JAVA项目中怎么实现一个通用日志记录功能

今天就跟大家聊聊有关JAVA项目中怎么实现一个通用日志记录功能，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

使用Aop记录操作日志

添加aop

public class LogAopHandler {  @Autowired  private AuditLogDao auditLogDao;    public Object doSaveLog(ProceedingJoinPoint joinPoint) throws Throwable {     MethodSignature method = (MethodSignature) joinPoint.getSignature();    String methodName = method.getName();    Object[] objects = joinPoint.getArgs();    String requestBody = null;    if (objects!=null && objects.length>0) {      for (Object object : objects) {        if (object == null) {          requestBody = null;//POST接口参数为空 比如删除XXX        }else if (object instanceof String) {          requestBody = (String) object;//有些接口直接把参数转换成对象了        }else {          requestBody = JSONObject.tojsONString(object);        }      }    }    //只记录POST方法的日志    boolean isNeedSaveLog = false;    //此处不能用getAnnotationByType 是JAVA8的特性,因为注解能够重名,所以得到的是数组    RequestMapping annotation = method.getMethod().getAnnotation(RequestMapping.class);    for (RequestMethod requestMethod : annotation.method()) {      if (requestMethod==RequestMethod.POST) {        isNeedSaveLog = true;      }    }    JSONObject requestBodyJson = null;    try {      requestBodyJson = JSONObject.parseObject(requestBody);    } catch (Exception e) {      //do nothing 即POST请求没传body    }    httpservletRequest request = RequestContextUtil.getRequestByCurrentContext();    String userName = RequestContextUtil.getUserNameByCurrentContext();    if (StringUtil.isEmpty(userName)) {      try {        userName = DmsCache.get(requestBodyJson.getString("userName")).getName();      } catch (Exception e) {        userName = RequestContextUtil.getAsynUserInfoByAutoDeploy().getName();      }    }    //得到request的参数后让方法执行它     //注意around的情况下需要返回result 否则将不会返回值给请求者    Object result = joinPoint.proceed(objects);    try {      JSONObject resultJson = JSONObject.parseObject(result.toString());      if (isNeedSaveLog) {//如果是POST请求 则记录日志        LogTypeEnum logTypeEnum = LogTypeEnum.getDesByMethodName(methodName);        if (logTypeEnum != null) {          AuditLogEntity auditLogEntity = new AuditLogEntity();          auditLogEntity.setUuid(StringUtil.createRandomUuid());          auditLogEntity.setOperator(userName);          auditLogEntity.setRequestIp(request.getRemoteAddr());          auditLogEntity.setRequestUrl(request.getRequestURI().replace("/cloud-master", ""));          auditLogEntity.setEventType(logTypeEnum.geTKEy());          auditLogEntity.setEventDesc(logTypeEnum.getDescription());          auditLogEntity.setRequest(requestBody);          int isSuccess = "200".equals(resultJson.getString("code")) ? 1 : 0;          auditLogEntity.setSuccessFlag(isSuccess);          auditLogEntity.setResponse(result.toString());          auditLogEntity.setCreateTime(new Date());          auditLogDao.insert(auditLogEntity);        }      }    } catch (Exception e) {      e.printStackTrace();    }    return result;  } }
