									Description:

									Parameter 1 of constructor in org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration required a bean of type 'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath' that could not be found.

									The following candidates were found but could not be injected:

									    - Bean method 'dispatcherServletRegistration' in 'DispatcherServletAutoConfiguration.DispatcherServletRegistrationConfiguration' not loaded because DispatcherServlet Registration found non dispatcher servlet dispatcherServlet

									Action:

									Consider revisiting the entries above or defining a bean of type 'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath' in your configuration.

使用的SpringBoot版本是2.1.8，使用了cxf-spring-boot-starter-jaxws的版本是3.2.6。

网上有的说是版本不匹配造成的，但是我这边发现不是版本不匹配造成的，而是我的cxf配置类里注册Servlet的bean的name是dispatcherServlet，造成错误的。因此注册的servlet的bean的名称不能是dispatcherServlet

				?

									@Bean(name = "cxfServlet")

									 public ServletRegistrationBean cxfServlet() {

									  return new ServletRegistrationBean(new CXFServlet(), "/webservice/*");

									 }

在https://mvnrepository.com/artifact/org.apache.cxf/cxf-spring-boot-starter-jaxws查找到jaxws的各种版本，进入之后可以看到对应的springboot版本

解决springboot整合cxf启动报错,原因是版本问题

Springboot 整合 CXF 出现的bug总结

在之前整合cxf进spingboot项目时，总是报错Error creating bean with name 'endpoint' defined in class path，经过打断点源码层层调试，最终发现springboot在整合cxf的时候一些特性，解决方法如下：

报错信息如下

				?

									org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'endpoint' defined in class path resource [net/chinanets/sj/config/CxfConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.xml.ws.Endpoint]: Factory method 'endpoint' threw exception; nested exception is javax.xml.ws.WebServiceException: javax.xml.ws.WebServiceException: Attributes portName, serviceName and endpointInterface are not allowed in the @WebService annotation of an SEI.

1.服务端接口和接口的实现类，两者其一必须在@WebService注解后加入serviceName,targetNamespace,endpointInterface说明,且不能同时都加！源码中代码如下：

2.代码：

				?

									String sei = getImplementorClassName();

									        boolean seiFromWsAnnotation = true;

									        if (StringUtils.isEmpty(sei)) {

									            seiFromWsAnnotation = false;

									            sei = getWSInterfaceName(implementorClass);                

									        }

									        if (!StringUtils.isEmpty(sei)) {

									            try {

									                seiClass = ClassLoaderUtils.loadClass(sei, implementorClass);

									            } catch (ClassNotFoundException ex) {

									                throw new WebServiceException(BUNDLE.getString("SEI_LOAD_FAILURE_MSG"), ex);

									            }

									            WebService seiAnnotation = seiClass.getAnnotation(WebService.class);

									            if (null == seiAnnotation) {

									                throw new WebServiceException(BUNDLE.getString("SEI_WITHOUT_WEBSERVICE_ANNOTATION_EXC"));

									            }

									            if (seiFromWsAnnotation 

									                && (!StringUtils.isEmpty(seiAnnotation.portName())

									                || !StringUtils.isEmpty(seiAnnotation.serviceName())

									                || !StringUtils.isEmpty(seiAnnotation.endpointInterface()))) {

									                String expString = BUNDLE.getString("ILLEGAL_ATTRIBUTE_IN_SEI_ANNOTATION_EXC");

									                throw new WebServiceException(expString);

									            }

其中seiAnnotation指的是实现类的serviceName,targetNamespace,endpointInterface，其为空，则不会抛此异常。

3.解决这个异常后，又抛出另一个异常，怀疑是jar包问题，cmd进入工作空间项目目录，使用 mvn dependency:tree 查看项目jar包结构，发现cxf自动带入XmlSchema解析包，但是项目中又有一个单独的XmlSchema解析包，导致冲突，删除单独的xml解析包，即可解决。

4.springboot 可直接在application.properties配置文件中配置接口访问的过滤路径。cxf.path=/soap 可以替换 CxfConfig 配置类中的

				?

									@Bean

									     public ServletRegistrationBean dispatcherServlet() {

									        return new ServletRegistrationBean(new CXFServlet(), "/soap/*");

									     }
