解决SpringBoot集成Apache CXF 发布服务端后,客户端调用不了的问题


先说解决方法：

? 在META-INF中创建services文件夹， 以Provider这个类的全名来新建立一个文件，文件中的内容为指定实现类的全名，如下：

问题背景:

? 项目涉及到周边老系统的数据交互，采用webService的方式。调用webService有很多方式，我采用了最偷懒的方式--idea生成客户端代码(就此埋下了坑)。

? 后来需求增加功能，需要发布一个WebService服务接收周边系统下发的数据。(周边系统老的一批)。因为是SpringBoot项目，并且SpringBoot对Apache CXF也有很好的支持，所以我选择了cxf。架构大概如下：

项目架构:

启动正常访问，完美（才怪）

服务端访问是没有问题，可是突然发现自己原来的客户端都访问不了了：

看了下异常，应该是创建服务代理时出了问题。

客户端代码也没有改动，怎么多了个服务端就访问不了了呢？

把服务端的代码删掉后重试，还是异常。感觉祸闯大了。。。

经过我不严谨的科学对照试验发现：只要引了ApacheCXF依赖就会报错，所以觉得是jar包冲突。Maven查找一下并没有发现明显的冲突。于是跟一下代码

发现：

image-20200430103405528.png

image-20200430103009917.png

查找一些资料发现，原来

每个 Service 对象都有自己的代理，这些代理是使用 javax.xml.ws.Provider#createServiceDelegate 方法创建的。Service 对象将其所有实例方法都委托给它的代理。

原来是创建服务代理（ServiceDelegate）的时候，由于引了ApacheCXF的依赖，导致 javax.xml.ws.Provider 有两个实现类。并且程序默认选择了org.apache.cxf.jaxws.spi.ProviderImpl作为createServiceDelegate 方法的提供者。（还是冲突）


image-20200429161723171.png

那么怎么指定我们想要的实现呢？就是文章开头说的


在META-INF中创建services文件夹， 以Provider这个类的全名来新建立一个文件，文件中的内容为指定实现类的全名，如下：

具体为什么只要如上配置就可以指定实现呢？
