如何为Tomcat响应设置writeTimeout？更具体地说，我的意思是NioChannel的writeTimeout中的KeyAttachment - 字段，在将块写入Socket并且默认为无限时使用，这不适合我的用例。我只能找到有关如何设置读取超时或connectionTimeout的信息。
使用KeyAttachment中的writeTimeout的代码可在此处找到：http://grepcode.com/file/repo1.maven.org/maven2/org.apache.tomcat.embed/tomcat-embed-core/8.0.24/org/apache/coyote/http11/InternalNioOutputBuffer.java#129
NioEndpoint.KeyAttachment att = (NioEndpoint.KeyAttachment)socket.getAttachment();
if ( att == null ) throw new IOException("Key must be cancelled");
long writeTimeout = att.getWriteTimeout();
