写入网址错误-> 404

Question

我正在尝试访问方法SpringBoot->

@RestController
@RequestMapping(value = { "/dv" })
.
.
.

@RequestMapping(method = RequestMethod.GET, path = "/get/{period}/{version}", produces = MediaType.APPLICATION_JSON_VALUE)
    public List<Article> getAll(
            @PathVariable("period") String period,
            @PathVariable("version") String version) {
        ...
    }

使用我的网址->

http://localhost:8080/dv/get?period=201801&version=201801_01;

但是我收到错误404，我不知道我做得不好
