Multiple Spring @RequestMapping annotations

问题:

Is it possible to use multiple @RequestMapping spring annotations in a method? Like:

@RequestMapping("/")
@RequestMapping("")
@RequestMapping("/welcome")
public String welcomeHandler(){
 return("welcome");
}

回答1:

@RequestMapping has a String[] value parameter, so you should be able to specify multiple values like this:

@RequestMapping(value={"", "/", "welcome"})

回答2:

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.

回答3:

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.

Right now with using Spring-Boot - { } won't work.

@RequestMapping

still has String[] as a value parameter, so declaration looks like this:

 @RequestMapping(value=["/","/index","/login","/home"], method = RequestMethod.GET)
