Hello Camel community,
We are currently facing an issue while using Apache Camel split in combination
with ZipAggregationStrategy. The temporary ZIP file created in the
ZipAggregationStrategy is not being deleted after all messages have been split
and processed. This is leading to unnecessary file accumulation as well as
security concerns as the file remains unencrypted in file system. Although we
can see that the “onComplete” method in ZipAggregationStrategy is already
implemented but it seems not to get called at all as we have tried to debug the
code, which is, based on our understanding, not an expected behavior. The
Behavior is the same in Apache Camel 2.x and 3.x.
Here is an example unit test to reproduce the issue:
@Test
public void testAggregationOnCompletion() throws Exception {
getMockEndpoint("mock:result").expectedMessageCount(3);
template.sendBody("direct:start",
"<messages><message>a</message><message>b</message><message>c</message></messages>");
assertMockEndpointsSatisfied();
}
@Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start")
.split(body().tokenizeXML("message", "*"), new
ZipAggregationStrategy()))
.streaming()
.stopOnException()
.to("mock:result");
}
};
}
With the ZipSplitter we have the same results:
@Test
public void testAggregationOnCompletion() throws Exception {
getMockEndpoint("mock:result").expectedMessageCount(1);
template.sendBody("direct:start", "message AAAA");
assertMockEndpointsSatisfied();
}
@Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start")
.marshal().zipFile()
.split(new ZipSplitter(), new ZipAggregationStrategy())
.streaming()
.stopOnException()
.log("Split message: ${body}")
.process(exchange -> {
String originalFileName =
exchange.getIn().getHeader("CamelFileName", String.class);
exchange.getIn().setHeader("CamelFileName",
"proccessed_" + originalFileName);
})
.end()
.to("mock:result");
}
};
}
Any insights or suggestions would be greatly appreciated.
Thank you in advance for your help!
