Spring MVC тесты получить ошибку при загрузке конфигурации контекста

Question

У меня есть веб-приложение, пружинный с файлом контекста, расположенного по адресу

WEB-INF/spring/web-application-context.xml 

Содержание веб-приложения-context.xml выглядит, как показано ниже:

... 
<import resource="data-access-context.xml" /> 
<import resource="security-context.xml" /> 
<import resource="webmvc-context.xml" /> 
... 

Приложение работает нормально. При выполнении теста JUnit, я указать местоположение как это:

@ContextConfiguration(locations= {"file:WebContent/WEB-INF/spring/web-application-context.xml" }) 

Это нормально, но я получил сообщение об ошибке, чтобы загрузить данные-доступ-context.xml, который импортируется в основном веб-контекст файла -Применение-context.xml.

Сообщение об ошибке представлено ниже:

Answer 1

После анализа вам сообщений об ошибках, кажется, вы создаете свой DataSource (в данном доступе context.xml файла) используя JNDI поиска и сделал JNDI на вашем сервере приложений для создания ресурса JNDI. Поэтому, пока вы используете свое веб-приложение , оно отлично работает. Но пока вы пытаетесь запустить тестовые примеры JUnit, это не работает.

Решение

Таким образом, вы можете использовать отдельный файл данных доступа context.xml для запуска тестовых JUnit правильно с указанной ниже конфигурации для «DataSource».

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver"/> 
     <property name="url" value="jdbc:mysql://localhost:3306/cpm?autoReconnect=true" /> 
     <property name="username" value="user" /> 
     <property name="password" value="password" /> 
    </bean> 

В зависимости от базы данных вам необходимо изменить значения. Это всего лишь образец. Надеюсь, что это поможет вам.
