关于SSH中，spring和hibernate集成问题

[zl198751]

在配置好struts和spring后，我调试过，在jsp页中建立连接 action=“test.do”
< action path="/test" type="org.springframework.web.struts.DelegatingActionProxy" />

< plug-in className="org.springframework.web.struts.ContextLoaderPlugIn"> < set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" /> < /plug-in>

在spring配置文件中：
<bean name="/test" class="com.struts.action.TestAction">
</bean>
测试，可以从jsp页找到TestAction.

然后在SS中继续配置Hibernate后，spring配置中加入了信息
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName"
value="com.mysql.jdbc.Driver">
</property>
<property name="url" value="jdbc:mysql://localhost:3306/test"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>com/hibernate/load/Sys.hbm.xml</value>
<value>com/hibernate/sys/Emp.hbm.xml</value></list>
</property>
</bean>

然后测试就不能找到TestAction了 页面提示ServletAction不可用。
我的配置版本是，MyEclipse6.0 Tomcat5.5 Struts 1.2 Spring2.0 Hibernate3.1 请问大虾是不是这种配置不稳定造成的？谢谢

还有我想补充点，当有时候我在hibernate中加入一个关系表的时候用myeclipse自动生成的DAO可以很好的应用，当用myeclipse加入第二张表的时候就不能使用DAO了，包括原来可以用的也不能了，添加的过程完全是myeclipse自动完成，所以不存在我手工写的错误，不知道是否要在自动完成的基础上改动些后才能正常使用呢？

报什么错误了？看看你tomcat下的log文件的消息

晚上测试还是错误

[avajevol]

应该是spring创建sessionFactory失败造成的,建议你在工程中加入log4j记录日志,可能是缺少某些class

[Javaxy]

你配置文件的关联关系写错了吧！？

[soyestrellafortuna]

Could not read mappings from resource: com/hibernate/Emp.hbm.xml
查查Emp.hbm.xml文件

[happylion2008]

有可能asm包冲突。看一下lib中是不是有两个包：
asm.jar和asm-2.2.3.jar
把asm-2.2.3.jar删除掉看看。

[happylion2008]

另外，加上log4j，看他的DEBUG日志可以找到很多有用的信息。

[zl198751]

就一个asm和asm-attrs.jar log4j我还不太会用 所以没办法发log4j的信息。

谢谢大家了 程序可以运行了 在我尝试的第三台机器上可以运行了 不知道是什么地方的配置问题错误。
