示例1: UncaughtAppExceptionFilter
//设置package包名称以及导入依赖的类
package com.twitter.finagle.thrift
import com.twitter.finagle.{Service, SimpleFilter}
import com.twitter.io.Buf
import com.twitter.util.Future
import org.apache.thrift.{TApplicationException, TException}
import org.apache.thrift.protocol.{TMessage, TMessageType, TProtocolFactory}
private[finagle] object UncaughtAppExceptionFilter {
def writeExceptionMessage(
thriftRequest: Buf,
throwable: Throwable,
protocolFactory: TProtocolFactory
): Buf = {
val reqBytes = Buf.ByteArray.Owned.extract(thriftRequest)
// NB! This is technically incorrect for one-way calls,
// but we have no way of knowing it here. We may
// consider simply not supporting one-way calls at all.
val msg = InputBuffer.readMessageBegin(reqBytes, protocolFactory)
val name = msg.name
val buffer = new OutputBuffer(protocolFactory)
buffer().writeMessageBegin(
new TMessage(name, TMessageType.EXCEPTION, msg.seqid))
// Note: The wire contents of the exception message differ from Apache's Thrift in that here,
// e.toString is appended to the error message.
val x = new TApplicationException(
TApplicationException.INTERNAL_ERROR,
s"Internal error processing $name: '$throwable'")
x.write(buffer())
buffer().writeMessageEnd()
Buf.ByteArray.Owned(buffer.toArray)
