spring boot aop custom annotations operation log storage element

First add aop depend on the maven

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

Logs entity class

	private String name;//操作人
	private String method;//具体路径
	private String parameter;//参数
	private String consuming;//操作时长
	private String content;//内容
	private String time;//创建时间

	public String getMethod() {
		return method;
	}
	public void setMethod(String method) {
		this.method = method;
	}
	public String getJobnum() {
		return jobnum;
	}
	public void setJobnum(String jobnum) {
		this.jobnum = jobnum;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}
	public String getTime() {
		return time;
	}
	public void setTime(String time) {
		this.time = time;
	}
	public String getIp() {
		return ip;
	}
	public void setIp(String ip) {
		this.ip = ip;
	}
	public String getParameter() {
		return parameter;
	}
	public void setParameter(String parameter) {
		this.parameter = parameter;
	}
	public String getConsuming() {
		return consuming;
	}
	public void setConsuming(String consuming) {
		this.consuming = consuming;
	}

Then create a custom meta-annotation

package com.annotation;

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

/** 
* @author  作者 : 小布
* @version 创建时间 : 2019年6月10日 上午10:10:52 
* @explain 类说明 : 操作日志元注解
*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface RecordLog {
	String value() default "";
}

Creating our implementation class

import java.lang.reflect.Method;

import org.apache.shiro.SecurityUtils;
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.beans.factory.annotation.Autowired;
import org.springframework.core.LocalVariableTableParameterNameDiscoverer;
import org.springframework.stereotype.Component;
/** 
* @author  作者 : 小布
* @version 创建时间 : 2019年6月10日 上午10:17:06 
* @explain 类说明 : 
*/
@Aspect
@Component
public class LogAspect {

	@Autowired接口
	private MasterMapper masterMapper;//引入 mapper 接口 实现添加日志入库

	@Pointcut("@annotation(com.annotation.RecordLog)")//自定义元注解
	public void pointcut() {
	}

    @Around("pointcut()")
    public Object around(ProceedingJoinPoint point){
        Object result = null;
        long beginTime = System.currentTimeMillis();
        try {
            // 执行方法
            result = point.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        // 执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;

        //保存日志
        saveLog(point, time);
        return result;
    }

    public void saveLog(ProceedingJoinPoint joinPoint, long time){
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        Logs sysLog = new Logs();//对应的日志实体
        RecordLog logAnnotation = method.getAnnotation(RecordLog.class);//自定义元注解
        if (logAnnotation != null) {
            // 注解上的描述
            sysLog.setContent(logAnnotation.value());
        }
        // 请求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        sysLog.setMethod(className + "." + methodName + "()");
        // 请求的方法参数值
        Object[] args = joinPoint.getArgs();
        // 请求的方法参数名称
        LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();
        String[] paramNames = u.getParameterNames(method);
        if (args != null && paramNames != null) {
            String params = "";
            for (int i = 0; i < args.length; i++) {
                params += "  " + paramNames[i] + ": " + args[i];
            }
            sysLog.setParameter(params);
        }

        SysUser user = (SysUser) SecurityUtils.getSubject().getPrincipal();//获取 shiro对象
        
        sysLog.setName(user.getFullName());//也可以获取 session 等缓存
        sysLog.setConsuming((int) time+"");//操作时长  毫秒
        masterMapper.isnertLogs(sysLog);//添加日志表
        
    }
    
}

Achieve only need to add a meta-annotation @RecordLog ( "Operation content") on the method to
the final results of the database
