Исключение HTTP-статуса 500

Я хочу преобразовать объект в Json и вернуть его. Но я пр проблему SomИсключение HTTP-статуса 500

Мой контроллер:

@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; 
    } 
}

Я прочитал ее от this

Я попробовал это, но это не помогло.

мои еще обостря- web.xml:

<web-app version="2.4" 
    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

    <display-name>Spring MVC Application</display-name> 

    <servlet> 
     <servlet-name>mvc-dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>mvc-dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

</web-app>

это мой MVC-диспетчерская-servlet.xml:

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:context="http://www.springframework.org/schema/context"

     <property name="suffix" value=".jsp"/> 
     <mvc:annotation-driven/> 
    </bean> 
</beans>

модель пользователя. Просто POJO:

public class User { 
    private int age; 
    private String fio; 

    public int getAge() { 
     return age; 
    } 

    public void setAge(int age) { 
     this.age = age; 
    } 

    public String getFio() { 
     return fio; 
    } 

    public void setFio(String fio) { 
     this.fio = fio; 
    } 
}

если я удалить эту строку

<!--<mvc:annotation-driven/>-->

я получаю другую ошибку

HTTP Status 406 - 

type Status report 

message 

description The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers. 

Apache Tomcat/8.0.24

EDIT если я изменить:

@RequestMapping(value = "/", method = RequestMethod.GET, produces = "application/json") 
    public @ResponseBody 
    String getUser() { 
     User user = new User(); 
     user.setAge(24); 
     user.setFio("Pavel"); 
     return "sfgxdgfcg"; 
    }

я получить sfgxdgfcg в браузере

решаемые: вам нужно добавить зависимость

Попробуйте это:

    <property name="prefix" value="/WEB-INF/pages/"/> 
    <property name="suffix" value=".jsp"/>
