日志模块自定义@SkipLogAspect注解跳过切面

文章目录

1.增加原因

因为如果参数是一些大对象，比如HttpServletRequest request，在转化为json的时候就会导致OOM，所以选择新增一个注解让用户自己灵活的决定是否添加日志切面

2.common-log4j2-starter

1.目录结构

2.SkipLogAspect.java 自定义注解

package cn.sunxiansheng.log4j2.annotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * Description: 跳过日志切面的注解
 *
 * @Author sun
 * @Create 2025/1/24 18:08
 * @Version 1.0
 */
@Target({ElementType.METHOD, ElementType.TYPE}) // 可以标注在类或方法上
@Retention(RetentionPolicy.RUNTIME) // 运行时生效
public @interface SkipLogAspect {
}

3.LogAspect.java

1.核心改动

2.完整代码

package cn.sunxiansheng.log4j2.aspectj;

import cn.sunxiansheng.log4j2.annotation.SkipLogAspect;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.ProceedingJoinPoint;
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 java.lang.reflect.Method;

/**

@Aspect
@Slf4j
public class LogAspect {

    private static final Gson GSON = new GsonBuilder()
            .setPrettyPrinting()
            .disableHtmlEscaping()
            .create();

    private static final String ANSI_RESET = "\u001B[0m";
    private static final String ANSI_CYAN = "\u001B[92m";

    @Pointcut("execution(public * *..controller..*(..)) || " +
            "execution(public * *..service..*(..))")
    public void applicationPackagePointcut() {
        // 切点定义
    }

    @Around("applicationPackagePointcut()")
    public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable {
        // 获取目标类和方法
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        Class<?> targetClass = joinPoint.getTarget().getClass();

        // 检查是否存在 @SkipLogAspect 注解
        if (method.isAnnotationPresent(SkipLogAspect.class) ||
                targetClass.isAnnotationPresent(SkipLogAspect.class)) {
            // 直接执行目标方法，不记录日志
            return joinPoint.proceed();
        }

        // 正常记录日志逻辑
        String className = signature.getDeclaringTypeName();
        String methodName = signature.getName();
        Object[] args = joinPoint.getArgs();
        String requestParams = GSON.toJson(args);

        log.info("==> 进入方法: {}.{}()", className, methodName);
        log.info("参数:\n" + ANSI_CYAN + "{}" + ANSI_RESET, requestParams);

        long startTime = System.currentTimeMillis();
        Object result = joinPoint.proceed();
        long endTime = System.currentTimeMillis();

        String response = GSON.toJson(result);

        log.info("<== 退出方法: {}.{}() | 耗时: {} ms", className, methodName, endTime - startTime);
        log.info("返回值:\n" + ANSI_CYAN + "{}" + ANSI_RESET, response);

        return result;
    }
}

3.common-log4j2-starter-demo

1.目录结构

2.TraceController.java 新增方法，测试跳过日志切面的注解

/**
 * 测试跳过日志切面的注解
 *
 * @param msg
 * @return
 */
@SkipLogAspect
@RequestMapping("/skipLogAspect")
public String skipLogAspect(String msg) {
    return "skip log aspect";
}

3.测试
