如何使用 Groovy 从属性文件中获取值?

How to get values from properties file using Groovy?

我需要一个属性文件 (.properties)，它将文件名作为键，并将它们的目标路径作为值.我需要在运行时解析密钥，具体取决于需要移动的文件.

I require to have a property file (.properties) which would have file names as key, and their destination path as the value. I will need the key to be resolved at runtime, depending on file that needs to be moved.

到目前为止，我似乎能够加载属性，但无法从加载的属性中获取"值.

So far I am able to load the properties it seems but can't "get" the value from the loaded properties.

我提到了线程:groovy:如何访问属性文件? 和以下是我到目前为止的代码片段

I referred to the thread : groovy: How to access to properties file? and following is the code snippet i have so far

def  props = new Properties();
File propFile = 
          new File('D:/XX/XX_Batch/XX_BATCH_COMMON/src/main/resources/patchFiles.properties')
props.load(propFile.newDataInputStream())
def config = new ConfigSlurper().parse(props)
    def ant = new AntBuilder()
    def list = ant.fileScanner {
                fileset(dir:getSrcPath()) {
                    include(name:"**/*")
                }
    }
    for (f in list) {
       def key = f.name
       println(props)
       println(config[key])
       println(config)
       def destn = new File(config['a'])

    }

属性文件现在有以下条目:

the properties file has the following entries for now :

jan-feb-mar.jsp=/XX/Test/1
XX-1.0.0-SNAPSHOT.jar=/XX/Test/1
a=b
c=d

如果我使用 props.getProperty('a') 查找，将返回正确的值或者，配置['a']还尝试了代码:notation

Correct values are returned if I look up using either props.getProperty('a') or, config['a'] Also tried the code: notation

但是一旦切换到使用变量key"，就像在 config[key] 中一样，它返回 --> [:]

But as soon as switch to using the variable "key", as in config[key] it returns --> [:]

我是 groovy 的新手，不能说我在这里错过了什么.

I am new to groovy, can't say what am i missing here.

推荐答案

在我看来你把事情复杂化了太多.

It looks to me you complicate things too much.

这是一个应该可以完成工作的简单示例:

Here's a simple example that should do the job:

对于给定的 test.properties 文件:

a=1
b=2

此代码运行良好:

Properties properties = new Properties()
File propertiesFile = new File('test.properties')
propertiesFile.withInputStream {
    properties.load(it)
}

def runtimeString = 'a'
assert properties."$runtimeString" == '1'
assert properties.b == '2'
