spring webservice Invalid NamespaceHandler 问题（jaxws）

Question

我正在使用 Spring 构建 Web 服务。我可以构建项目并将其部署到 tomcat，但是当服务器启动时出现以下错误：

无效的命名空间处理程序类 [org.apache.cxf.jaxws.spring.NamespaceHandler] 对于命名空间 [http://cxf.apache.org/jaxws]：问题 带有处理程序类文件或依赖 班级;嵌套异常是 java.lang.NoClassDefFoundError： org/springframework/beans/factory/xml/NamespaceHandlerSupport

我已经在我的类路径中包含了 cxf-rt-frontend-jaxws.jar。

我的 bean 定义在这里：

 <jaxws:endpoint id="helloWebservice"
  implementor="#com.xxx.impl.HelloWebserviceImpl"
  address="/hellows">
 </jaxws:endpoint>

我的 lib 文件夹包含（WEB-INF/lib）：

Answer 1

您似乎缺少一个弹簧罐，或者您有一个旧版本的弹簧罐。尝试在类路径上获取最新的spring-beans.jar。还要确保在较旧的类路径上没有另一个这样的 jar。

Answer 2

所以，我也偶然发现了这个错误，这真的让我很紧张。所以，不用多说

环境：

Wildfly 20.0.1.Final

Java 11

目标：

我只想添加 cxf，以便我可以在 applicationContext.xml 中使用 cxf - spring 描述符（特别是 jaxws:endpoint），即

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    <!-- one or more jaxws:endpoint POJO declarations -->
    <jaxws:endpoint id="POJOEndpoint" address="/test" implementor="com.test.myRandomPojoEndpoint">
        <jaxws:invoker>
            <bean class="org.jboss.wsf.stack.cxf.InvokerJSE"/>
        </jaxws:invoker>
    </jaxws:endpoint>
</beans>

问题：

但我得到的只是

无效的命名空间处理程序类 [org.apache.cxf.jaxws.spring.NamespaceHandler] 用于命名空间 [http://cxf.apache.org/jaxws]：处理程序类文件或问题 依赖类；嵌套异常是 java.lang.NoClassDefFoundError： org/springframework/beans/factory/xml/NamespaceHandlerSupport

解决方案：

在开始之前，您应该知道要使这些东西工作，您必须安装 SPRING LIBRARIES 到您的 wildfly 应用程序服务器等等...

我的wildfly环境中的spring库列表：

spring-aop-5.2.9.RELEASE.jar
spring-beans-5.2.9.RELEASE.jar
spring-context-5.2.9.RELEASE.jar
spring-core-5.2.9.RELEASE.jar
spring-expression-5.2.9.RELEASE.jar
spring-jcl-5.2.9.RELEASE.jar
spring-tx-5.2.9.RELEASE.jar
spring-web-5.2.9.RELEASE.jar

安装路径如下

wildfly-20.0.1.Final\modules\system\layers\base\org\springframework\spring\main

只需将spring库放在此路径中并添加module.txt（与spring库相同的文件夹）如下

模块.txt

注意事项：

那么，如果这很简单，为什么我会失败？为什么？

一开始我在里面安装了spring库

wildfly-20.0.1.Final\modules\system\layers\base\org\spring\main

这会造成很多痛苦，因为

如果你看过 wildfly-20.0.1.Final\modules\system\layers\base\org\apache\cxf\impl\main\module.xml，你会看到它对spring有依赖，即

    <module name="org.springframework.spring" optional="true">
        <imports>
            <include path="META-INF"/>
        </imports>
    </module>

但是，我以 org.spring 而不是 org.springframework.spring 的不同名称安装了 spring 库，所以这是我失败的根源。

我的 jboss-deployment-structure.xml（在 WEB-INF 文件夹中）是

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.springframework.spring">
                <imports>
                    <include path="META-INF"/>
                </imports>
                <exports>
                    <include path="META-INF"/>
                </exports>
            </module>
            <module name="org.apache.cxf">
                <imports>
                    <include path="META-INF/cxf"/>
                    <include path="META-INF"/>
                </imports>
                <exports>
                    <include path="META-INF/cxf"/>
                    <include path="META-INF"/>
                </exports>
            </module>
            <module name="org.apache.cxf.impl">
                <imports>
                    <include path="META-INF/cxf"/>
                    <include path="META-INF"/>
                </imports>
                <exports>
                    <include path="META-INF/cxf"/>
                    <include path="META-INF"/>
                </exports>
            </module>
        </dependencies>
    </deployment>
