Java 在tomcat或weblogic上使用lucene和spring重新部署时发生LinkageError

我有一个服务，可以读取csv文件，并使用lucene回答来自该数据的查询。维修模块在单机和单元测试中都能完美工作。该服务使用spring创建所有lucene类（目录、分析器…请参见下面的ServiceConfig）

该服务由SpringRESTWeb应用程序使用。第一次在tomcat或weblogic中部署时，它工作正常。但当我尝试重新部署它时，它无法再次加载spring上下文，错误如下：

你知道为什么它只运行一次吗？有什么办法可以解决吗？

你的项目使用什么版本的

lucene

，

springbeans

和

java

吗？对不起，我在度假。。因此：lucene=4.10.1、spring=3.2.12.RELEASE和Java=jdk1.7.0\u 60在JBoss EAP 6.3.3、jdk1.7.0\u 21和lucene 4.10.3上也会发生同样的事情。至少我们可以排除春天。看起来Lucene根本无法进行热部署。我对它做了一些深入的研究，现在我很确定它不会工作，因为Lucene试图尽我所能控制它自己的类加载和线程管理。这将与任何其他标准类加载器不兼容，可能与自定义类加载器不兼容。
