Java实现幂等注解

拦截器
@Aspect
@Component
public class NoRepeatAspect {
@Resource
private RedisTemplate<String, Object> redisTemplate;
@Pointcut("@annotation(com.sunline.project.aop.NoRepeat) || @within(com.sunline.project.aop.NoRepeat)")
public void pointCut(){}
@Around("pointCut()")
private Object around(ProceedingJoinPoint point) {
try {
// 获取当前用户的token
Subject currStaff = SecurityUtils.getSubject();
UserVo user = (UserVo) currStaff.getPrincipal();
String token = user.getToken();
StaticLog.info("检测是否重复提交");
StaticLog.info("point:{}", point);
// 获取当前请求的方法名
MethodSignature signature = (MethodSignature) point.getSignature();
Method method = signature.getMethod();
String name = method.getName();
StaticLog.info("token:{},======methodName:{}", token, name);
if (redisTemplate.hasKey(token+name)) {
StaticLog.error("监测到重复提交>>>>>>>>>>");
return ResponseData.fail(ResponseCode.FAIL_CODE, "请勿重复提交");
}
// 获取注解
NoRepeat annotation = method.getAnnotation(NoRepeat.class);
Long timeout = annotation.timeOut();
// 此处我用token和请求方法名为key存入redis中,有效期为timeout 时间, 也可以使用ip地址做为key
redisTemplate.opsForValue().set(token+name, token+name, timeout, TimeUnit.SECONDS);
return point.proceed();
} catch (Throwable throwable) {
StaticLog.error("=====>>>>>>操作失败:{}", throwable);
return ResponseData.fail(ResponseCode.FAIL_CODE, "操作失败");
}
}
}
注解
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface NoRepeat {
// 默认失效时间
long timeOut() default 10;
}
测试:@NoRepeat(timeOut = 5)
timeOut默认时间为10s
@NoRepeat(timeOut = 5)
@GetMapping(value = "/test")
@ApiOperation(value = "测试幂等注解")
@SysLogs("测试幂等注解")
@ApiImplicitParam(paramType = "header", name = "Authorization", value = "身份认证Token")
public ResponseData<T> testIdempotent() {
try {
System.err.println(new Date());
return ResponseData.ok(ResponseCode.SUCCESS_CODE, "操作成功");
} catch (Exception e) {
StaticLog.error("操作失败:{}", e);
return ResponseData.ok(ResponseCode.FAIL_CODE, "操作失败");
}
}
