java - JBOSS 7 - Spring ContextLoaderListener ClassNotFoundException

Question

我正在尝试将我的 JBOSS 5.1 应用程序迁移到 JBOSS 7.0.2。在管理控制台中，我选择部署 -> 添加内容和我的 .war 并尝试启用它。我已经解决了一些问题，但无法弄清楚这个:(总之，最后很长)

Caused by: java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener from [Module "deployment.ZaprogsProject.war:main" from Servic
e Module Loader]

我将以下文件复制到 JBOSS7\standalone\lib\:

spring-aop-3.0.5.RELEASE.jar
spring-asm-3.0.5.RELEASE.jar
spring-beans-3.0.5.RELEASE.jar
spring-context-3.0.5.RELEASE.jar
spring-context-support-3.0.5.RELEASE.jar
spring-core-3.0.5.RELEASE.jar
spring-expression-3.0.5.RELEASE.jar
spring-jdbc-3.0.5.RELEASE.jar
spring-orm-3.0.5.RELEASE.jar
spring-test-3.0.5.RELEASE.jar
spring-tx-3.0.5.RELEASE.jar
spring-web-3.0.5.RELEASE.jar
spring-webmvc-3.0.5.RELEASE.jar

我读过这个:https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application+from+AS5+or+AS6+to+AS7 (调试并解决 ClassNotFoundExceptions 和 NoClassDefFoundErrors) 但无法为我找到解决方案，并且仍然遇到相同的错误。有人可以帮忙吗？

JBoss AS 7 以不同的方式进行类加载。

WAR 中的所有类都使用相同的类加载器加载。这意味着打包在 WEB-INF/lib 中的类与 WEB-INF/classes 中的类被视为相同。因此它适合你。

但是正如您所说，您的 WEB-INF/lib 已经臃肿。这不是正确的方法。

您需要制作一个模块:转到模块文件夹，使用主文件夹创建文件夹结构，并将包含条目的 jar 和 module.xml 放入其中。像这样的东西:

<main-class name="org.jboss.msc.Version"/>

<resources>
    <resource-root path="jboss-msc-1.0.1.GA.jar"/>
</resources>

<dependencies>
    <module name="javax.api"/>
    <module name="org.jboss.logging"/>
    <module name="org.jboss.modules"/>

    <!-- Optional deps -->
    <module name="javax.inject.api" optional="true"/>
    <module name="org.jboss.threads" optional="true"/>
    <module name="org.jboss.vfs" optional="true"/>
</dependencies>

您还需要更新 MANIFEST。详细信息在这里: https://docs.jboss.org/author/display/MODULES/Module+descriptors
