org.springframework.beans.NotWritablePropertyException: Invalid property
问题：
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'programmaticManager' defined in URL [file:src/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'iTestDao' of bean class [test.ProgrammaticManager]: Bean property 'iTestDao' is not writable or has an invalid setter method. Did you mean 'ITestDao'?
解决方法：
DAO变量名有问题，可能是定义的DAO变量名不符合Struts的什么规范吧。将ITestDao类型变量iTestDao，改成其他名字，就OK了。
