SpringAop_静态代理模式

package com.spring.proxy;

public interface PersonDao {
    public void savePerson();

}



package com.spring.proxy;

public class PersonDaoImpl implements PersonDao {

    @Override
    public void savePerson() {
        
        System.out.println("save person");

    }

}




package com.spring.proxy;

public class Transaction {
    
    public void beginTransaction(){
        
        System.out.println("begin transcation");
    }
    
    public void commit(){
        
        System.out.println("commit");
    }

}


代理类
package com.spring.proxy;

public class personDaoProxy implements PersonDao {

    private PersonDao personDao;
    private Transaction transaction;
    
    
    public personDaoProxy(PersonDao personDao,Transaction transaction) {
        super();
        this.personDao = personDao;
        this.transaction=transaction;
    }


    /**
     * 由于该静态代理实现了PersonDao，所以每个方法都会执行开启事务提交事务，并没有做到事务的重用
     * 
     */
    @Override
    public void savePerson() {
        transaction.beginTransaction();
        personDao.savePerson();
        transaction.commit();
    }

}



package com.spring.proxy;

import org.junit.Test;

public class ProxyTest {
    
    @Test
    public void tsst(){
        
        PersonDao personDao=new PersonDaoImpl();
        Transaction transaction=new Transaction();
        personDaoProxy personDaoProxy=new personDaoProxy(personDao, transaction);
        personDaoProxy.savePerson();
        
    }

}
