I am working on a basic Hello World program using Spring and Restful webservices. But when I try to call my service I am getting below error message:
HTTP Status 406 -
description - The resource identified by this request is only capable
of generating responses with characteristics not acceptable according
to the request "accept" headers.
Here is my web.xml file's servlet mapping:
<servlet>

Here is my controller:
package hello;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
#RequestMapping("/greeting")
public Greeting greeting(#RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(),
String.format(template, name));
}
}
This is my Greeting pojo class:
package hello;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
When I deploy my application and access the URL as http://localhost:8081/WebServices1/rest/greeting, I am getting HTTP 406 error message in browser.

The issue is with the dependencies that you have in pom.xml file.
In Spring 4.1.* version the pom.xml dependency for Jackson libraries should include these:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.4.1</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.4.1.1</version>
</dependency>
You can get more details in these posts:
Spring JSON request getting 406 (not Acceptable) - Answer given by bekur
and also here:
406 Spring MVC Json, not acceptable according to the request "accept" headers
Also FYI, your code will work if you change the spring version back to 4.0.* or anything else.

The request mapping that you've defined in your Controller class is:
#RequestMapping(value = "/firstapp_spring/greeting", method = RequestMethod.GET)
and the URL you're trying to access is:
http://localhost:8080/myproject/greeting
You're missing the "/firstapp_spring" part.
Since you're using Spring > 4.3 you can take advantage of the new HTTP mapping annotations: #GetMapping and #PostMapping
Your request mapping can become, the much shorter equivalent:
#GetMapping("/firstapp_spring/greeting")
Following a spring mvc tutorial and I am getting the error
HTTP Status [404] – [Not Found]
The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Can anyone identify whats missing or can point me in the right direction?

you need to use #RequestMapping("/homeController") after #Controller for mapping of Controller. and use #RequestMapping(value = "/hello", method = RequestMethod.GET) before method.
and url will b : http://localhost:8080/project-name/homeController/hello and use GET method.
I've been fighting with the Spring framework for few weeks now, and I got
a normal MVC page to show up, and I got JDBC to print onto the console.
But I can't seem to get these to work together...
I've been through countless tutorials at this point and every one of them
seem to have some type of error or problem.
I think I've finally managed to get together a pretty decent and working build, but nope, still getting only 404's.
I think the problem might be in the spring-servlet.xml file:
<context:component-scan base-package="src" />
And I'm not sure if you can even load project like that, but it's the only thing I can think of here.
I include all the other files too, though.

Project tree
Project tree from Eclipse Neon2
Not my answer but the one which solved the case, posting as answers since it's buried deep in comments.
Sorry for the delay.... It still not right. I know that because
Eclipse should not show the package as main.java.controller.... Maven
ignores that folder and start right under the java folder as it was
the src folder itself. Something must be wrong on your project. Try
cleaning everything, remove the project from eclipse, delete
(physically) the folder .settings and the file .classpath and the file
.project. Go on your folder project on the console and run mvn clean
eclipse:clean then open all folders of if (like the image I showed to
you) and paste it here so I can see what it is wrong
– Jorge Campos
I created a Java Spring MVC web app which offers simple restful services.
And I have the object class like this..
public class CreateEventWrapper {
private String Topic;
private String SubscriptionReference;
private Date UtcTime;
private List<Message> Messages;
...
}
public class Message {
private List<Source> Source;
...
}
public class Source {
private String Name;
private String Value;
...
}
The controller:
...
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller
#RequestMapping(produces = "application/json")
class EventController {
#RequestMapping(value = "/event", method = RequestMethod.POST)
public ResponseEntity<CreateEventWrapper> CreateEvent(#RequestBody CreateEventWrapper eventWrapper) {
return new ResponseEntity<CreateEventWrapper>(eventWrapper, HttpStatus.OK);
}
}
And I have the json format file using Postman to upload to the server.
The upload function works fine.
{
"topic":"Face",
"subscriptionReference":"http:\\abc",
"utcTime":"2016-10-20T19:00:00Z",
"messages":[{
"source":[{"name":"VideoSource","value":"[1]123.avi"},
{"name":"AnalyticEngine","value":"FacialRecognition"}]
}]
}
I expect the format will be the same with the object order in the class
something like topic, subscriptionReference, utcTime, orderm, message..
but I got the output with message, subscriptionReference, utcTime, topic..
{
"messages": [
{
"source": [
{
"name": "VideoSource",
"value": "[1]123.avi"
},
{
"name": "AnalyticEngine",
"value": "FacialRecognition"
}
]
}
],
"subscriptionReference": "http:\abc",
"utcTime": 1476990000000,
"topic": "Face"
}
Can I have the specific order just like the class object order?
Attach with my spring config and porm.xml for reference.

You shall try this
//lower cases since it affects the json output not the class field names
#JsonPropertyOrder({ "topic", "subscriptionReference", "utcTime", "messages" })
public class CreateEventWrapper {
private String Topic;
private String SubscriptionReference;
private Date UtcTime;
private List<Message> Messages;
...
}
And I suggest you to use lowerCamelCase naming variables convention in your code since its most popular
I want convert Object to Json and return it. But i ave som problem
My controller:
#Controller
#RequestMapping("/")
public class HelloController {
#RequestMapping(value = "/", method = RequestMethod.GET, produces = "application/json")
public #ResponseBody User getUser() {
User user = new User();
user.setAge(24);
user.setFio("Pavel");
return user;
}
}
I read it from this
I tried it but it not helped.
