Fyodor Kravchenko created CAMEL-19500:
-----------------------------------------
Summary: HttpMessage#getBody(Map.class) doesn't parse the regular
web form POST
Key: CAMEL-19500
URL: https://issues.apache.org/jira/browse/CAMEL-19500
Project: Camel
Issue Type: Bug
Components: camel-jetty, core
Affects Versions: 3.20.4
Environment: $ lsb_release -d
Description: Ubuntu 22.04.2 LTS
$ java --version
openjdk 19.0.1 2022-10-18
OpenJDK Runtime Environment GraalVM CE 22.3.0 (build 19.0.1+10-jvmci-22.3-b08)
OpenJDK 64-Bit Server VM GraalVM CE 22.3.0 (build 19.0.1+10-jvmci-22.3-b08,
mixed mode, sharing)
Reporter: Fyodor Kravchenko
Fix For: 3.x
In Camel 2, when the form was submitted, the payload was able to be presented
as a {{java.util.Map}} like this:
{code:java}
Map map = httpMessage.getBody(Map.class);{code}
In Camel 3.20.4 this doesn't work.
I've created a [little github
project|https://github.com/fedd/cameljettyformmap/tree/main/cameljettyformmap]
to demonstrate and reproduce the error. In the project's
[{{pom.xml}}|https://github.com/fedd/cameljettyformmap/blob/main/cameljettyformmap/pom.xml]
file you can easily switch the Camel versions to see how version 2.24.0
behaves as expected in a true Camel manner, and 3.20.4 does not.
In essence, the code to check the behavior is like below. {{form.html}} is a
simplest POST web form.
{code:java}
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"));
}
{code}
It should print the jsonified form POST payload, but doesn't for the Camel 3.
