上篇博文中寫了spring與springmvc的整合，而這一篇則是又加上了hibernate。
與上次一樣，這一次仍然是先導入jar包，這一次則要加入hibernate中的jar包，如下圖所示：
同時再新建兩個源文件夾，一個爲config，一個爲test，分別存放配置文件與測試用例，現在來進行spring，springmvc以及hibernate的配置。
新建spring-hibernate.xml,applicationContext.xml,springmvc.xml,hibernate.cfg.xml四個配置文件，現在來對這四個配置文件進行配置。
spring-hibernate.xml:

hibernate映射文件爲：

1. <?xml version='1.0' encoding='utf-8'?>
2. <!DOCTYPE hibernate-configuration PUBLIC
3. "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

6. <session-factory>
7. <mapping resource="cn/com/domain/Users.hbm.xml"></mapping>
8. </session-factory>
9. </hibernate-configuration>
現在在web.xml中進行配置：
[html] view plain copy print?
1. <?xml version="1.0" encoding="UTF-8"?>

現在開始編程過程：
User類：
[java] view plain copy print?
1. package cn.com.domain;
2.
3. import java.io.Serializable;
4.
5. import javax.persistence.Column;
6. import javax.persistence.Entity;
7. import javax.persistence.GeneratedValue;
8. import javax.persistence.Id;
9. import javax.persistence.Table;
10.
11. import org.hibernate.annotations.GenericGenerator;
12.
13. public class Users implements Serializable {
14.
15. private String id;
16.
17. private String name;
18.
19. private String pwd;
20. public String getId() {
21. return id;
22. }
23. public void setId(String id) {
24. this.id = id;
25. }
26. public String getName() {
27. return name;
28. }
29. public void setName(String name) {
30. this.name = name;
31. }
32. public String getPwd() {
33. return pwd;
34. }
35. public void setPwd(String pwd) {
36. this.pwd = pwd;
37. }
38. }
對應的User.hbm.xml配置文件爲：
[html] view plain copy print?
1. <?xml version="1.0" encoding="utf-8"?>
2. <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
3. "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
4. <hibernate-mapping>
5. <class name="cn.com.domain.Users" table="users">
6. <id name="id" type="java.lang.String">
7. <column name="id"></column>
8. </id>
9. <property name="name" type="java.lang.String" length="20"></property>
10. <property name="pwd" type="java.lang.String" length="20"></property>
11. </class>
12. </hibernate-mapping>
IUserDao:
[java] view plain copy print?
1. package cn.com.dao;
2.
3. import cn.com.domain.Users;
4.
5. public interface IUserDao {
6.

10. }
IUserDaoImpl:
[java] view plain copy print?
1. package cn.com.dao.impl;
2.

4.
5. import cn.com.dao.IUserDao;
6. import cn.com.domain.Users;
7.
8. public class UserDaoImpl implements IUserDao {
9.
10. private HibernateTemplate hibernateTemplate;
11.
12. public HibernateTemplate getHibernateTemplate() {
13. return hibernateTemplate;
14. }
15.
16. public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
17. this.hibernateTemplate = hibernateTemplate;
18. }
19.
20. public void addUser(Users user) {
21. this.hibernateTemplate.save(user);
22. }
23.
24. public void updateUser(Users user) {
25. this.hibernateTemplate.update(user);
26. }
27.
28. }
IUserService:
[java] view plain copy print?
1. package cn.com.service;
2.
3. import cn.com.domain.Users;
4.
5. public interface IUserService {
6.
7. public void addUser(Users users);
8.
9. public void updateUser(Users user);
10. }
IUserServiceImpl:
[java] view plain copy print?
1. package cn.com.service.impl;
2.
3.
4. import cn.com.dao.IUserDao;
5. import cn.com.domain.Users;
6. import cn.com.service.IUserService;
7.
8. public class UserServiceImpl implements IUserService {
9.
10. private IUserDao userDao;
11. public void addUser(Users users) {
12. this.userDao.addUser(users);
13. }
14. public IUserDao getUserDao() {
15. return userDao;
16. }
17. public void setUserDao(IUserDao userDao) {
18. this.userDao = userDao;
19. }
20.
21. public void updateUser(Users user) {
22. this.userDao.updateUser(user);
23. }
24.
25. }
編寫的一個工具類：
ServiceProvinderCore：
[java] view plain copy print?
1. package cn.com.container;
2.
3. import org.springframework.context.ApplicationContext;
4. import org.springframework.context.support.ClassPathXmlApplicationContext;
5.
6. /**
7. * 該類的主要目的是加載spring配置文件
8. * @author Administrator
9. *
10. */
11. public class ServiceProvinderCore {
12. protected ApplicationContext context;
13.
14. public void load(String filename){
15. context=new ClassPathXmlApplicationContext(filename);
16. }
17. }
ServiceProvinder：
[java] view plain copy print?
1. package cn.com.container;
2.
3. import org.springframework.util.StringUtils;
4.
5. public class ServiceProvinder {
6. private static ServiceProvinderCore sc;
7. static{
8. sc=new ServiceProvinderCore();
9. sc.load("applicationContext.xml");
10. }
11.
12. public static Object getService(String beanName){
13. Object bean=null;
14. if(!StringUtils.hasText(beanName)){
15. throw new RuntimeException("您要訪問的服務名不能爲空！");
16. }
17. //如果spring容器中包含beanName
18. if(sc.context.containsBean(beanName)){
19. bean=sc.context.getBean(beanName);
20. }
21. //如果spring容器中不包含beanName
22. if(bean==null){
23. throw new RuntimeException("您要訪問的服務名稱["+beanName+"]不存在");
24. }
25. return bean;
26. }
27. }
控制器UserController：
[java] view plain copy print?
1. package cn.com.controller;
2.
3. import java.util.UUID;
4.
5. import org.springframework.stereotype.Controller;
6. import org.springframework.web.bind.annotation.RequestMapping;
7.
8. import cn.com.container.ServiceProvinder;
9. import cn.com.dao.IUserDao;
10. import cn.com.domain.Users;
11. import cn.com.service.IUserService;
12.
13. @Controller
14. @RequestMapping("/user")
15. public class UserController {
16.
17. @RequestMapping("/toSuccess.do")
18. public String toSuccess(){
19. System.out.println("success");
20. return "success";
21. }
22.
23. @RequestMapping("/toAdd.do")
24. public String add(){
25. return "add";
26. }
27.
28. @RequestMapping("/toLogin.do")
29. public String login(){
30. return "login";
31. }
32.
33. @RequestMapping("/toSave.do")
34. public String save(Users user){
35. System.out.println(user.getName());
36. System.out.println(user.getPwd());
37. String id=UUID.randomUUID().toString().replace("-", "").substring(0,4);
38. user.setId(id);
39. ServiceProvinder provinder=new ServiceProvinder();
40. IUserService userDao=(IUserService) provinder.getService("userService");
41. userDao.addUser(user);
42. return "success";
43. }
44. }
在這些包以及各個類的編寫中，總體結構爲：
現在來進行測試：
add.jsp
點擊提交以後：
jsp頁面轉向爲：
成功完成整合。
在這裏使用的是xml配置的文件來進行開發，如果是使用註解來做的話會更爲簡單一些。
spring+springmvc+hibernate的整合，就是這樣。
