第一步：先创建数据据库和日志类

create table logaspect(
id int unsigned primary key not null auto_increment,
logtype varchar(50) default null,
logerrorcode varchar(20) default null,
logcontent varchar(255) default null,
logdate timestamp default current_timestamp,
useridlogaspect int unsigned default null,
constraint logaspect1 foreign key(userid) references useraccount(id)
)default character set utf8mb4;
package com.gkk.ssm.po;

import java.sql.Timestamp;

/** 
 * @ClassName: SystemLogAspect 
 * @Description: TODO
 * @author: gxf
 * @date: 2019年11月8日 下午7:25:12  
 */
public class SystemLogAspectPo {
	
    private Integer id;

    private String logType;
    
    private String logErrorCode;
    
    private String logContent;
    
    private Integer userid;
    
    private Timestamp logDate;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

	public Integer getUserid() {
		return userid;
	}

	public void setUserid(Integer userid) {
		this.userid = userid;
	}

	/**
	 * @return the logType
	 */
	public String getLogType() {
		return logType;
	}

	/**
	 * @param logType the logType to set
	 */
	public void setLogType(String logType) {
		this.logType = logType;
	}

	/**
	 * @return the logErrorCode
	 */
	public String getLogErrorCode() {
		return logErrorCode;
	}

	/**
	 * @param logErrorCode the logErrorCode to set
	 */
	public void setLogErrorCode(String logErrorCode) {
		this.logErrorCode = logErrorCode;
	}

	/**
	 * @return the logContent
	 */
	public String getLogContent() {
		return logContent;
	}

	/**
	 * @param logContent the logContent to set
	 */
	public void setLogContent(String logContent) {
		this.logContent = logContent;
	}

	/**
	 * @return the logDate
	 */
	public Timestamp getLogDate() {
		return logDate;
	}

	/**
	 * @param logDate the logDate to set
	 */
	public void setLogDate(Timestamp logDate) {
		this.logDate = logDate;
	}

	
}

第二部：创建日志类的Mapper.xml和接口，Service层

package com.gkk.ssm.mapper;

import java.util.List;

import com.gkk.ssm.po.SystemLogAspectPo;

public interface SystemLogAspectMapper{

	public List<SystemLogAspectPo> findAll()throws Exception;
	public Integer insertLogAspect(SystemLogAspectPo systemLogAspectPo)throws Exception;
	public Integer deleteInformation(Integer id)throws Exception;
}
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.gkk.ssm.mapper.SystemLogAspectMapper" >
	<select id="findAll" resultType="com.gkk.ssm.po.SystemLogAspectPo">
		SELECT * FROM logaspect 
	</select>

	<insert id="insertLogAspect" parameterType="com.gkk.ssm.po.SystemLogAspectPo">
		INSERT INTO logaspect
		(logtype,logerrorcode,logcontent,userid)
		VALUES(#{logType},#{logErrorCode},#{logContent},#{userid})
	</insert>
	
	
	<delete id="deleteInformation" parameterType="int">
		delete from logaspect where id=#{id}
	</delete>
</mapper>

 */
package com.gkk.ssm.service.impl;

import java.util.List;

import com.gkk.ssm.po.SystemLogAspectPo;

/** 
 * @ClassName: SystemLogAspectService 
 * @Description: TODO
 * @author: gxf
 * @date: 2019年11月9日 上午9:42:24  
 */
public interface SystemLogAspectService {

	public List<SystemLogAspectPo> findAll()throws Exception;
	public Integer insertLogAspect(SystemLogAspectPo systemLogAspectPo)throws Exception;
	public Integer deleteInformation(Integer id)throws Exception;
}

/**

 */
package com.gkk.ssm.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import com.gkk.ssm.mapper.SystemLogAspectMapper;
import com.gkk.ssm.po.SystemLogAspectPo;

