Dubbo invoke命令

连接

telnet localhost 20880

接口列表

ls

接口下方法列表

ls -l MctCoreMerchantBaseInfoService

调用接口

参数已json格式传递

invoke com.bestpay.merchant.core.facade.merchant.MctCoreMerchantBaseInfoService.queryerchantBaseInfoByLoginNo({"loginNo": "[email protected]"})

报错

No such method queryerchantBaseInfoByLoginNo in service MctCoreMerchantBaseInfoService

错误原因：

查看dubbo invoke调用之后的处理 InvokeTelnetHandler
发现在校验参数的时候，会去判断类型是否一致。当我们传入json的时候，参数类型是jsonObject，所以我们得添加一个属性class，来指定参数类型。

解决方案：

在invoke入参中加上入参类型

com.bestpay.merchant.core.facade.merchant.MctCoreMerchantBaseInfoService.queryerchantBaseInfoByLoginNo({"loginNo": "[email protected]", "class": "com.bestpay.merchant.core.model.req.MctCoreMerchantBaseInfoQueryReqDto"})
