Alles funktioniert gut , aber wenn ich es ein wenig ändere

Der Hub "/WEB-INF/spring-mvc-servlet.xml" hinzugefügt wurde

<display-name>spring-mvc</display-name> 

    <context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value> 
     /WEB-INF/appconfig-root.xml 
    </param-value> 
    </context-param> 

    <listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    <filter-mapping> 
    <filter-name>encoding-filter</filter-name> 
    <url-pattern>/*</url-pattern> 
    </filter-mapping> 
</web-app>

und der Hub "import resource =" spring-MVC-servlet.xml“gelöscht worden web.xml von /webapp/WEB-INF/appconfig-root.xml

<import resource="appconfig-data.xml"/> 

    <import resource="application-security.xml"/> 

    <context:component-scan base-package="com.hihoall.*"/> 

    <context:property-placeholder location="classpath:database.properties"/> 
</beans>

ich erhalte die Fehler

HTTP Status 500 - org.apache.jasper.JasperException: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

Was soll ich tun, die zweite Variante arbeiten zu machen?

Sie haben bauteil Scannen in mvc Konfigurationsdatei sowie Datenkonfigurationsdatei:

Innen /WEB-INF/spring-mvc-servlet.xml:

<context:component-scan base-package="com.hihoall"/>

Innen /WEB-INF/appconfig-root.xml

<context:component-scan base-package="com.hihoall.*"/>

Da sie die gleichen Pakete scannen, dann die bea ns werden hier zweimal geladen, einmal per mvc config & ein anderer von root config. Sie werden im Web Application Context und im Root Application Context gespeichert.

Jetzt sind die Transaktionsmanagement-Beans in der Root-Konfigurationsdatei definiert (weil Sie /WEB-INF/appconfig-data.xml in der Root-Konfigurationsdatei importieren).

Dies verursacht ein Problem mit Ihrer Anwendung, die Controller-Klassen könnten die Beans aus dem Webanwendungskontext erhalten, die keine Ahnung von Transaktionsverwaltung haben. Wenn Sie also DML-Vorgänge ausführen, schlägt dieser Fehler fehl.
