Spring MVC Hibernate Web应用程序

Question

Spring MVC + Hibernate web application with mysql database. 3 tables (products, members and cart to connect this two). Members table have two different users: admin and customer. It should be something like Online Store. To have Administrator and Customer users. Admin entering new, edit and delete products. Customer to list all products and add to cart part. But before that it should have log in and sign up part. So Admin or Customer can log in or sign up. So I have welcome page, index.jsp, from which I need links to:

all_products.jsp -> list all products from products table mysql database

signup.jsp -> Add new member form and sending data to members table mysql database.

login.jsp -> Log In form

From login.jsp depending who logged in:

Customer -> index.jsp

Admin -> admin.jsp

admin.jsp -> add.jsp, all_products.jsp with edit and delete option.

add.jsp-> add new product form

I setup up a new project in Netbeans, with Spring mvc and hibernate framework, connect with mysql database, set up server, glassfish... etc...

Then add...

Members.java

public Integer getCartQuantity() {

}

public void setCartQuantity(Integer cartQuantity) {
    this.cartQuantity = cartQuantity;
}

}

I add service also for this classes.

MemberService

package service;

import java.util.List;
import model.Members;

public interface MembersService {
    public void add(Members members);
    public void edit(Members members);
    public void delete(int memberId);
    public Members getMembers(int memverId);
    public List getAllMembers();
}

ProductsService

package service;

import java.util.List;
import model.Products;

public interface ProductsService {
    public void add(Products products);
    public void edit(Products products);
    public void delete(int productId);
    public Products getProducts(int productId);
    public List getAllProducts();
}

Also add ServiceImpl

MembersServiceImpl

package service;

import DAO.MembersDAO;
import java.util.List;
import javax.jms.Session;
import javax.transaction.Transactional;
import model.Members;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;

@Service
public class MembersServiceImpl implements MembersService{

@Autowired
private MembersDAO membersDAO;

@Transactional
public void add(Members members) {
    membersDAO.add(members);
}

@Transactional
public void edit(Members members) {
    membersDAO.edit(members);
}

@Transactional
public void delete(int productId) {
    membersDAO.delete(productId);
}

@Transactional
public Members getMembers(int productId) {
    return membersDAO.getMembers(productId);
}

@Transactional
public List getAllMembers() {
    return membersDAO.getAllMembers();
}

}

ProductsServiceImpl

package service;

import DAO.ProductsDAO;
import java.util.List;
import javax.jms.Session;
import javax.transaction.Transactional;
import model.Products;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;

@Service
public class ProductsServiceImpl implements ProductsService{

@Autowired
private ProductsDAO productsDAO;

@Transactional
public void add(Products products) {
    productsDAO.add(products);
}

@Transactional
public void edit(Products products) {
    productsDAO.edit(products);
}

@Transactional
public void delete(int productId) {
    productsDAO.delete(productId);
}

@Transactional
public Products getProducts(int productId) {
    return productsDAO.getProducts(productId);
}

@Transactional
public List getAllProducts() {
    return productsDAO.getAllProducts();
}

}

And ProductsContoller

package controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import model.Products;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import service.ProductsService;

public class ProductsController extends SimpleFormController {

public ProductsController() {

    setCommandClass(Products.class);
    setCommandName("products");
    setSuccessView("products");
    setFormView("products");
}

 protected ModelAndView products(HttpServletRequest request, HttpServletResponse   response, Object command, BindException errors) throws Exception {
    Products products = (Products) command;
    ModelAndView mv = new ModelAndView(getSuccessView());
    /*ModelAndView addObject = mv.addObject("products",     ProductsService.ProductsService(products.getValue()));*/
    return mv;
}
    @Autowired
    private ProductsService productsService;
    public void setProductsService(ProductsService productsService) {
        this.productsService = productsService;
}

}

Here I am stack.

I also have simple MembersDAO.java, ProductsDAO.java and there implementations.

...and fist question is how to connect two .jsp pages? How to make simple navigation bar to connect first all my .jsp(view) pages? To make simple nav bar on header and use on all my pages. I know i should use spring contorollers...

How to make simple controller that will take me to all_products.jsp from index.jsp and list all products from products table from mysql database???

My app is working and deplopying... I can upload web.xml and servlet.xml but did change things...

Can anyone help me?! Thank you very much.

Answer 1

in your .jsp. create your navigation. If products on href doesn't work. Then add

${pageContext.request.contextPath}/products 

this will be your navigation

<ul>
    <li>
        <a href="${pageContext.request.contextPath}">Home</a>
    </li>
    <li>
        <a href="products">Products</a>
    </li>
    <li>
        <a href="users">Users</a>
    </li>
</ul>

navigation should look like this or depends on what you want

• Home
• Products
• Users

and the simple controller for the views or for your .jsp files.

 @RequestMapping(value = "/home", method = RequestMethod.GET)
            public ModelAndView home() {        
                return new ModelAndView("home"); //home.jsp
            }

@RequestMapping(value = "/products", method = RequestMethod.GET)
    public ModelAndView products() {        
        return new ModelAndView("products");
    }

 @RequestMapping(value = "/users", method = RequestMethod.GET)
        public ModelAndView users() {       
            return new ModelAndView("users");
        }
