WebLogic 12c中的Guava 15.0 jar冲突

Question

我在一个在WebLogic 12c上部署的应用程序中从guava 14.0.1更新到15.0,并且在部署期间我得到了一个我无法解决的java.lang.NoSuchMethodException:

我已经被使用WebLogic喜欢的应用,包过滤的类加载器在我的weblogic.xml文件中所描述这里,为了解决在WebLogic中12C运行时发生冲突,因为它似乎重新打包库的旧版本.这一直在番石榴14.0.1中工作,但在15.0中没有.

据我所知,更喜欢com.google.common.*包应该包含所有内容.这个Finalizer类是否在类加载器过滤发生之前做了一些特殊的事情,从而尝试加载看似具有不同API的旧版本？

是否有替代解决方案使用与应用程序打包的guava-15.0.jar而不是与服务器捆绑的内容？

Answer 1

有一个未解决这个问题的公开问题#1527(Guava 15无法部署到任何JEE6容器),在修复此问题后发生了这个问题.请注明和/或评论并等待修复(评论#33表明版本15.0.1可能会在近期发布).

编辑: 同时,新的maven版本解决了这个问题:

关于JEE6/CDI 1.0的说明

在Guava 15.0中添加了一个解决方法,使其与CDI 1.1(在JEE7容器中使用)兼容,导致带有CDI 1.0的Guava(在JEE6容器中使用)出现问题.

如果你在CDI 1.0环境中使用Guava,你应该使用guava-15.0-cdi1.0.jar而不是普通的Guava jar.在Maven中,依赖关系可以指定为:

<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>15.0</version>
  <classifier>cdi1.0</classifier>
</dependency>

如果要在JEE 6和7服务器上部署,则必须使用Guava 13或等到16发布.
