我已经尝试搜索这个特定的问题并得到了很多答案,但仍然无法找出问题所在。

控制器类:

package com.springforbegineers.controller;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

import com.springforbegineers.domain.Search;
import com.springforbegineers.service.BookService;
@Controller
public class BookController {

    private BookService booksService;

    @Autowired
    public void setBookService(BookService bookService){
        this.booksService = bookService;
    }

    @RequestMapping("/performSearch")
    public String findBooks(Map<String,Object> map , @ModelAttribute("search") Search search){
        map.put("search", search);
        map.put("searchResults", booksService.findBooks(search.getSearchCriteria()));
        return "searchBooks";
    }
}

我无法将 BookService 接口连接到它。

以下是代码清单:

图书服务:

package com.springforbegineers.service;

import java.util.List;

import com.springforbegineers.domain.Books;

public interface BookService {
    void saveBook(Books books);
    List<Books> listBooks();
    List<Books> findBooks(String searchCriteria);
    void removeBook(Integer bookNo);
    Books editBook(Integer bookNo);
}

BookService 实现类:

package com.springforbegineers.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.springforbegineers.dao.BookDAO;
import com.springforbegineers.domain.Books;

@Service
public class BookServiceImpl implements BookService{

    private BookDAO bookDAO;

    @Autowired
    public void setBookDAO(BookDAO bookDAO){
        this.bookDAO = bookDAO;
    }


    @Override
    public void saveBook(Books books) {
        bookDAO.saveBook(books);
    }

    @Override
    public List<Books> listBooks() {
        return bookDAO.listBooks();
    }

    @Override
    public List<Books> findBooks(String searchCriteria) {
        return bookDAO.findBooks(searchCriteria);
    }

    @Override
    public void removeBook(Integer bookNo) {
        bookDAO.removeBook(bookNo); 
    }

    @Override
    public Books editBook(Integer bookNo) {
        return bookDAO.editBook(bookNo);
    }

}

BookDAO 接口:

package com.springforbegineers.dao;

import java.util.List;

import com.springforbegineers.domain.Books;

public interface BookDAO {

    void saveBook(Books books);
    List<Books> listBooks();
    List<Books> findBooks(String searchCriteria);
    void removeBook(Integer bookNo);
    Books editBook(Integer bookNo);
}

BookDAO 实现类:

package com.springforbegineers.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.springforbegineers.domain.Books;

@Repository
public class BookDAOImpl implements BookDAO {

    private SessionFactory sessionFactory;
    @Autowired
    public void setSessionFactory(final SessionFactory sessionFactory) {
      this.sessionFactory = sessionFactory;
    }



    @Override
    public void saveBook(Books books) {
        // TODO Auto-generated method stub

    }

    @Transactional
    @Override
    public List<Books> listBooks() {
        return null;
    }

    @Transactional
    @Override
    public List<Books> findBooks(String searchCriteria) {

         return sessionFactory.getCurrentSession().createQuery("select b from Books b where b.bookName like '%' "+searchCriteria).list();
    }

    @Transactional
    @Override
    public void removeBook(Integer bookNo) {
        // TODO Auto-generated method stub

    }

    @Transactional
    @Override
    public Books editBook(Integer bookNo) {
        // TODO Auto-generated method stub
        return null;
    }

}
