Nevermind, I have the solution.
My issue was a missing spring bean of type
'PropertySourcesPlaceholderConfigurer' that would then be able to use the
property sources defined with the @TestPropertySource annotation.
The code change:
Add ' PropertySourcesPlaceholderConfigurer.class' to
@ContextConfiguration(classes = {...}):
- @ContextConfiguration(classes =
{ReproduceUnableToLoadProperties.ExampleRouteBuilder.class,
ReproduceUnableToLoadProperties.ContextConfig.class}, loader =
CamelSpringDelegatingTestContextLoader.class)
+ @ContextConfiguration(classes = {PropertySourcesPlaceholderConfigurer.class,
ReproduceUnableToLoadProperties.ExampleRouteBuilder.class,
ReproduceUnableToLoadProperties.ContextConfig.class}, loader =
CamelSpringDelegatingTestContextLoader.class)
Cheers

camel-spring-javaconfig test issue
Kia ora,
I'm having an issue writing a camel-spring-javaconfig test of a camel route
where the RouteBuilder bean relies on Spring to inject fields annotated with
@Value.
This repo: https://github.com/bedebignell/camel-bug-repro/ is able to reproduce
the error by running 'mvn test
-Dtest=nz.bignell.bede.camel.ReproduceUnableToLoadProperties'
The project uses the BOM versions Camel 3.6.0 and Spring 5.1.15.RELEASE and the
dependencies (pom here:
https://github.com/bedebignell/camel-bug-repro/blob/main/pom.xml):
* camel-core
* camel-spring-javaconfig
* camel-spring
* spring-web
// Testing deps
* camel-test
* camel-test-spring
* spring-test
The class extending RouteBuilder relies on Spring to inject to field with a
value (@Value("${rankOfCamel}") int rankOfCamel). When the Spring
@TestPropertySource hasn't been loaded/processed so the int property is
attempted to be loaded with the literal string "${rankOfCamel}" which errors
throwing a NumberFormatException.
Here is the test class (class here:
https://github.com/bedebignell/camel-bug-repro/blob/main/src/test/java/nz/bignell/bede/camel/ReproduceUnableToLoadProperties.java):
package nz.bignell.bede.camel;
import org.apache.camel.ExchangePattern; import
org.apache.camel.ProducerTemplate;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.spring.javaconfig.SingleRouteCamelConfiguration;
import org.apache.camel.test.spring.CamelSpringDelegatingTestContextLoader;
import org.apache.camel.test.spring.CamelSpringRunner;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestPropertySource;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
@RunWith(CamelSpringRunner.class)
@ContextConfiguration(classes =
{ReproduceUnableToLoadProperties.ExampleRouteBuilder.class,
ReproduceUnableToLoadProperties.ContextConfig.class}, loader =
CamelSpringDelegatingTestContextLoader.class)
@TestPropertySource(
properties = {
"rankOfCamel=1"
}
)
public class ReproduceUnableToLoadProperties extends
AbstractJUnit4SpringContextTests {
@Autowired
ProducerTemplate genericProducer;
@Test
public void checkProducer() {
Assert.assertTrue(true);
Assert.assertNotNull(genericProducer);
Object resp = genericProducer.sendBody("direct:testA",
ExchangePattern.InOut, "Klaus");
Assert.assertEquals("hi Klaus", resp);
}
@Component
public static class ExampleRouteBuilder extends RouteBuilder {
@Value("${rankOfCamel}")
int rankOfCamel;
@Override
public void configure() throws Exception {
from("direct:testA")
.log("Camel is number: " + rankOfCamel)
.setBody(constant("hi ").append(body().convertToString()))
;
}
}
@Configuration
public static class ContextConfig extends SingleRouteCamelConfiguration {
ReproduceUnableToLoadProperties.ExampleRouteBuilder exampleRouteBuilder;
// Constructor Injection of Spring bean 'ExampleRouteBuilder'
ContextConfig(ReproduceUnableToLoadProperties.ExampleRouteBuilder
exampleRouteBuilder) {
this.exampleRouteBuilder = exampleRouteBuilder;
}
@Override
@Bean
public RouteBuilder route() {
return exampleRouteBuilder;
}
}
}

Bede
