最近发现了一个新的开源项目:SOFABoot,再加上公司用的框架也是SOFABoot,所以给将这个框架分享给大家,希望能扩展大家的视野。

首先我们需要知道什么是SOFABoot?

SOFABoot 是蚂蚁集团开源的基于 Spring Boot 的研发框架,它在 Spring Boot 的基础上,提供了诸如 Readiness Check,类隔离,日志空间隔离等等能力。

下面是他的项目地址:

https://gitee.com/sofastack/sofa-boot

为什么要选择SOFABoot?他能解决什么问题?

根据官方介绍,他主要能解决以下的问题:

  1. Spring Boot 的健康检查只有 Liveness Check 的能力,缺少 Readiness Check 的能力

这里给大家科普一下Liveness CheckReadiness Check 是什么东西

Liveness Check 和 Readiness Check 概念来自于 Kuberentes,分别代表运行时检查和启动时检查。 利用 Readiness Check 的能力,SOFA 中间件中的各个组件只有在 Readiness Check 通过之后,才将流量引入到应用的实例中,比如 RPC,只有在 Readiness Check 通过之后,才会向服务注册中心注册,后面来自上游应用的流量才会进入

  1. 提供模块化开发的能力

基于 Spring 上下文隔离提供模块化开发能力,每个 SOFABoot 模块使用独立的 Spring 上下文,避免不同 SOFABoot 模块间的 BeanId 冲突

  1. 增加日志空间隔离的能力

在超大规模微服务运维的场景下,运维能力的平台化是一定要解决的问题,而监控又是其中非常主要的一个点,针对于日志监控这种情况,Spring Boot 并没有提供任何解决方案。大部分的开源组件,具体要打印哪些日志,打印到什么路径,什么文件下面,都是由应用的使用者来决定,这样会导致每一个应用的日志配置都各式各样,每一个应用都需要去监控系统中配置自己应用的日志监控,导致关键的监控的实施成本特别高

中间件框架自动发现应用的日志实现依赖并独立打印日志,避免中间件和应用日志实现绑定,通过 sofa-common-tools 实现

  1. 增加类隔离的能力

基于 SOFAArk 框架提供类隔离能力,方便使用者解决各种类冲突问题

为了解决以上的问题,又因为 SOFA 中间件中的各个组件本身就需要集成 Spring Boot,所以蚂蚁集团基于 Spring Boot 开发并开源了 SOFABoot,来解决以上的问题,也方便使用者在 Spring Boot 中方便地去使用 SOFA 中间件。

以上都是官方给出的解释。

那么我们怎样快速搭建一个SOFABoot工程呢?

第一步

创建一个springboot项目 在这里插入图片描述

第二步,替换pom.xml中的以下内容:

在这里插入图片描述 第三步,添加healthcheckweb

这步非常重要添加之前控制台启动依旧是打印spring 在这里插入图片描述 而且没有健康检查的机制,添加之后我们再看控制台打印 在这里插入图片描述 直到现在,我们的SOFABoot项目就搭建完成了,非常简单, 我们也可以查看当前项目的健康状况:

在这里插入图片描述

好了,今天先分享到这里,大家已经快速入门了一波,后面我会继续带大家走入SOFABoot的世界,欢迎大家关注一波!!

上次我们介绍了sofaboot:

https://blog.csdn.net/csdnerM/article/details/124750460

这次我们来介绍SOFAStack家族中的SOFARPC 在这里插入图片描述 首先我们知道了sofaboot是在Spring Boot 的基础上,提供了诸如 Readiness Check,类隔离,日志空间隔离等等能力。

那么,sofarpc又是什么呢?

SOFARPC 是蚂蚁金服开源的一款基于 Java 实现的 RPC 服务框架,为应用之间提供远程服务调用能力,SOFARPC 是一个高可扩展性、高性能、生产级的 Java RPC 框架。

在这里插入图片描述 下面是它的开源仓库地址:

https://gitee.com/sofastack/sofa-rpc

sofarpc的原理是什么?

在这里插入图片描述

1.当一个 SOFARPC 的应用启动的时候,如果发现当前应用需要发布 RPC 服务的话,那么 SOFARPC 会将这些服务注册到服务注册中心上。如图中 Service 指向 Registry。 2.当引用这个服务的 SOFARPC 应用启动时,会从服务注册中心订阅到相应服务的元数据信息。服务注册中心收到订阅请求后,会将发布方的元数据列表实时推送给服务引用方。如图中 Registry 指向 Reference。 3.当服务引用方拿到地址以后,就可以从中选取地址发起调用了。如图中 Reference 指向 Service。

熟悉springcloud的同学是不是觉得它和eurekafegin之间的关系特别像?

我们来开始他的快速使用

大家也可以拉我仓库的代码下载起来直接启动:

https://gitee.com/WangFuGui-Ma/sofastack-quickstart

我们是按照sofaboot的方式进行框架的快速启动 所以如果不知道sofaboot怎么启动的话请查看我的上篇文章sofaboot的快速入门

https://blog.csdn.net/csdnerM/article/details/124750460

第一步,引入 RPC Starter:

        <dependency>
            <groupId>com.alipay.sofa</groupId>
            <artifactId>rpc-sofa-boot-starter</artifactId>
        </dependency>
        

在这里插入图片描述 第二步,编写xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sofa="http://sofastack.io/schema/sofaboot"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://sofastack.io/schema/sofaboot   http://sofastack.io/schema/sofaboot.xsd"
       default-autowire="byName">

</beans>

在这里插入图片描述

第三步,定义服务接口与实现

public interface HelloSyncService {

    String saySync(String string);
}
public class HelloSyncServiceImpl implements HelloSyncService {

    @Override
    public String saySync(String string) {
        return string;
    }
}

在这里插入图片描述 在这里插入图片描述 第四步,服务端发布服务

在 xml 文件中编写如下配置。Spring 上下文在刷新时,SOFABoot 就将该服务实现注册到了服务器上,以 bolt 协议与客户端进行通信地址,并将地址等元数据发布到了注册中心(这里默认使用的本地文件作为注册中心)。


    <bean id="helloSyncServiceImpl" class="com.masiyi.sofaboot.HelloSyncServiceImpl"/>
    <sofa:service ref="helloSyncServiceImpl" interface="com.masiyi.sofaboot.HelloSyncService">
        <sofa:binding.bolt/>
    </sofa:service>

在这里插入图片描述 第四步,客户端引用服务

在 xml 文件中编写如下配置。Spring 上下文刷新时,SOFABoot 会生成一个RPC的代理 bean,即 personReferenceBolt 。这样就可以直接在代码中使用该 bean 进行远程调用了。

    <sofa:reference id="helloSyncServiceReference" interface="com.masiyi.sofaboot.HelloSyncService">
        <sofa:binding.bolt/>
    </sofa:reference>

在这里插入图片描述 第五步,运行

在 SpringBoot 的启动类中编码如下。其中利用 ImportResource 将上述的xml文件加载。


@ImportResource({ "classpath*:rpc-sofa-boot-starter-samples.xml" })
@SpringBootApplication
public class SofabootApplication {

    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(SofabootApplication.class);
        ApplicationContext applicationContext = springApplication.run(args);

        HelloSyncService helloSyncServiceReference = (HelloSyncService) applicationContext
                .getBean("helloSyncServiceReference");

        System.out.println(helloSyncServiceReference.saySync("hello , 王富贵"));
    }

}

在这里插入图片描述 这样就可以在容器中拿到服务类并且进行访问了

控制台输入打印: 在这里插入图片描述 到此,一个sofarpc的快速启动就已经成功完成了!!
