Spring注入DAO之怪错

spring配置：

<bean name="searchKeywordDAO" class="com.miracle.dm.sdmgr.searchkeyword.dao.impl.SearchKeywordDAOImpl">
     <property name="sqlMapClient" ref="sqlMapClient" />
    </bean>
    
    <bean name="searchWordManager" class="com.miracle.dm.sdmgr.searchkeyword.service.impl.SWordManagerImpl">
        <property name="searchKeywordDAO" ref="searchKeywordDAO"/>
        <property name="sKeywordHibernateDAO" ref="sKeywordHibernateDAO"/>
    </bean>sKeywordHibernateDAO" class="com.miracle.dm.sdmgr.searchkeyword.dao.impl.SKeywordHibernateDAOImpl">
       <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

SWordManagerImpl.java文件注入代码：

SKeywordHibernateDAO sKeywordHibernateDAO;
public SKeywordHibernateDAO getSKeywordHibernateDAO() {
       return sKeywordHibernateDAO;
    }
 
    public voidkeywordHibernateDAO) {
       sKeywordHibernateDAO = keywordHibernateDAO;
    }

启动tomcat服务器，控制台报：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'searchWordManager' defined in ServletContext resource [/WEB-INF/config/applicationContext-sdmgr.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'sKeywordHibernateDAO' of bean class [com.miracle.dm.sdmgr.searchkeyword.service.impl.SWordManagerImpl]: Bean property 'sKeywordHibernateDAO' is not writable or has an invalid setter method. Did you mean 'SKeywordHibernateDAO'?

看来前面的“s”导致问题：把代码修改为：

更改后的代码：
spring配置：

<bean name="searchKeywordDAO" class="com.miracle.dm.sdmgr.searchkeyword.dao.impl.SearchKeywordDAOImpl">
     <property name="sqlMapClient" ref="sqlMapClient" />
    </bean>
    
    <bean name="searchWordManager" class="com.miracle.dm.sdmgr.searchkeyword.service.impl.SWordManagerImpl">
        <property name="searchKeywordDAO" ref="searchKeywordDAO"/>
        <property name="keywordHibernateDAO" ref="keywordHibernateDAO"/>
    </bean>

     <bean name="keywordHibernateDAO" class="com.miracle.dm.sdmgr.searchkeyword.dao.impl.SKeywordHibernateDAOImpl">
       <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

SWordManagerImpl.java文件注入代码：

SKeywordHibernateDAO keywordHibernateDAO;
 public SKeywordHibernateDAO getKeywordHibernateDAO() {
  return keywordHibernateDAO;
 } public void setKeywordHibernateDAO(SKeywordHibernateDAO keywordHibernateDAO) {
  this.keywordHibernateDAO = keywordHibernateDAO;
 }

再次运行，神了没问题了，看来命名不当也会存在问题啊。
