grails与外部配置文件战争tomcat [英] grails war tomcat with external config file

问题描述

我想添加外部配置数据。因此，我在主 Config.groovy 文件中添加了以下行。

我导出了环境变量

  DASH_CONFIG =< path_to_external_configfile> /extConfig.properties 
  

• extConfig.properties
  
  

    simpleBSMDash.default .serverName =test.it.com
   simpleBSMDash.default.refreshInterval =5
    




• Config.groovy

    if（System.getenv（'DASH_CONFIG'））{
   println（ 包括配置文件：+ System.getenv（'DASH_CONFIG'））; 
   grails.config.locations = [
  classpath：exthConfig.properties，
  file：./ extConfig.properties，
  file：$ {System.getenv 'DASH_CONFIG'）}] 
  } else {
   println没有定义外部配置文件。 
  } 
    




• Bootstrap.groovy
  
  

  我在Boostrap.groovy中初始化了一些配置参数。例如

    import org.codehaus.groovy.grails.commons.ConfigurationHolder 
   
   
  新的AdminSettings（
   refreshInterval：$ {ConfigurationHolder.config.simpleBSMDash.default.refreshInterval}，serverName：$ {ConfigurationHolder.config.simpleBSMDash.default.serverName}）。save（failOnError：true）
    

通过以下方式在本地运行应用程序时： grails -Denv = DEV run-app 。一切正常，AdminSettings实例被创建并使用期望的值初始化。

当我在tomcat服务器上部署war文件时，AdminSettings实例未被证明。然而，我没有导出环境变量

  DASH_CONFIG =< path_to_external_configfile> /extConfig.properties。 
  

我将 extConfig.properties 文件在 $ TOMCAT_HOME / lib 文件夹中，它没有工作。

我将它重命名为 extConfig.groovy ，它也没有帮助。

我通过stackflow搜索，但没有找到正确的答案。 >

有没有人有想法？

解决方案

/ p>

在conf / Config.groovy中：

  grails.config.locations = [
classpath：$ {appName} .properties，
file：$ {userHome} /。grails / $ {appName} -config.properties
] 
  

它适用于Windows，尽管Groovy / Windows认为是家（〜）的地方可能有点令人惊讶。您尝试从Config.groovy访问环境变量看起来有点危险......

I want to add external config data. So I added in the main Config.groovy file the following line.

I exported the environment variable

DASH_CONFIG=<path_to_external_configfile>/extConfig.properties

• extConfig.properties

  simpleBSMDash.default.serverName = "test.it.com"
  simpleBSMDash.default.refreshInterval = "5"
  

• Config.groovy

  if(System.getenv('DASH_CONFIG')) {
      println( "Including configuration file: " + System.getenv('DASH_CONFIG'));
      grails.config.locations = [ 
          "classpath:exthConfig.properties",
          "file:./extConfig.properties",
          "file:${System.getenv('DASH_CONFIG')}"]
  } else {
      println "No external configuration file defined."
  }
  

• Bootstrap.groovy

  I'm initialisation some config parameter in Boostrap.groovy. for example

  import org.codehaus.groovy.grails.commons.ConfigurationHolder
  
  
  new AdminSettings(
      refreshInterval:"${ConfigurationHolder.config.simpleBSMDash.default.refreshInterval}", serverName:"${ConfigurationHolder.config.simpleBSMDash.default.serverName}").save(failOnError:true)
  

When running locally the app through: grails -Denv=DEV run-app. Everything works fine, the intance AdminSettings is created and initialised with the expected values.

When I deployed the war file on my tomcat server, the intance AdminSettings is not intantiated. Yet I did export environment variable

DASH_CONFIG=<path_to_external_configfile>/extConfig.properties.

I event put the extConfig.properties file in $TOMCAT_HOME/lib folder, it did not work as well.

I rename it to extConfig.groovy, it did not help either.

I search through stackflow but did not find out a correct answer.

Does anyone have an idea?

解决方案

Here's what works for us:

In conf/Config.groovy:

grails.config.locations = [ 
  "classpath:${appName}.properties", 
  "file:${userHome}/.grails/${appName}-config.properties"
  ]

It works in Windows, though the places Groovy/Windows thinks is home (~) can be a bit surprising. Your attempt to access an environment variable from Config.groovy looks a bit risky...
