1.問題
A項目在dev環(huán)境打版，可以順利調(diào)用B項目的dubbo服務。但是我在本地環(huán)境定點連dev環(huán)境B項目的dubbo服務，連接不上。接口沒有修改，之前是可以調(diào)通，突然不可以了.
2.代碼
dubbo接口如下：
PaginationSupport findPageClassesList(ClassTeacherVo vo,Integer pageNo,Integer pageSize,String order);調(diào)用示例如下:
PaginationSupport findPageClasses = iClassRpcService().findPageClassesList(tempVo, 1, 10, "createTime");3.報錯
為了防止有人惡意攻擊，把服務ip改成10.0.0.0
com.alibaba.dubbo.rpc.RpcException: Failed to invoke remote method: findPageClassesList, provider: dubbo://10.0.0.0:20881/com.bbtree.school.api.interfaces.IClassRpcService?application=bbtree-erp&default.check=false&default.loadbalance=leastactive&default.reference.filter=activelimit&default.retries=0&default.timeout=60000&dubbo=2.8.4&interface=com.bbtree.school.api.interfaces.IClassRpcService&methods=getClass,findPageClasses,removeClass,updateClass,addGraduateRelationShip,getGraduateRelationShip,findClassDetailes,findClassesList,findClassByschoolId,findByUserId,findClasses,addClass,findPageClassesList&pid=12676&revision=0.0.3-SNAPSHOT-client&serialization=kryo&side=consumer×tamp=1513591044602, cause: Fail to decode request due to: RpcInvocation [methodName=findPageClassesList, parameterTypes=[class com.bbtree.school.api.vo.ClassTeacherVo, null, null, null], arguments=null, attachments={path=com.bbtree.school.api.interfaces.IClassRpcService, input=456, dubbo=2.8.4, version=0.0.0}]

有懷疑是環(huán)境問題，但是通過同事電腦啟動該項目，本地連也連不上。不是運維搞得把戲，因為這個項目下有的接口可以調(diào)通，有的不行
傳輸?shù)膮?shù)com.bbtree.school.api.vo.ClassTeacherVo中是否有不能序列化的屬性？
檢查一下 RPC 接口方法的參數(shù)、返回值有沒有特殊類型, 有沒有實現(xiàn)序列化接口.
點對點直連的話需要配置注冊中心的register屬性為false,默認為true,表示使用注冊中心,為false時才使用點對點直連的方式.
