引起：java.lang.VerifyError：无法链接com/fasterxml/jackson/databind/type/ReferenceType：无法从最终类继承

Question

我使用的是 Spring 版本 4.3.13.RELEASE、Spark 版本 2.2.0-2.11、mongo-spark-connector_2.11(2.2.0)、jackson 2.8.9。我的应用程序在 Tomcat7 中运行良好，但在 Wildfly10 中出现异常

org.springframework.web.util.NestedServletException：处理程序调度失败；嵌套异常是 java.lang.VerifyError: Failed to link com/fasterxml/jackson/databind/type/ReferenceType (Module "deployment.app.war:main" from Service Module Loader): 无法从 org.springframework 的最终类继承。 web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:982) 在 org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:901) 在 org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java: 970) 在 org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:872) 在 javax.servlet.http.HttpServlet.service(HttpServlet.java:707) 在 org.springframework.web.servlet.FrameworkServlet.service (FrameworkServlet.java:846) 在 javax.servlet.http。

Answer 1

由 maven 或 gradle war 插件创建的 spring boot 2.0 war 将适用于 jboss EAP 7.1。同样的 war 文件将通过 jboss EAP 7.0 服务器上的异常。

The exception is java.lang.VerifyError: Failed to link com/fasterxml/jackson/databind/type/ReferenceType

出现部署异常是因为 jboss 有自己的 jackson 库，并且发生类加载时间验证错误。

SOLUTION : 这个问题的解决方案是在WEB-INF文件夹中添加一个名为jboss-deployment-structure.xml的特定于jboss的xml文件。

<?xml version='1.0' encoding='UTF-8'?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
<deployment>
<exclusions>
<module name="com.fasterxml.jackson.core.jackson-annotations" />
<module name="com.fasterxml.jackson.core.jackson-core" />
<module name="com.fasterxml.jackson.core.jackson-databind" />
<module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
<module name="org.jboss.resteasy.resteasy-jackson2-provider" />
<module name="org.slf4j" />
</exclusions>
</deployment>
</jboss-deployment-structure>

我在 EAP 6.4 中运行应用程序时遇到相同的错误，如下所示， 我已迁移到 EAP 7.1.0，错误得到解决，应用程序运行良好。这是因为 jboss EAP6 中的 jakson jar 版本较旧，请参阅https://issues.jboss.org/browse/JBEAP-5189现在已在 7.x 版本中解决
