Description:
Parameter 1 of constructor in org.springframework.boot.autoconfigure.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/*");
}
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 clas
s 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

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);
spring boot是啥}
if (!StringUtils.isEmpty(sei)) {
try {
seiClass = ClassLoaderUtils.loadClass(sei, implementorClass);
} catch (ClassNotFoundException ex) {
throw new String("SEI_LOAD_FAILURE_MSG"), ex);
}
WebService seiAnnotation = Annotation(WebService.class);
if (null == seiAnnotation) {
throw new String("SEI_WITHOUT_WEBSERVICE_ANNOTATION_EXC"));
}
if (seiFromWsAnnotation
&& (!StringUtils.isEmpty(seiAnnotation.portName())
|| !StringUtils.isEmpty(seiAnnotation.serviceName())
|| !StringUtils.dpointInterface()))) {
String expString = String("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/*");
}
以上为个⼈经验，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
