我正在使用Netty Web服务器,它应该使用Hibernate检索数据并将响应返回给客户端。
所以我只是想知道我的实现是否正确
ChannelPipeline pipeline = ch.pipeline();
EventExecutorGroup ex = new DefaultEventExecutorGroup(64);
pipeline.addLast("decoder", new HttpRequestDecoder());
pipeline.addLast("aggregator", new HttpObjectAggregator(65536));
pipeline.addLast("encoder", new HttpResponseEncoder());
pipeline.addLast("chunkedWriter", new ChunkedWriteHandler());
pipeline.addLast(ex,"handler", new HttpWebServerHandler());
然后在messageReceived
方法内部:
@Override
public void messageReceived(ChannelHandlerContext ctx, FullHttpRequest request)
throws Exception {
if (!request.getDecoderResult().isSuccess()) {
sendError(ctx, BAD_REQUEST);
return;
}
ctx.executor().execute(new MyRunnable(ctx));
}
并且在Runnable中:
@Override
public void run() {
SomeObejct so = HibernateTemplate.getSomeObject() ;
String serializedSo = serialize(so);
FullHttpResponse res = new DefaultFullHttpResponse(
HTTP_1_1, OK, Unpooled.copiedBuffer(serializedSo, CharsetUtil.UTF_8));
res.headers().set(CONTENT_TYPE, "text/plain; charset=UTF-8"); ctx.write(res).addListener(ChannelFutureListener.CLOSE);
}
我做得对吗?

是的,这看起来是正确的。您可能想要考虑的是从ChannelPipeline中删除HttpObjectAggregator,从而节省一些内存开销。但请注意,您需要自己处理不同的HTTP消息部分。
