init of spring hibernate project causing errors

votes

I am trying to set up a spring mvc application with a few students for a project at university, it's a web based cookbook.

While Hello World worked, we get some difficult exceptions for our code using hibernate to store the data.

The domain class:

/**
 * POJO which represents a Recipe.
 * @author Nils Sommer
 *
 */
@Entity
@Table(name="recipes")
public class Recipe implements Serializable {

private static final long serialVersionUID = 3239162951065313443L; // generated by       eclipse

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;

@Column(name="title")
private String title;

@Column(name="description")
private String description;

@Column(name="content")
private String content;

@Column(name="preparation_endurance")
private int preparationEndurance;

@Column(name="total_endurance")
private int totalEndurance;

@Column(name="creation")
private Date creation;

private List<Image> images;
private List<Rating> ratings;

// ----- Getters and setters here: -----

}

The Service class:

@Service("recipeService")
@Transactional
public class RecipeService {

protected static Logger logger = Logger.getLogger("service");

@Resource(name="sessionFactory")
private SessionFactory sessionFactory;

public Recipe getRecipe(int id) {
    logger.debug("Retrieving person with id: " + id);

    // Retrieve session from Hibernate
    Session session = sessionFactory.getCurrentSession();

    // Get recipe
    Recipe recipe = (Recipe) session.get(Recipe.class, id);

    // Retrieve recipe
    return recipe;
}

public List<Recipe> getAll() {
    logger.debug("Retrieving all persons");

    // Retrieve session from Hibernate
    Session session = sessionFactory.getCurrentSession();

    // Create a Hibernate query (HQL)
    Query query = session.createQuery("FROM  Person");

    // Retrieve all
    return  query.list();
}

public void add(String title, String description, String content,
        int preparationEndurance, int totalEndurance, Date creation) {
    logger.debug("Adding new person");

    // Retrieve session from Hibernate
    Session session = sessionFactory.getCurrentSession();

    // Create a new Recipe
    Recipe recipe = new Recipe();
    recipe.setTitle(title);
    recipe.setDescription(description);
    recipe.setContent(content);
    recipe.setPreparationEndurance(preparationEndurance);
    recipe.setTotalEndurance(totalEndurance);
    recipe.setCreation(creation);

    // Save
    session.save(recipe);
}

public void delete(Integer id) {
    logger.debug("Deleting existing person");

    // Retrieve session from Hibernate
    Session session = sessionFactory.getCurrentSession();

    // Retrieve existing recipe first
    Recipe person = (Recipe) session.get(Recipe.class, id);

    // Delete 
    session.delete(person);
}

public void edit(Integer id, String title, String description, String content,
        int preparationEndurance, int totalEndurance, Date creation) {
    logger.debug("Editing existing person");

    // Retrieve session from Hibernate
    Session session = sessionFactory.getCurrentSession();

    // Retrieve existing recipe via id
    Recipe recipe = (Recipe) session.get(Recipe.class, id);

    // Assign updated values to this recipe
    recipe.setTitle(title);
    recipe.setDescription(description);
    recipe.setContent(content);
    recipe.setPreparationEndurance(preparationEndurance);
    recipe.setTotalEndurance(totalEndurance);
    recipe.setCreation(creation);

    // Save updates
    session.save(recipe);
}
 }

The Controller class:

package org.cookbookgeeks.webkochbuch.web;

/**
 * @author Nils Sommer
 * 
 * This is the Controller which processes all recipe requests.
 */
@Controller
public class RecipeController {

private static final Logger logger =    LoggerFactory.getLogger(RecipeController.class);

@Resource(name="recipeService")
private RecipeService recipeService;

/**
 * Shows a recipe.
 * @param id of the recipe which wil be shown.
 * @return the view recipe.jsp
 */
@RequestMapping(method=RequestMethod.GET, value="/recipe/{id}")
public String showRecipe(@PathVariable("id") int id, Model model) {
    logger.debug("Returning view recipe with recipe.id=" + id);

    // Get recipe.
    Recipe recipe = recipeService.getRecipe(id);

    model.addAttribute("recipe", recipe);
    return "recipe";
}

/**
 * Adds a recipe and shows it afterwards.
 * @param recipe which is added.
 * @return the view recipe with the id of the created recipe.
 */
@RequestMapping(method=RequestMethod.POST, value="/recipe/add")
public String addRecipe(@ModelAttribute("recipe") Recipe recipe) {
    //TODO: create recipe from post parameter   
    return "/recipe/" + recipe.getId();
}

/**
 * Deletes a recipe and redirects to the start page.
 * @param id of the recipe which gets deleted.
 * @return the view of the start page.
 */
@RequestMapping(method=RequestMethod.GET, value="/recipe/delete/{id}")
public String deleteRecipe(@PathVariable("id") int id) {
    //TODO: delete recipe.
    return "/";
}

/**
 * Edits a recipe and show it afterwards.
 * @param recipe which gets edited.
 * @return the view recipe with the id of the recipe.
 */
@RequestMapping(method=RequestMethod.POST, value="/recipe/edit")
public String editRecipe(@ModelAttribute("recipe") Recipe recipe) {
    //TODO: edit recipe.
    return "/recipe/" + recipe.getId();
}

}

We use the eclipse based spring tool kit sdk and get the following exceptions during startup:

Seems like there is a problem with the recipeService in the Controller class ...

How are you launching this? Is your @Service class getting component-scanned somehow? Post your context configuration. - chrylis -cautiouslyoptimistic-
I think, you do not have servlet defination in web.xml or it is not proper. can you post web.xml? - erencan
@chrylis I just updated the original post with some configuration files we use. Maybe this helps. - nsommer
@Nicktar Don't strip out package declarations as "irrelevant". They're probably the entire issue here. - chrylis -cautiouslyoptimistic-
I'll note that you're doing a lot of explicit naming of things (e.g., the @Service and @Resource names); the problem might just Go Away if you didn't have those there, and you really ought to use constants for that sort of thing. Put a log statement in your RecipeService constructor to see whether the bean is being instantiated at all; that will help you determine whether it's a finding-the-class problem or a graph-resolution problem. - chrylis -cautiouslyoptimistic-

are your using <context:component-scan base-package=""/> ? because your @Service annotation is not recognized by container. please include the packages

The problem is that you have a lot of Spring context files and you're not loading the right one(s). You have a root-context.xml defined and loaded from the web.xml (which I recommend against, even when using XML configuration; if you must, use an import from the specific context XML). Then for your servlet, you're loading servlet-context.xml, which is only component scanning your web package. You need for the context you point Spring at in your web.xml to scan the base package; those app-context.xml and applicationContext.xml files aren't actually getting loaded anywhere.

My recommendation these days is to avoid XML configuration entirely if possible in favor of the JavaConfig system; I have a single main entry-point @Configuration class for my entire application that then component-scans for any other @Configurations.
