reST (reStructuredText) Question

Restful url through property file

Hello all i have sample restful service below with jersey 2


@XmlRootElement(name = "book")
@XmlType(propOrder = { "id", "name", "author", "price" })
public class Book {

private String id;
private String name;
private String price;
private String author;

public Book() {


public Book(String id, String name, String price, String author) {
super(); = id; = name;
this.price = price; = author;

public String getId() {
return id;

public void setId(String id) { = id;

public String getName() {
return name;

public void setName(String name) { = name;

public String getPrice() {
return price;

public void setPrice(String price) {
this.price = price;

public String getAuthor() {
return author;

public void setAuthor(String author) { = author;


My DAOImpl

public class BooksImpl{
static Connection conn = null;
static Statement stmt;
ResultSet rs;

public List<Book> getAllBooks() throws SQLException, ClassNotFoundException, FileNotFoundException {
List<Book> arrBook = new ArrayList<Book>();
rs = stmt.executeQuery(GET_ALL_BOOKS);
while ( {
arrBook.add(new Book(rs.getString(1), rs.getString(2), rs.getString(3), rs.getString(4)));
return arrBook;


@Produces({ MediaType.APPLICATION_JSON + ";charset=UTF-8",MediaType.APPLICATION_XML + ";charset=utf-8" })
@Consumes({ MediaType.APPLICATION_JSON + ";charset=UTF-8",MediaType.APPLICATION_XML + ";charset=utf-8" })
public class BookServiceImpl implements BookService {

private BooksImpl booksImpl = new BooksImpl();

public Response getBooks(@QueryParam("format") String format) throws SQLException, ClassNotFoundException, FileNotFoundException {
return Response.status(Status.OK).entity(new GenericEntity<List<Book>>(booksImpl.getAllBooks()) {
}).header(HttpHeaders.CONTENT_TYPE, "XML".equalsIgnoreCase(format)
? MediaType.APPLICATION_XML + ";charset=UTF-8" : MediaType.APPLICATION_JSON + ";charset=UTF-8")


So finally i make a get request say in a postman like ::


It's good and i can get the reponse by getting all the books from DB.

my web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"



My requriment is for different http methods we have different url end point paths for example

GET : http://localhost:8080/BooksJAXRS/library
POST : http://localhost:8080/BooksJAXRS/library
DELETE : http://localhost:8080/BooksJAXRS/library/1
PUT : http://localhost:8080/BooksJAXRS/library/1

So i make a props file

DELETE= http://localhost:8080/BooksJAXRS/library/1
PUT= http://localhost:8080/BooksJAXRS/library/1

Now i want to capture that restful url and pass it through props file and route it accordingly depending on the method and url

Thank you

You could create 2 mappings on 2 different methods that call the same private method like this:

public class BookServiceImpl implements BookService {

    public Response getBooksByRoot(@QueryParam("format") String format) {
        return getBooks(format);

    public Response getBooksByLibrary(@QueryParam("format") String format) {
        return getBooks(format);

    private Response getBooks(String format) {

    public Response createBook(@QueryParam("name") String name) {

Response Update:

It seems that you want a dynamic mapping, so you need to use a Path with a regular expression.

public class BookServiceImpl implements BookService {

    public Response getBooks(@PathParam("parameter") String parameter) {
        if (properties.getProperty("GET").endsWith(parameter) {
            // code to get the books here
        } else {
            return Response.status(Response.Status.NOT_FOUND).build();
