Spring MVC @Controller method signatures
提问by Glide
Is there an easy way to view all the possible method signature when I create a controller by annotating a class with @Controller?
当我通过用 注释一个类来创建一个控制器时，有没有一种简单的方法来查看所有可能的方法签名@Controller？
I can't find a spring documentation that lists all of that. From their guide, it seems to be reallyflexible where I don't know what I can be returning or what I could use in the method parameters.
我找不到列出所有这些的 spring 文档。从他们的指南来看，它似乎非常灵活，我不知道我可以返回什么或我可以在方法参数中使用什么。

You should check the Spring MVC reference documentationagain. In the "Defining @RequestMapping handler methods" chapter, everything is listed and explained :
您应该再次查看Spring MVC 参考文档。在“定义@RequestMapping 处理程序方法”一章中，列出并解释了所有内容：
- all the possible parameters
- all the possible return types
- all the possible method/parameter annotations, each one having its sub-chapter : @RequestParam, @RequestBody, @ResponseBody, @ModelAttribute, etc.
