===========>**maven依赖**

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>
    
        
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.54</version>
            <scope>compile</scope>
        </dependency>

===========> **最简单的方式,直接对Controller切点,对所有的方法进行控制**

package com.fuck.don’t CopyMe;  
import com.xxx.edu.admin.entity.TSysLog;  
import org.aspectj.lang.JoinPoint;  
import org.aspectj.lang.annotation.After;  
import org.aspectj.lang.annotation.Aspect;  
import org.aspectj.lang.annotation.Before;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.stereotype.Component;  
import javax.servlet.http.HttpServletRequest;  
import java.util.Date;

@Aspect  
@Component  
public class LoggerHandler \{

@Autowired
    private TSysLogServcice loggerService;//日志逻辑层,增查操作
    @Autowired
    private HttpServletRequest httpServletRequest;
    
     * 记录操作controller之前记录
     * execution(* com.xxx.xxxx.web.*Controller.*(..))
     * ***MMP这个编辑器显示有问题,自行百度下语法,注解里面注意星号/点号的使用,星号(所有的包,所有的controller类下所有方法),点(两点说明参数不限),请把上述"所有"两个字替换为星号***
    @Before("execution(* com.xxx.xxxx.web.*Controller.*(..))")
    public void beforeAddLog(JoinPoint joinPoint) {
        this.addLog(joinPoint, "before");
    }
    
     * 记录操作controller之后记录
    @After("execution(* com.xxx.xxxx.web.*Controller.*(..))")
    public void afterAddLog(JoinPoint joinPoint) {
        this.addLog(joinPoint, "after");
    }
    
     * 记录日志
    public void addLog(JoinPoint joinPoint, String type) {
        TSysLog sysLog = new TSysLog();//日志实例
        sysLog.setVisitTime(new Date());//访问时间
         String username = SecurityContextHolder.getContext().getAuthentication().getName();;//通过springsecurity/shiro获取登录用户
        sysLog.setUsername(username);//登录用户的名称
        String remoteAddr = httpServletRequest.getRemoteAddr();//客户端远程ip地址
        sysLog.setIp(remoteAddr);
        Class declaringType = joinPoint.getSignature().getDeclaringType();
        String methodName = joinPoint.getSignature().getName();
        sysLog.setMethod(type + ":" + declaringType + ":" + methodName);
        loggerService.addLog(sysLog);
    	}
    	}

===========> **实际中日志需要灵活的使用,不是每个controller都要去打印,解决思路是,给日志生成一个注解,把注解设置为切点,所有的通知都以这个切点进行,给需要日志的方法加上注解即可**

package com.xxx.core;  
import java.lang.annotation.\*;  
@Retention(RetentionPolicy.RUNTIME)//什么时候使用该注解，我们定义为运行时；  
@Target(\{ElementType.METHOD\})//注解用于什么地方，我们定义为作用于方法上；  
@Documented//注解是否将包含在 JavaDoc 中；

public @interface WebLog \{

String description() default "";
