@RequestMappinghas a String[]value parameter, so you should be able to specify multiple values like this:
@RequestMapping有一个String[]value 参数，因此您应该能够指定多个值，如下所示：
@RequestMapping(value={"", "/", "welcome"})
@RequestMapping(value={"", "/", "welcome"})

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
没必要。RequestMapping 注解支持通配符和蚂蚁风格的路径。看起来你只想要一个默认视图，所以你可以把
<mvc:view-controller path="/" view-name="welcome"/>
in your config file. That will forward all requests to the Root to the welcome view.
在您的配置文件中。这会将所有请求转发到 Root 到欢迎视图。

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.
从我的测试（spring 3.0.5）来看，@RequestMapping(value={"", "/"})- 仅"/"有效，""无效。但是我发现这有效：@RequestMapping(value={"/", " * "})，" * "匹配任何内容，因此如果没有其他处理程序，它将成为默认处理程序。

Right now with using Spring-Boot 2.0.4 - { } won't work.
现在使用 Spring-Boot 2.0.4 - { } 将不起作用。
@RequestMapping
still has String[] as a value parameter, so declaration looks like this:
仍然有 String[] 作为值参数，所以声明看起来像这样：
@RequestMapping(value=["/","/index","/login","/home"], method = RequestMethod.GET)
** Update - Works With Spring-Boot 2.2**
** 更新 - 适用于 Spring-Boot 2.2**
@RequestMapping(value={"/","/index","/login","/home"}, method = RequestMethod.GET)

It's better to use PathVariable annotation if you still want to get the uri which was called.
如果您仍然想获取被调用的 uri，最好使用 PathVariable 注释。
@PostMapping("/pub/{action:a|b|c}")
public JSONObject handlexxx(@PathVariable String action, @RequestBody String reqStr){
...
}
or parse it from request object.
或从请求对象解析它。

The shortest way is: @RequestMapping({"", "/", "welcome"})
最短的方法是： @RequestMapping({"", "/", "welcome"})
Although you can also do:
虽然你也可以这样做：
@RequestMapping(value={"", "/", "welcome"})@RequestMapping(path={"", "/", "welcome"})
@RequestMapping(value={"", "/", "welcome"})@RequestMapping(path={"", "/", "welcome"})

The following is acceptable as well:
以下也是可以接受的：
@GetMapping(path = { "/{pathVariable1}/{pathVariable1}/somePath",
"/fixedPath/{some-name}/{some-id}/fixed" },
produces = "application/json")
Same can be applied to @RequestMappingas well
同样可以应用于@RequestMapping以及
