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

1   @Test
2   public void shouldShowRegistration() throws Exception {
3     SpitterRepository mockRepository = mock(SpitterRepository.class);
4     SpitterController controller = new SpitterController(mockRepository);
5     MockMvc mockMvc = standaloneSetup(controller).build();
6     mockMvc.perform(get("/spitter/register"))
7            .andExpect(view().name("registerForm"));
8   }

 

2.Controller

 1 package spittr.web;
 2 
 3 import static org.springframework.web.bind.annotation.RequestMethod.*;
 4 
 5 import javax.validation.Valid;
 6 
 7 import org.springframework.beans.factory.annotation.Autowired;
 8 import org.springframework.stereotype.Controller;
 9 import org.springframework.ui.Model;
10 import org.springframework.validation.Errors;
11 import org.springframework.web.bind.annotation.PathVariable;
12 import org.springframework.web.bind.annotation.RequestMapping;
13 
14 import spittr.Spitter;
15 import spittr.data.SpitterRepository;
16 
17 @Controller
18 @RequestMapping("/spitter")
19 public class SpitterController {
20 
21   private SpitterRepository spitterRepository;
22 
23   @Autowired
24   public SpitterController(SpitterRepository spitterRepository) {
25     this.spitterRepository = spitterRepository;
26   }
27   
28   @RequestMapping(value="/register", method=GET)
29   public String showRegistrationForm() {
30     return "registerForm";
31   }
32   
33   @RequestMapping(value="/register", method=POST)
34   public String processRegistration(
35       @Valid Spitter spitter, 
36       Errors errors) {
37     if (errors.hasErrors()) {
38       return "registerForm";
39     }
40     
41     spitterRepository.save(spitter);
42     return "redirect:/spitter/" + spitter.getUsername();
43   }
44   
45   @RequestMapping(value="/{username}", method=GET)
46   public String showSpitterProfile(@PathVariable String username, Model model) {
47     Spitter spitter = spitterRepository.findByUsername(username);
48     model.addAttribute(spitter);
49     return "profile";
50   }
51   
52 }

 

3.view

 1 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
 2 <%@ page session="false" %>
 3 <html>
 4   <head>
 5     <title>Spitter</title>
 6     <link rel="stylesheet" type="text/css" 
 7           href="<c:url value="/resources/style.css" />" >
 8   </head>
 9   <body>
10     <h1>Register</h1>
11 
12     <form method="POST">
13       First Name: <input type="text" name="firstName" /><br/>
14       Last Name: <input type="text" name="lastName" /><br/>
15       Email: <input type="email" name="email" /><br/>
16       Username: <input type="text" name="username" /><br/>
17       Password: <input type="password" name="password" /><br/>
18       <input type="submit" value="Register" />
19     </form>
20   </body>
21 </html>

二、处理注册

1.测试处理注册

 1 @Test
 2   public void shouldProcessRegistration() throws Exception {
 3     SpitterRepository mockRepository = mock(SpitterRepository.class);
 4     Spitter unsaved = new Spitter("jbauer", "24hours", "Jack", "Bauer", "jbauer@ctu.gov");
 5     Spitter saved = new Spitter(24L, "jbauer", "24hours", "Jack", "Bauer", "jbauer@ctu.gov");
 6     when(mockRepository.save(unsaved)).thenReturn(saved);
 7     
 8     SpitterController controller = new SpitterController(mockRepository);
 9     MockMvc mockMvc = standaloneSetup(controller).build();
10 
11     mockMvc.perform(post("/spitter/register")
12            .param("firstName", "Jack")
13            .param("lastName", "Bauer")
14            .param("username", "jbauer")
15            .param("password", "24hours")
16            .param("email", "jbauer@ctu.gov"))
17            .andExpect(redirectedUrl("/spitter/jbauer"));
18     
19     verify(mockRepository, atLeastOnce()).save(unsaved);
20   }

2.Controller参考上面

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

4.Dao

 1 package spittr.data;
 2 
 3 import java.sql.ResultSet;
 4 import java.sql.SQLException;
 5 
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.jdbc.core.JdbcOperations;
 8 import org.springframework.jdbc.core.RowMapper;
 9 import org.springframework.stereotype.Repository;
10 
11 import spittr.Spitter;
12 
13 @Repository
14 public class JdbcSpitterRepository implements SpitterRepository {
15   
16   private JdbcOperations jdbc;
17 
18   @Autowired
19   public JdbcSpitterRepository(JdbcOperations jdbc) {
20     this.jdbc = jdbc;
21   }
22 
23   public Spitter save(Spitter spitter) {
24     jdbc.update(
25         "insert into Spitter (username, password, first_name, last_name, email)" +
26         " values (?, ?, ?, ?, ?)",
27         spitter.getUsername(),
28         spitter.getPassword(),
29         spitter.getFirstName(),
30         spitter.getLastName(),
31         spitter.getEmail());
32     return spitter; // TODO: Determine value for id
33   }
34 
35   public Spitter findByUsername(String username) {
36     return jdbc.queryForObject(
37         "select id, username, null, first_name, last_name, email from Spitter where username=?", 
38         new SpitterRowMapper(), 
39         username);
40   }
41   
42   private static class SpitterRowMapper implements RowMapper<Spitter> {
43     public Spitter mapRow(ResultSet rs, int rowNum) throws SQLException {
44       return new Spitter(
45           rs.getLong("id"),
46           rs.getString("username"),
47           null,
48           rs.getString("first_name"),
49           rs.getString("last_name"),
50           rs.getString("email"));
51     }
52   }
53 
54 }

 

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

 1 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
 2 <%@ page session="false" %>
 3 <html>
 4   <head>
 5     <title>Spitter</title>
 6     <link rel="stylesheet" type="text/css" href="<c:url value="/resources/style.css" />" >
 7   </head>
 8   <body>
 9     <h1>Your Profile</h1>
10     <c:out value="${spitter.username}" /><br/>
11     <c:out value="${spitter.firstName}" /> <c:out value="${spitter.lastName}" /><br/>
12     <c:out value="${spitter.email}" />
13   </body>
14 </html>
