spring+hibernate的session管理问题（openSessionInViewInterceptor）急~

Question

给你个配置,自己看下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName"
value="com.microsoft.sqlserver.jdbc.SQLServerDriver">
</property>
<property name="url"
value="jdbc:sqlserver://localhost:1433;databasename=zf;select Method=cursor">
</property>
<property name="username" value="sa"></property>
<property name="password" value="123456"></property>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="mappingResources">
<list>
<value>com/entity/TblFwxx.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="fwxxDAO" class="com.FwxxDAOImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
</beans>FwxxDAOImpl是业务实现类,实现了
FwxxDAO这个业务接口

Answer 1

<aop:config>
    <!--配置个切入点 就是让SPRING具体要管理哪些类的哪些方法，后面的expression是表达式，用于过滤具体需要哪些类，(* com.xyz.myapp.service *.*(..)) 这句的意思就是对com.xyz.myapp.service包下的所有类的所有任何参数的方法返回值为任何 都应用事务-->
    <aop:pointcut id="businessService" expression="execution(* com.xyz.myapp.service *.*(..))" />
    <aop:advisor pointcut-ref="businessService"
                 advice-ref="tx-advice" />
</aop:config>
<!--配置事务传播特性，下面具体的就是对所有方法，REQUIRED是事务传播特性（这个特性最好去了解一下）-->
<tx:advice id="tx-advice"
    <tx:attributes>
        <tx:method name="*" propagation="REQUIRED" />
    </tx:attributes>
</tx:advice>
你应该都没配置事务，SPRING都不知道改对哪些类的方法应用事务这是我刚才回答给别人的，都是官方文档的东西，针对你的少了对HIBERNATE的加载，配置个BEAN，用classpath:hibernate.cfg.xml这个值把hibernate的东西先注入进来详细的LZ去查下官方文档关于切片那一部分的配置吧

你没有用Proxy

Answer 4

public   final   org.hibernate.SessionFactorybecause   it   is   final看你的代码

Answer 5

<!-- 配置事务 -->
<!-- 事务管理实体 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>

<!-- 事务配置 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 查询方法只读 -->
<tx:method name="find*" propagation="REQUIRED" read-only="true"/>
<!-- 其它方法使用普通事务 -->
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>

<!-- aop切入 -->
<aop:config>
<!--  AspackJ语言 -->
<aop:pointcut expression="execution(* com.sun.service.*.*(..))" id="interCut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="interCut"/>
</aop:config>
给你个配置的示例

Answer 6

是不是你自己在程序中把session关了。
