[英]groovy MissingMethodException - parsing through ConfigSlurper
I am trying to parse through some properties file using configslurper. 我正在尝试使用configslurper解析一些属性文件。
ENT.adminserver.nodenumber=1
ENT.managedserver.1.host=vserver04
ENT.managedserver.2.host=vserver05
ENT.managedserver.3.host=vserver08
ENT.managedserver.4.host=vserver07
Said properties file. 表示属性文件。 I am trying to read the host names from the properties.
我正在尝试从属性中读取主机名。
Properties properties = new Properties()
File propertiesFile = new File('DomainBuild.properties')
propertiesFile.withInputStream {properties.load(it)}
def config = new ConfigSlurper().parse(properties)
def domainname="ENT" //will be passed through paremeters
def domain = config.get(domainname)
def managedServerFlow= {
println domain.managedserver
println domain.managedserver.keySet()
domain.managedserver.each {
println it.getClass()
println it.get("1")
}
for (server in domain.managedserver) {
println server.getClass()
println server
}
}
}
the it.get("1") is causing the following error. it.get(“ 1”)导致以下错误。
No signature of method: java.util.LinkedHashMap$Entry.get() is applicable for argument types: (java.lang.String) values: [1]
Possible solutions: getAt(java.lang.String), grep(), grep(java.lang.Object), wait(), getKey(), any()
I looked through the java and groovy doc and spent few hours without resolution. 我浏览了Java和groovy文档,花了几个小时没有解决问题。 Please help.
请帮忙。
Instead of 代替
println it.get("1")
Try 尝试
println it.'1'
Or 要么
println it.getAt("1") // as the exception shows you
Think about what types you are working with. 考虑一下您正在使用哪种类型。
config
is a ConfigObject
, which you can treat like a map. config
是ConfigObject
,您可以将其视为地图。 Its sub-objects domain
and domain.managedserver
are also ConfigObjects. 它的子对象
domain
和domain.managedserver
也是ConfigObjects。 When you call each
on domain.managedserver
and pass it a closure that takes no parameters, it gives you a set of Entries. 当您在
domain.managedserver
上调用each
domain.managedserver
并将其传递给不带任何参数的闭包时,它将为您提供一组条目。 Therefore you can't call it.get("1")
because an Entry
doesn't have a property called "1". 因此,您不能调用它
it.get("1")
因为Entry
没有名为“ 1”的属性。 It has key
and value
. 它具有
key
和value
。 So you can either println "$it.key: $it.value"
or 因此,您可以
println "$it.key: $it.value"
或
domain.managedserver.each { key, value ->
println value.getClass()
println "$key: $value"
}
or if you want to get the value for key "1" directly: 或者如果您想直接获取键“ 1”的值:
println domain.managedserver.'1'
