最近花了一些时间，看了一下OpenResty的东西，感觉用来做API网关的确很赞：

Spring Boot各模块作用
1、spring-boot
web容器整合，快速开发，上下文、外部配置、日志的统一管理
2、spring-boot-autoconfigure
自动配置，自动判断需要的jar包
3、spring-boot-actuator
生产环境管理，用rest方式给出多种接口：
mappings/autoconfig/configprops/beans
env/info/health/heapdump/metrics
loggers/logfile/dump/trace
shutdown/auditevents
4、spring-boot-starters
各种配置好的功能模块，用于快速拼装各种需要的功能
5、spring-boot-loader
用于加载jar包中的jar，可以实现单个jar/war的运行
注意：这种jar包放到jar包时，不要再次压缩
6、spring-boot-cli
快速开发groovy
7、spring-boot-devtools
方便调试，远程调试
Spring Boot Cli入门
1、test.groovy
@RestController
class testApp{
@RequestMapping("/")
String home() {
"It works!"
}
}
2、运行
bin/spring run test.groovy
3、这样，一个spring boot的网站已经开启了哦
Spring Cloud Sleuth入门
1、下载并运行zipkin
https://github.com/openzipkin/docker-zipkin
sudo ./docker-compose up
2、运行示例程序，并触发对应方法
spring-cloud-sleuth-sample-zipkin（需要Zipkin） 或者 spring-cloud-sleuth-sample-stream（需要RabbitMQ+Zipkin）
3、查看运行情况
http://localhost:9411

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

}
@RequestMapping("/invokeC/{clientName}")
String invokeC(@PathVariable("clientName") String clientName)
{

}
//@Override

};
}
}
}
2、MyFeignClientConfiguration
package com.neohope.springcloud.test;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import feign.Logger;
import feign.auth.BasicAuthRequestInterceptor;
@Configuration
public class MyFeignClientConfiguration {
@Bean
public BasicAuthRequestInterceptor basicAuthRequestInterceptor() {
return new BasicAuthRequestInterceptor("user", "hystrix");
}
/*
@Bean
Logger.Level feignLoggerLevel() {
return Logger.Level.FULL;
}
*/
}

Spring Cloud Netflix入门（Sidecar）
SideCar主要是用于将非JVM语言的服务，代理为Netflix服务
1、SideCarApp
package com.neohope.springcloud.test;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.sidecar.EnableSidecar;
import org.springframework.web.bind.annotation.RequestMapping;
//作用一、注册到eureka并提供服务健康状态
//其他语言的服务，首先服务封装为REST或JSON通信，并提供一个health路径，反馈服务是否正常
//sidecar会将这个服务注册到eureka
//其他服务，可以通过eureka查询并调用该服务
//作用二、从sidecar获取服务地址，并调用
//访问sidecar，获取服务地址 http://localhost:port/hosts/{serviceId}.
//分析返回结果，得到服务地址
//调用需要的服务
@EnableSidecar
public class SideCarApp
{
@Value("${spring.application.name}")
private String appName;
@RequestMapping("/appName")
public String appName() {
return appName;
}
