将配置文件application.yml转换为Grails 3.x中的application.groovy [英] convert configuration file application.yml to application.groovy in Grails 3.x

问题描述

我正在尝试创建一个简单的Grails 3项目，并且遇到了一些非常简单的事情。所以我希望我的数据源属性来自我在IntelliJ IDE中设置的VM选项。在使用Grails 2.x之前，我只是习惯于这样做：

  environments {
 development {
 //数据库连接属性
 def dbserver = System.properties.getProperty（'dbserver'）
 def dbport = System.properties.getProperty（'dbport'）
 ...... ...... 
 dataSource {
 url：jdbc：sqlserver：// $ {dbserver}：$ {dbport}; databaseName = $ {dbname} 
} 
 } 
  

现在我有application.yml，如何访问System.properties并将其嵌入在yml中？我已经读过，如果YML不支持它，我们可以使用application.groovy，在这种情况下，这就是application.groovy的样子：

  grails {
 profile ='web'
 codegen {
 defaultPackage ='defPack'
} 
} 
 
 info {
 app {
 name ='@ info.app.name @'
 version ='@info.app .version @'
 grailsVersion ='@ info.app.grailsVersion @'
} 
} 
 
 spring {
 groovy {
 template ['check-template-location'] = false 
} 
} 
 
 hibernate {
 naming_strategy ='org.hibernate.cfg.DefaultNamingStrategy'
缓存{
 queries = false 
} 
} 
 
 grails {
 mime {
 disable {
 accept {
 header {
 userAgents = ['Gecko'，'WebKit'，'Presto'，'Trident'] 
} 
} 
} 
 
类型{
 all ='* / *'
 atom ='application / atom + xml'
 css ='text / css'
 csv ='text / csv'
 form ='application / x-www-form-urlencoded'
 html = ['text / html'，'application / xhtml + xml'] 
 js ='text / javascript' 
 json = ['application / json'，'text / json'] 
 multipartForm ='multipart / form-data'
 rss ='application / rss + xml'
 text ='text / plain'
 hal = ['application / hal + json'，'application / hal + xml'] 
 xml = ['text / xml'，'application / xml'] 
 
 $ b $ urlmap {b $ b cache {
 maxsize = 1000 
} 
} 
控制器{
 defaultScope =' singleton'
} 
转换器{
 encoding ='UTF-8'
} 
 views {
 default {codec ='html'} 
 gsp {
 encoding ='UTF-8'
 htmlcodec ='xml'
编解码器{
表达式='html'
 scriptlets ='html'
 taglib ='none'
 staticparts ='none'
 } 
} 
} 
} 
 dataSource {
 pooled = true 
 jmxExport = true 
 driverClassName ='com.microsoft.sqlserver.jdbc .SQLServerDriver'
 dbCreate =''
 username ='someUsername'
 password ='somePass'
} 
 environments {
 development {
 dataSource {
 url ='jdbc：sqlserver：// localhost：1234; databaseName = someDbName;'
} 
} 
} 
  
 p> 
 
 
谢谢。 
 
 
 更新： 
 
 
 
 application.groovy没有被默认引用，即使我删除了application.yml    
 
解决方案
 <原来我有一个问题，我需要在引号中加上'default'关键字。像： 
 
 
  grails {
 profile ='web'
 codegen {
 defaultPackage =' defPack'
} 
} 
 
信息{
 app {
 name ='@ info.app.name @'
 version =' @ info.app.version @'
 grailsVersion ='@ info.app.grailsVersion @'
} 
} 
 
 spring {
 groovy {
 template ['check-template-location'] = false 
} 
} 
 
 hibernate {
 naming_strategy ='org.hibernate.cfg.DefaultNamingStrategy' 
 cache {
 queries = false 
} 
} 
 
 grails {
 mime {
 disable {
 accept {
 header {
 userAgents = ['Gecko'，'WebKit'，'Presto'，'Trident'] 
} 
} 
} 
 
 types {
 all ='* / *'
 atom ='application / ato m + xml'
 css ='text / css'
 csv ='text / csv'
 form ='application / x-www-form-urlencoded'
 html = [ 'text / html'，'application / xhtml + xml'] 
 js ='text / javascript'
 json = ['application / json'，'text / json'] 
 multipartForm = 'multipart / form-data'
 rss ='application / rss + xml'
 text ='text / plain'
 hal = ['application / hal + json'，'application / hal + xml'] 
 xml = ['text / xml'，'application / xml'] 
} 
} 
 urlmapping {
 cache {
 maxsize = 1000 
} 
} 
控制器{
 defaultScope ='singleton'
} 
转换器{
编码='UTF-8'
} 
 views {
'default'{codec ='html'} //这是错误的来源
 gsp {
 encoding ='UTF-8'
 htmlcodec ='xml'
编解码器{
表达式='html'
 scriptlets ='html'
 taglib ='none'
 staticparts ='none'
} 
} 
} 
} 
 
 def dbserver = System.properties.getProperty （'dbserver'）
 def dbport = System.properties.getProperty（'dbport'）
 def dbusername = System.properties.getProperty（'dbusername'）
 def dbpassword = System.properties。 getProperty（'dbpassword'）
 def dbname = System.properties.getProperty（'dbname'）
 
 dataSource {
 pooled = true 
 jmxExport = true 
 driverClassName ='com.microsoft.sqlserver.jdbc.SQLServerDriver'
 dbCreate =''
 username = dbusername 
 password = dbpassword 
} 
 environments {
开发{
 dataSource {
 url ='jdbc：sqlserver：// $ {dbserver}：$ {dbport}; databaseName = $ {dbname}'
} 
} 
} 
  
