jim-framework

分享部分工作中的内容，包含一些抽取出来的公共组件以及在spring boot下常用组件的应用。

代码会在后续陆续更新

公共组件

统一配置中心

• 统一配置中心1
• 统一配置中心2

RPC

Dubbo环境下基本请求级的缓存 （未同步代码）

• 变通实现微服务的per request以提高IO效率1
• 变通实现微服务的per request以提高IO效率2
• 变通实现微服务的per request以提高IO效率3

分布式调用链追踪

• dubbo+zipkin调用链监控
• dubbo+zipkin调用链监控(二)

自定义RPC框架:netty+consul

• 简易RPC框架-学习使用
• 简单RPC框架-基于Consul的服务注册与发现
• 简单RPC框架-业务线程池
• 简易RPC框架-私有协议栈
• 简易RPC框架-心跳与重连机制
• 简易RPC框架-过滤器机制
• 简易RPC框架-客户端限流配置
• 简易RPC框架-上下文
• 简易RPC框架-代理
• 简易RPC框架-熔断降级机制
• 简易RPC框架-SPI

熔断降级实现影响上下文机制，后续更新解决

基于注解的锁

Spring boot实践

WEB

• Validator （未同步代码） 多字段动态运算符
• HandlerMethodArgumentResolver （未同步代码） 接口参数注入

消息队列

• 从头开始搭建一个Spring boot+RabbitMQ环境
• 从头开始搭建一个Spring boot+ActiveMQ高可用分布式环境

Spring Cache+Redis

• Spring Cache扩展：注解失效时间+主动刷新缓存
• Spring Cache扩展：注解失效时间+主动刷新缓存(二)

面向对象 （未同步代码）

工作中的一些设计实践，合适不合适仁者见仁吧。

• 状态模式
• 职责键模式，同事设计的处理复杂订单流程。
• 建造者，策略模式。新旧价格转换过程中的尝试。

jim-framework's Issues

cache这个项目可以用在生产吗？

请问下稳定吗？

请问那个链路追踪的demo跑哪一个工程啊？

[提议]dubbo zipkin扩展实现进入dubbo生态

@jiangmin168168 我们是Apache Dubbo(incubating)的社区开发，我们非常希望你的zipkin-dubbo能进入dubbo生态（github.com/dubbo)，未来一起把dubbo社区和生态做大。期待你的答复！

TraceContext.getTraceConfig()为null是什么情况？

我的环境:springboot2.0+dubbo2.6
项目结构和你的差不多，也是提供者和消费者分别引入com.jim.framework.dubbo.core
启动的时候加载时traceConfig不为null
@PostConstruct
public void init() throws Exception {
TraceContext.init(this.traceConfig);
}
DEBUG的时候TraceConsumerFilter类的TraceContext.getTraceConfig()获取为null，找不到原因

你好，如果是feign+dubbo的话，怎么监控呢？

jim-framework-rpc-consumer引不到jim-framework-rpc和jim-framework-rpc-api的类

jim-framework-rpc和jim-framework-rpc-api已经构建成功，本地仓库也已经有了jar包
但构建jim-framework-rpc-consumer和jim-framework-rpc-provider的时候就是引不到上面两个模块的类，是打开姿势有什么不正确嘛....求解答

这个demo反应太慢了，需要1.06s的响应时间？这个正常吗？还是filter写的有问题？

zipkin-dubbo可以用dubbo2.6版本么？

rt

博主，你的文章质量还不错，怎么不继续更新了？

请教下项目如何构建

根目录下（parent 项目）执行 mvn clean install 报错，请问是我构建的方式不对吗？

关于异步调用

楼主你们生产的项目，用dubbo的异步调用多么，我们全部都是同步调用
另外dubbo现在支持的异步调用并不完善，还有些坑 比方 A -> B 是异步 B的处理过程里本来是同步调的C，然鹅因为 A调B的时候在context里设置了异步的标志，导致B调C也变成了异步，然后会取不到结果
