Dubbo test environment service call isolation. Is that right

dubbo test environment service isolation.


Background statement

the other day , A classmate asked me about Dubbo The problem of . His appeal is like this :

Appeal one

The first appeal is to call your own services when developing locally , For example, I'm changing A service , Then something went wrong , Start another one locally B service ,A The service call B Service direct troubleshooting .

The current problem is using the same registry , So it will call other service instances .

What's more, I found some articles on the Internet , According to the configuration on the data, there is no effect , That is to say @Reference To configure url To specify the calling service address .

The configuration is as follows :

  1. @Reference(url="dubbo://localhost:20880")

Appeal 2

At present, their test environment doesn't use Docker To deploy , And each service has only one instance deployed . The problem is that when a project is developed in parallel, there are multiple branches , These branches have to be combined to deploy tests together . There are often code conflicts and other issues .

And when it's about to go online , Need to drop other branches for regression testing . But there will be other teams coming online on the same day , We can only negotiate and wait to solve .

The best way is to deploy an instance in a branch , For their current scale and investment, they can't do it for the time being . So he asked me for advice , Is there a better and faster way .

Solution

Now that you've come to me , Let me give you some advice , Not necessarily good , For reference only .

Demand a solution

@Reference

stay @Reference It is specified in url Yes. , It's just that there is a problem with the address configured by that classmate , The interface and version information should be added after the address .

  1. @Reference(url="dubbo://localhost:20880/com.xxx.xxx:1.0")

Local profile

stay @Reference It is specified in url The bad way is to couple with the code , It's easy to submit this code . So we introduce another way .

Create one in your computer's user directory dubbo-resolve.properties file , The path is a \${user.home}/dubbo-resolve.properties , Then configure the service information that needs direct connection in the file , There is no need to modify other configuration information of the local project .

dubbo-resolve.properties

  1. com.xxx.xxx=dubbo://localhost:20880/com.xxx.xxx:1.0.0

com.xxx.xxx It's the full path of the interface , After the equal sign is the address of the service .

Claim two solution

Since it's not possible to retrofit the deployment system in a short period of time , Then we can simply deal with . At present, they share a test environment with two teams , I think we can add a new environment to isolate teams .

For the entrance Web Program or gateway , We can solve this problem with two domain names . The main reason is that internal service calls need to be isolated , For example, I A Team deployed services cannot let B The team calls to , Because different branches can cause problems .

Registration isolation

Registration isolation refers to registering the test services of the two teams separately at the time of service registration , For example, use a separate registry .

A separate registry can certainly solve the problem , But there's no need to be so bothered . Their registry uses Nacos, have access to Nacos Of namespace To isolate .

  1. -Ddubbo.registry.address=nacos://api.nacos.beta.xxx.com:8848?namespace=xxx

Local profile

You can also use the local configuration file to specify the service to be called , The premise of this approach is that the deployed machine is independent , Can't share . If a new interface is added, the configuration file needs to be modified .

control Dubbo Routing or load balancing

Control routing or load balancing is to achieve the same effect , That is to give you all the service provider information , You choose one of your own to call .

Official documents :

http://dubbo.apache.org/zh-cn/docs/dev/impls/router.html

http://dubbo.apache.org/zh-cn/docs/dev/impls/load-balance.html

summary

For the solution of claim one , It is recommended to use local configuration file . No need to change the code , It's more convenient .

For the solution of claim two , It is recommended to use registration isolation . This is the most thorough way , Using registration quarantine , You don't have to think of a way to control the routing , This is the environment I need to register , You don't need to register information in another namespace , Mutual indifference .
