Запуск хранимой процедуры, которая возвращает данные через Apache Cayenne ORM, не работает

Question

Запуск хранимой процедуры, которая возвращает данные через Apache Cayenne ORM, не работает

Я пытаюсь запустить хранимую процедуру в моей базе данных MariaDB. Я использую Apache Cayenne в качестве ORM. Сообщение об ошибке указывает, что он не может найти хранимую процедуру, но у меня это работает уже для процедур, которые не возвращают данные. Кто-нибудь знаком с хранимыми процедурами и Apache Cayenne, которые могут дать некоторые ориентиры?

Хранимая процедура доступна в файле datamap.map.xml, который использует Cayenne:

<procedure name="copyRecipe" catalog="foodbase" returningValue="true">
    <procedure-parameter name="id_in" type="INTEGER" direction="in"/>
    <procedure-parameter name="id_new" type="INTEGER" direction="out"/>
</procedure>

Я использую следующий код для запуска SP.

  public void copyRecipes() {
        ProcedureQuery query = new ProcedureQuery("copyRecipe");

        // Set "IN" parameter values
        query.addParameter("id_in", recipes.getId());

        // run query
        System.out.println("TEst 1");
        try {
        QueryResponse result = context.performGenericQuery(query);

        System.out.println("Test 2");

        for (result.reset(); result.next();) {
            if (result.isList()) {
                List<String> objIdList = (List<String>) result.currentList();
                Iterator<String> it = objIdList.iterator();


                recipes = getRecipes(it.next());
            } else {
                FacesContext context = FacesContext.getCurrentInstance();

                context.addMessage(null, new FacesMessage("Copy recipe failed"));

            }
        }

        } catch (Exception e) {
            FacesContext context = FacesContext.getCurrentInstance();

            context.addMessage(null, new FacesMessage("Copy recipe failed"));
        }



  }

При запуске метода copyRecipes() Tomcat возвращает следующее сообщение об ошибке:

РЕДАКТИРОВАТЬ: Вот как определяется хранимая процедура:

CREATE DEFINER=`foodbase_admin`@`localhost` PROCEDURE `copyRecipe`(IN `id_in` INT, OUT `id_new` INT)
    NO SQL
    COMMENT 'Copy a recipe w associated ingredients, structure and categories'
BEGIN
#DECLARE id_new INT DEFAULT 0;

INSERT INTO recipes (Username, ID_privileges,Comment,Name,No_of_servings,Instruction,Source,Rating) SELECT Username,ID_privileges,Comment,CONCAT(Name," - copy") AS Name,No_of_servings,Instruction,Source,Rating FROM recipes WHERE ID = id_in;

SELECT LAST_INSERT_ID() INTO id_new;

INSERT INTO ingredients (
 Username,ID_privileges,Comment,ID_recipes,ID_groceries,ID_units,Amount)
    SELECT Username,ID_privileges,Comment,id_new AS ID_recipes,ID_groceries,ID_units,Amount FROM
    ingredients WHERE ID_recipes = id_in;

INSERT INTO recipe_structures (
 Username,ID_privileges,Comment,ID_recipes_super,ID_recipes_sub,Factor,Date)
SELECT Username,ID_privileges,Comment,id_new AS ID_recipes_super,ID_recipes_sub,Factor,Date FROM recipe_structures
WHERE ID_recipes_super = id_in;

INSERT INTO recipe_categories (
    Username,ID_privileges,Comment,ID_recipes,ID_categories)
    SELECT Username,ID_privileges,Comment,id_new AS ID_recipes,ID_categories FROM recipe_categories WHERE ID_recipes = id_in;



END

EDIT2: у меня это работает для другой процедуры. Это выглядит так:

CREATE DEFINER=`foodbase_admin`@`localhost` PROCEDURE `copyStructRecipeIngredients`(IN `id_in` INT, IN `factor` DOUBLE, IN `shoplist_in` INT)
    NO SQL
    SQL SECURITY INVOKER
BEGIN

CALL StructRecipeWeighted(id_in,factor);

