dubbo-proxy's Issues

Not support multi address to register

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'nettyServer': Unsatisfied dependency expressed through field 'registry'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getRegistry' defined in class path resource [org/apache/dubbo/proxy/Config.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.alibaba.dubbo.registry.Registry]: Factory method 'getRegistry' threw exception; nested exception is java.lang.NumberFormatException: For input string: "2181,xxx:2181,xxx:2181"

dubbo group not set for reference

From your code ,we can see even if this registry has group but not set for registeryConfig

public static void init() {
        RegistryConfig registryConfig = new RegistryConfig();
        registryConfig.setAddress(registry.getUrl().getProtocol() + "://" + registry.getUrl().getAddress());
     
        applicationConfig = new ApplicationConfig();
        applicationConfig.setName("dubbo-proxy");
        applicationConfig.setRegistry(registryConfig);
    }

As we know , dubbo registry stands for path in zookeeper. The default path is dubbo.
At this point , we should set the group to avoid "not provider " message

在当前master（2.7.5-snapshot）分支中demo模块启动失败,请关注AbstractInterfaceConfig该类实现

https://github.com/apache/dubbo/blob/master/dubbo-config/dubbo-config-api/src/main/java/org/apache/dubbo/config/AbstractInterfaceConfig.java

对比2.7.4中release代码发现当前master（2.7.5-snapshot）存在bug，
`

           ConfigManager configManager = ConfigManager.getInstance();
            ConfigCenterConfig cc = (ConfigCenterConfig)configManager.getConfigCenter().orElse(new ConfigCenterConfig());
            if (rc.getParameters() != null) {
                Map<String, String> configParams = cc.getParameters() == null ? new HashMap() : cc.getParameters();
                ((Map)configParams).putAll(rc.getParameters());
                cc.setParameters((Map)configParams);
            } 
            cc.getParameters().put("client", rc.getClient());

rc.getParameters()为空的情况下cc.getParameters()为空，导致 cc.getParameters().put("client", rc.getClient());抛空指针

你跑过吗

dubbo 2.6.3 is support ?

dubbo注册之后，发现org.springframework.aop.SpringProxy被注册到里面了，有人知道怎么回事吗

dubbo 有自带的cache版的ReferenceConfig不需要Map做缓存

Dubbo proxy sometimes cannot response directly

sometimes netty chanlle not close without keepalive header

update dubbo version

But we fixed in this pr apache/dubbo#4612

We need dubbo-proxy can handle with form post or queryString

dubbo-proxy should consider about how to be a gateway~
If only json is accepted , we should pass through the json string from user.
It's not user-friendly.

项目启起来了，但调不通？

dubbo提供了rest功能，为什么不使用这个对外提供接口？

多个注册中心怎么处理？

一个提问,我看源码中根据Parmatypes.length加上方法名去判断是哪个元数据,不会出现重载的方法调用不到的情况吗

dubbo GenericInvoke throws exception local class incompatible

apache/dubbo#4675
since dubbo may not release as soon as possible.
Maybe we should support dubbo 2.6.x or something else?

Not support dubbo attachments

We need dubbo attachments support~

能支持nacos吗

support nacos？

文件接口如何处理？

@qixiaobo 大佬这个东西还维护嘛?

如果方法有泛型参数的话，调用报错。是不是还不支持泛型参数啊？

错误：
java.lang.ClassCastException: com.alibaba.fastjson.JSONObject cannot be cast to com.example.dto.MedicationAddReq

不能指定tomcat的端口吗

We need handle with some error scenes

Some scenes we will make some mistakes.
In this scenario, we shoud fail fast nor hang for a keep-alive time out.

dubbo-proxy应当增加安全访问机制，避免内部服务全通

如标题，需要加强的安全机制包括两方面：
1、dubbo-proxy对内部服务的访问应当加以控制（安全策略配置），避免所有内部服务全通
2、增加对接口参数校验、IP黑白名单等初级到高级的安全策略
