public class bookresourcetest extends jerseytest { @override protected application configure() { enable(testproperties.log_traffic); enable(testproperties.dump_entity); return new resourceconfig().packages("com.example"); } @test public void testgetbook() { book response = target("books").path("1").request().get(book.class); assertnotnull(response); } @test public void testgetbooks() { collection<book> response = target("books").request().get(new generictype<collection<book>>() { }); assertequals(2, response.size()); } }
so seems reason book.java didn't have default constructor jackson unable create instance of it...
public class book { private string id; private string title; private string author; private string isbn; private date published; //must have default constructor public book() { } public book(string id, string title, string author, string isbn, date published) { this.id = id; this.title = title; this.author = author; this.isbn = isbn; this.published = published; } ... }
