spring:绕过contextPath为特定的控制器 [英] spring : bypass contextPath for a specific controller

问题描述

我正在构建 Spring Cloud Config 服务器，并且使用属性server.contextPath: /configServer，但我还希望服务器对/ping(不是/configServer/ping)的任何请求响应200. 有什么方法可以绕过特定RestController的contextPath属性(或其他实现方法)?

I am building a Spring Cloud Config server and I use the property server.contextPath: /configServer but I also want my server to respond with 200 on any request to /ping (not /configServer/ping). Is there any way to bypass the contextPath property for a specific RestController (or any other way to achieve that)?

谢谢.

推荐答案

我找到了解决问题的方法:

I found the solution to my problem:

其中有一个 spring属性spring.cloud.config.server.prefix 完全符合我的要求.此前缀类似于contextPath，但仅用于配置服务器，因此我可以为/ping映射编写我的自定义控制器，而配置服务器将所有请求提供给/configServer.

There is the spring property spring.cloud.config.server.prefix which does exactly what I was looking for. This prefix is like contextPath but only for the configuration server hence I can write my custom controller for /ping mapping while configuration server serves all request to /configServer.

示例代码:

这是响应/ping的控制器

This is the controller to respond to /ping

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;    

@RestController
public class PingController {

    @RequestMapping(value = "/ping", method = RequestMethod.GET)
    public void respondToPing() {
        return;
    }

}

在应用程序属性中(我使用yml):

in the application properties (i use yml):

...
spring:
  profiles:
    active: native
  cloud:
    config:
      server:
        prefix: /api/configuration
...

我无法共享整个配置文件，但值得一提的是它不包含server.contextPath属性.

I cannot share the whole config file but it worths mentioning it doesn't include the server.contextPath property.

这将导致以下映射:
