Spring Cloud Netflix入门（Turbine）

Posted on by — No Comments ↓

Turbine是一个日志收集器，用于聚合Hystrix中的日志。

1、TurbineServer

package com.neohope.springcloud.test;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.stream.EnableTurbineStream;
import org.springframework.web.bind.annotation.RequestMapping;

@SpringBootApplication
@EnableCircuitBreaker
@EnableEurekaServer
@EnableHystrixDashboard
@EnableTurbineStream
public class TurbineServer 
{
	@Value("${spring.application.name}")
	private String appName;
	
	@RequestMapping("/appName")
	public String appName() {
		return appName;
	}
	
	public static void main(String[] args) {
        new SpringApplicationBuilder(TurbineServer.class).web(true).run(args);
    }
}

2、pom.xml
