Any Java Enterprise Application that manipulates responses will need to return status codes depending on the execution of the code. So, here is one of the easiest ways to return a status code without the classical numbers like 200, 404, 400, etc.

Following is a complete list of status codes in org.springframework.http.HttpStatus enumeration, you can find more information about it in this link: http://docs.spring.io/spring/docs/3.0.x/api/org/springframework/http/HttpStatus.html.

Hello friend, today I am going to show you how to user a String[] array as an input parameter of a request. This is useful when you want to receive a series of values and then use them for any purpose.

So, let’s get started. Imagine you are creating a controller to read all pages of a CMS given the parent page, but these pages have states as integer values, so you would like to have a method that receives a list of integers (states) and then make a query to the database to get all pages that have the states in the input array.

1) In your controller class you will need to create a method -I would recommend to use Spring annotations-.

Please, pay attention to the line, because that is the one that contains an array of String as input.

In this case, I am setting some default values: “1,2,3” in order to return pages with states 1, 2 or 3 in case the parameter includeStates[] is not present in the request. Of course, you can personalize this method to receive any other parameters.

I hope you find this tip useful for your development.

See you next time and remember, be happy with your code!
