WebLogic 12c中的Guava 15.0 jar冲突 [英] Guava 15.0 jar conflict in WebLogic 12c

问题描述

我在WebLogic 12c上部署的应用程序中从guava 14.0.1更新到了15.0，并且在部署过程中遇到了无法解决的java.lang.NoSuchMethodException:

I updated from guava 14.0.1 to 15.0 in an application that deploys on WebLogic 12c, and I get a java.lang.NoSuchMethodException during deployment that I've been unable to resolve:

我已经在我的weblogic.xml文件中使用过WebLogic首选应用程序包类加载器过滤，如

I already have been using the WebLogic prefer-application-packages classloader filtering in my weblogic.xml file as described here in order to resolve a runtime conflict in WebLogic 12c as it seems to repackage an older version of the library. This had been working in guava 14.0.1, but does not in 15.0.

据我所知，更喜欢com.google.common.*软件包应包含所有内容.该终结器类在做类加载器筛选之前是否做一些特殊的事情，从而尝试加载看似具有不同API的旧版本?

As far as I can tell, preferring the com.google.common.* package should include everything. Does this Finalizer class do something special that is happening before the classloader filtering happens, thereby trying to load the old version that appears to have a different API?

是否有替代解决方案，可以使用与应用程序打包在一起的guava-15.0.jar而不是与服务器捆绑在一起的东西?

Is there an alternative solution to use the guava-15.0.jar packaged with the application instead of what is bundled with the server?

推荐答案

有一个打开解决此问题(修复了评论#33 建议该版本15.0.1即将发布).

There's an open issue #1527 targeting this problem (Guava 15 cannot be deployed to any JEE6 container) which occured after fixing this one. Please star and / or comment and wait for the fix (comment #33 suggests that version 15.0.1 could be released in near furture).

同时，问题已解决: //code.google.com/p/guava-libraries/wiki/Release15#A_note_on_JEE6 _/_ CDI_1.0>新的Maven版本:

Meanwhile, the issue was resolved by new maven release:

关于JEE6/CDI 1.0的注释

在Guava 15.0中添加了一种变通方法，以使其与CDI 1.1兼容 (在JEE7容器中使用)对于使用CDI 1.0的番石榴(使用过)造成了问题 在JEE6容器中).

A note on JEE6 / CDI 1.0

A workaround added in Guava 15.0 to make it compatible with CDI 1.1 (used in JEE7 containers) caused problems for Guava with CDI 1.0 (used in JEE6 containers).

如果在CDI 1.0环境中使用Guava，则应使用 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:

If you're using Guava in a CDI 1.0 environment, you should use guava-15.0-cdi1.0.jar instead of the normal Guava jar. In Maven, the dependency can be specified as:

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

如果要同时在JEE 6和7服务器上进行部署，则必须使用Guava 13或

If you want to deploy on both JEE 6 and 7 servers, you must use Guava 13 or wait until 16 is released.
