本文详细介绍了在使用Spring3+Hibernate4时遇到的NoSessionfoundforcurrentthread错误的解决方法，包括在web.xml中添加特定配置以及调整Junit测试时的事务设置。

spring3+hibernate4出错解决方法如下：在web.xml添加如下配置即可

<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>openSessionInViewFilter</filter-name>
<url-pattern>*.action</url-pattern>

</filter-mapping>

如果用Junit测试的时候总是报No Session found for current thread，这个错误则把

<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
       <tx:attributes>
           <tx:method name="add*" propagation="REQUIRED" />
           <tx:method name="save*" propagation="REQUIRED" />
           <tx:method name="upd*" propagation="REQUIRED" />

<tx:method name="get*" propagation="SUPPORTS" />
           <tx:method name="find*" propagation="SUPPORTS" />
           <tx:method name="load*" propagation="SUPPORTS" />
           <tx:method name="search*" propagation="SUPPORTS" />
       </tx:attributes>
   </tx:advice>

改为：

<tx:method name="get*" propagation="REQUIRED" read-only="true"  />
           <tx:method name="find*" propagation="REQUIRED" read-only="true" />
           <tx:method name="load*" propagation="REQUIRED" read-only="true"  />
           <tx:method name="search*" propagation="REQUIRED" read-only="true"  />
       </tx:attributes>
   </tx:advice>
