spring 之 ssh整合
struts2，spring，hibernate整合步骤如下：
- 新建web项目
- 导入jar包
antlr-2.7.7.jar aopalliance.jar asm-3.3.jar asm-commons-3.3.jar asm-tree-3.3.jar aspectjweaver.jar c3p0-0.9.2.1.jar commons-fileupload-1.2.2.jar commons-io-2.0.1.jar commons-lang3-3.1.jar commons-logging.jar dom4j-1.6.1.jar freemarker-2.3.19.jar hibernate-c3p0-4.3.10.Final.jar hibernate-commons-annotations-4.0.5.Final.jar hibernate-core-4.3.10.Final.jar hibernate-jpa-2.1-api-1.0.0.Final.jar jandex-1.1.0.Final.jar javassist-3.18.1-GA.jar jboss-logging-3.1.3.GA.jar jboss-logging-annotations-1.2.0.Beta1.jar jboss-transaction-api_1.2_spec-1.0.0.Final.jar mchange-commons-java-0.2.3.4.jar mysql-connector-java-5.1.20-bin.jar ognl-3.0.5.jar spring-aop-4.1.6.RELEASE.jar spring-aspects-4.1.6.RELEASE.jar spring-beans-4.1.6.RELEASE.jar spring-context-4.1.6.RELEASE.jar spring-core-4.1.6.RELEASE.jar spring-expression-4.1.6.RELEASE.jar spring-jdbc-4.1.6.RELEASE.jar spring-orm-4.1.6.RELEASE.jar spring-tx-4.1.6.RELEASE.jar spring-web-4.1.6.RELEASE.jar spring-webmvc-4.1.6.RELEASE.jar struts2-core-2.3.4.jar struts2-spring-plugin-2.3.4.jar xwork-core-2.3.4.jar
- 新建vo类：
@Entity @Table(name="t_user") public class User implements Serializable{ @Id @GeneratedValue(strategy=GenerationType.AUTO) private int id; private String name; private int age; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
- 新建dao类：
public class UserDaoImpl implements UserDao{ private SessionFactory sessionFactory; public List<User> findAll() { return sessionFactory.getCurrentSession().createQuery("from User").list(); } public int save(User user) { try { sessionFactory.getCurrentSession().save(user); return 1; } catch (HibernateException e) { e.printStackTrace(); } return -1; } public int delete(User user) { try { sessionFactory.getCurrentSession().delete(user); return 1; } catch (HibernateException e) { e.printStackTrace(); } return -1; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } }
- 新建service类：
public class UserServiceImpl implements UserService { private UserDao userDao; public List<User> findAll() { return userDao.findAll(); } public int save(User user) { return userDao.save(user); } public void setUserDao(UserDao userDao) { this.userDao = userDao; } }
- 新建action类：
public class UserAction { private List<User> list; private UserService userService; public String list(){ list = userService.findAll(); return Action.SUCCESS; } public List<User> getList() { return list; } public void setList(List<User> list) { this.list = list; } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } }
- 配置spring的配置文件：ApplicationContext-core.xml

- 配置applicationContext-asd.xml

- 配置struts配置文件
<package name="default" namespace="/" extends="struts-default"> <action name="list" class="userAction" method="list"> <result>/list.jsp</result> </action> </package>
- 配置web.xml
