soul从入门到进阶06——运行soul-examples-dubbo

本文主要是介绍soul从入门到进阶06——运行soul-examples-dubbo，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前面我们初步尝试了soul网关的http协议相关的功能。这篇我们来看一下 dubbo协议的功能。

1. 启动soul-admin 和 soul-bootstrap

省略 可参考 soul从入门到进阶01——soul网关初体验

2. 启动 soul-example-dubbo

1. 打开命令行
2. cd soul-examples
3. cd soul-examples-dubbo

可以看到分别是apache dubboe的example和 alibaba dubbo的example

4. 进入 soul-examples-apache-dubbo-service 这个模块
5. 运行 TestApacheDubboApplication
6. 发现报错了,显示zookeeper 没有连接
7. 下载一个zookeeper ,注意 如果是初次使用，需要将conf文件夹下的zoo_sample.cfg 复制为名为zoo.cfg的文件，否则会报以下错误。

pache-zookeeper-3.6.2-bin/bin/../conf/zoo.cfg: No such file or directory

8. 此时再次启动 TestApacheDubboApplication

3 查看soul-admin

1. 如下图所示，dubbo这个插件里多了一个选择器。选择器里面有很多规则。

4. 通过http访问dubbo

1. 在 postman 请求http://localhost:9195/dubbo/findAll

{"code": 200,"message": "Access to success!","data": {"name": "hello world Soul Apache, findAll","id": "-275502741"}
}

2. 发现bootstrap 打印了如下日志

2021-01-21 00:13:35.517  INFO 23633 --- [-work-threads-1] o.d.soul.plugin.base.AbstractSoulPlugin  : dubbo selector success match , selector name :/dubbo
2021-01-21 00:13:35.518  INFO 23633 --- [-work-threads-1] o.d.soul.plugin.base.AbstractSoulPlugin  : dubbo selector success match , selector name :/dubbo/findAll

5. 修改规则

1. 在soul-admin 将 【dubbo插件】——【dubbo选择器】——【/dubbo/findAll 规则】关闭。
2. 再次请求 http://localhost:9195/dubbo/findAll
3. 响应结果如下 ，没有这条规则，就不能访问

{"code": -102,"message": "Rule not found!","data": null
}

6. 压测一下

wrk -t16 -c200 -d30s  http://localhost:9195/dubbo/findAll

Running 30s test @ http://localhost:9195/dubbo/findAll16 threads and 200 connectionsThread Stats   Avg      Stdev     Max   +/- StdevLatency    17.82ms   24.68ms 498.22ms   93.66%Req/Sec   829.79    268.27     1.51k    69.90%379644 requests in 30.09s, 66.61MB readSocket errors: connect 0, read 157, write 0, timeout 0

Requests/sec:  11298.65
Transfer/sec:      1.98MB

发现qps在1.2w左右。
采用 压测soul网关 中的办法 将soul-bootstrap 的日志级别调整为warn再次压测

结果如下

Running 30s test @ http://localhost:9195/dubbo/findAll16 threads and 200 connectionsThread Stats   Avg      Stdev     Max   +/- StdevLatency    15.63ms   21.21ms 391.96ms   91.58%Req/Sec     0.96k   275.19     1.86k    72.45%453131 requests in 30.04s, 79.51MB readSocket errors: connect 0, read 167, write 0, timeout 0
Requests/sec:  15082.54
Transfer/sec:      2.65MB

Requests/sec:  21376.63
Transfer/sec:      3.75MB

Running 30s test @ http://localhost:9195/dubbo/findAll16 threads and 200 connectionsThread Stats   Avg      Stdev     Max   +/- StdevLatency    20.25ms   27.69ms 136.29ms   83.67%Req/Sec     1.32k   263.94     2.43k    69.90%630119 requests in 30.02s, 110.56MB readSocket errors: connect 0, read 51, write 0, timeout 0
Requests/sec:  20987.25
Transfer/sec:      3.68MB

性能明显提升了，可以达到2w的qps
