名称自动代理生成器：BeanNameAutoProxyCreator
为了更好的测试，我放了俩个接口，俩个实现类：
ISomeService接口：
package cn.dawn.day18auto02; /**
* Created by Dawn on 2018/3/8.
*/
public interface ISomeService {
public void insert();
public void delete();
public void select();
public void update();
}
它的实现类:SomeServiceImpl
package cn.dawn.day18auto02; /**
* Created by Dawn on 2018/3/8.
*/
public class SomeServiceImpl implements ISomeService { public void insert() {
System.out.println("insert ok");
} public void delete() {
System.out.println("delete ok"); } public void select() {
System.out.println("select ok"); } public void update() {
System.out.println("update ok"); }
}
IBookService接口：
package cn.dawn.day18auto02; /**
* Created by Dawn on 2018/3/12.
*/
public interface IBookService {
public void selectAllBooks();
}
它的实现类：BookServiceImpl
package cn.dawn.day18auto02; /**
* Created by Dawn on 2018/3/12.
*/
public class BookServiceImpl implements IBookService {
public void selectAllBooks() {
System.out.println("selectbooks ok");
}
}
一个增强的
package cn.dawn.day18auto02; import org.springframework.aop.MethodBeforeAdvice; import java.lang.reflect.Method; /**
* Created by Dawn on 2018/3/5.
*/
/*前置增强*/
public class LoggerBefore implements MethodBeforeAdvice {
public void before(Method method, Object[] objects, Object o) throws Throwable {
System.out.println("日志记录");
}
}
xml配置文件中：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!--要增强的对象-->
<bean id="service" class="cn.dawn.day18auto02.SomeServiceImpl"></bean>
<bean id="bookservice" class="cn.dawn.day18auto02.BookServiceImpl"></bean>
<!--增强的内容-->
<bean id="myadvice" class="cn.dawn.day18auto02.LoggerBefore"></bean>
<!--顾问-->
<bean id="myadvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
<property name="advice" ref="myadvice"></property>
<!--<property name="mappedNames" value="do*"></property>-->
<!--<property name="pattern" value=".*do.*"></property>-->
<property name="patterns" value=".*e.*"></property>
</bean>
<!--名称自动代理生成器-->
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames" value="service,bookservice"></property>
<property name="interceptorNames" value="myadvisor"></property>
</bean> </beans>
此处没有顾问是不行的，名称自动代理生成器BeanNameAutoProxyCreator中的beanNames的值是String类型的数组，所以可以放多个目标对象，用逗号隔开即可
单测方法：
package cn.dawn.day18auto02; import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; /**
* Created by Dawn on 2018/3/3.
*/
public class test20180312 {
@Test
/*aop代理工厂bean异常增强*/
public void t01(){
ApplicationContext context=new ClassPathXmlApplicationContext("ApplicationContext-day18auto02.xml");
ISomeService service = (ISomeService) context.getBean("service");
IBookService bookservice = (IBookService) context.getBean("bookservice"); service.select();
bookservice.selectAllBooks(); }
}
