Spring中的异常增强

接口：
/**
 * 接口
 * Created by Administrator on 2017/10/7.
 */
public interface ISomeService {
    public void SomeService() throws Exception;
}

实现类：

/**
 * 接口的实现类
 * Created by Administrator on 2017/10/7.
 */
public class SomeService implements ISomeService {
    //核心业务 异常增强
    public  void SomeService() throws Exception{
        int result=5/0;
        System.out.println("hello");
    }
}

异常通知
/**
 * 
 * Created by Administrator on 2017/10/12.
 */
public class MyExceptionAdvisor implements ThrowsAdvice {
    public void afterThrowing(Exception ex){
        System.out.println("错误");
    }
}

xml配置文件：

<beans xmlns="http://www.springframework.org/schema/beans"

测试类：

/**
 * 异常增强
 */
@Test
public void Test(){
    ApplicationContext context=new ClassPathXmlApplicationContext("applicationContextExceptionAdvice.xml");
    ISomeService someService=(ISomeService)context.getBean("proxyService");
    try {
        someService.SomeService();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

结果：
