File Parser

The file parser will take in a file as input parameter and will parse the file based on the delimitter provided. the parsed file will be transformed to an output model as defined in the requirement. Optionally a fileFormat parameter can be passed that can define the datatype format of the columns in the file. If file format not provided, it defaults to the number of columns as 4 and data type formats as below.

Column Datatype 1 date 2 number 3 string 4 double

The application distribution comes as a zip file, when extracted has a lib folder and a config folder. The config folder has a 'application.configuration' file which reads the application properties. We can configure the application port, web context etc.

Steps to run the application:

  1. Unzip the FileParser-0.0.2.0.zip
  2. Open a command prompt and run "java -jar libs/FileParser*.jar > FilePatrser.log"
  3. Using RESTClient like google rest client or postman below endpoint can be invoked.

By default the applications binds to the port 8090 and starts with the web context '/fileParser'. Below are the url (API and UI) and sample payloads for API.

The Application has a minimal UI as it is built with minimal UI knowledge.

UI:

Url: http://localhost:8090/fileParser/

The form will have two text field one for file location and one for delimitter.

On submit a response with each line entry from model will be displayed on the browser. It is not pretty. Sorry for inconvenience.

Sample response: Result: FileParserOutputModel.OutputLine(rowDate=31/3/07 3:32:12 AM EDT, description=Walget's Widgets, value=$50.00) FileParserOutputModel.OutputLine(rowDate=null, description=Walget's Widgets, value=$0.00) FileParserOutputModel.OutputLine(rowDate=2/4/06 2:23:47 PM EDT, description=BMart Bubbles, value=$5.50) FileParserOutputModel.OutputLine(rowDate=18/7/06 1:53:23 PM EDT, description=Kgreen Kandies, value=$0.23) FileParserOutputModel.OutputLine(rowDate=24/12/06 10:0:08 PM EST, description=Santa Snacks, value=$2,000,065.61)
