Spring中的注解和注入

本帖最后由冯超于 2014-4-29 12:30 编辑

学过Spring的同学都知道，Spring核心两大模块一个是AOP，另外一个是控制翻转。Spring中的配置文件：

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

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">

</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${JDBC.DBDriver}"></property>
<property name="jdbcUrl" value="${JDBC.Connection}"></property>
<property name="user" value="${JDBC.User}"></property>
<property name="password" value="${JDBC.Password}"></property>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configLocation="classpath:hibernate.cfg.xml"
/>
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="save*" propagation="REQUIRED" isolation="DEFAULT"/>
<tx:method name="delete*" propagation="REQUIRED" isolation="DEFAULT"/>
<tx:method name="update*" propagation="REQUIRED" isolation="DEFAULT"/>

</tx:advice>
<aop:config>
<aop:pointcut id="txPointcut" expression="execution(* com.feng.service.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
</aop:config>
</beans>

复制代码

详细说在bean.xml进行诸如：

      <bean id="userService" class="com.feng.service.UserService">
         
         <property name="userDao" ref="UserDao"></property>
      </bean>

==userService = new UserService();  属性userDao也被实例化
==

package com.feng.service.imp;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.feng.dao.BaseDao;
import com.feng.model.User;
import com.feng.service.UserService;
/**
*
* @author fengchao
*
*/
//像Spring容器中注入UserServiceImp 类
@Service("userService")
public class UserServiceImp extends BaseServiceImp<User> implements UserService{
@Resource(name="userDao")
public void setBaseDao(BaseDao<User> dao) {
// TODO Auto-generated method stub
super.setBaseDao(dao);
}
}

复制代码

<bean id="UserDao" class="com.feng.dao.imp.UserDaoHibernateImp"></bean>
==UserDao = new UserDaoHibernateImp();==

package com.feng.dao.imp;
import org.springframework.stereotype.Repository;
import com.feng.model.User;
/**
*
* @author fengchao
*
* @param <User>
*/
//像Spring中注入 UserDaoImp类
@Repository("userDao")
public class UserDaoImp extends BaseDaoImp<User> {
}

复制代码

构造函数的就不说le ！！！
