SPRING IN ACTION 第4版笔记-第五章BUILDING SPRING WEB APPLICATIONS-006-处理表单数据(注册、显示用户资料)

一、显示注册表单

1.访问资源

   @Test

   public void shouldShowRegistration() throws Exception {

     SpitterRepository mockRepository = mock(SpitterRepository.class);

     SpitterController controller = new SpitterController(mockRepository);

     MockMvc mockMvc = standaloneSetup(controller).build();

     mockMvc.perform(get("/spitter/register"))

            .andExpect(view().name("registerForm"));

   }

2.Controller

 package spittr.web;

 import static org.springframework.web.bind.annotation.RequestMethod.*;

 import javax.validation.Valid;

 import org.springframework.beans.factory.annotation.Autowired;

 import org.springframework.stereotype.Controller;

 import org.springframework.ui.Model;

 import org.springframework.validation.Errors;

 import org.springframework.web.bind.annotation.PathVariable;

 import org.springframework.web.bind.annotation.RequestMapping;

 import spittr.Spitter;

 import spittr.data.SpitterRepository;

 @Controller

 @RequestMapping("/spitter")

 public class SpitterController {

   private SpitterRepository spitterRepository;

   @Autowired

   public SpitterController(SpitterRepository spitterRepository) {

     this.spitterRepository = spitterRepository;

   }

   @RequestMapping(value="/register", method=GET)

   public String showRegistrationForm() {

     return "registerForm";

   }

   @RequestMapping(value="/register", method=POST)

   public String processRegistration(

       @Valid Spitter spitter,

       Errors errors) {

     if (errors.hasErrors()) {

       return "registerForm";

     }

     spitterRepository.save(spitter);

     return "redirect:/spitter/" + spitter.getUsername();

   }

   @RequestMapping(value="/{username}", method=GET)

   public String showSpitterProfile(@PathVariable String username, Model model) {

     Spitter spitter = spitterRepository.findByUsername(username);

     model.addAttribute(spitter);

     return "profile";

   }

 }

3.view

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

 <%@ page session="false" %>

 <html>

   <head>

     <title>Spitter</title>

     <link rel="stylesheet" type="text/css"

           href="<c:url value="/resources/style.css" />" >

   </head>

   <body>

     <h1>Register</h1>

     <form method="POST">

       First Name: <input type="text" name="firstName" /><br/>

       Last Name: <input type="text" name="lastName" /><br/>

       Email: <input type="email" name="email" /><br/>

       Username: <input type="text" name="username" /><br/>

       Password: <input type="password" name="password" /><br/>

       <input type="submit" value="Register" />

     </form>

   </body>

 </html>

二、处理注册

1.测试处理注册

 @Test

   public void shouldProcessRegistration() throws Exception {

     SpitterRepository mockRepository = mock(SpitterRepository.class);

     Spitter unsaved = new Spitter("jbauer", "24hours", "Jack", "Bauer", "jbauer@ctu.gov");

     Spitter saved = new Spitter(24L, "jbauer", "24hours", "Jack", "Bauer", "jbauer@ctu.gov");

     when(mockRepository.save(unsaved)).thenReturn(saved);

     SpitterController controller = new SpitterController(mockRepository);

     MockMvc mockMvc = standaloneSetup(controller).build();

     mockMvc.perform(post("/spitter/register")

            .param("firstName", "Jack")

            .param("lastName", "Bauer")

            .param("username", "jbauer")

            .param("password", "24hours")

            .param("email", "jbauer@ctu.gov"))

            .andExpect(redirectedUrl("/spitter/jbauer"));

     verify(mockRepository, atLeastOnce()).save(unsaved);

   }

2.Controller参考上面

3.view: return "redirect:/spitter/" + spitter.getUsername();

4.Dao

 package spittr.data;

 import java.sql.ResultSet;

 import java.sql.SQLException;

 import org.springframework.beans.factory.annotation.Autowired;

 import org.springframework.jdbc.core.JdbcOperations;

 import org.springframework.jdbc.core.RowMapper;

 import org.springframework.stereotype.Repository;

 import spittr.Spitter;

 @Repository

 public class JdbcSpitterRepository implements SpitterRepository {

   private JdbcOperations jdbc;

   @Autowired

   public JdbcSpitterRepository(JdbcOperations jdbc) {

     this.jdbc = jdbc;

   }

   public Spitter save(Spitter spitter) {

     jdbc.update(

         "insert into Spitter (username, password, first_name, last_name, email)" +

         " values (?, ?, ?, ?, ?)",

         spitter.getUsername(),

         spitter.getPassword(),

         spitter.getFirstName(),

         spitter.getLastName(),

         spitter.getEmail());

     return spitter; // TODO: Determine value for id

   }

   public Spitter findByUsername(String username) {

     return jdbc.queryForObject(

         "select id, username, null, first_name, last_name, email from Spitter where username=?",

         new SpitterRowMapper(),

         username);

   }

   private static class SpitterRowMapper implements RowMapper<Spitter> {

     public Spitter mapRow(ResultSet rs, int rowNum) throws SQLException {

       return new Spitter(

           rs.getLong("id"),

           rs.getString("username"),

           null,

           rs.getString("first_name"),

           rs.getString("last_name"),

           rs.getString("email"));

     }

   }

 }

二、显示某个用户的资料

1.测试:http://localhost:8080/SpringInAction4_Chapter5_SpringMVC01/spitter/eminem

2.controller写在上面

3.view

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

 <%@ page session="false" %>

 <html>

   <head>

     <title>Spitter</title>

     <link rel="stylesheet" type="text/css" href="<c:url value="/resources/style.css" />" >

   </head>

   <body>

     <h1>Your Profile</h1>

     <c:out value="${spitter.username}" /><br/>

     <c:out value="${spitter.firstName}" /> <c:out value="${spitter.lastName}" /><br/>

     <c:out value="${spitter.email}" />

   </body>

 </html>
