Hello, I encountered an issue. The details of the application.properties configuration are as follows:

Application service WEB access port

server.port=8090
spring.application.name=microsoftEmail

Motan protocol configuration

motan.protocol.name=motan
motan.protocol.default=motan
motan.registry.default=zookeeper
motan.service.interface=com.example.microsoftemail.rpc.motan.MotanMicrosoftEmailService
motan.service.ref=MotanMicrosoftEmailServiceImpl
motan.protocol.maxContentLength=1048576

Zookeeper registry center configuration

motan.registry.name=motanRegistry

motan.service.group=default_rpc_microsoftEmail
motan.service.accessLog=false
motan.service.shareChannel=true

motan.service.registry=motanRegistry

The code details are as follows:

package com.example.microsoftemail.config;

import com.weibo.api.motan.config.springsupport.AnnotationBean;
import com.weibo.api.motan.config.springsupport.BasicServiceConfigBean;
import com.weibo.api.motan.config.springsupport.ProtocolConfigBean;
import com.weibo.api.motan.config.springsupport.RegistryConfigBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@configuration
public class MotanConfig {

@Bean
public AnnotationBean motanAnnotationBean() {
    AnnotationBean motanAnnotationBean = new AnnotationBean();
    motanAnnotationBean.setPackage("com.example.microsoftemail.rpc");
    return motanAnnotationBean;
}

@Bean(name = "motan")
public ProtocolConfigBean protocolConfig() {
    ProtocolConfigBean config = new ProtocolConfigBean();
    config.setName("motan");
    config.setMaxWorkerThread(50);
    config.setMinWorkerThread(20);
    config.setFilter("statistic");
    config.setMaxContentLength(1048576);
    return config;
}

@Bean(name = "motanRegistry")
public RegistryConfigBean registryConfig() {
    RegistryConfigBean config = new RegistryConfigBean();
    config.setConnectTimeout(3000);
    config.setRequestTimeout(1000);
    config.setName("motanRegistry");
    config.setAddress("127.0.0.1:2181");
    config.setRegProtocol("zookeeper");
    return config;
}

@Bean
public BasicServiceConfigBean basicServiceConfig() {
    BasicServiceConfigBean config = new BasicServiceConfigBean();
    config.setExport("motan:9988");
    config.setGroup("default_rpc_microsoftEmail");
    config.setRegistry("motanRegistry");
    return config;
}

}

public interface MotanMicrosoftEmailService {
String hello(String name);
}

@MotanService
public class MotanMicrosoftEmailServiceImpl implements MotanMicrosoftEmailService {

@Override
public String hello(String name) {
    LoggerUtil.info("HelloServiceImpl is called, parameter: " + name);
    return "Hello " + name + "!";
}

}

@SpringBootApplication
@componentscan(basePackages = { "com.example" })
public class MicrosoftEmailApplication {

public static void main(String[] args) {
    SpringApplication.run(MicrosoftEmailApplication.class, args);
    MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
}

}
But the code starts with an error.

Please help me identify the issue. I have already tried changing the dependency versions, but the error still occurs.

com.weibo.api.motan.transport.EndpointFactory: get extension fail. extension name 'motan' not found means the EndpointFactory SPI extension named "motan" was not found.
You can check whether the dependency of the "motan-transport-netty" or "motan-transport-netty4" module is introduced in the pom. These two modules can only depend on one of them.

I have already added the motan-transport-netty dependency. Then, I tried switching from motan-transport-netty to motan-transport-netty4, and the application successfully started. After that, when I switched back from motan-transport-netty4 to motan-transport-netty, it was also successful. Before switching, I checked whether my dependencies were loaded, and they were indeed loaded. However, I kept encountering the aforementioned issue yesterday.