 
I am trying to create a simple Grails 3 project and got stuck with something really simple. So I want my data source properties to come from VM options that I set in my IntelliJ IDE. Before in Grails 2.x, I just used to do something like:
environments {
    development{
        //Database connection properties
        def dbserver = System.properties.getProperty('dbserver')
        def dbport = System.properties.getProperty('dbport')
        ............
        dataSource {
            url: "jdbc:sqlserver://${dbserver}:${dbport};databaseName=${dbname}
        } 
    }
Now that I have application.yml, how do I access "System.properties" and embed it in yml? I have read that we can instead use application.groovy if YML doesn't support it, in that case this is what the application.groovy looks like :
grails {
    profile = 'web'
    codegen {
        defaultPackage = 'defPack'
    }
}

info {
    app {
        name = '@info.app.name@'
        version = '@info.app.version@'
        grailsVersion = '@info.app.grailsVersion@'
    }
}

spring {
    groovy {
        template['check-template-location'] = false
    }
}

hibernate {
    naming_strategy = 'org.hibernate.cfg.DefaultNamingStrategy'
    cache {
        queries = false
    }
}

grails {
    mime {
        disable {
            accept {
                header {
                    userAgents = ['Gecko', 'WebKit', 'Presto', 'Trident']
                }
            }
        }

        types {
            all = '*/*'
            atom = 'application/atom+xml'
            css = 'text/css'
            csv = 'text/csv'
            form = 'application/x-www-form-urlencoded'
            html = ['text/html', 'application/xhtml+xml']
            js = 'text/javascript'
            json = ['application/json', 'text/json']
            multipartForm = 'multipart/form-data'
            rss = 'application/rss+xml'
            text = 'text/plain'
            hal = ['application/hal+json', 'application/hal+xml']
            xml = ['text/xml', 'application/xml']
        }
    }
    urlmapping {
        cache {
            maxsize = 1000
        }
    }
    controllers {
        defaultScope = 'singleton'
    }
    converters {
        encoding = 'UTF-8'
    }
    views {
        default { codec = 'html' }
        gsp {
            encoding = 'UTF-8'
            htmlcodec = 'xml'
            codecs {
                expression = 'html'
                scriptlets = 'html'
                taglib = 'none'
                staticparts = 'none'
            }
        }
    }
}
dataSource {
    pooled = true
    jmxExport = true
    driverClassName = 'com.microsoft.sqlserver.jdbc.SQLServerDriver'
    dbCreate = ''
    username = 'someUsername'
    password = 'somePass'
}
environments {
    development {
        dataSource {
            url = 'jdbc:sqlserver://localhost:1234;databaseName=someDbName;'
        }
    }
}
Thanks.


UPDATE:

application.groovy is not being taken in by default, even when I removed application.yml
解决方案
Turned out I had an issue, I needed to put 'default' keyword within quotes. Like :
grails {
    profile = 'web'
    codegen {
        defaultPackage = 'defPack'
    }
}

info {
    app {
        name = '@info.app.name@'
        version = '@info.app.version@'
        grailsVersion = '@info.app.grailsVersion@'
    }
}

spring {
    groovy {
        template['check-template-location'] = false
    }
}

hibernate {
    naming_strategy = 'org.hibernate.cfg.DefaultNamingStrategy'
    cache {
        queries = false
    }
}

grails {
    mime {
        disable {
            accept {
                header {
                    userAgents = ['Gecko', 'WebKit', 'Presto', 'Trident']
                }
            }
        }

        types {
            all = '*/*'
            atom = 'application/atom+xml'
            css = 'text/css'
            csv = 'text/csv'
            form = 'application/x-www-form-urlencoded'
            html = ['text/html', 'application/xhtml+xml']
            js = 'text/javascript'
            json = ['application/json', 'text/json']
            multipartForm = 'multipart/form-data'
            rss = 'application/rss+xml'
            text = 'text/plain'
            hal = ['application/hal+json', 'application/hal+xml']
            xml = ['text/xml', 'application/xml']
        }
    }
    urlmapping {
        cache {
            maxsize = 1000
        }
    }
    controllers {
        defaultScope = 'singleton'
    }
    converters {
        encoding = 'UTF-8'
    }
    views {
        'default' { codec = 'html' }//THIS WAS THE SOURCE OF ERROR
        gsp {
            encoding = 'UTF-8'
            htmlcodec = 'xml'
            codecs {
                expression = 'html'
                scriptlets = 'html'
                taglib = 'none'
                staticparts = 'none'
            }
        }
    }
}

def dbserver = System.properties.getProperty('dbserver')
def dbport = System.properties.getProperty('dbport')
def dbusername = System.properties.getProperty('dbusername')
def dbpassword = System.properties.getProperty('dbpassword')
def dbname = System.properties.getProperty('dbname')

dataSource {
    pooled = true
    jmxExport = true
    driverClassName = 'com.microsoft.sqlserver.jdbc.SQLServerDriver'
    dbCreate = ''
    username = dbusername
    password = dbpassword
}
environments {
    development {
        dataSource {
            url = 'jdbc:sqlserver://${dbserver}:${dbport};databaseName=${dbname}'
        }
    }
}
