf.frontend.ClientProxy.invokeSync(ClientProxy.java:73)
at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:124)

如果是的话，为什么会发生这种情况，我如何解决这个问题？

现在..。如果我是一个CXF和/或JAX专家，我可能已经找出了堆栈跟踪中误导性“连接拒绝”提示的根本原因。

但在这一点上，我几乎迷失了方向，因为我知道SEI确实存在，身份验证用户名/密码是正确的:旧的二进制文件(带有依赖项的JAR)对此服务运行良好。

因此，我正在寻找一个线索或一个专家的洞察力，他可能已经看到了这种类型的“拒绝连接”堆栈跟踪，并且知道它可能是由而不是 typical reasons触发的。例如，cxf-codegen-plugin 2.2.8快照被2.2.8替换后引入的某种类型的不匹配？

或有关如何解决此问题的其他提示？

我想你改做SQLService可能是个问题

SQLService.setENDPOINT(String sei)已经完全消除，而是要求在构造函数中传递sei : SQLService(URL wsdlLocation，QName serviceName)。

您在构造函数调用中添加了新的URL吗？sei之前是什么？如果您输入了一个URL，很可能是它的连接失败了。您应该能够使用no构造函数。

如果您想在运行时设置URL (我猜这就是setENDPOINT调用所做的)，则需要操作BindingProvider。请参阅此线程http://cxf.547215.n5.nabble.com/How-to-change-the-service-URL-at-runtime-td3242927.html
