Answer 1

chanceActionb里的chanceBiz貌似有问题。你的chanceBiz对应的类型也进行了注入了吗？

Answer 2

<!-- DAO -->
<bean id="ChanceDao" class="com.accp.crm.dao.hbnimpl.ChanceDao"
parent="GenericDao" >
<constructor-arg value="com.accp.crm.model.SalChance"></constructor-arg>
</bean> <!-- BIZ -->
<bean id="ChanceBiz" class="com.accp.crm.biz.impl.ChanceBiz">
<property name="chanceDao" ref="ChanceDao"></property>
</bean> <!-- ACTION -->
<bean id="chanceActionb"
class="com.accp.crm.web.action.ChanceAction" scope="singleton">
<property name="chanceBiz" ref="ChanceBiz"></property>
</bean>

Answer 3

<property   name= "chanceDao "   ref= "ChanceDao "> </property> 
<property   name= "chanceBiz "   ref= "ChanceBiz "> </property> 
这两句应该这样写吧
<property   name= "chanceDao ">
  <ref= "ChanceDao "/> 
 </property> 
<property   name= "chanceBiz ">
 <ref= "ChanceBiz"/>
 </property>

Answer 5

<bean   id= "ChanceBiz "   class= "com.accp.crm.biz.impl.ChanceBiz ">
<property   name= "chanceDao "   ref= "ChanceDao "> </property>
</bean> 你的配置文件中有很多空格如id= "ChanceBiz "，name= "chanceDao "都多了一个空格。将所有的空格去掉就好了改成：如id= "ChanceBiz",  name= "chanceDao"

Answer 6

conversion strategy found - action - file:/D:/Tools/apache-tomcat-6.0.32/webapps/crm/WEB-INF/classes/struts.xml:13:46struts.xml中的配置有问题。。看看命令空间的配置等

Answer 7

楼上说的很对，你试试了，你多了空格，同时告诉你一声
设置action的scope为propertype
这是说每次都会创建一个action，而不是单例模式，具体什么错误你自己多看看吧，ssh设计的配置文件太多了，一下子看不过来！

Answer 8

已经解决,是spring aop相关的问题导致biz无法创建,把代理直接交给类来创建就好了
