"Content type 'application/json;charset=UTF-8' not supported" in Spring Rest application

I also encounter this error while using following with a `PATCH` request:
```java
public Order markOrderAsPayed(@RequestBody final MultiValueMap<String, String> values) {
...
}
```
The MultiValueMap is from `org.springframework.util`. Changing the Map to `Map<String, String>` resolved the problem for me.

Sorry, but I can't give an explanation why.

may be too late for this post.

if you can add this media type in your controller class for consumes={MediaType.APPLICATION_JSON_UTF8_VALUE} you can get pass this.

Try removing charset from header Content-type, application json only, and it will probably work.

I had the same issue when using `@PutMapping` and `@RequestBody` `MultiValueMap<String,String>`. I changed the `MultiValueMap` to Map and it worked, just like what edta had suggested above.

In my case
I Had two times the same identifier for jsonProperty in my dto class
When I made the request return:
"Content type 'application/json;charset=UTF-8"
Not sure why return that error but once I changed the identifier it works.
