I'm using templateRest to post User object to Rest Server but I encoutered the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonProcessingException at edu.java.spring.service.client.RestClientTest.main(RestClientTest.java:33) Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonProcessingException at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 1 more
Here is the file RestClientTest.java
public class RestClientTest {
public static void main(String[] args) throws IOException{
RestTemplate rt = new RestTemplate();
// System.out.println("Rest Response" + loadUser("quypham"));
// URL url = new URL("http://localhost:8080/rest/user/create");
rt.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
rt.getMessageConverters().add(new StringHttpMessageConverter());
// Map<String,String> vars = new HashMap<String,String>();
User user = new User();
user.setUserName("datpham");
user.setPassWord("12345");
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR,1960);
user.setBirthDay(calendar.getTime());
user.setAge(12);
String uri = new String("http://localhost:8080/rest/user/create");
User returns = rt.postForObject(uri, user,User.class);
// createUser(user);
System.out.println("Rest Response" + loadUser("datpham"));
}
Here is the file UserRestServiceController.java
@Controller
public class UserRestServiceController {
@Autowired
public UserDao userDao;
@RequestMapping(value = "/rest/user/create",method = RequestMethod.POST)
@ResponseStatus(HttpStatus.CREATED)
public void addUser(@RequestBody User user){
userDao.save(user);
}

I have browsed information on google, afterwards I have tried to add jackson 2.4 in pom.xml but didn't seem to work:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.4.0-rc3</version>
</dependency>
