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

前天自己尝试着使用 Eclipse3.2+Myeclipse5.5 搭建一个自己的 Struts1.2+Spring2.0+Hibernate3.1 项目框架，这自己不做还不知道，一做就吓了一跳，怎搭个项目框架就这么难，经过整整一天的摸索这才成功的构建了自己想要的项目框架。现在把项目的主要配置文件清单共享如下：

其他的编码和jsp页面就由大家自己补充了，赫赫。。。。。。。

现在把遇到的问题及解决方法跟大家共享，同时欢迎大家指正和给出就意见和建议。遇到的四个问题：

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。

KO。。。！终于可以结束了！ye！
