springboot + AOP 日志

一. 简介

            记录日志方便排错，记录操作记录。通常有俩层需要加日志：controller层和service层。

            controller层的日志使用Log打印信息，service层的日志使用数据库记录操作日志。

Controller层	通过添加一个AOP切面，监控controller层的所有方法： 调用之前打印请求信息，包含URL,HTTP_METHOD,IP,CLASS_METHOD,ARGS； 在方法完成后，打印返回的请求结果，包含code, msg。
ServiceImpl层	创建一张日志表sys_log, 创建一个SysLogService接口和一个SysLogServiceImpl实现类。里面包含一个saveSysLog(...)方法，该方法加@Transactional注解，内置的传播行为为PROPAGATION_REQUIRES_NEW。 在每个其他的service层中注入SysLogService，在每个方法最后加一个插入日志表的操作。 此处不展示。

二. 代码

2.1 切面类

package com.yzx.operateplatform.aspect;

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.yzx.operateplatform.vo.ResultVO;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

/**
 * 日志切面类
 */
@Aspect
@Component
public class LogAspect {

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

    // ..表示包及子包 该方法代表controller层的所有方法
    @Pointcut("execution(public * com.yzx.operateplatform.controller..*.*(..))")
    public void controllerMethod() {
    }


    @Before("controllerMethod()")
    public void LogRequestInfo(JoinPoint joinPoint) throws Exception {

        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        StringBuffer requestLog = new StringBuffer();
        requestLog.append("请求信息：")
                .append("URL = {" + request.getRequestURI() + "},\t")
                .append("HTTP_METHOD = {" + request.getMethod() + "},\t")
                .append("IP = {" + request.getRemoteAddr() + "},\t")
                .append("CLASS_METHOD = {" + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName() + "},\t");

        if(joinPoint.getArgs().length == 0) {
            requestLog.append("ARGS = {} ");
        } else {
            requestLog.append("ARGS = " + new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL)
                    .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() + "\t" + resultVO.getMsg());
    }

}

注意：

        如果有BaseController的话，不需要被日志扫描，可以通过添加不扫描路径即可。如下：

2.2 ResultVO类

package com.yzx.codedemo.vo;

import io.swagger.annotations.ApiModelProperty;

/**
 * 返回结果类
 *
 * @param <T> 类型
 */

public class ResultVO<T> {

    @ApiModelProperty("状态码 0失败 1成功 ")
    private Integer code;
    @ApiModelProperty("返回信息")
    private String msg;
    @ApiModelProperty("返回数据")
    private T data;

    public ResultVO(Integer code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    public ResultVO(Integer code, String msg, T data) {
        this.code = code;
        this.msg = msg;
        this.data = data;
    }

    /**
     * 请求成功  状态码 1
     *
     * @param msg 返回信息
     * @param <T> 类型
     * @return ResultVO
     */
    public static <T> ResultVO getSuccess(String msg) {
        return new ResultVO(1, msg);
    }

    /**
     * 请求成功  状态码 1
     *
     * @param msg  返回信息
     * @param data 返回对象
     * @param <T>  类型
     * @return ResultVO
     */
    public static <T> ResultVO getSuccess(String msg, T data) {
        return new ResultVO(1, msg, data);
    }

    /**
     * 请求失败   状态码 0
     *
     * @param msg 返回信息
     * @param <T> 类型
     * @return ResultVO
     */
    public static <T> ResultVO getFailed(String msg) {
        return new ResultVO(0, msg);
    }

    /**
     * 请求失败  状态 0
     *
     * @param msg  返回信息
     * @param data 返回数据
     * @param <T>  类型
     * @return ResultVO
     */
    public static <T> ResultVO getFailed(String msg, T data) {
        return new ResultVO(0, msg, data);
    }


    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

}

2.3 Controller类

package com.yzx.codedemo.controller.user;

import com.yzx.codedemo.entity.user.SysUser;
import com.yzx.codedemo.service.user.SysUserService;
import com.yzx.codedemo.vo.PageVO;
import com.yzx.codedemo.vo.ResultVO;
import com.yzx.codedemo.vo.user.SysUserVO;
import io.swagger.annotations.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import springfox.documentation.annotations.ApiIgnore;

import java.util.List;

@Api(tags = {"SysUserController"}, description = "用户Controller")
@RestController
@RequestMapping(value = "/sysuser")
public class SysUserController {

    @Autowired
    private SysUserService sysUserService;


    @ApiOperation("查询用户分页列表")
    @ApiImplicitParams({
            @ApiImplicitParam(paramType = "query", dataType = "Long", name = "currentPage", value = "当前页码", required = true),
            @ApiImplicitParam(paramType = "query", dataType = "Long", name = "pageSize", value = "每页记录数", required = true),
            @ApiImplicitParam(paramType = "query", dataType = "String", name = "userName", value = "用户名称", required = false),
            @ApiImplicitParam(paramType = "query", dataType = "String", name = "phone", value = "手机号", required = false),
            @ApiImplicitParam(paramType = "query", dataType = "Long", name = "userState", value = "用户状态: 0删除 1正常", required = false),
            @ApiImplicitParam(paramType = "query", dataType = "String", name = "starttime", value = "开始时间 格式：yyyy-MM-dd HH:mm:ss", required = false),
            @ApiImplicitParam(paramType = "query", dataType = "String", name = "endtime", value = "结束时间 格式：yyyy-MM-dd HH:mm:ss", required = false)
    })
    @GetMapping(value = "/page")
    public ResultVO<PageVO<SysUserVO>> selectSysUserPage(@ApiIgnore SysUserVO sysUserVO) {
        try {
            return this.sysUserService.selectSysUserPage(sysUserVO);
        } catch (Exception e) {
            e.printStackTrace();
            return ResultVO.getSuccess("查询用户分页列表失败");
        }
    }


}

2.3 测试

每次调用controller层的代码的方法，都会打印日志信息：
