SSH2搭建篇04——配置spring注解

感觉使用spring注解相当方便，就对原来的项目做了下改变，主要是对spring配置文件的改变

1：applicationContext-hibernate.xml

2：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"  
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">  

	<!-- Hibernate configuration -->
	<import resource="classpath:applicationContext-hibernate.xml" />

	 <!-- 采用注释的方式配置bean -->  
    <context:annotation-config />  
    <context:component-scan base-package="com.yeshun" />

    <!-- 配置一个事务切面 -->  
    <aop:config>  
        <aop:pointcut expression="execution(* com.yeshun.service.impl.*Impl.*(..))"   
            id="txManager" />  
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txManager" />  
    </aop:config>  
  
    <!-- 配置事务的具体使用方式 -->  
    <tx:advice id="txAdvice" transaction-manager="transactionManager">

            <tx:method name="add*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>
        <!-- 其他方法使用默认的事务设置 -->
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes> 
    </tx:advice> 
	
	
	
</beans>  

还有就是BaseDaoImpl 有了些改变

package com.yeshun.dao.impl;

import java.io.Serializable;
import java.sql.SQLException;
import java.util.List;

import javax.annotation.Resource;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.yeshun.dao.BaseDao;

/**
 * @author yeshun
 */
public class BaseDaoImpl extends HibernateDaoSupport implements BaseDao {
	protected @Resource(name = "jdbcTemplate") 
		JdbcTemplate jdbcTemplate;

	@Resource(name = "hibernateTemplate")
	public void setSupperHibernateTemplate(HibernateTemplate hibernateTemplate) {
		super.setHibernateTemplate(hibernateTemplate);
	}
	

	public Object getObject(Class clazz, Serializable id) {
		return getHibernateTemplate().load(clazz.getName(), id);
	}

	public Object saveObject(Object obj) throws RuntimeException, SQLException{
		return getHibernateTemplate().save(obj);
	}

	public void updateObject(Object obj) throws RuntimeException, SQLException{
		getHibernateTemplate().update(obj);
	}
	
    public void saveOrUpdate(Object obj) throws RuntimeException, SQLException{
    	getHibernateTemplate().saveOrUpdate(obj);
	}


	public void deleteObject(Object obj) throws RuntimeException, SQLException{
		this.getHibernateTemplate().delete(obj);
	}
	public Object removeObject(Class clazz, Serializable id) throws RuntimeException, SQLException{
		// TODO Auto-generated method stub
		Object obj = this.getObject(clazz, id);
		if(obj!=null)deleteObject(obj);
		return obj;
	}

	public java.util.List getAll(Class clazz) {
		List list=getHibernateTemplate().loadAll(clazz);
		return list;
	}
	
}

别的，基本是在DaoImpl 的类上面加上@Repository("UserDaoImpl")  （UserDaoImpl 相当于spring  bean的名字）

package com.yeshun.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.yeshun.bean.User;
import com.yeshun.dao.UserDao;
import com.yeshun.service.UserService;

@Transactional
@Service("UserServiceImpl")
public class UserServiceImpl implements UserService{

	private @Resource(name = "UserDaoImpl")
		UserDao userDao;

	public List<User> findAllUser() {
		// TODO Auto-generated method stub
		return userDao.findAllUser();
	}

}
