混合声明性bean和注释的bean：org.hibernate.HibernateException没有找到当前线程的会话 [英] Mixing declarative beans and annotated beans: org.hibernate.HibernateException No Session found for current thread

问题描述

我得到没有找到当前线程的会话。
我想问题在于混合声明式xml bean和带注释的bean。
下面，我将继续我的配置。

MyLibrary项目

Spring 3.1.4
Hibernate 4

applicationContext.xml

 < tx：annotation-driven transaction-manager =transactionManager/> 
 
< context：component-scan 
 base-package =com.mycompany.dao.core，com.mycompany.services.core，
 com.mycompany.permissionEvaluator /> 
 
< import resource =model-core-security.xml/> 
 
< bean id =transactionManager
 class =org.springframework.orm.hibernate4.HibernateTransactionManager> 
< property name =sessionFactoryref =sessionFactory/> 
< / bean> 
 ...（sessionFactory ecc ...）
  

model-core- security.xml

 < bean id =expressionHandler
 class =org.springframework。 security.access.expression.method.DefaultMethodSecurityExpressionHandler> 
< property name =permissionEvaluatorref =permissionEvaluator/> 
< / bean> 
 
< security：全局方法安全性
 pre-post-annotations =enabled> 
< security：expression-handler ref =expressionHandler/> 
< / security：global-method-security> 
  

使用组件扫描，我创建了Bean：AccountService，AccountDAO和PermissionEvaluator。

AccountService.java（com.mycompany.services）

  @ Service（accountService）
 @Transactional 
 public class AccountServiceImpl implements AccountService {
 
 @Resource 
 private AccountDAO accountDAO; 
 
 ... 
} 
  

AccountDAO。 java（com.mycompany.dao）

  @Repository 
 @Transactional 
 public class HibernateAccountDAOImpl implements AccountDAO {
 
 ... query ... 
} 
  

（AccountService e AccountDAO是事务性的）

现在，在 AccountController.java 中，我调用了 accountService.listAccounts（）但是，如果我将AccountService注入PermissionEvaluator类（以下代码段），则AccountController将获取没有会话 ！

当调用时 accountService.listAccounts（）

$ b

PermissionEvaluator.java（com.mycompany.permissionEvaluator）
$ b

 组件（permissionEvaluator）
公共类PermissionEvaluatorImpl实现PermissionEvaluator {
 
 @Resource 
私人帐户服务帐户服务; 
 
 ... 
} 
  

我使用PermissionEvaluator AccountService，AccountDAO）由model-core-security.xml中声明的expressionHandler bean中的component-scan创建。

可能是没有找到currend线程的会话的原因吗？

解决方案您可以通过以下方式联系我们：http：//www.businesswire.com/cgi-bin/mmg.cgi？eid = 0>

你可以尝试导入import javax.transaction.Transactional;

I get "No Session found for current thread". I suppose the problem is in mixing declarative xml beans and annotated beans. Following, I'll resume my config.

MyLibrary Project

Spring 3.1.4 Hibernate 4

applicationContext.xml

<tx:annotation-driven transaction-manager="transactionManager" /> 

<context:component-scan 
    base-package="com.mycompany.dao.core, com.mycompany.services.core,
                  com.mycompany.permissionEvaluator" />

<import resource="model-core-security.xml" />

<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
... (sessionFactory ecc...)

model-core-security.xml

<bean id="expressionHandler"
class="org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler">
    <property name="permissionEvaluator" ref="permissionEvaluator" />
</bean>

<security:global-method-security
    pre-post-annotations="enabled">
    <security:expression-handler ref="expressionHandler" />
</security:global-method-security>

With component-scan I create beans: AccountService, AccountDAO and PermissionEvaluator.

AccountService.java (com.mycompany.services)

@Service("accountService")
@Transactional
public class AccountServiceImpl implements AccountService {

    @Resource
    private AccountDAO accountDAO;

   ...
}

AccountDAO.java (com.mycompany.dao)

@Repository
@Transactional
public class HibernateAccountDAOImpl implements AccountDAO {

   ...query...
}

(AccountService e AccountDAO are transactional)

Now, within AccountController.java I call accountService.listAccounts() and it's all right!

But, if I inject AccountService into PermissionEvaluator class (following snippet), AccountController gets No Session found for current thread when invokes accountService.listAccounts()

PermissionEvaluator.java (com.mycompany.permissionEvaluator)

Component("permissionEvaluator")
public class PermissionEvaluatorImpl implements PermissionEvaluator {

    @Resource
    private AccountService accountService;

    ...
}

I use PermissionEvaluator (with AccountService, AccountDAO) created by component-scan in expressionHandler bean declared in model-core-security.xml.

Might it be the cause of "no session found for currend thread"?

解决方案

@Transactional what's ur import package

import org.springframework.transaction.annotation.Transactional; ??

U can try to import "import javax.transaction.Transactional;"
