Where to put a properties file in Java?

Question

I tried to read a .properties file in Java and have the following code:

public final class Config  {
    static {
        Properties properties = new Properties();
        InputStream propertiesStream = Object.class.getResourceAsStream("config.properties");

        if (propertiesStream != null) {
            try {
                properties.load(propertiesStream);
            } catch (IOException e) {
                e.printStackTrace();
            }
        } else {
            System.out.println("file not found");
        }
    }
}

But it keeps saying file not found.

The content of properties is

pwd=passw0rd

Anyone knows how to solve this problem?

It should be in classpath, put it to your root source package, if its a maven project put it to src/main/resources directory

But then changes will require compile. What if we put on fixed path instead? But the drawback will be error if path was not found. Which is better? – stuckedunderflow May 21 '19 at 08:54

it should be in WebContent/Web-Inf/ folder

and in you xml file define the bean like this :

<bean id="propertyConfigurer" class="com.your.project.util.properties.ApplicationProperties">
    <property name="locations">
        <list>
            <value>/WEB-INF/application.properties</value>
        </list>
    </property>
</bean>

if the framework you are using is Spring, then this would work fine – Mitaksh Gupta May 29 '13 at 06:06

Did the OP said he is using spring.? – Stunner Jun 28 '18 at 03:55
I realized that later and I put a comment (before yours) already for the same reason, adding the disclaimer. It might be helpful for a person who stumbles upon this question while working with Spring and facing this same issue. – Mitaksh Gupta Jun 28 '18 at 08:09

You could also keep config.properties in the same folder as Config.java.

//InputStream propertiesStream = Object.class.getResourceAsStream("config.properties");
InputStream propertiesStream   = Config.class.getResourceAsStream("config.properties");

You can have two choices of selecting the path,

Open the file containing folder and get the path and save that path in the string with file like,

InputStream propertiesStream = Object.class.getResourceAsStream(path + File.seperator + "config.properties");
Save the file in src path,

WorkSpace -> Project Name -> Copyhere
