在运行SSH项目时，调用dept_list.action和调用dept_delete.action时控制台并未打印异常。而调用add.action和edit.action却在控制台打印如下异常：

异常引起原因 ：
Caused by: No object in the CompoundRoot has a publicly accessible property named 'x' (no setter could be found). - [unknown location]

引起原因：

struts.xml配置中设置devMode=true时，会出现如上述异常。

当devMode=true时，配置为开发者模式。表单所有input标签中的name属性在action中都必须有对应的set/get方法，

无论是input为hidden设置的隐藏域 或者 通过URL传的参数值 。

解决方法：

1、配置<constant name="struts.devMode" value="false" />

2、为各个涉及到的参数设置set/get方法
