JspViewResolver無法在基於java配置的spring應用程序中工作

Question

我在Spring應用程序中只有基於Java的配置。我創建了用戶實體和Dao來查找/創建用戶。 控制器有兩個GET方法 - 一個用於用戶，一個用於用戶列表和一個POST方法 - 用於創建/編輯用戶。

在Tomcat 7服務器上運行後，它提供了404錯誤和消息'請求的資源不可用。

調度的servlet被配置在SpringWebAppInitializer.class：

public class SpringWebAppInitializer implements WebApplicationInitializer { 

@Override 
public void onStartup(ServletContext servletContext) throws ServletException { 

    AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext(); 
    appContext.register(ApplicationContextConfig.class); 

    servletContext.addListener(new ContextLoaderListener(appContext)); 

    AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext(); 
    dispatcherContext.register(DispatcherServlet.class); 

    ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher", new DispatcherServlet(dispatcherContext)); 
    dispatcher.setLoadOnStartup(1); 
    dispatcher.addMapping("/");  
    } 
} 

視圖解析在ApplicationContextConfig.class定義：

@Configuration 
@ComponentScan("pl.wybornie.entity") 
@EnableTransactionManagement 
public class ApplicationContextConfig extends WebMvcConfigurerAdapter { 

@Bean(name = "viewResolver") 
public InternalResourceViewResolver getViewResolver() { 

    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
    viewResolver.setPrefix("/WEB-INF/pages/"); 
    viewResolver.setSuffix(".jsp"); 
    return viewResolver; 
    } 
//other configuration beans... 
} 

的用戶列表和用戶窗體JSP文件下的WebContent項目的文件夾：/ WEB-INF/pages/user/*。jsp

負責創建視圖的控制器粘貼如下：

@Controller 
@SessionAttributes({"user"}) 
public class UserController { 

@Autowired 
private UserDao userDao; 

@RequestMapping(value = "/user_list.html", method = RequestMethod.GET) 
public String list(Model model, HttpServletRequest request) { 
    model.addAttribute("userList", userDao.usersList()); 

    return "user/userList"; 
} 

@RequestMapping(value = "/create.html", method = RequestMethod.GET) 
public String edit(@RequestParam(value="id", required=false) Long id, Model model) { 
    User user = userDao.findOrCreate(id);  
    model.addAttribute("user", user); 
    return "user/userForm"; 
} 

@RequestMapping(method = RequestMethod.POST) 
public String submitForm(@ModelAttribute("user") User user, BindingResult bindingResult, HttpServletRequest request, Model model) { 

    userDao.saveOrUpdate(user); 

    return "redirect:user_list.html"; 
} 

    public void setUserDao(UserDao userDao) { 
    this.userDao = userDao; 
    } 
}

您的類應該擴展WebMvcConfigurerAdapter類。

@Configuration 
@ComponentScan("pl.wybornie.entity") 
@EnableWebMvc 
public class ApplicationContextConfig extends WebMvcConfigurerAdapter{ 


}
