Spring MVC3构建Web应用第五步
构建业务实体模型。在src目录中，新建包命名为paul.sydney.model，在这个包下，再新建一个实体类，命名为Person，修改代码如下：
1
package paul.sydney.model;
2
3/**
4 * Copyright : adobocode.com , 2010
5 * @author Paul Sydney Orozco | xtrycatchx@gmail.com
6 */
7public class Person {
8
9 private int id;
10 private String name;
11 private int age;
12 private String address;
13
14 public int getId() {
15 return id;
16 }
17 public void setId(int id) {
18 this.id = id;
19 }
20
21 public String getName() {
22 return name;
23 }
24 public void setName(String name) {
25 this.name = name;
26 }
27 public int getAge() {
28 return age;
29 }
30 public void setAge(int age) {
31 this.age = age;
32 }
33 public String getAddress() {
34 return address;
35 }
36 public void setAddress(String address) {
37 this.address = address;
38 }
39
40 @Override
41 public String toString(){
42 StringBuilder sb = new StringBuilder();
43 sb.append("\nname : " + this.name);
44 sb.append("\nage : " + this.age);
45 sb.append("\naddress : " + this.address);
46 return sb.toString();
47
48 }
49
50}
package paul.sydney.model; 2
3
/** 4

* @author Paul Sydney Orozco | xtrycatchx@gmail.com 6
*/7
public class Person { 8
9
private int id; 10
private String name; 11
private int age; 12
private String address; 13
14
public int getId() { 15
return id; 16
} 17
public void setId(int id) { 18
this.id = id; 19
} 20
21
public String getName() { 22
return name; 23
} 24
public void setName(String name) { 25
this.name = name; 26
} 27
public int getAge() { 28
return age; 29
} 30
public void setAge(int age) { 31
this.age = age; 32
} 33
public String getAddress() { 34
return address; 35
} 36
public void setAddress(String address) { 37
this.address = address; 38
} 39
40
@Override41
public String toString(){ 42
StringBuilder sb = new StringBuilder(); 43
sb.append("\nname : " + this.name); 44
sb.append("\nage : " + this.age); 45
sb.append("\naddress : " + this.address); 46
return sb.toString(); 47
48
} 49
50
}
构建业务逻辑层。同样在src目录下新建一个包，命名为paul.sydney.service，并且新建一个类DummyService，代码如下：
1paul.sydney.service;
2
3import java.util.ArrayList;
4
5import paul.sydney.model.Person;
6
7import java.util.List;
8
9import org.springframework.stereotype.Service;
10
11/**
12 * Copyright : adobocode.com , 2010
13 * @author Paul Sydney Orozco | xtrycatchx@gmail.com
14 */
15@Service
16public class DummyService {
17
18 /**
19 * This method supposed to be returning a Collection of Person objects from a DAO layer
20 * For this tutorial, let us just hard-code this List of Person objects
21 */
22 public List<Person> getDummyList() {
23 List<Person> list = new ArrayList<Person>();
24 Person p1 = new Person();
25 p1.setId(12345);
26 p1.setName("Paul");
27 p1.setAge(27);
28 p1.setAddress("Dalaguete, Cebu");
29
30 Person p2 = new Person();
31 p2.setId(54321);
32 p2.setName("Sydney");
33 p2.setAge(25);
34 p2.setAddress("Cebu City");
35
36 list.add(p1);
37 list.add(p2);
38 return list;
39 }
40
41 /**
42 * This method supposed to be returning Person object from a DAO layer
43 * For this tutorial, let us just hard-code the Person instance
44 */
45 public Person retrievePerson(int id) {
46 Person person = new Person();
47 person.setId(56789);
48 person.setName("Nikki");
49 person.setAge(63);
50 person.setAddress("Dalaguete, Cebu");
51 return person;
52 }
53
54 /**
55 * This method supposed to be persisting the passed Person object
56 * For this tutorial, let us include the persisting DAO layer
57 * and assume the method successful saved or updated the Person object
58 */
59 public void savePerson(Person person) {
60 System.out.println("\n\nSaving" + person);
61 }
62}
paul.sydney.service; 2
3
import java.util.ArrayList; 4
5
import paul.sydney.model.Person; 6
7
import java.util.List; 8
9
import org.springframework.stereotype.Service; 10
11
/** 12
* Copyright : adobocode.com , 2010 13
* @author Paul Sydney Orozco | xtrycatchx@gmail.com 14
*/15
@Service16
public class DummyService { 17
18
/** 19
* This method supposed to be returning a Collection of Person objects from a DAO layer 20
* For this tutorial, let us just hard-code this List of Person objects 21
*/22
public List<Person> getDummyList() { 23
List<Person> list = new ArrayList<Person>(); 24
Person p1 = new Person(); 25
p1.setId(12345); 26
p1.setName("Paul"); 27
p1.setAge(27); 28
p1.setAddress("Dalaguete, Cebu"); 29
30
Person p2 = new Person(); 31
p2.setId(54321); 32
p2.setName("Sydney"); 33
p2.setAge(25); 34
p2.setAddress("Cebu City"); 35
36
list.add(p1); 37
list.add(p2); 38
return list; 39
} 40
41
/** 42
* This method supposed to be returning Person object from a DAO layer 43
* For this tutorial, let us just hard-code the Person instance 44
*/45
public Person retrievePerson(int id) { 46
Person person = new Person(); 47
person.setId(56789); 48
person.setName("Nikki"); 49
person.setAge(63); 50
person.setAddress("Dalaguete, Cebu"); 51
return person; 52
} 53
54
/** 55
* This method supposed to be persisting the passed Person object 56
* For this tutorial, let us include the persisting DAO layer 57
* and assume the method successful saved or updated the Person object 58
*/59
public void savePerson(Person person) { 60
System.out.println("\n\nSaving" + person); 61
} 62
}
在这里，只是简单的在一个List中存放了多个person对象而已。
最后，项目的结构如下图：
接着，我们右击ant.xml，选择Run As->Ant Build,如下图：
