consumer 在某些情况下会抛出Dubbo client can not supported string message异常,并且 message 显示为乱码信息,经查找资料是说消息体 >8M 导致; 实际测试结果: 我本地测试的时候,均无法复现对应的异常信息,>8M 的表现为 consumer 等待超时,且 provider 抛出Data length too large:异常。

服务端有数据返回时,回调用NettyClientHandler.channelRead()方法。 开始调用Handler的执行链。 HeartbeatHandler:发送心跳应答 AllChannelHandler:服务隔离思想,获取线程池异步执行 DecodeHandler:编解码,Hession进行反序列化 HeaderExchangeHandler: 服务端: 双工通信:处理请求,调用Filter执行链,最终调用Service方法。并将结果...

由于Dubbo是基于Spring的自定义扩展标签来实现配置的,而发布服务时我们需要配置dubbo:service标签,因此我们可以从这里入手。 首先我们需要知道Spring的自定义扩展标签由xsd后缀的文件及spring.schemas(自定义标签)、spring.handlers及DubboNamespaceHandler(NamespaceHandler注册标签的命名空间,这个文件和类类似SPI机制)、以及...
