a map contains found methods

getPropertyValue

public static String getPropertyValue(Map<String,String> valueMap,
                                      String propertyName)

gets property value(a string) from a properties map with property name.Three kinds of format conversion are supported on propertyName to get value from properties value map,for example: if input a 'maxActive' propertyName,ordered conversion are below

conversion1(hump): maxActive conversion2(middle-line): max-active conversion2(under_line): max_active
