向现有 Rest 服务添加新参数

Question

I have an existing Rest service in Java backend like such:

@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)

It is being called by JS in a GUI as such:

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

I simply need to add a new parameter "e", and have tried adding it as a new path variable:

@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)

But JS fails to call the service now. From what I can tell this should work fine. Am I missing something?

Running code on Tomcat 8.5, accessing GUI through Google Chrome version 78.0.3904.87. Following errors appear in console:

Answer 1

Probably bug in Spring, look here: https://jira.spring.io/browse/SPR-6741 It is fixed in v4.1.

Answer 2

Spring Boot was not picking up the changes to new or existing Rest controllers. Removing default package from the project, and doing a Project Build before each Publish to Tomcat has solved the issue.
