Springboot集成注解日志切面

1、引入依赖

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

2、自定义注解

package com.example.demo.aspect;

import java.lang.annotation.*;

/**
 * @Author: pandafox
 * @Desctription: TODO
 * @Date: Created in 2021/1/1 19:53
 * @Version: 1.0
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {
    
    
}

3、日志切面

package com.example.demo.aspect;

import com.google.gson.Gson;
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 org.springframework.stereotype.Component;

import java.lang.reflect.Method;

/**
 * @Author: pandafox
 * @Desctription: TODO
 * @Date: Created in 2021/1/1 19:56
 * @Version: 1.0
 */
@Aspect
@Component
@Slf4j
public class SysLogAspect {
    
    

    @Pointcut("@annotation(com.example.demo.aspect.SysLog)")
    public void log() {
    
    

    }

    @Around(value = "log()")
    public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable {
    
    
        //1.获取包名和类名
        String className = joinPoint.getTarget().getClass().getName();

        //2.获取方法名
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();

        //3.打印入参出参日志
        Object[] args = joinPoint.getArgs();
        Gson gson = new Gson();
        log.info("{}.{}() 执行, Params ==> " + gson.toJson(args), className, method.getName());
        Object proceed = joinPoint.proceed();
        log.info("{}.{}() 执行, Returns ==> " + gson.toJson(proceed), className, method.getName());
        return proceed;
    }

}

4、使用方式

在对应方法上面加上@SysLog()注解

	@SysLog()
    @PostMapping("/test")
    @ResponseBody
    public Map<String, Object> getMsg(String id, String name) {
    
    
        Map<String, Object> map = new HashMap<>();
        map.put("result", "response msg");
        map.put("id", id);
        map.put("name", name);
        return map;
    }

5、效果

2021-01-01 20:36:45.453  INFO 3956 --- [nio-8080-exec-7] com.example.demo.aspect.SysLogAspect     : com.example.demo.controller.TestController.getMsg() 执行, Params ==> ["100","zhangsan"]
2021-01-01 20:36:45.466  INFO 3956 --- [nio-8080-exec-7] com.example.demo.aspect.SysLogAspect     : com.example.demo.controller.TestController.getMsg() 执行, Returns ==> {
    
    "result":"response msg","name":"zhangsan","id":"100"}
