spring-aop(二)

用maven配置項目

一：配置文件：

pom.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

src/main/resources/beans.xml文件：

<?xml version="1.0" encoding="utf-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!--aop註解支持-->

    <!--容器bean註解支持-->
    <context:annotation-config/>
    <context:component-scan base-package="com.zit.entity,com.zit.dao"/>


</beans>

實體類文件：

src/main/java/com.zit.dao.BookDao.java   Log.java  Student.Dao

package com.zit.dao;

import lombok.Data;
import org.springframework.stereotype.Service;

@Data
@Service("bdao")
public class BookDao {
    public void add() {
        System.out.println("添加數據");
    }

    public void bsaveb() {
        System.out.println("保存數據");
    }

    public void saveBook() {
        System.out.println("保存書籍信息");
    }
}



package com.zit.dao;

import lombok.Data;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Service;

@Data
@Service
@Aspect
public class Log {
    @Before("execution(public * com.zit.dao..*.*(..))")
    public void connect() {
        System.out.println("連接數據庫....");
    }

    @After("execution(public * com.zit.dao..*.*save*(..))")
    public void close() {
        System.out.println("關閉數據庫連接...");
    }

}


package com.zit.dao;

import lombok.Data;
import org.springframework.stereotype.Service;

@Data
@Service("sdao")
public class StudentDao {
    public void save() {
        System.out.println("保存學生信息...");
    }
}

測試類：

src/test/java/com/Demo.java

package com;

import com.zit.dao.BookDao;
import com.zit.dao.StudentDao;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Demo {
    @Test
    public void ab() {
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");

        /*for(String key:ctx.getBeanDefinitionNames()){
            System.out.println(key);
        }*/
   /*     StudentDao sdao=ctx.getBean("sdao",StudentDao.class);
       sdao.save();*/
        BookDao bdao = ctx.getBean("bdao", BookDao.class);
        bdao.add();
        bdao.bsaveb();
        bdao.saveBook();
    }
