Question

当我将ear项目部署到weblogic时，在应用程序启动期间，LinkageError显示如下：

weblogic的版本为10.3.6.0

Answer 1

这种冲突可能是因为你的某个应用程序在一个jar中有一个类（org / springframework / core / io / ResourceLoader），这个类与weblogic的嵌入jar（http://www.findjar.com/class/org/springframework/core/io/ResourceLoader.html）和类之一有冲突。同名。

Answer 2

此问题是由于 JVM 永久代（Perm Gen）中的空间不足。

在 setDomainEnv.sh 中的管理服务器的java选项中增加 Perm Gen 空间。

可以使用

根据要求调整大小

-XX：MaxPermSize 和 -XX：PermSize

JVM 选项。

需要设置以下内容：

USER_MEM_ARGS=-Xms2048m -Xms2048m -XX:PermSize=512 -XX:MaxPermSize=1024

然后，尝试重新启动管理服务器。

如果这些参数没有问题，那么

可以编辑

node.properties 文件来更改这些参数：

- SecureListener = false(by default is true)
- StartScriptEnabled = true 
- StopScriptEnabled = true
