消息来自queueChannel尝试发送到特定IP。
适配器是......
@Bean
public AbstractConnectionFactory plainClientFactory() {
int port = Integer.parseInt(outboundPort);

ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
scheduler.setPoolSize(PROCESS_SIZE);
scheduler.setThreadFactory(plainAffinityThreadFactory());
scheduler.setWaitForTasksToCompleteOnShutdown(true);
return scheduler;
}
配置是......
@Resource(name = "sslClientHandler")

}
@Bean
public MessageChannel outputWithSslJsonBytesToClient() {
return MessageChannels.queue(POOL_SIZE).get();
}
InboundServiceImpl是......
@Override
public Object extractPayloadAsJson(byte[] message) throws Exception {
log.debug("receive bytes... {} bytes", message.length);
StringBuffer sb = new StringBuffer();
for (byte b : message) {
sb.append(b);
}

}
@Override
public byte[] attachHeader(byte[] payload) throws Exception {

}
log.debug("concat to string : {}", sb.toString());
return concat;
}
但是,当您尝试传输数据时会发生错误...
为什么会出现这种错误?

答案 0 :(得分:0)
为什么在将Java序列化转换为JSON后将其应用于有效负载? ...
.transform(new PayloadSerializingTransformer())
...解码时你没有反过来。
172是0xac
- 这是java序列化对象的第一个“魔术”头字节。
同样为什么所有的标头操作,如果你将有效负载转换为包含标题的List,JSON(de)序列化也会处理标题。
