Set multiple system properties Java command line
Is there an easier way to specify multiple System Properties on the command line to a Java program rather than having multiple -D statements?
Trying to avoid this:
java -jar -DNAME="myName" -DVERSION="1.0" -DLOCATION="home" program.jar
I thought I had seen an example of someone using one -D
and some quoted string after that, but I can't find the example again.
Solution 1:
Answer is NO. You might have seen an example where somebody would have set something like :
-DArguments=a=1,b=2,c=3,d=4,e=cow
Then the application would parse value of Arguments
property string to get individual values.
In your main
you can get the key values as(Assuming input format is guaranteed):
String line = System.getProperty("Arguments");
if(line != null) {
String str[] = line.split(",");
for(int i=1;i<str.length;i++){
String arr[] = str[i].split("=");
System.out.println("Key = " + arr[0]);
System.out.println("Value = " + arr[1]);
}
}
Also, the -D
should be before the main class or the jar
file in the java command line. Example : java -DArguments=a=1,b=2,c=3,d=4,e=cow MainClass
Solution 2:
There's nothing on the Documentation that mentions about anything like that.
Here's a quote:
-Dproperty=value Set a system property value. If value is a string that contains spaces, you must enclose the string in double quotes:
java -Dfoo="some string" SomeClass
