Sentinel实现限流
Sentinel的SPI提供了自定义限流规则的功能。您可以通过以下步骤来实现自定义限流规则:
1. 实现FlowRule接口,定义您的自定义限流规则,例如:
```java
public class CustomFlowRule implements FlowRule {
private String resourceName;
private int count;
public CustomFlowRule(String resourceName, int count) {
this.resourceName = resourceName;
this.count = count;
}
public String getResourceName() {
return resourceName;
}
public int getCount() {
return count;
}
}
```
2. 实现FlowRuleProvider接口,提供您的自定义限流规则,例如:
```java
public class CustomFlowRuleProvider implements FlowRuleProvider<CustomFlowRule> {
public List<CustomFlowRule> getRules() {
List<CustomFlowRule> rules = new ArrayList<CustomFlowRule>();
// 从配置中心或数据库中读取规则信息,构造CustomFlowRule对象
// ...
return rules;
}
}
```
3. 在Sentinel的初始化代码中注册您的自定义限流规则提供器,例如:
```java
FlowRuleManager.register2Property(new CustomFlowRuleProvider());
```
这样,您就可以通过您的自定义限流规则来对资源进行限流了。
