Spring MVC POST Unsupporeted Media Type

Question

I receive 415 HTTP Unsupported Media Type error with the following code:

Spring MVC Controller:

    @RequestMapping(value="/addItem", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<String> addItem(@RequestBody final ToDoItem item) {
        toDoItemDao.create(item);
        return new ResponseEntity<String>(HttpStatus.OK);
    }

JavaScript AJAX request:

$.ajax({
    url: ToDoDemo.serverRoot + "/addItem",
    type:'POST',
    contentType: 'application/json',
    dataType:"json",
    data: JSON.stringify(oItem),
    success: function() {
    ...
    },
    error: function(jqXHR, strStatus, strErrorThrown) {
    ...
    }
});

pom.xml:

  <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-core-asl</artifactId>
        <version>1.9.8</version>
    </dependency>
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-mapper-asl</artifactId>
        <version>1.9.8</version>
    </dependency>
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-jaxrs</artifactId>
        <version>1.9.7</version>
    </dependency>

There are plenty of similar questions on StackOverflow I tried to use solutions from them, but none of the worked for me. What am I missing?

If you specify `datatype:"json"`, you don't need your `headers`. — Sotirios Delimanolis, Jan 22 '14 at 20:57
@SotiriosDelimanolis Removed headers according to your advice. — Ivan Mushketyk, Jan 22 '14 at 21:18
When you start up your application, in the logs, what request mapping is given to your handler above? — Sotirios Delimanolis, Jan 22 '14 at 21:22
Actually I was wrong about the `datatype`. Add your headers back or use the `contentType` element. Also, `datatype` should be `dataType`. — Sotirios Delimanolis, Jan 22 '14 at 21:36
I tried the demo (link on my answer bellow) with jackson 1.9.8 dependencies jackson-core-asl and jackson-mapper-asl (removing jackson-databind and jackson-core that don't exist for 1.9.8) and it works OK. Did you check if the header is scanned correctly, if the controller gets hit with the request, URL is correct? — Angular University, Jan 23 '14 at 23:14
@SotiriosDelimanolis Now it works without headers, so you were right :) — Ivan Mushketyk, Jan 24 '14 at 20:50

Have a look at this answer for a working demo of an ajax JSON POST call to a spring MVC controller, returning a JSON response (uses Spring 3.2.1.RELEASE).

With the chrome debugger tools or Firebub, make sure that the HTTP request contains:

Content-Type: application/json

These two jackson jars are needed on the classpath, see the demo pom.xml:

<dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>${jackson.version}</version>
  </dependency>

  <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
      <version>${jackson.version}</version>
  </dependency>

Make sure the @Controller is being scanned correctly, it should say if it's initialized in the logs.

They are using an older version of Jackson which is also supported. — Sotirios Delimanolis, Jan 22 '14 at 21:35

I had to add

<mvc:annotation-driven/>`

to my Spring Context. Now everything works fine.
