How to use multiple @RequestMapping annotations in spring?
Is it possible to use multiple @RequestMapping
annotations over a method?
Like :
@RequestMapping("/")
@RequestMapping("")
@RequestMapping("/welcome")
public String welcomeHan开发者_JS百科dler(){
return "welcome";
}
@RequestMapping
has a String[]
value parameter, so you should be able to specify multiple values like this:
@RequestMapping(value={"", "/", "welcome"})
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.
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
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)
