Я проверяю мою declartive конфигурацию сделки с следующей TestCase:данные, вставленные в БД после весенней операции откатить

Я пытаюсь вставить 2 записи в таблицу с 4-мя столбцами (ID, содержание, должность, время), а положение является УНИКАЛЬНЫМ индексом. Я использую mysql 5.5 с движком innoDB и разрабатываю тест с помощью Spring 3.2.2, Mybatis 3.2.2, Mybatis-Spring 1.2.0. ниже - sql для создания базы данных и таблицы с введенными экспериментальными данными.


    CREATE DATABASE `development` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; 
    USE `development`; 

    CREATE TABLE IF NOT EXISTS `test` (
     `id` int(10) unsigned NOT NULL AUTO_INCREMENT, 
     `content` varchar(256) DEFAULT NULL, 
     `position` int(10) unsigned NOT NULL, 
     `time` int(10) unsigned NOT NULL DEFAULT '0', 
     PRIMARY KEY (`id`), 
     UNIQUE KEY `position` (`position`) 
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=97 ; 

    INSERT INTO `test` (`id`, `content`, `position`, `time`) VALUES (1, 'test', 0, 1368164281),(2, '测试内容', 1, 1368164364),(44, 'bbb', 2, 1368431459),(45, 'ccc', 3, 1368431459),

вы можете увидеть, что при броске исключения, менеджер транзакций катать базу данных обратно, но запись все еще вставить в него.

Есть ли кто-нибудь, кто может сказать, что здесь не так, или это ошибка?

обновленного

Я попытался programatic транзакции с кодом ниже, конечно, комментируйте строки в service.xml отключить АОП и txAdvice. после этого, он работает:

    public synchronized static void init(String path){ 

     init(new String[]{path});

}

обновленный Я сделал небольшое изменение на TestServiceImpl, и он решен, как показано ниже:

private static RecordMapper mapper; 

public void init() { 
    if (null == mapper) { 
     mapper = (RecordMapper) SpringHelper.getBean("recordMapper"); 
    } 
}

Проблема:

Я бы сказал, что проблема в вашей реализации класса SpringHelper и как вы используете его (а именно статическая ссылка в TestServiceImpl). У вас может быть два контекста Spring, инициализированные (симптомы для этого содержатся в первых 4 строках вашего файла журнала).

Почему это не работает:

Transaction + откат в одном контексте, не оказывает никакого влияния на подключение к БД, сделанные другой контекст (оба имеют свои собственные testDataSource и txManager бобы).

Как решить:

Весна рамки инъекции зависимостей, поэтому я не вижу смысла для реализации собственной стратегии подстановки зависимостей. Вы можете проверить аннотацию Autowired на получение depdendencies (например, TestServiceImpl.mapper).

Проверить документацию и демонстрационные проекты весны (например, https://github.com/SpringSource/greenhouse), чтобы узнать, как извлечь максимум из весны. Попробуйте использовать Spring стандартным способом.

Дополнительная АОП проблема:

Btw. ваше определение pointcut неверно, поскольку рекомендации, доступные только для чтения, не покрываются этим.

Я обновил информацию и мой код SpringHelper Class. Можете ли вы предоставить больше советов, спасибо. Я новичок в Spring, и пару лет работал над PHP, совершенно другой. – Snowwolf

Вы сделали это немного хуже. Просто удалите все «статические» объявления в «TestServiceImpl». И следуйте некоторым основным вводным учебникам по весне (убедитесь, что учебники не старые). –
