Tomcat 6上的Grails 2.3.5 - 兼容性问题？ [英] Grails 2.3.5 on Tomcat 6 - compatibility issues?

问题描述

我想知道是否有人将Tomcat6的Grails 2.3.5部署好了

在BuildConfig中我有 grails.servlet.version = 2.5

插件块如下所示：

  plugins {
 build：release：3.0.1
uild：tomcat：7.0.50
 
 compile：scaffolding：2.0.1 
 compile'：cache：1.1.1'
 
 runtime'：hibernate：3.6.10.7
 runtime：database-migration：1.3.8
 runtime ：jquery：1.10.2.2
 runtime：resources：1.2.1

  

在启动时我收到以下异常：

lockquote
ERROR context.ContextLoader上下文初始化失败
org.springframework .beans.factory.BeanCreationException：错误
在ServletContext中定义了名称为'grailsApplication'的Bean
资源[/WEB-INF/applicationContext.xml]：调用init方法
失败;嵌套异常是java.lang.NoClassDefFoundError：
javax / servlet / AsyncContext

它在Tomcat7上启动得很好。我怀疑hibernate插件是否拖拽了对Servlet 3的依赖关系，但这只是对此阶段的猜测而已。

我升级到最新的小版本解决了这个问题。

• 确保您升级到最新版本的Grails 2.3.x（当前为2.3。 11）。
  和更改application.properties中的值一样简单
  
• 在您的BuildConfig.groovy中，确保设置
  grails.servlet.version =2.5

在这些更改之后，Grails up可以部署到Tomcat 6.0.x容器中。

希望它有助于

I was wondering if anyone had a luck deploying Grails 2.3.5 to Tomcat6

In BuildConfig I have grails.servlet.version = "2.5"

Plugins block looks like following:

plugins {
    build ":release:3.0.1"
    build ":tomcat:7.0.50"

    compile ":scaffolding:2.0.1"
    compile ':cache:1.1.1'

    runtime ":hibernate:3.6.10.7"
    runtime ":database-migration:1.3.8"
    runtime ":jquery:1.10.2.2"
    runtime ":resources:1.2.1"
}

On the startup I get following exception:

ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grailsApplication' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/AsyncContext

It starts up perfectly fine on Tomcat7. I have a suspicion that hibernate plugin is dragging hard dependency on Servlet 3, but that's just a guess at this stage.

解决方案

For me upgrading to latest minor version solve this issue.

• Make sure you upgrade to the latest version of the Grails 2.3.x (currently 2.3.11). It is as easy as changing the value in the application.properties
• In your BuildConfig.groovy make sure to set grails.servlet.version = "2.5"

After these changes the Grails up could be deployed into Tomcat 6.0.x container.

Hope it helps Eduardo
