参考这个例子 https://github.com/JoeCao/JsonRpcDemo

shevawen commented 9 years ago

@JoeCao 您给的例子是个provider，我发的错误是consumer端的

wuwen5 commented 9 years ago

@shevawen java端的consumer 也是一样的，可以发下你consumer的配置，检查是否引入dubbo-rpc-jsonrpc 包，你发的错误应该是没有引入dubbo-rpc-jsonrpc包，所以没有找到扩展的jsonrpc协议实现

服务端是否暴露了jsonrpc协议? 另外想提下，既然都是java之间交互为什么要使用jsonrpc呢？ 建议走dubbo协议，jsonrpc主要是为了支持跨语言之间的rpc调用。

shevawen commented 9 years ago

1、服务端是暴露了的curl测试了的

curl -i -H 'content-type: application/json' -X POST -d '{"jsonrpc": "2.0", "method": "dailyCountGroupByProvince", "params": [ "Nat", true, "2015-01-01","2015-05-01"],"id":1}' 'http://192.168.5.110:8080/assessment-web/assessment.service.count.CountService'

2、同一个service可能同时java和其他语言一起调用，如果不使用多协议提供服务的话，就有java调用jsonrpc情况了

wuwen5 commented 9 years ago

@shevawen 确实是个bug，已修复。

你之前的方式也可以指定dubbo协议

<dubbo:reference id="mergeService" interface="org.cimiss.wind_uv_merge.MergeService" timeout="30000" protocol="dubbo"/>

    <dubbo:reference id="countService" interface="assessment.service.count.CountService" timeout="30000" protocol="dubbo"/>

哈哈，赞

@wuwen5 昨天测试通过是因为有其他节点(HTTP协议发布的)，今天关掉那个节点，还是有问题的说，多贴一些堆栈信息

@shevawen 出错的这个消费节点是没有导入dubbo-rpc-jsonrpc包的吧？

wuwen5 commented 9 years ago

服务端暴露多协议建议配置default协议，default协议为dubbo协议

<dubbo:provider> default   boolean 可选 false 配置关联 是否为缺省协议，用于多协议 1.0.16以上版本
shevawen commented 9 years ago

确实导入了。按说jsonrpc应该是在supported protocol: [dubbo, http, injvm, mock, redis, registry, rmi, thrift]这个列表里的。稍晚，我上传一个demo。 本来想，我想看明白 http://blog.csdn.net/quhongwei_zhanqiu/article/details/41577235 之后再问的，但是还没。

shevawen commented 9 years ago

做了个demo，发现没问题了 :relaxed:
