publishSubscribeChannel unit test can't work well - spring-integration

Question

my integration config class is below，when i do some unit test on them,found that:
when i send message to UserRecipientSubscribeCacheChannel,it work well;
when i send a message to an upper level of channel userReportWriteCompletedRouteChannel, it work failed,and it don't throws any exceptions yet. i can't understand it. the messages that i sent is same,of course.
because of the fail section, the next handler can't work ok.
ty!!
it work ok below, it print ===>ip location channel message:GenericMessage [payload=[MailRecipientActionDocumen...and ===>user recipient channel message:GenericMessage [payload=[UserRecipientSubscribeDataRedisStructure...
#Test
public void test_sendMessageUserRecipientSubscribeCacheChannel(){
UserRecipientSubscribeCacheChannel.send(createMessageWithIp());
}
it work fail below, it print ===>ip location channel message:GenericMessage [payload=[MailRecipientActionDocumen... only
notice that: the fail section, In front of handler has a transformer.
#Test
public void test_sendMessageToRouteChannel() {
userReportWriteCompletedRouteChannel.send(createMessageWithIp());
}
my code config below:

.handle(message -> {
System.out.println("===>user recipient channel message:" + message);
})
}
i expect 2 print message info ,but print 1 only.

Today, i found that the bridge flow may had some problem, When I move the handler behind the channeluserReportWriteCompletedSubscribeChannel, it can't print any message;
when i remove channel and add handler directly, it will print message.
does i use the bridge wrong?
#Bean
public IntegrationFlow bridgeFlow() {
return flow -> flow.channel("userReportWriteCompletedRouteChannel")
.bridge(bridgeSpe -> bridgeSpe
.poller(pollerFactory -> pollerFactory.fixedRate(100).maxMessagesPerPoll(1)))
.handle(message -> {
System.out.println("===>route channel message:" + message);
}) // handle ok , will print message
.channel("userReportWriteCompletedSubscribeChannel")
// .handle(message -> {
// System.out.println("===>route channel message:" + message);
// }) // handle fail , will not printing message
;
}
test:
#Test
//invalid
public void test_sendMessageToRouteChannel() {
userReportWriteCompletedRouteChannel.send(createMessageWithIp());
}