/** 
 * @ClassName: SystemLogAspectServiceImpl 
 * @Description: TODO
 * @author: gxf
 * @date: 2019年11月9日 上午9:43:51  
 */
public class SystemLogAspectServiceImpl implements SystemLogAspectService {

	@Autowired
	private SystemLogAspectMapper systemLogAspectMapper;
	@Override
	public List<SystemLogAspectPo> findAll() throws Exception {
		// TODO Auto-generated method stub
		return systemLogAspectMapper.findAll();
	}

	@Override
	public Integer insertLogAspect(SystemLogAspectPo systemLogAspectPo) throws Exception {
		// TODO Auto-generated method stub
		return systemLogAspectMapper.insertLogAspect(systemLogAspectPo);
	}

	@Override
	public Integer deleteInformation(Integer id) throws Exception {
		// TODO Auto-generated method stub
		return systemLogAspectMapper.deleteInformation(id);
	}

	/**
	 * @return the systemLogAspectMapper
	 */
	public SystemLogAspectMapper getSystemLogAspectMapper() {
		return systemLogAspectMapper;
	}

	/**
	 * @param systemLogAspectMapper the systemLogAspectMapper to set
	 */
	public void setSystemLogAspectMapper(SystemLogAspectMapper systemLogAspectMapper) {
		this.systemLogAspectMapper = systemLogAspectMapper;
	}

}

第三步：创建注解类和日志切面类

/**   
 * Copyright © 2019 eSunny Info. Tech Ltd. All rights reserved.
 * 
 * @Package: com.gkk.ssm.annotation 
 * @author: gxf  
 * @instroduction:  
 * @date: 2019年11月9日 下午2:01:11 
 */
package com.gkk.ssm.annotation;

import java.lang.annotation.*;

/** 
 * @ClassName: SystemControllerLog 
 * @Description: TODO
 * @author: gxf
 * @date: 2019年11月9日 下午2:01:11  
 */
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemControllerLog {

	String description()  default "";  
	
	String actionType()  default "";  

}

package com.gkk.ssm.aspect;

import java.lang.reflect.Method;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;

import com.gkk.ssm.annotation.SystemControllerLog;
import com.gkk.ssm.po.SystemLogAspectPo;
import com.gkk.ssm.po.UserAccount;
import com.gkk.ssm.service.impl.SystemLogAspectService;

/** 
 * @ClassName: SystemLogAspect 
 * @Description: TODO
 * @author: gxf
 * @date: 2019年11月8日 下午5:52:47  
 */

@Aspect
@Component
public class SystemLogAspect {

	@Autowired
	private SystemLogAspectService systemLogAspectService;

	private static final Logger logger = LoggerFactory.getLogger(SystemLogAspect.class);
	
	@Pointcut("execution (* com.gkk.ssm.controller..*.*(..))")
	public void controllerAspect() {
		
	}
	
	@Before("controllerAspect()")
    public void doBefore(JoinPoint joinPoint) {
        if (logger.isInfoEnabled()) {
            logger.info("before " + joinPoint);
        }
    }
	
	@After("controllerAspect()")
    public void after(JoinPoint joinPoint) {
        UserAccount userAccount = new UserAccount();
        userAccount.setId(1);
      
        try {

            String targetName = joinPoint.getTarget().getClass().getName();
            String methodName = joinPoint.getSignature().getName();
            Object[] arguments = joinPoint.getArgs();
            Class targetClass = Class.forName(targetName);
            Method[] methods = targetClass.getMethods();
            String logType = "";
            String logContent = "";
            for (Method method : methods) {
                if (method.getName().equals(methodName)) {
                    Class[] clazzs = method.getParameterTypes();
                    if (clazzs.length == arguments.length) {
                        logType = method.getAnnotation(SystemControllerLog.class).actionType();
                        logContent = method.getAnnotation(SystemControllerLog.class).description();
                        break;
                    }
                }
            }
            //*========控制台输出=========*//
            System.out.println("请求方法:" + (joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()"));
            System.out.println("方法描述:" + logContent);
            System.out.println("请求人:" + userAccount.getUsername());
            //*========数据库日志=========*//
            SystemLogAspectPo log = new SystemLogAspectPo();
            log.setUserid(userAccount.getId());
            log.setLogType(logType);
            log.setLogContent(logContent);
            log.setLogErrorCode(HttpStatus.OK.toString());
            //保存数据库
            systemLogAspectService.insertLogAspect(log);
        } catch (Exception e) {
            //记录本地异常日志
            logger.error("异常信息:{}", e.getMessage());
        }
    }

