Hello,
I've used to rely on this function in older Camel, when I was able to
deserialize a regular web form POST stream into a generic java.util.Map,
I mean, this used to parse the form data (not multipart, just regular)
and convert into a Map:
Map map = http.getBody(Map.class);
This is my test code snippet that I compile and run on Java 19 of GraalVM:
```
HttpMessage http =
exchange.getIn(HttpMessage.class);
HttpServletRequest request = http.getRequest();
String method = request.getMethod();
if ("POST".equals(method) ||
"PUT".equals(method)) {
Map map = http.getBody(Map.class);
String string = http.getBody(String.class);
http.setHeader(Exchange.CONTENT_TYPE,
"text/plain");
http.setBody("json: " +
mapper.writeValueAsString(map) + ", and string:" + string);
} else {
http.setHeader(Exchange.CONTENT_TYPE,
"text/html");
http.setBody(this.getClass().getResourceAsStream("form.html"));
}
```
I've created a test project to make sure it works on Camel 2.24 and
doesn't in 3.20.4:
https://github.com/fedd/cameljettyformmap/tree/main/cameljettyformmap
I had to add `javax.activation` for the 2.24 version to run, but
unfortunately that didn't fix the 3.20.4 (See the pom.xml in the github
link)
What do I have to do to make it work in 3.20.4?
