Glassfish和EclipseLink不能正常工作的entitymanager的Spring注入

我正在使用Java EE，Spring，EclipseLink和Glassfish服務器的Web應用程序。Glassfish和EclipseLink不能正常工作的entitymanager的Spring注入

我的應用程序在我嘗試更改我的bean配置以便爲Spring注入entitymanager並啓用更好的事務管理之前工作得很好...我沒有得到它的工作...（在此之前，我除此之外，我必須在每次數據庫請求之前調用emf.createEntityManager（）。

我不知道關於進口持久性配置和安全 - config ...

爲了確保您擁有所有信息，這裏是MyDAOFactory類，它獲取了entitymanager注：

/** 
* A factory for creating DAO objects. 
*/ 
@Component 
public class MyDAOFactory implements IMyDAOFactory{ 

/** The map dao. */ 
private Map<Class<?>, IDao<?>> mapDAO; 

/** The entity manager. */ 
@PersistenceContext(unitName="databaseName") 
public EntityManager em; 


/** 
* Instantiates a new my dao factory. 
*/ 

public MyDAOFactory() { 

    mapDAO = new HashMap<Class<?>, IDao<?>>(); 

} 


/** 
* Gets the em. 
* 
* @return the em 
*/ 
public EntityManager getEm() { 
    return em; 
} 

/** 
* Sets the em. 
* 
* @param emf the new em 
*/ 
public void setEm(EntityManager em) { 
    this.em = em; 
} 



@Override 
public <T extends Serializable> IDao<T> getBasicDAO(Class<T> entity) { 
    if(mapDAO.containsKey(entity)){ 
     return (IDao<T>) mapDAO.get(entity); 
    }else{ 
     BasicDAO<T> dao = new BasicDAO<T>(entity); 
     dao.setEm(em); 
     mapDAO.put(entity, dao); 
     return dao; 
    } 
} 

}

而定製的UserDetailsS​​ervice：

@Transactional 
    public class MyUserDetailsService implements UserDetailsService { 

    /** The my dao factory. */ 
    IMyDAOFactory myDAOFactory; 

/** 
* Instantiates a new means user details service. 
* 
*/ 
public MyUserDetailsService(IMyDAOFactory myDAOFactory) { 
    this.myDAOFactory = myDAOFactory; 
} 


/* (non-Javadoc) 
* @see org.springframework.security.core.userdetails.UserDetailsService#loadUserByUsername(java.lang.String) 
*/ 
@Override 
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException{ 
    IDao<Utilisateur> userDAO = this.myDAOFactory.getBasicDAO(Utilisateur.class); 
    Map<String, String> map = new HashMap<String, String>(); 
    map.put("loginLdap", username); 
    Utilisateur user = userDAO.findByAttributes(map).get(0); 
    IMyUserDetails userDetails = new MyUserDetails(user.getLoginLdap(), user.getPwdLocal(), user.getActif(), user.getDateValidite().getTime()>System.currentTimeMillis(), true, true, AuthorityUtils.createAuthorityList("ROLE_"+user.getProfil().getNomProfil().toUpperCase())); 
    userDetails.setUser(user); 
    return userDetails;  
} 

}

當我開始在調試模式下的服務器，似乎EntityManager的成立時，myDAOFactory在MyUserDetailsS​​ervice，但不知何故被注入調用loadUserByName不會再發生，當我嘗試登錄到我的應用程序時...（儘管我沒有更改這部分配置...）。

任何幫助將不勝感激！

嘗試了幾天所有可能的配置之後，我終於找到了使用彈簧的EclipseLink和Glassfish我的事務管理一個正確的解決辦法：

  • 主要問題是由於錯誤地使用了spring標記上下文：我在applicationContext.xml中以及在mvc-config.xml中包含的組件掃描。顯然，它創建了兩個不共享bean或事務的上下文（請參閱：Why DispatcherServlet creates another application context?）
  • 我還測試了JTA，jndi：lookup和LocalEntityManagerFactoryBean之間的許多不同配置，但使用Glassfish和EclipseLink似乎使其更具限制性（JTA是唯一可行的選擇）

這裏是我的修正，如果它可以幫助別人一天：

的applicationContext.xml

<beans ...> 

    <import resource="persistence-config.xml"/> 
    <import resource="security-config.xml"/> 

    <context:component-scan base-package="fr.dao, fr.services" /><!-- do not scan the controllers here --> 

    <context:annotation-config/> 


    <!-- Define the location of the property file to change properties dependent on the application environment --> 
    <context:property-placeholder location="/WEB-INF/configuration.properties" /> 

</beans>

MVC-config.xml中

<beans > 


<!-- Spring MVC Support for annotations (JSR-303) --> 
<mvc:annotation-driven> 
    <mvc:argument-resolvers> 
     <bean class="fr.utils.CurrentUserWebArgumentResolver"></bean> 
    </mvc:argument-resolvers> 
</mvc:annotation-driven> 

<context:component-scan base-package="fr.controller" /><!-- only scan controllers here --> 

... 

<import resource="aspects-config.xml"/> 

</beans>

和Persistence-config.xml中：

<beans ...> 

<tx:annotation-driven/> 

<!-- We want to locate the container transaction manager --> 
<bean id="entityManagerFactory" 
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="jpaVendorAdapter"> 
     <bean 
      class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> 
      <property name="showSql" value="true" /> 
     </bean> 
    </property> 
    <property name="jpaDialect"> 
     <bean 
      class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" /> 
    </property> 
    <property name="persistenceUnitName" value="databaseName"/> 
    <property name="persistenceUnitManager"> 
     <bean 
      class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager"/> 
    </property> 
    </bean> 

    <tx:jta-transaction-manager/> 

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/> 
</beans>

幾個要點：

  1. 不要在MVC配置導入安全性和持久性CONFIGS，他們已經在根應用程序上下文中定義（通過進口），其豆可見的MVC上下文

  2. DriverManagerDataSource這個只是測試使用，與真正的池DataSource替換它在生產（如容器管理的DataSource通過JNDI查找）在最新的

  3. 看着你DATAS wece配置，你可能不使用JTA。如果是這樣，請刪除<tx:jta-transaction-manager /> bean定義

  4. 調試以嘗試查明問題。如果是持續性相關的，開始只有持久性（JPA）的東西一個最小的根機應用環境和一個簡單的bean來測試它：

    <bean class="pkg.Test" init-method="persistence" />

  5. 如果你不能得到它的工作，張貼在這裏更多信息

感謝您的建議。我終於搞定了，所以我在下面發佈了正確的配置。再次感謝 – Coralie
