Using header-enricher for priority with spring-integration 2.1.0

[Gary Russell]

Yes; if you use

<header-enricher input-channel="replyChannelInput" output-channel="echoInput">
	<priority value="2"/>
</header-enricher>

You get an Integer. But if you do what the OP did

<header-enricher input-channel="in" output-channel="out">
	<header name="priority" value="7"/>
</header-enricher>

You get a String (you can fix this with an expression).

Given that we have a well-known header <priority/>, that works correctly (aside from the schema issue), that is a better way to solve the issue than using an expression.

By the way, another solution is to explicitly type the header...

	<header name="priority" value="7" type="java.lang.Integer" />

Good catch Gary, but we can actually fix that as well. Look at MessageBuilder.verifyType(..). So I'll fix it and will add a test to MessageBuilderTests
