Servlet.service() for servlet jsp threw exception javax.servlet.jsp.JspException: No getter method for property: "messageColumn" of bean: "MessageInfo"

其实已经说得很明白了，MessageInfo这个类里的messageColumn属性缺少getter，

所以学好英文很重要。。。

看一下ActionForm中是否对“messageColumn”进行定义了，并有set get方法

Servlet.service() for servlet jsp threw exception javax.servlet.jsp.JspException: No getter method for property: "messageColumn" of bean: "MessageInfo" at 等中可以看到在
MessageInfo这个实体类中messageColumn没有进行封装或者说没有getMessageColumn()方法,所以页面没法调用，解决方案就是在这个MessageInfo对messageColumn进行封装
