Question

我希望在@RequestMapping

中有两个具有通配符的端点

@RequestMapping(value="/**", method = { RequestMethod.GET}, produces = "application/json")

@RequestMapping(value="/**/versions/{versionId}", method = { RequestMethod.GET}, produces = "application/json")

当我执行应该转到/**/versions/{versionId}的请求时，即使请求应该匹配，它也优先于/**端点/**/versions/{versionId}端点。

我正在使用：

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Brixton.SR2</version>
</parent>

Answer 1

我认为您只需要更改@RequestMapping方法的顺序。

对我来说，作品http://localhost:8080/versions/1会返回version 1。

对于没有version/{versionId}的任何其他请求，它会返回index。

@Controller
public class DemoController {

    @RequestMapping(value="/**/versions/{versionId}", method = RequestMethod.GET)
    @ResponseBody
    public String version(@PathVariable String versionId){
        return "version " + versionId;
    }

    @RequestMapping(value="/**", method = RequestMethod.GET)
    @ResponseBody
    public String index(){
        return "index";
    }
}

如果您想要非常复杂的请求映射，请尝试覆盖handleRequest，因为它在此处：How to define RequestMapping prioritization 比你可以：

if (urlPath.contains("/versions")) {
    /* forward to method with @RequestMapping(value="/get/versions/{versionId}")
}

而不是：

@RequestMapping(value="/**/versions/{versionId}", method = { RequestMethod.GET}, produces = "application/json")

使用：

@RequestMapping(value="/response_for_versions/{versionId}", method = { RequestMethod.GET}, produces = "application/json")

现在所有＆＃34; ... / versions / {versionId}＆＃34;应转发给＆＃34; / response_for_versions / {versionId}＆＃34;所有其他人将由＆＃34; / **＆＃34;

使用多个通配符请求映射
