I am running the dubbo-demo-spring-mvc-rest-provider project in dubbo repository on branch 3.3. And some errors happens like below:

java.lang.IllegalStateException: No such extension org.apache.dubbo.rpc.Protocol by name rest, no related exception was found, please check whether related SPI module is missing.

I know this error is because of rest protocol is moved to dubbo-spi-extensions respository. So I add dependency of dubbo-rpc-rest in the pom.xml of dubbo-demo-spring-mvc-rest-provider project.

<dependency>
      <groupId>org.apache.dubbo</groupId>
      <artifactId>dubbo-rpc-rest</artifactId>
      <version>3.3.0-beta.2</version>
</dependency>

After that, I run the dubbo-demo-spring-mvc-rest-provider project again and I get an another error like below:

I search this problem in this forum and google. However, I do not find any solutions. Is there any one know how to run this dubbo-demo-spring-mvc-rest-provider project? Thank you for your help!

I have known the problem is why.

If my macbook is connected to a WiFi, my macbook will have a new Ip address, just like 7.250.138.200. This Ip is allocated by the WiFi, and my macbook can visit the Internet throught this Ip. However, the other cannot visit my macbook through this Ip.

When my macbook is connected to the WiFi, the dubbo rest provider will be exposed to the 127.0.0.1, but in the registory center, the Ip is 7.250.138.200. So we can visit the 127.0.0.1 to call the rest provider through http request and cannot visit the 7.250.138.200 to call the rest provider through dubbo rest consumer. As long as I close my WiFi, the dubbo rest consumer can do rpc to call the dubbo rest prov…

You should import https://github.com/apache/dubbo-spi-extensions/tree/master/dubbo-rpc-extensions/dubbo-rpc-rest instead of the old version of the package

Check the groupId

I have found the problem is that I need to checkout dubbo repository to dubbo-3.3.0-beta.2 tag. After I checkout the correct tag, I have run the demo with no error, but the consumer cannot call the provider correctly.

The above get method will timeout after a long time gap. I am exploring this new problem.

Thanks to your reply.

Try

<dependency>
    <groupId>org.apache.dubbo.extensions</groupId>
    <artifactId>dubbo-rpc-rest</artifactId>
    <version>3.3.0</version>
</dependency>

3.3.0 is not existed in maven repository

3.3.0 is not existed in maven repository

Have you do a try?
I can download in https://repo1.maven.org/maven2/org/apache/dubbo/extensions/dubbo-rpc-rest/3.3.0/

groupId is:

org.apache.dubbo.extensions

emmm... I have tried the package you mentioned, the result is same as this below package.

<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-rpc-rest</artifactId>
    <version>3.3.0-beta.2</version>
</dependency>

The consumer rpc call will timeout. And the producer seems do not receive a rpc call, I am solving this problem like below error message.

I have searched many dubbo rest rpc call demos, but I do not find a one can be run successfully. I can call dubbo provider by http urls, but I cannot call it by dubbo consumer. And I do not have a idea about how to solve this problem, what I find is consumer timeout and it seems that the provider do not receive a remote call.

I have known the problem is why.

If my macbook is connected to a WiFi, my macbook will have a new Ip address, just like 7.250.138.200. This Ip is allocated by the WiFi, and my macbook can visit the Internet throught this Ip. However, the other cannot visit my macbook through this Ip.

When my macbook is connected to the WiFi, the dubbo rest provider will be exposed to the 127.0.0.1, but in the registory center, the Ip is 7.250.138.200. So we can visit the 127.0.0.1 to call the rest provider through http request and cannot visit the 7.250.138.200 to call the rest provider through dubbo rest consumer. As long as I close my WiFi, the dubbo rest consumer can do rpc to call the dubbo rest provider.

If you plan to use dubbo 3.3, it is recommended to use the new triple rest:
