Spring Cloud Gateway集成Sentinel，限流

1、添加依赖

		<dependency>
			<groupId>com.alibaba.csp</groupId>
			<artifactId>sentinel-core</artifactId>
			<version>1.6.3</version>
		</dependency>
		<dependency>
			<groupId>com.alibaba.csp</groupId>
			<artifactId>sentinel-spring-cloud-gateway-adapter</artifactId>
			<version>1.6.3</version>
		</dependency>
		<dependency>
			<groupId>com.alibaba.csp</groupId>
			<artifactId>sentinel-transport-simple-http</artifactId>
			<version>1.6.3</version>
		</dependency>

添加限流规则，设置限流参数

//设置API
Set<ApiDefinition> definitions = new HashSet<>();
ApiDefinition api1 = new ApiDefinition("account_api")
        .setPredicateItems(new HashSet<ApiPredicateItem>() {
  {
            add(new ApiPathPredicateItem().setPattern("/api/v1/account/**")
                    .setMatchStrategy(SentinelGatewayConstants.URL_MATCH_STRATEGY_PREFIX));
        }});


//设置规则
rules.add(new GatewayFlowRule("userplatform")
        .setCount(2)
        .setIntervalSec(1)
);

rules.add(new GatewayFlowRule("account_api")
        .setResourceMode(SentinelGateway
