在RequestMapping值中使用String变量 [英] Using a String variable in RequestMapping value

问题描述

我有以下内容:

@Value("${apiVersion")
private String apiVersion;

@RequestMapping(value = "/{apiVersion}/service/call", method = RequestMethod.POST)

我希望URL为:

/apiVersion/service/call

但是事实证明{foo}接受任何值，实际上并没有使用String.

But it turns out {foo} accept any value, it doesn't actually use the String.

我是否可以使用String值作为URL的一部分?

Is there a way for me to use the String value as part of the URL?

编辑

问题在于，我有多个有价值的电话.

The issue is that I have multiple calls that us that value.

@RequestMapping(value = apiVersion + "/call1", method = RequestMethod.POST)

@RequestMapping(value = apiVersion + "/call2", method = RequestMethod.POST)

@RequestMapping(value = apiVersion + "/call3", method = RequestMethod.POST)

etc.

从技术上讲，我可以像您建议的那样为每个常量声明常量，但这听起来并不理想.如果没有办法做到这一点，那很好，我只是想知道是否有.

Technically I can declare constants for each one like you suggested, but it doesn't sound optimal. If there is no way to do it then it is fine, I was just wondering if there is.

解决方案

向控制器添加常规映射.

Adding general mapping to the controller.

@RequestMapping("${apiVersion}")

推荐答案

如果要将其应用于控制器中的所有方法，请在控制器类级别上声明它:

If you want to apply it for all methods in a controller declare it on the controller class level:

@RestController
@RequestMapping("/test")
public class MyController { ...

，您无需在方法路径之前添加前缀.

and you do not need to prepend it before method path.

否则它应该是恒定的，例如:

Otherwise it should be constant so like:

private static final String FOO = "test";

并将其放在方法路径之前，如:

and prepend it before method path like:

FOO + "/service/call"
