Spring XML 406 error
I am trying to make a RESTful service using Java, using several tutorials and many, MANY StackOverflow entries. Unfortunately I don't seem to be able to get my code to work, I am persistantly getting Http 406 when I try and hit the endpoint. Any help is appreciated.
GreetingController.java:
import java.util.Random;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping("/greeting")
public class GreetingController {
protected final Logger log = LoggerFactory.getLogger(GreetingController.class);
private static final String template = "Hello, %s!";
private static Random rand = new Random();
@RequestMapping(method = RequestMethod.GET, headers="Accept=*/*")//, value="/{name}")
@ResponseBody
public Greeting greeting() {
log.debug("Entered greeting()");
return new Greeting(rand.nextInt(99999999),
String.format(template, "Stephen"));
}
@RequestMapping(method = RequestMethod.GET, value="/{name}")
@ResponseBody
public Greeting greetingName(@PathVariable String name) {
log.debug("Entered greetingName()");
return new Greeting(rand.nextInt(99999999),
String.format(template, name));
}
}
Greeting.java:

Answer
I just came across this when trying to troubleshoot the same issue. After looking at pfac's answer, I discovered I could solve my issue simply by adding the jackson-dataformat-xml library to my project.
If using maven:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.3.2</version>
</dependency>
