Description
Camel's zipkin spring boot thing uses wildcard mappings to properties like this:
# the zipkin service name
camel.zipkin.server-service-mappings.*=service1
camel.zipkin.client-service-mappings.*=service2
The corresponding @ConfigurationProperties would receive a map entry for the wildcard into a map field like this: private Map<String, String> clientServiceMappings
The last version this worked on was Spring Boot 2.0 M7. Afterwards, this mapping fails with the following exception:
Caused by: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [java.util.Map<java.lang.String, java.lang.String>] at org.springframework.core.convert.support.GenericConversionService.handleConverterNotFound (GenericConversionService.java:321)
So that you don't have to build camel, you can paste the below into a start.spring.io app, setting the above as application.properties
@SpringBootApplication
@EnableConfigurationProperties(ZipkinConfigurationProperties.class)
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}@ConfigurationProperties(prefix = "camel.zipkin")
public class ZipkinConfigurationProperties {
private Map<String, String> clientServiceMappings;
private Map<String, String> serverServiceMappings;
public Map<String, String> getClientServiceMappings() {
return clientServiceMappings;
}
public void setClientServiceMappings(Map<String, String> clientServiceMappings) {
this.clientServiceMappings = clientServiceMappings;
}
public Map<String, String> getServerServiceMappings() {
return serverServiceMappings;
}
public void setServerServiceMappings(Map<String, String> serverServiceMappings) {
this.serverServiceMappings = serverServiceMappings;
}
}