#SELECT * FROM structrecipesweighted;

DROP TABLE IF EXISTS tmptbl10;
DROP TABLE IF EXISTS tmptbl11;

CREATE TEMPORARY TABLE tmptbl10 (
Username VARCHAR(255),
ID_privileges int,
ID_groceries int,
ID_units int,
Amount double
    );

INSERT INTO tmptbl10 (Username, ID_privileges, ID_groceries, ID_units, Amount)
SELECT ingredients.Username AS Username, ingredients.ID_privileges AS ID_privileges, ingredients.ID_groceries AS ID_groceries, ingredients.ID_units AS ID_units, structrecipesweighted.Weight*ingredients.Amount AS Amount FROM ingredients
JOIN structrecipesweighted ON ingredients.ID_recipes = structrecipesweighted.ID
    ;

#SELECT * from tmptbl10;

CREATE TEMPORARY TABLE tmptbl11 (
Username VARCHAR(255),
ID_privileges int,
ID_groceries int,
ID_units int,
Amount double,
ID_statuses int
    );

INSERT INTO tmptbl11 (Username, ID_privileges, ID_groceries, ID_units, Amount, ID_statuses)
    SELECT tmptbl10.Username AS Username, tmptbl10.ID_privileges AS ID_privileges, tmptbl10.ID_groceries AS ID_groceries, tmptbl10.ID_units AS ID_units, tmptbl10.Amount AS Amount, groceries.ID_statuses AS ID_statuses
    FROM tmptbl10 JOIN groceries ON tmptbl10.ID_groceries = groceries.ID;

#SELECT * from tmptbl11;

INSERT INTO shoppinglist_items (Username, ID_privileges, ID_shoppinglists, ID_groceries, ID_units, ID_statuses, Amount) 
    SELECT Username AS Username, ID_privileges AS ID_privileges, shoplist_in AS ID_shoppinglists, ID_groceries AS ID_groceries, ID_units AS ID_units, ID_statuses AS ID_statuses, SUM(Amount) AS Amount FROM tmptbl11
    GROUP BY ID_groceries, ID_units
    ;

#SELECT * from shoppinglist_items WHERE ID_shoppinglists = shoplist_in;


END

Я называю это так же:

@SuppressWarnings("unused")
private void copyIngredients(Shoppinglists sl, Recipes base) {

    try {

        ProcedureQuery query = new ProcedureQuery("copyStructRecipeIngredients");
        System.out.println("test e");

        // Set "IN" parameter values
        query.addParameter("id_in", base.getId());
        query.addParameter("factor", base.getNoOfServings());
        query.addParameter("shoplist_in", sl.getId());

        // run query
        QueryResponse result = contextShopList.performGenericQuery(query);
    } catch (Exception e) {
        FacesContext context = FacesContext.getCurrentInstance();

        context.addMessage(null, new FacesMessage("Creation of shopping list fail.\n"+e.getLocalizedMessage()));

    }

Решение

Похоже, Cayenne не может добавить каталог "foodbase" к хранимой процедуре во время вызова. Я подозреваю, что это вызывает ошибку выше. Я открыл сообщение об ошибке в Кайенне. Убедится, что к нему обращаются. На данный момент в свойствах вашего подключения MySQL вы можете добавить имя каталога в строку подключения. Например, jdbc:mysql://127.0.0.1/foodbase . Надеюсь, у вас нет хранимых процедур в нескольких каталогах. В противном случае это не решит проблему.

Это кажется ошибкой при вызове хранимых процедур, которые возвращают значения. В файле datamap.xml я удалил атрибут с именем returningValue="true" в процедуре тега xml. Затем хранимая процедура выполняется в базе данных.

Вот как я изменил файл datamap.xml. Сравните с тем, что в моем вопросе.

<procedure name="copyRecipe" catalog="foodbase">
    <procedure-parameter name="id_in" type="INTEGER" direction="in"/>
    <procedure-parameter name="id_new" type="INTEGER" direction="out"/>

</procedure>
