springboot 如何使用自定义注解+aop实现全局日志持久化操作

logPointCut() {

}

/**
* 环绕增强,相当于MethodInterceptor
*/
@Around("logPointCut()")
public Object around(ProceedingJoinPoint point) throws Throwable {
long beginTime = System.currentTimeMillis();
//执行方法
Object result = point.proceed();
//执行时长(毫秒)
long time = System.currentTimeMillis() - beginTime;

//保存日志
try {
saveSysLog(point, time);
} catch (Exception e) {
log.error("sysLog,exception:{}", e, e);
}

return result;
}

/**
* 把日志保存
*/
private void saveSysLog(ProceedingJoinPoint joinPoint, long time) {
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();

SysLog sysLog = new SysLog();
LogAnnotation logAnnotation = method.getAnnotation(LogAnnotation.class);
if (logAnnotation != null) {
//注解上的描述
sysLog.setOperation(logAnnotation.title() + "-" + logAnnotation.action());
}

//请求的方法名
String className = joinPoint.getTarget().getClass().getName();
String methodName = signature.getName();
sysLog.setMethod(className + "." + methodName + "()");
log.info("请求{}.{}耗时{}毫秒", className, methodName, time);
try {
//请求的参数
Object[] args = joinPoint.getArgs();
String params = null;
if (args.length != 0) {
params = JSON.toJSONString(args);
}

sysLog.setParams(params);
} catch (Exception e) {
log.error("sysLog,exception:{}", e, e);
}
//获取request
HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
//设置IP地址
sysLog.setIp(IPUtils.getIpAddr(request));
log.info("Ip{}，接口地址{}，请求方式{}，入参：{}", sysLog.getIp(), request.getRequestURL(), request.getMethod(), sysLog.getParams());
//用户名
String userId = httpSessionService.getCurrentUserId();
String username = httpSessionService.getCurrentUsername();
sysLog.setUsername(username);
sysLog.setUserId(userId);
sysLog.setTime((int) time);
log.info(sysLog.toString());
sysLogMapper.insert(sysLog);

}
}

3.使用方式

使用的时候，只需要在接口上贴上 @LogAnnotation
