dubbo泛化调用异常 #10165

Closed freegaga closed 2 years ago

freegaga commented 2 years ago

Environment

Steps to reproduce this issue

ReferenceConfig reference = new ReferenceConfig(); reference.setInterface("com...**"); reference.setGroup(group); reference.setVersion(version); reference.setRetries(retryTime);

    RpcContext.getContext().setAttachment("generic", "gson");
    reference.setGeneric(true);
    reference.setCheck(false);
    reference.setTimeout(100000);

    GenericService genericService = ReferenceConfigCache.getCache().get(reference);
    Map<String, Object> result = (Map<String, Object>) genericService.$invoke(method, new String[]{param.getClass().getName()}, new Object[]{JSONObject.toJSONString(param)});

上面是泛化调用代码

1，系统启动第一次通过泛化调用dubbo服务会报如下错误，但是第二次调dubbo服务就正常了。 2，我尝试过在调用dubbo服务的地方发生异常时捕获异常在重试也不行

Pls. provide [GitHub address] to reproduce this issue.

Expected Behavior

If there is an exception, please attach the exception trace:

com.cloud.hub.dto.Command 这个参数是入参还是出参

freegaga commented 2 years ago

@AlbumenJ @mercyblitz com.cloud.hub.dto.Command 这个参数是入参还是出参

这个是入参，伪代码如下 @Override public Res command(Command command) { JSONObject param = new JSONObject(); @param.put("key","test"); return Res.data(param); }

twz007 commented 2 years ago

reference.setGeneric("gson"); 还有问题的话，可以在provider侧断点调试：org.apache.dubbo.rpc.filter.GenericFilter#invoke @freegaga

freegaga commented 2 years ago

@AlbumenJ @mercyblitz image

感觉是这里的问题 image

AlbumenJ commented 2 years ago

这里面是请求的业务实现的，你可以查一下你的服务端实现是不是有问题

AlbumenJ commented 2 years ago

wrapper.invokeMethod 是调用 proxy（服务端实现对象）的指定方法

freegaga commented 2 years ago

这里面是请求的业务实现的，你可以查一下你的服务端实现是不是有问题

@AlbumenJ 我查了下服务端没有什么问题， 现在我是通过如下方法解决的。但是这种方法不是很好。

AtomicBoolean flag = flagMap.get(group); if(null == flag || !flag.get()){//第一次调用 result = (Map<String, Object>) genericService.$invoke(method, new String[]{param.getClass().getName()}, new Object[]{PojoUtils.generalize(param)}); flag = new AtomicBoolean(true); flagMap.put(group,flag); }else{//非第一次调用 result = (Map<String, Object>) genericService.$invoke(method, new String[]{param.getClass().getName()}, new Object[]{JSONObject.toJSONString(param)}); }

你在服务端打断点，第一次请求到 wrapper.invokeMethod 的时候看下是不是抛异常了，如果是的话再去业务代码里面打断点

chickenlj commented 2 years ago

因为你传的参数值是 Json 格式的

Map<String, Object> result = (Map<String, Object>) genericService.$invoke(method, new String[]{param.getClass().getName()}, new Object[]{JSONObject.toJSONString(param)});

这个方法也尝试下 reference.setGeneric("gson"); 或者 reference.setGeneric("json");