    //配置后置返回通知,使用在方法aspect()上注册的切入点
    @AfterReturning("controllerAspect()")
    public void afterReturn(JoinPoint joinPoint) {
        if (logger.isInfoEnabled()) {
            logger.info("afterReturn " + joinPoint);
        }
    }

    
    @AfterThrowing(pointcut = "controllerAspect()", throwing = "e")
    public void doAfterThrowing(JoinPoint joinPoint, Throwable e) {
             
    	UserAccount userAccount = new UserAccount();
    	userAccount.setId(1);

        String logResult = "";
        try {

            String targetName = joinPoint.getTarget().getClass().getName();
            String methodName = joinPoint.getSignature().getName();
            Object[] arguments = joinPoint.getArgs();
            Class targetClass = Class.forName(targetName);
            Method[] methods = targetClass.getMethods();
            String logType = "";
            String logContent = "";
            for (Method method : methods) {
                if (method.getName().equals(methodName)) {
                    Class[] clazzs = method.getParameterTypes();
                    if (clazzs.length == arguments.length) {
                        logType = method.getAnnotation(SystemControllerLog.class).actionType();
                        logContent = method.getAnnotation(SystemControllerLog.class).description();
                        break;
                    }
                }
            }
            /*========控制台输出=========*/
            System.out.println("异常代码:" + e.getClass().getName());
            System.out.println("异常信息:" + e.getMessage());
            System.out.println("异常方法:" + (joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()"));
            System.out.println("方法描述:" + logContent);
            System.out.println("请求人:" + userAccount.getUsername());
            /*==========数据库日志=========*/
            SystemLogAspectPo log = new SystemLogAspectPo();
            log.setUserid(userAccount.getId());
            log.setLogType(logType);
            log.setLogContent(logContent);
            log.setLogErrorCode(e.getMessage());
            //保存数据库
            systemLogAspectService.insertLogAspect(log);
        } catch (Exception ex) {
            //记录本地异常日志
            logger.error("异常信息:{}", ex.getMessage());
        }
        /*==========记录本地异常日志==========*/
        logger.error("异常方法:{}异常代码:{}异常信息:{}参数:{}", joinPoint.getTarget().getClass().getName() + joinPoint.getSignature().getName(), e.getClass().getName(), e.getMessage());

    }	
	
	
    
	/**
	 * @return the systemLogAspectService
	 */
	public SystemLogAspectService getSystemLogAspectService() {
		return systemLogAspectService;
	}

	/**
	 * @param systemLogAspectService the systemLogAspectService to set
	 */
	public void setSystemLogAspectService(SystemLogAspectService systemLogAspectService) {
		this.systemLogAspectService = systemLogAspectService;
	}
	
}

第四步：修改配置文件

在springmvc.xml中添加

<!--开启aopproxy-target-class="true"默认是false,更改为true时使用的是cglib动态代理,这样只能实现对Controller层的日志记录-->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
    <!--扫描日志记录切面-->
    <context:component-scan base-package="package com.gkk.ssm.aspect" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
    </context:component-scan>

效果：

总结：

日志模块大致是完成了，但还有不少地方需要完善，比如日志表中插入的用户id是直接指定为1的，这是因为，我还没把登陆的用户id收集进项目中，后续开发了登录拦截再添加进去。
