+## CRUD на Spring Boot
+
+В этом упражнении мы будем разрабатывать систему управления товарами. Каждый товар находится в какой-либо категории. Вам предстоит создать полный CRUD товара.
+
+### Полезные ссылки
+
+* [Пример приложения на Spring Boot](https://github.com/hexlet-components/java-spring-blog/tree/main)
+
+### src/main/java/exercise/dto
+
+Просмотрите DTO файлы и изучите интерфейс приложения. Обратите внимание, что при просмотре товара мы должны показывать не только *id* категории, в которой он находится, но и название этой категории.
+
+### src/main/java/exercise/mapper/ReferenceMapper.java
+
+Реализуйте маппер для конвертации идентификатора сущности в саму сущность.
+
+### src/main/java/exercise/mapper/CategoryMapper.java
+
+Реализуйте маппер со всеми необходимыми методами для сущности категории.
+
+### src/main/java/exercise/mapper/ProductMapper.java
+
+Реализуйте маппер для со всеми необходимыми методами для сущности товара.
+
+### src/main/java/exercise/controller/ProductController.java
+
+Реализуйте полный CRUD сущности товара. Создайте обработчики для просмотра списка всех задач и конкретной задачи, создания, обновления и удаления товара:
+
+* *GET /products* – просмотр списка всех товаров
+* *GET /products/{id}* – просмотр конкретного товара
+* *POST /products* – добавление нового товара. При указании *id* несуществующей категории должен вернуться ответ с кодом *400 Bad request*
+* *PUT /products/{id}* – редактирование товара. При редактировании мы должны иметь возможность поменять название, цену и категорию товара. При указании *id* несуществующей категории также должен вернуться ответ с кодом *400 Bad request*
+* *DELETE /products/{id}* – удаление товара

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
