springboot 切面编程 日志模块

1 创建一个切面类

 注意： 

saveLog 这个方法我加了获取request里的缓存seeion的用户信息，可根据自己业务调整

package com.another.aspect;

import com.alibaba.fastjson.JSON;
import com.another.aspect.anno.SysLog;
import com.another.aspect.service.SysLogService;
import com.another.book.model.User;
import com.another.common.HttpSessionUtil;

import org.springframework.web.context.request.RequestContextHolder;

import javax.servlet.http.HttpServletRequest;
import java.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

/**

@Aspect
@Component
public class LogAspect {

//    private final static Logger logger = LoggerFactory.getLogger(LogAspect.class);


    @Autowired
    private SysLogService sysLogService;


    // ..表示包及子包 该方法代表controller层的所有方法

    }

/*

                    .writeValueAsString(joinPoint.getArgs()[0]) + "");

        logger.info(requestLog.toString());
    }


    @AfterReturning(returning = "resultVO", pointcut = "controllerMethod()")
    public void logResultVOInfo(ResultVO resultVO) throws Exception {
        logger.info("请求结果：" + resultVO.getCode() + "	" + resultVO.getMsg());
    }
*/


    /**
     * 环绕通知 @Around  ， 当然也可以使用 @Before (前置通知)  @After (后置通知)
     *
     * @param point
     * @return

     */
    @Around("controllerMethod()")
    public Object around(ProceedingJoinPoint point) throws Throwable {
        long beginTime = System.currentTimeMillis();
        Object result = point.proceed();
        long time = System.currentTimeMillis() - beginTime;
        try {
            saveLog(point, time);
        } catch (Exception e) {

    private void saveLog(ProceedingJoinPoint joinPoint, long time) {
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();

            }
            sysLogBO.setParams(list.toString());
        } catch (Exception e) {
        }
        sysLogService.save(sysLogBO);
    }

}

2  日志service

package com.another.aspect.service;

import com.another.aspect.SysLogBO;
import com.another.book.dao.SysLogDao;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageImpl;
import org.springframework.data.domain.PageRequest;
import org.springframework.stereotype.Service;

import javax.persistence.EntityManager;
import javax.persistence.TypedQuery;
import javax.persistence.criteria.CriteriaBuilder;
import javax.persistence.criteria.CriteriaQuery;
import javax.persistence.criteria.Root;
import java.util.List;
import java.util.Map;

/**
 * @author kql
 * @date 2018/6/4 9:41
 * @email 1529949535@qq.com
 */
@Slf4j
@Service
public class SysLogService {

    @Autowired
    private SysLogDao sysLogDao;

    @Autowired
    private EntityManager entityManager;

    public boolean save(SysLogBO sysLogBO) {
        //输出日志
        log.info(sysLogBO.toString());
        //保存
        sysLogDao.save(sysLogBO);
        return true;
    }
}

3 日志实体类：

package com.another.aspect;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

/**
 * 系统日志bo
 * @author kuangQingLin
 * @version 1.0
 * @date 2019/12/12/012 14:48
 **/
@ApiModel("系统日志bo")
@Table(name = "log")
@Entity
@JsonIgnoreProperties(value = {"hibernateLazyInitializer", "handler"})
@Data
public class SysLogBO {
    /**
     * 主键id
     */
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Id
    @Column(name = "id")
    @ApiModelProperty(value = "主键id ", required = true)
    private Integer id;

    /**
     * 类名
     */
    @Column(name = "class_name")
    private String className;

    /**
     * 方法名
     */
    @Column(name = "method_name")
    private String methodName;

    /**
     * 参数
     */
    @Column(name = "params")
    private String params;

    /**
     * 执行时间，毫秒
     */
    @Column(name = "execute_time")
    private Long executeTime;

    /**
     * 备注（方法的备注）
     */
    @Column(name = "remark")
    private String remark;

    /**
     * 执行开始时间
     */
    @Column(name = "create_date")
    private String createDate;

    /**
     * 操作人
     */
    @Column(name = "operator_name")
    private String operatorName;
}

4：自定义日志注解：

package com.another.aspect.anno;
 
import java.lang.annotation.*;
 
/**
 * 定义系统日志注解
 * @author zhuzhe
 * @date 2018/6/4 9:24
 * @email 1529949535@qq.com
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {
    String value() default "";
}

　　5 代码里使用:

　　这里举例controller,   

 @SysLog("查询审批")  

    @GetMapping("/{id}")
    @ApiOperation("查询审批")
    @SysLog("查询审批")
    public String getApprove(@PathVariable("id") int id) {
        logger.info("查询审批");
        approveService.select(id);
        return "index/index";
    }

6 dao：

这里重写的方法是我业务中做统计时候用的，可自行更改

package com.another.book.dao;

import com.another.aspect.SysLogBO;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;

import java.util.List;
import java.util.Map;

/**
 * @author kuangQingLin
 * @version 1.0
 * @date 2019/12/12/012 15:09
 **/
public interface SysLogDao  extends JpaRepository<SysLogBO,Integer> {

    /**
     * 分组统计
     * @return
     */
    @Query(value = "SELECT DATE_FORMAT(create_date,'%Y-%m') months,COUNT(id) count FROM log GROUP BY months  ORDER BY months",nativeQuery = true)
    List<Map> select();
}

注意：本例持久层用的jpa
