ssh框架中遇到的问题总结

错误代码1：DispatchMapping[***] does not define a handler property

在struts配置中，如果用了DispatchAction，则必须加上parameter="status"的参数。：

错误代码2：

  org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in

read-only mode (FlushMode.NEVER) - turn your Session into FlushMode.AUTO or remove 'readOnly'

marker from transaction definition

错误原因:

  OpenSessionInViewFilter在getSession的时候,会把获取回来的session的flush mode 设为FlushMode.NEVER

。然后把该sessionFactory绑定到TransactionSynchronizationManager，使request的整个过程都使用同一个

session，在请求过后再接除该sessionFactory的绑定，最后closeSessionIfNecessary根据该session是否已和

transaction绑定来决定是否关闭session。在这个过程中，若HibernateTemplate 发现自当前session有不是

readOnly的transaction，就会获取到FlushMode.AUTO Session，使方法拥有写权限。

也即是，如果有不是readOnly的transaction就可以由Flush.NEVER转为Flush.AUTO,拥有insert,update,delete

操作权限，如果没有transaction，并且没有另外人为地设flush model的话，则doFilter的整个过程都是

Flush.NEVER。所以受transaction保护的方法有写权限，没受保护的则没有。

解决办法:

  采用spring的事务声明,使方法受transaction控制

    <bean id="baseTransaction"
       class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
          abstract="true">
        <property name="transactionManager" ref="transactionManager"/>
        <property name="proxyTargetClass" value="true"/>
        <property name="transactionAttributes">
            <props>
                <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="save*">PROPAGATION_REQUIRED</prop>
                <prop key="add*">PROPAGATION_REQUIRED</prop>
                <prop key="update*">PROPAGATION_REQUIRED</prop>
                <prop key="remove*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>
    <bean id="userService" parent="baseTransaction">
        <property name="target">
            <bean class="com.phopesoft.security.service.impl.UserServiceImpl"/>
        </property> 
 　　   <property name="target">
            <ref bean ="已定义的bean"/>
        </property>
    </bean>
   但是无论我用什么方法，始终出现上面的exception，经过一天的查找，终于发现...
   在spring的aop服务配置中，包名写错了...
   <aop:config >
    <aop:pointcut id="allManagerMethod" expression="execution (* com.feng.manager.*.*(..))"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod"/>
   </aop:config>
  
   <aop:config >
    <aop:pointcut id="allManagerMethod" expression="execution (* com.feng.Manager.*.*(..))"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod"/>
   </aop:config>

错误原因：从struts中form表单中提交的数据是String类型的，而form中的类型为日期类型，因此不匹配，需要

进行类型转换，在struts中类型转换有两种方式，一种是通过servlet进行注册（不推荐），另外一种是通过插

件的方式注册转换器。
