Hi all, I have a problem with CRUD (update / delete)

I'm confused what could be my mistake? Here and show them hibernate.cfg.xml:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> <property name="hibernate.connection.url">jdbc:postgresql://localhost/devdb</property> <property name="hibernate.connection.username">devdbuser</property> <property name="hibernate.connection.password">postgres</property> <property name="hibernate.show_sql">true</property> </session-factory> </hibernate-configuration> 

Controller:

 @Controller @SessionAttributes("users") public class HomeController { private static Logger log = LoggerFactory.getLogger(HomeController.class); @Inject private BookDAO bookDAO; @Inject @Autowired private UsersDAO usersDAO; @Autowired @Inject private UsersDAOService usersDAOService; @RequestMapping(method = RequestMethod.GET, value = {"/", "/home"}) public String showHomePage(ModelAndView mv) { log.info("Hit controller"); return "home"; } @RequestMapping(method = RequestMethod.POST, value = "/listUsers") public ModelAndView viewUsers(ModelAndView mview) { log.info("Userlarga o'tdi"); List<Users> usersList = usersDAO.getAllUserData(); return new ModelAndView("usersList", "userLIST", usersList); } @RequestMapping(method = RequestMethod.POST, value = "/regForm") public String regForm(ModelAndView mview) { log.info("Registraсiya"); return "regForm"; } @RequestMapping(method = RequestMethod.GET, value = "/listbooks") public String listBooks(Model model) { List<Book> books = bookDAO.getAllBooks(); model.addAttribute("books", books); return "listResults"; } @RequestMapping(method = RequestMethod.GET, value = "/getbook") public String getBook(String title, Model model) { List<Book> books = bookDAO.getBooksByTitle(title); model.addAttribute("books", books); return "listResults"; } @RequestMapping(method = RequestMethod.POST, value = "/upload") public String uploadFile(String description, @RequestParam(value = "myFile") MultipartFile uploadedFile, Model model) { Long fileSize = uploadedFile.getSize(); log.info("File size received = " + fileSize); log.info("Description = " + description); model.addAttribute("desc", description); model.addAttribute("fileSize", fileSize); return "uploadSuccess"; } @RequestMapping(method = RequestMethod.POST, value = "/addUser") public String addUser(@ModelAttribute("userAdded") Users users, ModelMap modelMap) { // ModelAndView modelMap.addAttribute("userName", users.getUserName()); modelMap.addAttribute("userFam", users.getUserFam()); modelMap.addAttribute("userLogin", users.getUserLogin()); modelMap.addAttribute("userPass", users.getUserPass()); modelMap.addAttribute("userEmail", users.getUserEmail()); modelMap.addAttribute("userAge", users.getUserAge()); if (users.getUserName() != null && users.getUserAge() > 7 && users.getUserEmail() != null && users.getUserFam() != null && users.getUserLogin() != null && users.getUserPass() != null) { usersDAOService.insertUser(users); } else { System.out.println("Qatorlarni to'liq to'ldiring!"); return "regForm"; } return "success"; } @RequestMapping(value = "/delete/{userId}", method = RequestMethod.POST) public ModelAndView deleteUser(@PathVariable(value="userId") Integer userId, Users users ) throws NotFoundException{ //Integer userid ModelAndView modelAndView = new ModelAndView("usersList"); try { usersDAOService.delUser(userId); String delMessage = "User by id number is " + usersDAOService.getUsersById(users.getUserId()) + " was succesfully removed"; modelAndView.addObject("message", delMessage); return modelAndView; } catch (Exception e) { e.printStackTrace(); System.out.println("This user is does not deleted, try later!"); return new ModelAndView("usersList"); } } @RequestMapping(method = RequestMethod.PUT, value = "/update/{userid}") //method = RequestMethod.PUT, value = public String updateUser(@ModelAttribute Users users) { usersDAOService.updateUser(users); return "usersList"; } @RequestMapping(method = RequestMethod.POST, value = "/edit/{userid}") public String editUser(@RequestParam(value = "userid", required = true) Integer id, @ModelAttribute Users users, ModelMap modelMap) { if (true) { Users usersObject = usersDAOService.getUsersById(id); return "Edit" + usersObject; } else { return "usersList"; } } } 

And my user list:

 <div class="orta"> <table class="tabList2" border="1px"> <tr> <td>Id</td> <td>Login</td> <td>Password</td> <td>User name</td> <td>Last name</td> <td>Email</td> <td>Age</td> <td>Update</td> <td>Delete</td> </tr> <c:if test="${!empty userLIST}"> <c:forEach var="users" items="${userLIST}"> <tr> <td><c:out value="${users.userId}"/></td> <td><c:out value="${users.userLogin}"/></td> <td><c:out value="${users.userPass}"/></td> <td><c:out value="${users.userName}"/></td> <td><c:out value="${users.userFam}"/></td> <td><c:out value="${users.userEmail}"/></td> <td><c:out value="${users.userAge}"/></td> <td> <form method="post" action="/edit"> <input type="submit" class="update_Delete" value="Update"/> </form> </td> <td> <form name="userId" action="/delete/?id=${users.userId}" method="POST" target="_blank"> <input type="submit" class="update_Delete" value="DELETE" /> </form> </td> </tr> </c:forEach> </c:if> </table> </div> 

servlet-context.xml:

 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd" default-autowire="byName"> <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure --> <!-- Enables the Spring MVC @Controller programming model --> <mvc:annotation-driven /> <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory --> <mvc:resources mapping="/resources/**" location="/resources/" /> <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> </bean> <!-- Enables proper handling of multipart post requests such as file uploads --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="10000000" /> </bean> <!-- Enable rendering of JSON back to client --> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="mediaTypes"> <map> <entry key="json" value="application/json" /> <entry key="xml" value="text/xml" /> <entry key="htm" value="text/html" /> </map> </property> <property name="favorParameter" value="true" /> <property name="favorPathExtension" value="false" /> <property name="ignoreAcceptHeader" value="true" /> <property name="defaultContentType" value="application/json" /> </bean> <context:component-scan base-package="com.force.samples" /> <!-- Persistence infrastructure --> <tx:annotation-driven /> <!-- Drives transactions using local JPA APIs --> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="exampleHibernateJPA" /> </bean> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <!-- DAO configs --> <bean id="usersDAO" class="com.force.samples.dao.UsersDAOImpl" /> <bean id="usersDAOService" class="com.force.samples.dao.UsersDAOServiceImpl" /> </beans> 

Gives an error

HTTP Status 404 - type.

and on the idea like this:

WARN: org.springframework.web.servlet.PageNotFound | No mapping found for HTTP request with URI [/ edit] in DispatcherServlet with name 'appServlet'

or

WARN: org.springframework.web.servlet.PageNotFound | No mapping found for HTTP request with URI [/ delete /] in DispatcherServlet with name 'appServlet'

Thank you all in advance for your attention!
