In order to call the properties all you have to do is use the Properties instance to call and use the method getProperty() to obtain the said property.Īs you can see we are simply using the getProperty() method of Properties class to retrieve information from the config.properties file. Now let’s see how we are going to use it in our code. The above line will load the file input stream LOCAD PROPERTY FILE TO JAVA CLASS CODEYou can do so by simply adding a piece of code which takes InputStream as a parameter. Step 5: Now is the time to actually load the config.properties file. LOCAD PROPERTY FILE TO JAVA CLASS HOW TOIf you aren’t sure how to handle exceptions, feel free to check out that tutorial as well. You might also have to use try catch to handle exceptions: Make sure you import java.io for it to work: Replace the FILEPATH with the actual path of your config file. Step 4: Time to instantiate it: fis = new FileInputStream( FILEPATH) Step 3: Now you need to make Eclipse take the inputs from it using an Input Stream or really you can use any method described in how to read a file tutorial.įor that we will initialize FileInputStream first and then instantiate it in a similar manner:įirst we will initialize it. I made use of ConfigurationProperties('xxx') but it is not working. Step 2: Now instantiate it by calling the constructor of Properties. I am trying to define a property in application.properties file in java and trying to access it in another custom class which I made and it is not getting the properties. Or put your mouse cursor on Properties and it will flare options to consider. If you notice an error popping up at Properties, just import the following: import Step 1: Type the following in your class: Properties config Here are the steps:įirst of all, we need to initialize properties. This is the next important step while working with config.properties file. Loading properties is important or your Eclipse would treat it as just an unclaimed file. Now you can load these properties to be used in your code. Step 4: Provide properties in your config.properties file: I will just go ahead and add some properties that I may need for my code in the long run. It will create a blank properties file for you where you can now store all your properties to be extracted whenever you need an input somewhere in your code. Step 2: Then in the New File dialog box, in the text box File Name, type the name as “config.properties”: Step 1: Right click on the folder you wish to place your config file in and then click on New> File How to Create a config.properties file in Eclipse In here, we are going to see exactly that – how to create a config.properties file in Eclipse, load it and then use it effectively. It is a good coding practice to use a config.properties file where you can store all your fixed client requirements and use your code to call each values using the getProperty() method. So that you retrieve your data using your code, so that nothing is hard coded. You see it’s a good idea to place all your properties in a different file. In this case actual file is present in location /bin/com/howtodoinjava/io/demo.txt.ĭrop me your questions related to reading a file from the classpath in Java.In here we are going to see how to create a config.properties file in Eclipse and how to load it and bring it in use.
