2).在配置文件中加入aop的命名空间
3).基于注解的方式
1.在配置文件中加入如下配置:
<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
2.把横切关注点的代码抽象到切面的类中
- 切面首先是一个IOC中的bean,即加入@Component注解
- 切面还需要加入@Aspect注解
3.在类中声明各种通知:
- 声明一个方法
- 在方法前加入@Before注解
4.可以再通知方法中声明一个类型为JoinPoint的参数,然后就能访问链接细节,如方法名称和参数值
代码:

//加减乘除的接口类
public interface ArithmeticCalculator {
int add(int i, int j);
int sub(int i, int j);
int mul(int i, int j);

}
package com.cn.spring.aop.impl; import org.springframework.stereotype.Component; //实现类
@Component
public class ArithmeticCalculatorImpl implements ArithmeticCalculator {
@Override
public int add(int i, int j) {
int result = i + j;
return result;
} @Override
public int sub(int i, int j) {
int result = i - j;
return result;
} @Override
public int mul(int i, int j) {
int result = i * j;
return result;
} @Override
public int div(int i, int j) {
int result = i / j;
return result;
}
}

@Aspect

public class LoggingAspect { //声明该方法是一个前置通知:在目标方法开始之前执行
@Before("execution(public int ArithmeticCalculator.*(int, int))")
public void beforeMethod(JoinPoint joinPoint) {
String methodName = joinPoint.getSignature().getName();
List<Object> args = Arrays.asList(joinPoint.getArgs()); System.out.println("The method " + methodName + " begins with " + args);
}
}
package com.cn.spring.aop.impl; import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; public class Main {
public static void main(String[] args) {
//1.创建Spring的IOC容器
ApplicationContext ctx = new ClassPathXmlApplicationContext("17-1.xml"); //2.从IOC容器中huo获取bean的实例
ArithmeticCalculator arithmeticCalculator = ctx.getBean(ArithmeticCalculator.class); //3.使用bean
int result = arithmeticCalculator.add(3, 6);
System.out.println("result:" + result);
