How to read properties file?

[Kousik Majumder]

Hi all,

Can somebody tell me how to get the value of a properties file from a bean class?

i.e:- test.properties in path MyApplication/WEB-INF/test.properties

Utils.java in Path MyApplication/WEB-INF/classes/com/test/Utils.java

I want to access the test.properties file from Utils.java.

Can somebody give the code?

Thanks in advance

Kousik

You could use the ServletContext.getResourceAsStream() method to read the content of the .properties file into a Properties object, using Properties.load() / Properties.loadFromXml(), whichever one is applicable.

Hi,

Not sure if this is what you're looking for:-

    
 
Properties properties = new Properties();
try {
        properties.load(new FileInputStream("filename.properties"));
} catch (IOException e) { }
 

Cheers,
Raj.

There are many ways to read properties file in java. Here explained two way, using

1. ResourceBundle
2. Properties Class

How to use this tutorial
1. Create one directory src and put both below files (MyProp.properties and ReadPropFile.java)

2. MyProp.properties
name = Binod Kumar Suman
roll = 110
city = Bangalore

3. ReadPropFile.java

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Properties;
import java.util.ResourceBundle;


public class ReadPropFile {

public static void main(String[] args) {
getData();
}

public static void getData(){
try{
Properties propertiesFile = new Properties();
propertiesFile.load(new FileInputStream("src/MyProp.properties"));
String studentName = propertiesFile.getProperty("name");
String roll = propertiesFile.getProperty("roll");
System.out.println("Student Name :: "+studentName);
System.out.println("Roll Number :: "+roll);

//Fetch all the Properties.

String key;
Enumeration e = propertiesFile.propertyNames();
while (e.hasMoreElements()) {
key = (String)e.nextElement();
System.out.println(key+" "+propertiesFile.getProperty(key));
}

}catch(IOException e){
e.printStackTrace();
}
}
}


Thanks,
