Spring 启动 JSON 响应

Question

Here's my code

@RequestMapping("/bookList") 
public List<Books> list() {
    return bookService.booksList();
}

public class Books {
   private String author;
   private String isbn;
   private String title;
}

Current response

[["TOM",123456,"ABC"],["JANE",789000,"CDE"]]

Expected response

"Books": [
    {"author": "TOM", "isbn": "123456", "title": "ABC"},
    {"author": "JANE", "isbn": "789000", "title": "CDE"}
]

What is the code change I need to make?

Answer 1

Your List<Books> is correctly returned as JSON. Your option would be to wrap it into another object:

public class BookList {
    public List<Books> books;
}

and return a BookList instead of List<Books> .

But to be honest, I would not recommend you do do that. It's not very restful.

Answer 2

session.createQuery returns Object[]. I used Criteria query with projections inside my DAOIMPL class and I got the expected output.
