Javassist增强功能在部署上失败 [英] Javassist Enhancement Fails on Deployment

问题描述

我遇到在这个问题。主要错误消息：

错误pojo.BasicLazyInitializer - Javassist增强失败

我不知道它已经发生的频率，因为部署仍然成功。我试图解决上述问题时偶然发现了这个错误。我正在尝试部署到glassfish应用服务器（测试环境）。

基本上，我的应用程序在我的本地环境中工作正常，也使用 test run-war （请参阅我的上一个问题进一步的细节）。我打开了一个新问题，因为我觉得这可能会导致应用程序服务器上的许多问题的根源，因为增强在每次部署时都会失败。

已经有一个 JIRA ，但解决方法与webflow插件相关，该插件甚至不是用在我的项目中。我知道必须存在与javassist相关的依赖性问题，但我无法在JIRA或互联网上的其他地方找到任何有用的信息， other 插件也可能具有javassist依赖性。在我的Grails依赖项中，我只能看到一个javassist jar。

本地环境：

• Java 1.6.0_45


• Grails Tomcat插件7.0.5.3（适用于run-war）
  
  $ b

  应用服务器：
  
  

  
  
  • Glassfish 3.0.1 build 22
  
  
  • Java 1.6.0_07

  解决方案

  暗示，这是Glassfish应用服务器的问题。我不知道是什么原因导致这个bug，但这绝对不是预期的行为。
  
  

  我能够在本地Glassfish 3.0.1环境中重现相同的部署例外情况。幸运的是，在当地的Glassfish 3.1.2.2环境中，一切工作都很好。
  
  

  Grails 1.3.7在Glassfish 3.0.1上运行良好;但是，在升级到Grails 2.4.x（第一个2.4.0，然后是2.4.1，然后是2.4.2）之后，这个异常在部署时被抛出。我不知道是否确实是导致这种情况发生的Grails更新 - 尤其是因为我在项目中做了很多其他更改，例如，到域模型，新的hibernate版本 - ，但如果遇到与grails 2.4.x和Glassfish部署类似的问题，请提供版本3.1.2。一枪。
  
  

  如果我找到一些时间，我会尝试创建一个简单可重复的示例并发布JIRA问题。如果您阅读本文并感觉对此问题感兴趣，请自由创建JIRA;）。
  

  我已经回答我的另一个问题，与部署例外直接相关。
  

  I am encountering an error specified in the stacktrace at the bottom of this question. Main error message:

  ERROR pojo.BasicLazyInitializer - Javassist Enhancement failed

  I do not know how often it has occurred already, because the deployment still succeeded. I just stumbled upon this error when trying to fix the issue linked above. I am trying to deploy to a glassfish app server (test environment).

  Basically, my app works fine in my local environment, also with test run-war (see my previous question for further detail). I opened a new question because i feel like this could lead to the root of many problems on the app server, since the enhancement fails on every deployment.

  There is already a JIRA on that one, but the workaround relates to the webflow plugin, which is not even used in my project. I know there must be a dependency issue related to javassist, but I fail to find any useful information in the JIRA or elsewhere on the internet what other plugins might have a javassist dependency as well. In my Grails Dependencies, I can only see one javassist jar.

  Local Environment:

  • Java 1.6.0_45
  • Grails Tomcat plugin 7.0.5.3 (for run-war)

  App Server:

  • Glassfish 3.0.1 build 22
  • Java 1.6.0_07

  ORM strategy: Table per Subclass

  解决方案

  As my environment overview in the question already seems to imply, it was a problem with the Glassfish application server. I don't know what causes this bug, but this is definitely not expected behaviour.

  I was able to reproduce the same exceptions on deployment in a local Glassfish 3.0.1 environment. Then, fortunately, in a local Glassfish 3.1.2.2 environment, everything worked fine on deployment.

  Grails 1.3.7 runs well on Glassfish 3.0.1; however, after upgrading to Grails 2.4.x (first 2.4.0, then 2.4.1, then 2.4.2), this exception was thrown on deployment. I don't know if it really was the Grails update that caused this to happen -- especially since I made a lot of other changes in the project, e.g. to the domain model, new hibernate version --, but if you run into similar issues with grails 2.4.x and Glassfish deployment, give Version 3.1.2. a shot.

  If I find some time, I will try to create an easy reproducible example and post a JIRA issue. Feel free to create a JIRA yourself if you read this and feel interested about this issue ;).

  I have answered another question of mine that was directly related to the exceptions on deployment.
