限流例子:
// 测试方法
public String test1(){
this.initFlowQpsRule();
return "test";
}
// 限流规则
private void initFlowQpsRule() {
List<FlowRule> rules = new ArrayList<>();
FlowRule rule = new FlowRule(resourceName);
// set limit qps to 20
rule.setCount(20);
rule.setGrade(RuleConstant.FLOW_GRADE_QPS);
rule.setLimitApp("default");
rules.add(rule);
FlowRuleManager.loadRules(rules);
}
流控-规则
private void initFlowQpsRule() {
List<FlowRule> rules = new ArrayList<>();
FlowRule rule = new FlowRule(resourceName);
// set limit qps to 20
rule.setCount(20);
rule.setGrade(RuleConstant.FLOW_GRADE_QPS);
rule.setLimitApp("default");
rules.add(rule);
FlowRuleManager.loadRules(rules);
}
降级-规则
private void initDegradeRule() {
List<DegradeRule> rules = new ArrayList<>();
DegradeRule rule = new DegradeRule();
rule.setResource(KEY);
// set threshold RT, 10 ms
rule.setCount(10);
rule.setGrade(RuleConstant.DEGRADE_GRADE_RT);
rule.setTimeWindow(10);
rules.add(rule);
DegradeRuleManager.loadRules(rules);
}
热点-规则
ParamFlowRule rule = new ParamFlowRule(resourceName)
.setParamIdx(0)
.setCount(5);
// 针对 int 类型的参数 PARAM_B,单独设置限流 QPS 阈值为 10,而不是全局的阈值 5.
ParamFlowItem item = new ParamFlowItem().setObject(String.valueOf(PARAM_B))
.setClassType(int.class.getName())
.setCount(10);
rule.setParamFlowItemList(Collections.singletonList(item));
ParamFlowRuleManager.loadRules(Collections.singletonList(rule));
系统规则
private void initSystemRule() {
List<SystemRule> rules = new ArrayList<>();
SystemRule rule = new SystemRule();
rule.setHighestSystemLoad(10);
rules.add(rule);
SystemRuleManager.loadRules(rules);
}
授权规则
AuthorityRule rule = new AuthorityRule();
rule.setResource("test");
rule.setStrategy(RuleConstant.AUTHORITY_WHITE);
rule.setLimitApp("appA,appB");
AuthorityRuleManager.loadRules(Collections.singletonList(rule));
