Question

我为Tomcat写了一个Grails webapp，它打开并从./data/transactions/foobar上的Berkeley DB中读取。

此代码在我的Eclipse环境中运行良好。

但是当我将它移动到服务器时，它会吐出这个异常。当我将WAR文件中的Grails部署为服务器上的webapps Web应用程序时，我不确定当前工作目录的位置。

com.sleepycat.je.EnvironmentNotFoundException: (JE 4.1.10) ./data/transactions/Foobar
Home directory: ./data/transactions/Foobar ENV_NOT_FOUND: 
EnvironmentConfig.setAllowCreate is false so environment creation is not permitted, but there are no log files in the environment directory. Environment is invalid and must be closed.

Linux服务器上的我的Tomcat安装目录是/ usr / share / tomcat6。 webapps root目录是/ usr / share / tomcat6 / webapps。我们的WAR目录安装在名为“bridge”的子目录中。我的Grails应用程序的WAR路径位于/ usr / share / tomcat6 / webapps / bridge

我尝试将./data/transaction/Foobar放在/ usr / share / tomcat6 / webapps和/ usr / share / tomcat6 / webapps / bridge中，没有运气。

我也尝试将./data/transaction/Foobar放入/ usr / share / tomcat6安装基目录，也没有运气。

以下是我在Tomcat服务器上看到的错误：

Error 500: Executing action [index] of controller[com.ecmhp.ecmdatabridge.generators.GenerateEmiDigestsController] 
caused exception: (JE 4.1.10) ./data/transactions/Foobar 
    Home directory: ./data/transactions/Foobar ENV_NOT_FOUND: 
    EnvironmentConfig.setAllowCreate is false so environment creation is not permitted, but there are no log files in the environment directory. Environment is invalid and must be closed.

Servlet：grails

URI：/bridge/grails/generateEmiDigests/index.dispatch

Home directory: ./data/transactions/Foobar ENV_NOT_FOUND:

知道如何设置Tomcat WAR的当前工作目录，以便找到Berkeley DB ./data/transaction文件吗？或者任何想法我可以找到当前工作目录是我的Grails应用程序？

Answer 1

如果你能掌握'grailsApplication'bean，它可以在Grails框架的不同部分自动注入，你可以尝试：

grailsApplication.mainContext.servletContext.getRealPath('/data/transactions/foobar')

Answer 2

如果您安装Grails的Console插件，则可以运行

new File( 'test.html' ).absolutePath

对于我们的应用程序，这会返回/data/opt/tomcat/5.5/，所以我想你需要将你的目录放在usr / share / tomcat6 / data / transactions中

如何获取Grails / Tomcat Webapp的当前工作目录？
