spring整合hibernate(无hibernate.cfg.xml)

spring整合hibernate(无hibernate.cfg.xml)

因为没有hibernate.cfg.xml，把这些配置都放在了spirng的applicationContext.xml中

applicationContext.xml:

User.java:

package com.hcx.domain; public class User { /* * create table t_user( id int primary key auto_increment, username varchar(50), password varchar(32), age int ); */ private Integer id; private String username; private String password; private Integer age; User.hbm.xml:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="com.hcx.domain.User" table="t_user"> <id name="id"> <generator class="native"></generator> </id> <property name="username"></property> <property name="password"></property> <property name="age"></property> </class> </hibernate-mapping> UserDao:

package com.hcx.dao; import com.hcx.domain.User; public interface UserDao { /** * 增加一个用户 */ public void save(User usesr); } UserDaoImpl:

package com.hcx.dao.impl; import org.hibernate.validator.HibernateValidator; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; import com.hcx.dao.UserDao; import com.hcx.domain.User; public class UserDaoImpl extends HibernateDaoSupport implements UserDao { @Override public void save(User user) { this.getHibernateTemplate().save(user); } }

注意：如果是使用注解的方式，就不用通过继承HibernateDaoSupport的方式了，必须使用模版HibernateTemplate

UserService:

package com.hcx.service; import com.hcx.domain.User; public interface UserService { /** * 注册 */ public void register(User user); } UserServiceImpl:

package com.hcx.service.impl; import com.hcx.dao.UserDao; import com.hcx.domain.User; import com.hcx.service.UserService; public class UserServiceImpl implements UserService { private UserDao userDao; public void setUserDao(UserDao userDao) { this.userDao = userDao; } public void register(User user) { userDao.save(user); } } TestApp:

package com.hcx.test; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.hcx.domain.User; import com.hcx.service.UserService; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:applicationContext.xml") public class TestApp { @Autowired private UserService userService; @Test public void demo(){ User user = new User(); user.setUsername("hcx"); user.setPassword("123"); user.setAge(55); userService.register(user); } }
