1. 异常
dubbo无论使用哪个协议传递参数的时候都需要参数实现序列化接口。 所以提示这个很大原因在于传递的参数没有实现序列化但是一般都提示参数为什么提示service 没有实现序列化。 以下是我使用test方法时的异常信息。

2. 分析
极大的可能在于service用了rpc中的request对象构建了匿名内部类。 所以提示 Java field: final xxx.this$0 JDK8 以后,匿名内部类默认用 final 修饰。 这个 UpdateObuStatusRequest 是本来rpc-api的jar中的需要传参数的对象错误代码如下但是在调用的时候使用了匿名内部类。 Autowiredprivate RpcEtcCarInfoService rpcEtcCarInfoService;Testpublic void test() throws InterruptedException {// 2.通知teacherUpdateObuStatusRequest updateObuStatusRequest new UpdateObuStatusRequest() {{this.setCarNum(111);this.setObuActiveNo(1111);}};ExterResponse exterResponse rpcEtcCarInfoService.updateObuStatus(updateObuStatusRequest);System.out.println(JSON.toJSONString(exterResponse));}
跟了下源码可以看到的是。在使用netty进行 消息发送的时候对参数进行序列化用反射获取的是匿名内部类的对应的当前类的对象。刚调用 send 方法的时候看到的request 对象的参数是对的。 进行序列化的时候。发现这个object是当前测试类的对象。 好吧下次注意。另外不建议匿名内部类的写法。
由于创建的对象用final 修饰后直接进入了常量池生存时间不再和调用方法是一样的容易造成 leak memory内存泄露。
