Is it possible to use multiple @RequestMapping annotations over a method?
Like :
@RequestMapping("/")
@RequestMapping("")
@RequestMapping("/welcome")
public String welcomeHandler(){
return "welcome";
}

@RequestMapping has a String[] value parameter, so you should be able to specify multiple values like this:
@RequestMapping(value={"", "/", "welcome"})

That said, I'm having trouble getting the "" or "/" values to actually work in my application. Do they work for you?

Is there a way to associate different success views and form views with each request URL using multiple annotations?

@EdBrannin I need many to use, custom, header, consumes, params, etc

Also I would like to know, how do I know which requestmapping has been called. is it / or welcome ?
Ed Brannin
@Siddharth 1. You might be able to add & inspect a parameter of type HttpRequest. 2. If you really care which mapping was called, maybe don't use this technique. ;)

From my test (spring 3.0.5), @RequestMapping(value={"", "/"}) - only "/" works, "" does not. However I found out this works: @RequestMapping(value={"/", " * "}), the " * " matches anything, so it will be the default handler in case no others.

Doesn't need to. RequestMapping annotation supports wildcards and ant-style paths. Also looks like you just want a default view, so you can put
<mvc:view-controller path="/" view-name="welcome"/>
in your config file. That will forward all requests to the Root to the welcome view.

Is there supposed to be something between those two lines? I am using the FreeMarkerViewResolver - so I would have to go this way... Well, I guess I could just create multiple ViewResolver.

It doesn't provide the flexibility that multiple RequestMapping annotations would provide. For example, if I want to have one method support either value "/a" with POST or value "/b" with GET. Of course the workaround is fairly easy (refactoring the functionality in a third method), but just saying that it would be useful.
The shortest way is: @RequestMapping({"", "/", "welcome"})
Although you can also do:
@RequestMapping(value={"", "/", "welcome"})@RequestMapping(path={"", "/", "welcome"})

The following is acceptable as well:
@GetMapping(path = { "/{pathVariable1}/{pathVariable1}/somePath",
"/fixedPath/{some-name}/{some-id}/fixed" },
produces = "application/json")
Same can be applied to @RequestMapping as well
Comments
It's better to use PathVariable annotation if you still want to get the uri which was called.
@PostMapping("/pub/{action:a|b|c}")
public JSONObject handlexxx(@PathVariable String action, @RequestBody String reqStr){
...
}
or parse it from request object.

Right now with using Spring-Boot 2.0.4 - { } won't work.
@RequestMapping
still has String[] as a value parameter, so declaration looks like this:
@RequestMapping(value=["/","/index","/login","/home"], method = RequestMethod.GET)
** Update - Works With Spring-Boot 2.2**
@RequestMapping(value={"/","/index","/login","/home"}, method = RequestMethod.GET)

The square brackets is invalid. The valid syntax for an array literal is to use braces {}

@luis.espinal Square brackets worked with 2.0.4 Spring-Boot version. I will update my post.
