I've just started using Spring, and I'm trying to receive a form-urlencoded POST body in a rest controller, but I can't for the life of me get it to work. Here's my "Hello World"-esque controller:

```
@RestController
public class MyController {
    @ResponseBody
    @RequestMapping(
        value = "/",
        method = RequestMethod.POST,
        consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE,
        produces = MediaType.TEXT_PLAIN_VALUE
    )
    public String index(@RequestBody String text) {
        return "Text: " + text;
    }
}

```

I've tried many different variations, all with differing errors. The particular configuration above produces the following error when receiving a POST request with a "text" parameter from Postman.

```
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public java.lang.String com.mywebsite.controllers.MyController.index(java.lang.String)

```

I've looked at many other stackoverflow posts about this topic and tried to implement their various solutions to no avail. Here's a list of the most promising ones:

1. [Spring JSON request body not mapped to Java POJO](https://stackoverflow.com/questions/38960117/spring-json-request-body-not-mapped-to-java-pojo)
	* This is the ideal outcome for me, a POJO with all the parameters. However, when I tried this, all POJO fields were null no matter what I passed in.
2. [How to get Form data as a Map in Spring MVC controller?](https://stackoverflow.com/questions/24551915/how-to-get-form-data-as-a-map-in-spring-mvc-controller)
	* Following the first solution on that post, using a MultiValueMap produces the same error as above.
	* In the second, the parameter map is empty every time.
3. [How to retrieve FORM/POST Parameters in Spring Controller?](https://stackoverflow.com/questions/31594608/how-to-retrieve-form-post-parameters-in-spring-controller)
	* Produces an empty map, similar to the one above.

There were a couple more that I can no longer find, and for most of these posts I've tried tweaking the annotations each time. I had great success when I tried GET and JSON POST requests, but for some reason these urlencoded requests refuse to work.
