Spring Boot AOP

1、配置pom.xml。

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2、AOPConfig.java

package com.idodo.demo.conf;

import java.util.Arrays;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.context.annotation.Configuration;

@Aspect
@Configuration
public class AOPConfig {
  
  // Controller的所有方法，在执行前后都会进入functionTestAop方法
  @Around("@within(org.springframework.stereotype.Controller) ")
  public Object functionTestAop(final ProceedingJoinPoint pjp) throws Throwable {
    try {
      Object[] args = pjp.getArgs();
      System.out.println("前：args:" + Arrays.asList(args));

      // 继续处理原有调用
      Object o = pjp.proceed();

      System.out.println("后：return :" + o);
      return o;

    } catch (Throwable e) {
      throw e;
    }
  }
}

3、控台台输出。
前：args:[jzh]
后：return :hello jzh
