Background

As the main means of back-end service load and front-end separation, dubbo has a relatively high utilization rate in the industry. With the increase of Dubbo system, there is trouble in local development and debugging.

Directly start the same service locally in the developer

Because Dubbo adopts the strategy of load balancer, it always goes to the local service at random in the case of multiple requests, which is somewhat life-saving.

Modify Group

As a sub-Group strategy supported by Dubbo, it is feasible to register individual developers to a Gruop independently. This requires simultaneous changes on the consumer side and the provider side, which is a bit of a hassle.

And you will want to register a list of services in the registry.

Directly connected

Direct connection means that the service is not registered with the registry to prevent Dubbo requests from the test environment from being assigned to the local development server.

1. Modify the service provider configuration file

Among them, register= "false" is the main configuration that works. What he means is that if you start the service locally, you do not want to register the service in the registry.

This block will be configured in filter later. Dev. properties defaults to false,test without true by default. Deploy the configuration file of test in the test environment later

2. Add the default directly connected profile

The ${user.home} / dubbo-resolve.properties file is automatically loaded in version 2.0 and no configuration is required.

${user.home} refers to the current operating system user directory, for example, the user directory of Win7 system Administrator is C:\ Users\ Administrator

Mac is / Users/luoaz or something.

The configuration is as follows

Com.ai.trial.modules.trial.service.TlAccusedProcessService=dubbo://localhost:21006com.ai.trial.modules.trial.service.TlProcessService=dubbo://localhost:21006

Through the above configuration, the specified service will not be found in the registry, but directly request the configuration path, dubbo://localhost:21006, and then go to the configuration center for other unconfigured services.

This makes it easy to debug.

Ps: if you are lazy and easy, you can declare all the services, so you don't have to worry about it in the future.

The above Dubbo local development tips sharing is the editor to share with you all the content, I hope to give you a reference, but also hope that you support more.
