32 <property name="prefix" value="/WEB-INF/"/>
33 <property name="suffix" value=".jsp"/>
34 </bean>
35 </beans>
3、domain类
1 package com.xiaostudy.domain;
2
3 public class User {
4
5 private int id;
6 private String username;
7 private String password;
8 private int age;
9
10 public int getId() {
11 return id;
12 }
13
14 public void setId(int id) {
15 this.id = id;
16 }
17
18 public String getUsername() {
19 return username;
20 }
21
22 public void setUsername(String username) {
23 this.username = username;
24 }
25
26 public String getPassword() {
27 return password;
28 }
29
30 public void setPassword(String password) {
31 this.password = password;
32 }
33
34 public int getAge() {
35 return age;
36 }
37
38 public void setAge(int age) {
39 this.age = age;
40 }
41
42 @Override
43 public String toString() {
44 return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]";
45 }
46
47 }
4、封装domain类
1 package com.xiaostudy.controller;
2
3 import com.xiaostudy.domain.User;
4
5 public class CustomUser {
6
7 private User user;
8
9 public User getUser() {
10 return user;
11 }
12
13 public void setUser(User user) {
14 this.user = user;
15 }
16
17 @Override
18 public String toString() {
19 return "CustomUser [user=" + user + "]";
20 }
21
22 }
5、注解类
1 package com.xiaostudy.controller;
2
3 import org.springframework.stereotype.Controller;
4 import org.springframework.web.bind.annotation.RequestMapping;
5 import org.springframework.web.bind.annotation.RequestMethod;
6
7 import com.xiaostudy.domain.User;
8
9 @Controller//<bean class="com.xiaostudy.controller.MyController"/>
10 @RequestMapping(value="/myController")//访问该类的方法时，前面多这样一个路径
11 public class MyController {
12
13 // @RequestMapping("hello")//http://localhost:8080/demo2/hello.do
14 // @RequestMapping("/hello")//http://localhost:8080/demo2/hello.do
15 // @RequestMapping(value="/hello.do")//http://localhost:8080/demo2/hello.do
16 // @RequestMapping(value="/hello.do",method=RequestMethod.GET)//http://localhost:8080/demo2/hello.do
17 // @RequestMapping(value="/hello.do",method= {RequestMethod.GET,RequestMethod.POST})//http://localhost:8080/demo2/hello.do
18 public String print() {
19 return "index";
20 }
21
22 @RequestMapping("hi")//http://localhost:8080/demo2/myController/hi.do
23 public String hello() {
24 return "index";
25 }
26
27 @RequestMapping("requestint")//http://localhost:8080/demo2/myController/requestint.do
28 public String requestint(int id) {
29 System.out.println(id);
30 return "index";
31 }
32
33 @RequestMapping("requestint2")//http://localhost:8080/demo2/myController/requestint2.do
34 public String requestint2(int id, int i) {
35 System.out.println(id + " " + i);
36 return "index";
37 }
38
39 @RequestMapping("requestint3")//http://localhost:8080/demo2/myController/requestint3.do
40 public String requestint3(User user) {
41 System.out.println(user);
42 return "index";
43 }
44
45 @RequestMapping("requestint4")//http://localhost:8080/demo2/myController/requestint4.do
46 public String requestint4(CustomUser customUser) {
47 System.out.println(customUser);
48 return "index";
49 }
50
51 @RequestMapping("xiaostudy")//http://localhost:8080/demo2/myController/hi.do
52 public String add() {
53 return "xiaostudy";
54 }
55
56 }
6、填写表单数据的xiaostudy.jsp
