一、引入必要依賴

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><!-- aop依賴 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency><!-- mysql驅動 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.41</version></dependency><!-- druid數據源驅動 --><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.1.10</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency>

二、自定義注解

定義一個方法級別的@Log注解，用于標注需要監控的方法：

@Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface Log {String value() default ""; }

三、建立數據表和實體類

數據表：

實體類：

@Data @TableName("sys_handle_log") public class SysHandleLog extends Model<SysHandleLog> {@TableId(value = "id", type = IdType.AUTO)private Integer id;@ApiModelProperty(value = "執行人")@TableField("create_user")private String createUser;@ApiModelProperty(value = "操作")@TableField("operation")private String operation;@ApiModelProperty(value = "執行的方法")@TableField("method")private String method;@ApiModelProperty(value = "攜帶參數")@TableField("params")private String params;@ApiModelProperty(value = "耗時")@TableField("spend_time")private Integer spendTime;@ApiModelProperty(value = "用戶ip")@TableField("ip")private String ip;@ApiModelProperty(value = "位置")@TableField("location")private String location;@ApiModelProperty(value = "創建時間")@TableField("create_time")private Date createTime;@Overrideprotected Serializable pkVal() {return this.id;} }

四、日志切面

@Aspect @Component public class UserOperateAspect{@Autowiredprivate SysHandleLogMapper sysHandleLogMapper;@Pointcut("@annotation(com.project.common.annotation.UserOperateLog)")public void pointcut() { }@Around("pointcut()")public Object around(ProceedingJoinPoint point) {Object result = null;long beginTime = System.currentTimeMillis();try {// 執行方法result = point.proceed();} catch (Throwable e) {e.printStackTrace();}// 執行時長(毫秒)long time = System.currentTimeMillis() - beginTime;// 保存日志saveLog(point, time);return result;}private void saveLog(ProceedingJoinPoint joinPoint, long time) {MethodSignature signature = (MethodSignature) joinPoint.getSignature();Method method = signature.getMethod();SysHandleLog sysHandleLog = new SysHandleLog();UserOperateLog logAnnotation = method.getAnnotation(UserOperateLog.class);if (logAnnotation != null) {// 執行的操作sysHandleLog.setOperation(logAnnotation.value());}// 請求的方法名String className = joinPoint.getTarget().getClass().getName();String methodName = signature.getName();sysHandleLog.setMethod(className + "." + methodName + "()");// 請求的方法參數值Object[] args = joinPoint.getArgs();// 請求的方法參數名稱LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();String[] paramNames = u.getParameterNames(method);if (args != null && paramNames != null) {String params = "";for (int i = 0; i < args.length; i++) {if(args[i] instanceof Project) {Class<?> object = args[i].getClass();//獲取實體類的所有屬性，返回Field數組Field[] fields = object.getDeclaredFields();for (Field field : fields) {//field.toString() 格式：private java.lang.String com.project.sys.entity.Project.projectProperty 只需要projectPropertytry {field.setAccessible(true);if (field.get(args[i]) != null && !"".equals(field.get(args[i]))) {params += " " + StringUtils.substringAfterLast(field.toString(), ".") + ": " + field.get(args[i]);}} catch (IllegalAccessException e) {e.printStackTrace();}}}else if(args[i]!=null&&!args[i].equals("")){params += " " + paramNames[i] + ": " + args[i];}}sysHandleLog.setParams(params);}// 獲取requestHttpServletRequest request =((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();// 獲取ip及地址String IP=IPUtils.getIpAddress(request);sysHandleLog.setIp(IP);sysHandleLog.setLocation(AddressUtils.getAddressByIP(IP).replaceAll("\\d+","").replace("|",""));//獲取用戶名SysUserInfo userInfo= (SysUserInfo) request.getSession().getAttribute(SystemConst.SYSTEM_USER_SESSION);sysHandleLog.setCreateUser(userInfo.getName());sysHandleLog.setSpendTime((int) time);sysHandleLog.setCreateTime(new Date());// 保存系統日志sysHandleLogMapper.insert(sysHandleLog);} }

五、控制器

@Controller @RequestMapping("sys-handlelog-info/") public class SysHandleLogController {@Autowiredprivate SysHandleLogService sysHandleLogService;@AutowiredSysHandleLogMapper sysHandleLogMapper;@GetMapping("init")public String init() {return "sys/handlelog/list";}@PostMapping("list")@ResponseBodypublic LayTableResult list(Integer page, Integer limit, SysHandleLog sysHandleLog) {return sysHandleLogService.list(page, limit, sysHandleLog);}@GetMapping("deleteAll")public String deleteAll() {sysHandleLogMapper.deleteHandleLog();return "sys/handlelog/list";} }

注：部分dao層代碼沒給出，這里主要給出思路
