Spring EJB - WEB - ELASTICSEARCH - JPA - CRUD - 业务方法链接错误

我遇到麻烦，我一直在开发我的项目。我开始开发一个基于spring框架的业余爱好项目，过了一段时间，项目的各个部分开始融合在一起。 主要有两个模块，一个是EJB模块，另一个是WEB模块。存储库和核心EJB bean存储在EJB模块中，它们是从WEB模块中使用的。 由于我以前使用过弹性搜索，我对数据的处理速度和效率印象非常深刻，所以我想我会把它整合到我的爱好项目中。

为了集成elasticsearch，我采取了适当的措施，并将所需的库添加到项目的pom文件中。乍一看，似乎一切都运作良好，但后来事实证明情况并非如此。我创建了弹性搜索的存储库测试它们，我很高兴，当我测试了其他早期完美工作的特性时，我受到了以下例外的欢迎：

  

11：41：25,213 ERROR [io.undertow.request]（默认任务-33）UT005023：   对/ axyz-web / test / test的异常处理请求：   org.springframework.web.util.NestedServletException：处理程序调度   失败;嵌套异常是java.lang.LinkageError：loader约束   违规：解析接口方法时“com.myproject.axyz.beans.stateless.user.UserManagementLocal.findUsers（Lorg / springframework / data / domain / Pageable;）Lorg / springframework / data / domain / Page;”   类加载器（org / jboss / modules / ModuleClassLoader的实例）   目前的班级，   com / myproject / axyz / spring / controllers / test / TestController，和   类加载器（org / jboss / modules / ModuleClassLoader的实例）   方法的定义类，   com / myproject / axyz / beans / stateless / user / UserManagementLocal，有   该类型的不同Class对象   org / springframework / data / domain /签名中使用的可分页

第一次，我以为我编译了war-ejb项目的spring-boot-data-elasticsearch的不同版本（因为我想在我的web项目中使用crud存储库进行弹性搜索），经过一些研究后我注意到了怀疑被证实。

首先，我从WEB项目中删除了依赖项，因为它依赖于EJB模块，并再次编译项目然后部署它。因此，spring-boot-data-elasticsearch被编译为EJB模块。

我收到的下一条消息如下：

  

11：54：08,407 ERROR [org.springframework.web.context.ContextLoader]   （ServerService线程池 - 382）上下文初始化失败：   org.springframework.beans.factory.BeanDefinitionStoreException：   从ServletContext资源解析XML文档时出现意外异常   [/WEBINF/applicationContext.xml];嵌套异常是   org.springframework.beans.FatalBeanException：Class   [org.springframework.data.elasticsearch.config.ElasticsearchNamespaceHandler]   用于命名空间   [http://www.springframework.org/schema/data/elasticsearch]没有   实现[org.springframework.beans.factory.xml.NamespaceHandler]   接口

好的，下一轮，我将spring-boot-data-elasticsearch编译到EAR模块中，并将范围设置为两个模块中库的提供。

像这样：

VERSION NUMBERS 

    <properties>
     <spring.boot.framework.version>1.5.5.RELEASE</spring.boot.framework.version>
     <spring.version>4.3.8.RELEASE</spring.version>
     <org.springframework.version>4.3.8.RELEASE</org.springframework.version>
</properties>

连接示例：

    <elasticsearch:repositories base-package="com.xxxxxxxxxxxxxxxxxxx.spring.elasticsearch.repositories"/>  

<elasticsearch:transport-client id="esClient" cluster-nodes="localhost:9300" />

<bean id="esConnection" class="com.xxxxxxxxxxxxxx.core.elasticsearch.ESConnection" init-method="init"  scope="session">
    <constructor-arg name="con" ref="container"></constructor-arg>
    <property name="client" ref="esClient"></property>
</bean>

<bean name="elasticsearchTemplate" class="org.springframework.data.elasticsearch.core.ElasticsearchTemplate">
    <constructor-arg name="client" ref="esClient"/>
</bean>

我还尝试排除spring-data-commons（因为Pageable和Page以及其他组件在该库中定义）并将其单独编译到WEB模块中，但效果是一样的，我想使用elasticsearch及其存储库分别在两个模块中。

总之，如果我没有将elasticsearch库编译到我的WEB模块中，它将永远无法解释XML或创建bean（我也试过了JAVA注释，尝试了更新的版本，情况是一样的） 所以我不知道如何解决这个问题，因为如果将库编译到WEB模块中会发生链接错误。

有谁知道如何解决这个问题？有可能吗？
