IntelliJ IDEA comes bundled with
toString() plugin. If you check the plugins in Settings, you should find GenerateToString plugin, which generates
toString() method with options for String concat, StringBuffer, StringBuilder and ToStringBuilder (of Apache Commons) for generating this method.
Google Guava has even better helper method for generating
toString() method for a JavaBean or POJO, which is both clutter free and has a very consistent format; in the form of Objects.toStringHelper(this). It looks more elegant than any of the above solutions, actually. Also, as I make it a point to use Google Guava in all my projects, I have defined the following template in my
toString() method generator settings in IntelliJ IDEA.
Follow the steps mentioned below for adding this template to your IntelliJ IDEA [picked up from SO]:
- Go inside a Java Class in an editor in IntelliJ IDEA.
- Hit Alt + Insert to popup the “Generate” menu.
- Click the “Settings” button.
- Go to the “Templates” tab.
- Create a new template named “Guava toString gen” (or any name you prefer).
- Add the above code to the template.
Yes, its that simple!! After configuring the above template, whenever you want to generate a
toString() method for a Class, IntelliJ IDEA generates
toString() using Guava template you have added just now.
Now, go ahead and give this a try and also check the other method omitNullValues() which might be useful in some scenarios.
