Ⅱ. Describe what happened

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

还有【beforeMethod】方法类型转换异常

Ⅲ. Describe what you expected to happen

主要的异常产生位置为：
DefaultCoreDoGlobalCommitInterceptor、NettyRemotingClientSendSyncInterceptor、RemotingProcessorProcessInterceptor和SWSeataUtils

DefaultCoreDoGlobalCommitInterceptor类中：
public void beforeMethod(EnhancedInstance objInst, Method method, Object[] allArguments, Class<?>[] argumentsTypes,
MethodInterceptResult result) throws Throwable {
RpcMessage rpcMessage = null;
for(Object arg:allArguments) {
if (arg instanceof RpcMessage) {
rpcMessage = (RpcMessage) arg;
if (!(rpcMessage.getBody() instanceof AbstractMessage)) {
return;
}
}
}

/* 异常产生位置
    RpcMessage rpcMessage = (RpcMessage) allArguments[0];
    if (!(rpcMessage.getBody() instanceof AbstractMessage)) {
        return;
    }*/

。。。
@OverRide
public Object afterMethod(EnhancedInstance objInst, Method method, Object[] allArguments, Class<?>[] argumentsTypes,
Object ret) throws Throwable {
for(Object arg:allArguments){
if(arg instanceof RpcMessage){
RpcMessage rpcMessage = (RpcMessage) arg;
if (rpcMessage.getBody() instanceof AbstractMessage) {
ContextManager.stopSpan();
}
}
}

/* 异常产生位置
    RpcMessage rpcMessage = (RpcMessage) allArguments[0];
    if (rpcMessage.getBody() instanceof AbstractMessage) {
        ContextManager.stopSpan();
    }*/
    return ret;
}

NettyRemotingClientSendSyncInterceptor类中：
@OverRide
public Object afterMethod(EnhancedInstance objInst, Method method, Object[] allArguments, Class<?>[] argumentsTypes,
Object ret) throws Throwable {
for(Object arg:allArguments){
if(arg instanceof RpcMessage){
RpcMessage rpcMessage = (RpcMessage) arg;
if (rpcMessage.getBody() instanceof AbstractMessage) {
ContextManager.stopSpan();
}
}
}

/*RpcMessage rpcMessage = (RpcMessage) allArguments[0];
    if (rpcMessage.getBody() instanceof AbstractMessage) {
        ContextManager.stopSpan();
    }*/

    return ret;
}

RemotingProcessorProcessInterceptor类中：
@OverRide
public Object afterMethod(EnhancedInstance objInst, Method method,
Object[] allArguments, Class<?>[] argumentsTypes,
Object ret) throws Throwable {
for(Object arg:allArguments){
if(arg instanceof RpcMessage){
RpcMessage rpcMessage = (RpcMessage) arg;
if (rpcMessage.getBody() instanceof AbstractMessage) {
ContextManager.stopSpan();
}
}
}

/*RpcMessage rpcMessage = (RpcMessage) allArguments[0];
    if (rpcMessage.getBody() instanceof AbstractMessage) {
        ContextManager.stopSpan();
    }*/

    return ret;
}

SWSeataUtils类中：
public static String convertXid(RpcMessage rpcMessage) {
String xid = null;
// 调整后
if(rpcMessage != null && rpcMessage.getBody() != null){
if(rpcMessage.getBody() instanceof AbstractMessage){
AbstractMessage subMessage = (AbstractMessage) rpcMessage.getBody();
String requestSimpleName = rpcMessage.getBody().getClass().getSimpleName();

try {
                xid = SWSeataConstants.TRANSACTION_TRANSMISSION_CLASS_NAME_MAPPING.get(requestSimpleName) != null
                        ? (String) SWSeataConstants.TRANSACTION_TRANSMISSION_CLASS_NAME_MAPPING.get(requestSimpleName)
                        .getDeclaredMethod("getXid").invoke(subMessage)
                        : xid;
            } catch (Throwable e) {
                LOGGER.error("convert seata xid failure", e);
            }
        }
    }

    return xid;
}

以上是测试通过后的代码调整，仅供参考

Ⅵ. Environment:

• JDK version(e.g. java -version ): jdk 8
• Seata client/server version: 2.0.0
• Database version:
• OS(e.g. uname -a ):
• Others: skywalking-java-agent 9.0.0-alpine
