Web servlets

Здраствуйте! изучаю джаву где то месяцев 4 в основном Java se вчера бил на собеседовании на трейни дали задание


Servlet based API for querying text file
As a Product Owner i would like to have Servlet WEB API that will allow me to query/filter
information from text files over web so that
- Any person would have access to file without uploading it on local box
- I can do basic query/filter operations online without using text editor or grep/awk/..
Basically you API should read text file from file system and apply filtering/querying logic to
produce response.
Acceptance criteria:
1. API response content type should be JSON
2. API should have following query params:
- limit: integer which represents max number of chars in text that API should return. If
parameter is blank or missing return max 10000 chars.
- q: string which represents text to search in file, i.e. if it q=java - API should return all
strings which equals to ‘java’ or containing it. If q is blank or missing - API should return
all text from file
- length: integer which represents max string length. API should return string which
doesn’t exceed that number or if there is no such strings empty response. If parameter
is blank or missing ignore it.
- includeMetaData: boolean which if set to true will expose file metadata in API response
alongside textual content. That metadata should contain following: fileName, fileSize (in
KB), fileCreationDate (any format you like, but please not milliseconds since epoch). If
parameter is blank or missing treat it as a ‘false’ value.
Example of API call/response:
/somePath?q=Java&limit=1000&length=5&incl udeMetaData=true
Such call should return all strings that contains ‘Java’ with length <= 5 with total length <=
1000. Additionally metadata will be included.
Example JSON response:
{
"text":[
"Java",
"JavaC"
],
"metaData":{
"fileName":"javaLangSpec.txt",
"fileSize":"900KB",
"fileCreationDate":"January 23, 1996 at 12: 52PM"
}
}
Tech Stack requirements:
1. Servlet 3.1
2. Java 7
3. Tomcat 8.x
1 of 2
Output:
1. WAR file
2. Packaged source file. Please don’t include compiled *.class files
3. Test file with text content
4. Documentation on how to use your application
Constraints:
1. No frameworks like Spring/Jersey should be used
2. API shouldn’t be secured
3. Please remember that your application must be capable of handling few simultaneous
users working with the same file.
