创建CXF Web服务客户端时发生ServiceConstructionException（scala + java + wsdl2java） [英] ServiceConstructionException when creating a CXF web service client (scala+java+wsdl2java)

问题描述

这些其他问题暗示了一个解决方案，但我一直无法得到这个工作：

无法解析http://schemas.xmlsoap.org/wsdl/soap/ 的绑定

创建CXF Web服务客户端时的ServiceConstructionException < br>

当我通过执行 java -Xdebug -jar myapp.jar m得到一个 ServiceConstructionException：当应用程序进行SOAP调用时，无法解析null 的绑定。当我在IntelliJ中启动应用程序时，应用程序和SOAP调用工作得很好。以下是重现错误的最简单示例： https://github.com/stianlagstad / mainclass-and-jxf-problems-demo

重现步骤：

- gradle clean build &安培;&安培; java -Xdebug -jar build / libs / mainclass-and-jxf-problems-demo.jar

- 转到 http：// localhost：4242 / endpoint / 并查看错误

任何人都可以帮我弄清楚哪个我必须做些改变才能使SOAP调用起作用？

编辑以提供更多信息：

如果我编辑 build.gradle 不排除META-INF（即具有 configurations.compile.collect {it.isDirectory（）？it：zipTree（it） } 代替 configurations.compile.collect {it.isDirectory（）？it：zipTree（it）.matching {exclude {it.path.contains（'META-INF' ）}}} ）我得到这个错误：错误：无法找到或加载主类com.shadowjarcxfproblem.JettyLauncher 作为一个罐子）。在IntelliJ中启动应用程序仍然有效，然后SOAP调用也可以工作。

解决方案

并尝试了一堆不同的东西，我终于偶然发现了一些有用的东西！

在此任务中使用gradle shadowjar插件可解决此问题：

  import com.github.jengelman .gradle.plugins.shadow.transformers.ServiceFileTransformer 
 shadowJar {
 //确保正确处理cxf服务文件，以便SOAP服务正常工作。 
 //价https://stackoverflow.com/questions/45005287/serviceconstructionexception-when-creating-a-cxf-web-service-client-scalajava 
变换（ServiceFileTransformer）{
路径='META-INF / cxf'
包含'bus-extensions.txt'
} 
} 
  

These other questions hint at a solution but I haven't been able to get this to work:
Could not resolve a binding for http://schemas.xmlsoap.org/wsdl/soap/
ServiceConstructionException when creating a CXF web service client
How to package an Apache CXF application into a monolithic JAR with the Maven "shade" plugin

When I start my application by doing java -Xdebug -jar myapp.jar I'm getting a ServiceConstructionException: Could not resolve a binding for null when the app makes a SOAP call. The app and the SOAP call works just fine when I start the application in IntelliJ. Here is a minimal example reproducing the error: https://github.com/stianlagstad/mainclass-and-jxf-problems-demo

Steps to reproduce:
- gradle clean build && java -Xdebug -jar build/libs/mainclass-and-jxf-problems-demo.jar
- Go to http://localhost:4242/endpoint/ and see the error

Can anyone help me figure out which changes I have to do to make the SOAP call work?

Edit to provide more information:

If I edit build.gradle to not exclude META-INF (i.e. having configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } instead of configurations.compile.collect { it.isDirectory() ? it : zipTree(it).matching{exclude{it.path.contains('META-INF')}} }) I get this error instead: Error: Could not find or load main class com.shadowjarcxfproblem.JettyLauncher (when starting the app as a jar). Starting the app in IntelliJ still works however, and the SOAP call works then as well.

The stacktrace for the cxf error:

解决方案

After reading these two and trying a bunch of different things I finally stumbled upon something that works!
How to package an Apache CXF application into a monolithic JAR with the Maven "shade" plugin
https://discuss.gradle.org/t/how-do-i-use-the-gradle-shadow-plugin-to-merge-spring-handlers-and-spring-schemas-files-of-multiple-spring-jar-dependencies/6713/6

Using the gradle shadowjar plugin with this task solved the problem:

import com.github.jengelman.gradle.plugins.shadow.transformers.ServiceFileTransformer
shadowJar {
    // Make sure the cxf service files are handled correctly so that the SOAP services work.
    // Ref https://stackoverflow.com/questions/45005287/serviceconstructionexception-when-creating-a-cxf-web-service-client-scalajava
    transform(ServiceFileTransformer) {
        path = 'META-INF/cxf'
        include 'bus-extensions.txt'
    }
}
