javascript - 向现有 Rest 服务添加新参数

Question

我在 Java 后端有一个现有的 Rest 服务，如下所示:

@RequestMapping(value = "/service/{a}/{b}/{c}", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public Response service(@PathVariable Long a, @PathVariable String b, @PathVariable String c, @RequestBody List<String> d)

它在 GUI 中被 JS 调用，如下所示:

$http.post(
'/service/'
+ a + '/'
+ b + '/'
+ c,
d)

我只需要添加一个新参数“e”，并尝试将其添加为新的路径变量:

@RequestMapping(value = "/service/{a}/{b}/{c}/{e}", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public Response service(@PathVariable Long a, @PathVariable String b, @PathVariable String c, @PathVariable String e, @RequestBody List<String> d)

$http.post(
'/service/'
+ a + '/'
+ b + '/'
+ c + '/'
+ e,
d)

但是JS现在无法调用服务。据我所知，这应该可以正常工作。我错过了什么吗？

在 Tomcat 8.5 上运行代码，通过 Google Chrome 版本 78.0.3904.87 访问 GUI。控制台中出现以下错误:

可能是 Spring 中的错误，请看这里: https://jira.spring.io/browse/SPR-6741 在 v4.1 中已修复。
