org/springframework/web/servlet/ModelAndView类与org/springframework/web/portlet/ModelAndView之间的区别 [英] Difference between org/springframework/web/servlet/ModelAndView class and org/springframework/web/portlet/ModelAndView
问题描述
我刚刚回答了以下有关此已发布问题的问题.
I have just answered the below question which revolves around this posted question.
spring mvc InternalResourceViewResolver没有前缀
有人可以说出课程之间的区别
Can someone out there tell the difference between the classes
org/springframework/web/servlet/ModelAndView 和 org/springframework/web/portlet/ModelAndView
我都看到了几乎相似的API文档
I see almost similar API docs for both
和
都具有构造函数
ModelAndView(String viewName)
Convenient constructor when there is no model data to expose.
而后者在解析视图时不起作用?
and yet the latter doesn't work in resolving the view?
推荐答案
忽略这两个是针对两个完全不同的环境的，不同之处在于 org.springframework.web.servlet.ModelAndView 是支持处理程序方法返回类型:
Ignoring that these two are meant for two completely different environments, the difference is that org.springframework.web.servlet.ModelAndView is a supported handler method return type:
- 一个
ModelAndView对象，该模型隐含了命令对象和@ModelAttribute注释的参考数据访问器方法的结果.
- A
ModelAndViewobject, with the model implicitly enriched with command objects and the results of@ModelAttributeannotated reference data accessor methods.
That means that Spring has a HandlerMethodReturnValueHandler implementation (ModelAndViewMethodReturnValueHandler) that will receive the return value of type ModelAndView and process it.
它没有默认注册的 org.springframework.web.portlet.ModelAndView 的实现.
It does not have such a implementation for org.springframework.web.portlet.ModelAndView registered by default.
