使用spring注入时出现NotWritablePropertyException

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bookmarkManagerService' defined in file [E:\MyCode\bookmark\WebRoot\WEB-INF\classes\applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'bmUserDAO' of bean class [cn.onlysoft.bookmark.BookmarkManagerService]: Bean property 'bmUserDAO' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
