Перенаправление регулятора пружины не работает

Я нахожусь в проекте, который использует Spring MVC 4 и Thymeleaf.Перенаправление регулятора пружины не работает

При попытке перенаправить после запроса POST с помощью:

return "redirect:/admin";

или используя:

RedirectView redirect = new RedirectView(); 
redirect.setUrl("/admin"); 
return redirect;

Я получаю NullPointerException

HTTP Status 500 - Request processing failed; nested exception is java.lang.NullPointerException 

type Exception report 

message Request processing failed; nested exception is java.lang.NullPointerException 

description The server encountered an internal error that prevented it from fulfilling this request.

Вот мой конфигурации Thymeleaf:

<!-- Thymeleaf template engine --> 
    <bean id="templateResolver" 
      class="org.thymeleaf.templateresolver.ServletContextTemplateResolver"> 
     <property name="prefix" value="/WEB-INF/templates/" /> 
     <property name="suffix" value=".html" /> 
     <property name="templateMode" value="HTML5" /> 
     <property name="cacheable" value="false" /> 
    </bean> 

    <bean id="templateEngine" 
      class="org.thymeleaf.spring4.SpringTemplateEngine"> 
     <property name="templateResolver" ref="templateResolver" /> 
     <!-- These lines add the dialect to Thymeleaf --> 
     <property name="additionalDialects"> 
      <set> 
       <bean class="nz.net.ultraq.thymeleaf.LayoutDialect"/> 
       <bean class="org.thymeleaf.extras.springsecurity3.dialect.SpringSecurityDialect" /> 
      </set> 
     </property> 

    </bean> 

    <bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver"> 
     <property name="templateEngine" ref="templateEngine" /> 
    </bean>

Любая помощь?

EDIT:

Здесь класс контроллера:

@Controller 
public class Administration { 
    @RequestMapping(value = "/admin", method = RequestMethod.GET) 
    public String index(ModelMap model) { 
     List<Market> markets = Market.findAll(Market.class); 
     model.addAttribute("markets", markets); 

     return "admin/index"; 
    } 

    @RequestMapping(value = "/admin/markets/add", method = RequestMethod.GET) 
    public String addMarket(Market market, Model model) { 
     String[] timeZones = TimeZone.getAvailableIDs(); 
     List<String> t = Arrays.asList(timeZones); 
     Arrays.sort(timeZones); 
     model.addAttribute("timeZones", t); 

     return "admin/addMarket"; 
    } 

    @RequestMapping(value = "/admin/markets/add/save", method = RequestMethod.POST) 
    public String saveMarket(@Valid Market market) { 
     market.save(); 

     return "redirect:/admin"; 
    } 
}

вы можете показать весь свой метод, от которого вы пытаетесь перенаправление? – Aeseir

Что происходит, когда вы комментируете market.save()? – Aeseir

Наверное, ничего, потому что и другие методы контроллера реагируют одинаково. –

Эта проблема была вызвана моим собственным кодом ...

@Override 
public String processUrl(HttpServletRequest httpServletRequest, String s) { 
    return null; 
}
