I have only Java-based configuration in Spring Application. I have created user entity and Dao for finding / creating users. The controller has two GET methods - one for user and one for users list and one POST method - for creating / editing a user.
After running at Tomcat 7 server it gives 404 error and message that 'The requested resource is not available.
Dispatcher servlet is configured in 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("/");
}
}
View resolver is defined in ApplicationContextConfig.class:
@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...
}
Jsp files for userList and userForm are in WebContent project's folder under: /WEB-INF/pages/user/*.jsp
Controllers responsible for geting views are pasted below:
@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;
}
}
