        </dependency>

第二步創(chuàng)建自定義日志注解類

package com.example.aop.log.annotion;
import java.lang.annotation.*;
/**
 * @author zhr_java@163.com
 * @date 2022/3/29 20:56
 */
@Inherited
@Target({ElementType.METHOD})
@Retention(value = RetentionPolicy.RUNTIME)
@Documented
public @interface LogNotice {}

第三步切面設(shè)計(jì)，掃描上面的注解

package com.example.aop.log.aop;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.core.DefaultParameterNameDiscoverer;
import org.springframework.stereotype.Component;
import java.lang.reflect.Method;
import java.util.HashMap;
import java.util.Map;
/**
 * @author zhr_java@163.com
 * @date 2022/3/29 20:59
 */
@Aspect
@Component
public class LogAspect {
  @Pointcut("@annotation(com.example.aop.log.annotion.LogNotice)")
  public void doLog() {}
  @Around("doLog()")
  public Object insertLog(ProceedingJoinPoint joinPoint) throws Throwable {
    Object object = joinPoint.proceed();
    try {
      HashMap paramsMap;
      Signature signature = joinPoint.getSignature();
      Method method = ((MethodSignature) signature).getMethod();
      String methodName = method.getName();
      String className = method.getDeclaringClass().getName();
      paramsMap = (HashMap) getParams(joinPoint, method);
      // 打印日志，可以記錄到數(shù)據(jù)庫(kù)的日志表里面，等到有客戶反饋的時(shí)候好去查詢?nèi)罩?
      System.out.println(
          "methodName: " + methodName + "; className: " + className + "; paramsMap:" + paramsMap);
      // 也可以記錄請(qǐng)求當(dāng)前接口耗費(fèi)的時(shí)間
    } catch (Exception e) {
      // 如果在日志記錄的過(guò)程中出現(xiàn)問(wèn)題，那么要處理一下異常，不要直接拋出，此處做成消息隊(duì)列通知或者打印日志
    }
    // 此處要進(jìn)行返回代理的對(duì)象，如果沒(méi)有返回的話，前端是收不到數(shù)據(jù)的
    return object;
  }
  private Map<String, Object> getParams(ProceedingJoinPoint joinPoint, Method method) {
    // get parameter names
    String[] parameterNames = new DefaultParameterNameDiscoverer().getParameterNames(method);
    Object[] args = joinPoint.getArgs();
    Map<String, Object> params = new HashMap<>(8);
    if (parameterNames != null && parameterNames.length != 0) {
      for (int i = 0; i < parameterNames.length; i++) {
        params.put(parameterNames[i], args[i]);
      }
    return params;
}

第四步把自定義的注解放到你的接口上面

package com.example.demo.controller;
import com.example.aop.log.annotion.LogNotice;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * @author zhr_java@163.com
 * @date 2022/3/29 20:50
 */
@RestController
@RequestMapping("/person")
public class PersonController {
  //在此處加上你自定義的注解（@LogNotice）
  @LogNotice
  @GetMapping("get_person")
  public String getPerson(Integer numbers) {
    return "123";
  }
}

第五步測(cè)試
