1. Dubbo related concepts 1.1 how automatic service discovery works

two。 Startup file

This refers to the use of zookeeper as a registry; and start relevant dubbo monitoring

2.1 zookeeper-3.4.11\ bin\ zkServer.cmd

You can configure the port number and data data of the zookeeper client under the zookeeper-3.4.11\ conf path:

Run cmd under the zookeeper-3.4.11\ bin directory to start the zookeeper service:

2.2 zookeeper-3.4.11\ bin\ zkCli.cmd

Run cmd under the zookeeper-3.4.11\ bin directory to start the zookeeper client:

2.3 java-jar dubbo-admin-0.0.1-SNAPSHOT.jar

You can modify the port of the DubboWeb interface in the application.properties file under the path incubator-dubbo-ops-master\ dubbo-admin\ src\ main\ resources:

Open the command line under the project root path, execute mvn clean package to package the project into jar, and then execute the java-jar dubbo-admin-0.0.1-SNAPSHOT.jar command to run Dubbo

2.4 dubbo-monitor-simple-2.0.0\ assembly.bin\ start.bat

You can configure the monitoring page port in the dubbo.properties file under the dubbo-monitor-simple-2.0.0\ conf path:

Double-click to run the start.bat file under the dubbo-monitor-simple-2.0.0\ assembly.bin path:

3. Modify the project file

Need to make some changes to the project file; to turn on dubbo related functions

3.1 Import related dependencies in the pom.xml file 2.6.2 org.apache.curator curator-framework 2.12.03.2 configure the dubbo3.2.1 provider in the application.properties file / src/main/resources/provider.xml file 3.2.2 consumers

When integrating Dubbo with SpringBoot, the above information can be configured in the application.properties file. For more information, please see "three ways to integrate SpringBoot with Dubbo".

3.3.Use the annotation enable function annotated location function @ EnableDubbo to enable dubbo related functions the main launch class @ Service exposes the service provider provider@Reference to remotely invoke the service consumer consumer4. Configuration file

Dubbo's XML Schema configuration reference manual

Dubbo:consumer configuration

4.1 priority of the profile

JVM startup-D parameter first

XML takes second place.

Finally, Properties is equivalent to the default

4.2 coverage relationships with different granularity configurations

The higher the priority, the higher the priority.

Precision priority (method level first, interface level second, global configuration second)

Consumer setting priority (if the level is the same, the consumer takes priority, followed by the provider)

4.3 turn off startup check check

The provider has three configurations for shutting down the startup check registry:

Spring profile

Dubbo.properties

Dubbo.reference.com.foo.BarService.check=falsedubbo.reference.check=falsedubbo.consumer.check=falsedubbo.registry.check=false

Pass the-D parameter

Java-Ddubbo.reference.com.foo.BarService.check=falsejava-Ddubbo.reference.check=falsejava-Ddubbo.consumer.check=false java-Ddubbo.registry.check=false

Consumers have a configuration to turn off the startup check service provider:

4.4 timeout timeout
