Struts1.2+Spring2.0+Hibernate3.1项目框架构建中的问题及解决方法集锦（2）  

在项目构建是使用MySQL作数据库的过程又出现了两个Bug：

分析：
         No getter method for property userid of bean org.apache.struts.taglib.html.BEAN表明在modules.login.jsp中的表单设计中存在userid属性在对应的actionform bean中找不到对应的属性或者setter/getter方法

解决方法： 
         在actionform bean中加入相应的属性及setter/getter方法。

分析：
          Table 'morecans.morecans__customer' doesn't exist 表明hibernate找不到customer表，这里主要是由于连接mysql时必须提供了数据库名morecans造成找不到数据表。

解决方法：  
          去掉customer.hbm.xml中<class name="com.morecans.test.pojo.Customer" table="customer" catalog="morecans">的catalog="morecans，就可以解决此问题。
