ApplicationContext.xml로 최대 절전 모드를 구성하는 중 오류가 발생했습니다.

Question

Spring의 propertiesPlaceholderConfigurer로 Hibernate를 설정하는 데 문제가 있습니다. 데이터베이스 설정이있는 키 - 값 쌍을 포함하는 db.properties 파일이 있습니다. 이제 Spring의 applicationContext.xml 파일 내에서 Hibernate를 설정해야한다.

내 applicationContext.xml이다 :

는하지만 말, 오류가 계속누군가가 해결책을 가르쳐 주거나 나에게 무엇이 잘못 될 수 있는지 말해 주시면 감사하겠습니다.

미리 감사드립니다.

나자르. 오류의 근본 원인 때문에

Answer 1

: 당신이 속성 dialect 파일을 제대로 정의되지 않은 것처럼

org.hibernate.HibernateException: Hibernate Dialect must be explicitly set

이 보인다, 그것은 필수 속성입니다.

세션 팩토리를 구성하는 방법 (코드에 표시되지 않음)은 무엇입니까? 당신은 예를 들어, buildSessionFactory 전에 configure()가 호출 전화를해야합니다

new AnnotationConfiguration().configure().buildSessionFactory(); 

는 특정 구성을로드하려면 :

디폴트있는 hibernate.cfg.xml을로드하려면이있는 것처럼

new AnnotationConfiguration().configure("hibernate-specific.cfg.xml")..buildSessionFactory(); 

Answer 2

보인다 방언이 누락되었습니다 :

Caused by: org.hibernate.HibernateException: Hibernate Dialect must be explicitly set 

이 정보를 추가하면 도움이 될 수 있습니다.

  <prop key="hibernate.dialect"> 
       org.hibernate.dialect.SQLServerDialect //add your specific dialect 
      </prop> 

최대 절전 모드 속성 중 하나입니다. 당신의 재산에

<property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">${db.dialect}</prop> 
      <prop key="hibernate.show_sql">${db.show_sql}</prop> 
      <prop key="hibernate.hbm2ddl.import_files">${db.import_files}</prop> 
      <prop key="hibernate.hbm2ddl.auto">${db.hbm2ddl_auto}</prop> 
      <prop key="connection.pool_size">${db.pool_size}</prop> 
      <prop key="current_session_context_class">${db.current_session_context_class}</prop> 
      <prop key="hibernate.cache.provider_class">${db.provider_class}</prop> 
      <prop key="hibernate.cache.use_second_level_cache">${db.use_second_level_cache}</prop> 
      <prop key="hibernate.cache.use_query_cache">${db.use_query_cache}</prop> 
     </props> 
    </property> 

넣어이 : 등록 정보 파일을로드하는 방법

db.dialect=org.hibernate.dialect.PostgreSQLDialect 

:

는

<bean id="propertyConfigurer" 
     class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" 
     p:location="/WEB-INF/connection.properties" /> 

세션 공장의 예 :

<bean id="XXX" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" 
     p:dataSource-ref="XXX" > 
    <property name="annotatedClasses"> 
     <list> 
      <value>XXX</value> 
     </list>  
    </property> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect"> 
       XXX 
      </prop> 
      <prop key="hibernate.show_sql">false</prop> 
     </props> 
    </property> 
</bean> 

이 중요한 부분입니다 세션 팩토리 선언의 :

AnnotationSessionFactoryBean 

Answer 3

문제가 다른 곳에 숨겨져 있습니다.내 응용 프로그램 (Facelets/Managed Beans)은 Spring에 의해 전혀 관리되지 않았습니다. web.xml 파일에 다음 라인을 추가 한 후, 모든 일 : - 당신은 서블릿을 사용하는 경우

<application> 
     <el-resolver> 
      org.springframework.web.jsf.el.SpringBeanFacesELResolver 
     </el-resolver> 
</application> 

/JSP 대신의 DispatcherServlet을 추가

<servlet> 
    <servlet-name>example</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>example</servlet-name> 
    <url-pattern>*.form</url-pattern> 
</servlet-mapping> 

희망이 언젠가는 누군가가 도움이 될 것이다. 내가 명시 적으로이 같은 사투리를 최대 절전 모드로 값을 할당 할 경우에도
