JarCasting
- 网关分布式限流实现,基于redis+lua
- 1.基于redis令牌桶形式
- 2.限流预警
- 3.异步日志链路追踪
使用方式
maven依赖
<dependency>
<groupId>com.github.sunywdev</groupId>
<artifactId>routelimit</artifactId>
<version>1.0.1</version>
</dependency>
针对接口配置固定限流数量
@GetMapping("/logerror")
@Log(name = "限流测试")
@RouteLimiter(acquiredQuantity = 1,burstCapacity = 2,repleniShrate = 1)
public Map<String, Object> logError() {
Map<String, Object> respMap = new HashMap<>();
respMap.put("code", "200");
respMap.put("msg", "success");
return respMap;
}
全局限流,根据请求接口地址进行流量限制
route:
#每秒产生的令牌数量
replenishrate: 1
#桶内令牌容量
burstcapacity: 10
#每次获取令牌数量
acquiredquantity: 1
邮件通知
mail:
#协议地址
host: smtp.163.com
#发送人邮箱
username:
#授权号 authpsd
password:
#发送人邮箱
formmailaddress:
#服务异常通知人邮箱,多个使用 , 分隔开
sendmailaddress:
日志记录
- route.startlog :true(开启),默认关闭,开启时需要初始化根目录下db文件夹内log_info.sql初始化
routelimit
-Gateway distributed current limiting implementation, based on redis+lua
-
- Based on redis token bucket form
-
- Current limit warning
-
- Asynchronous log link tracking
How to use
maven dependency
<dependency>
<groupId>com.github.sunywdev</groupId>
<artifactId>routelimit</artifactId>
<version>1.0.1</version>
</dependency>
Based on token bucket
@GetMapping("/logerror")
@Log(name = "Current Limit Test")
@RouteLimiter(acquiredQuantity = 1, burstCapacity = 2, repleniShrate = 1)
public Map<String, Object> logError() {
Map<String, Object> respMap = new HashMap<>();
respMap.put("code", "200");
respMap.put("msg", "success");
return respMap;
}
The number of tokens and the configuration of the token bucket
route:
#Number of tokens generated per second
replenishrate: 1
#Token capacity in bucket
burstcapacity: 10
#Get the number of tokens each time
acquiredquantity: 1
E-mail notification
mail:
#Protocol address
host: smtp.163.com
#Sender's mailbox
username:
#Authorization number authpsd
password:
#Sender's mailbox
formmailaddress:
#Service exception notification person mailbox, multiple uses, separate
sendmailaddress:
Logging
-route.startlog: true (open), closed by default, you need to initialize log_info.sql in the db folder under the root directory when it is turned on
