<!--注入业务-->

<!--将增强和业务织入到一起-->
<property name="target" ref="idoSomeServiceimpl"></property>
<!--拦截器-->
<property name="interceptorNames" value="qianzeng"></property>
</bean>
</beans>
步骤四：
public static void main(String[] args) {
ApplicationContext atc=new ClassPathXmlApplicationContext("applicationContext.xml");
IdoSomeService proxyFactory = (IdoSomeService)atc.getBean("proxyFactory");
proxyFactory.Some();
}
创建一个接口
public interface IdoSomeService {
public void Some();
}
让业务类继承这个接口
public class IdoSomeServiceimpl implements IdoSomeService {
@Override
public void Some() {
System.out.println("真实业务代码");
}
}
修改大配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<!--拦截器-->
<property name="interceptorNames" value="qianzeng"></property>
<!--设置动态代理-->
<property name="proxyTargetClass" value="true"></property>
</bean>
</beans>
步骤一：
public interface IdoSomeService {
public void Some();
}
步骤二：
public class IdoSomeServiceimpl implements IdoSomeService {
@Override
public void Some() {
System.out.println("真实业务代码");
}
}
步骤三：
public class MyAroundAdvice implements MethodInterceptor {
@Override
public Object invoke(MethodInvocation invocation) throws Throwable {
System.out.println("环绕前");
Object proceed = invocation.proceed();
Object aThis = invocation.getThis();
System.out.println(aThis);
System.out.println("环绕后");
return proceed;
}
}
步骤四：

步骤五：
@Test
public void proxy(){
ApplicationContext atc=new ClassPathXmlApplicationContext("applicationContext.xml");
IdoSomeService proxyFactory = (IdoSomeService)atc.getBean("proxyFactoryBean");
proxyFactory.Some();
}
步骤一：
public interface IdoSomeYichang {
public void Some();
}
步骤二：（这里写了个异常）
public class IdoSomeYichangimpl implements IdoSomeYichang{
@Override
public void Some() {
int sum=5/0;
System.out.println("真实业务代码");
}
}
步骤三：
public class Yichangimpl implements ThrowsAdvice {
public void afterThrowing(Exception e){
System.out.println("发生了异常，执行增强操作");
}
}
步骤四：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

</beans>
第五步：
@Test
public void proxys(){
ApplicationContext atc=new ClassPathXmlApplicationContext("applicationContext.xml");
IdoSomeYichang proxyFactory = (IdoSomeYichang)atc.getBean("proxyFactoryBean");
proxyFactory.Some();
}
