Question

我有一个Web应用程序，我使用resteasy和spring。它成功部署使用WAR时，但在部署EAR时失败。

这是父pom.xml： `

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

这是WAR pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <build>

</project>

这是EAR pom.xml：

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

当我将EAR部署到jboss时，我收到以下错误：

Answer 1

可能你的问题与weblogic类加载的不同策略有关。您可以尝试通过配置weblogic.xml来强制优先选择web-inf中的jar。看看here。您还可以指定类加载顺序。此外，为了更好地理解app-server中的类别编码与标准java类加载机制的不同，我建议你阅读this answer和this link。

Answer 2

我写了一个问题的解决方案，在这里： ClassNotFoundException for included dependency

我相信它可以帮到你。

Jboss WAR成功部署，但EAR未能通过classNotFoundException
