I have a Spring Boot application that uses a Spring Integration Stored Procedure Inbound Channel Adapter. I would like to pass a command line argument to the stored procedure. The Spring Boot doc says that SpringApplication will convert any command line option arguments starting with ‘--’ to a property and add it to the Spring Environment. What is the correct way to access this property in the int-jdbc:parameter element?
Application.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
@SpringBootApplication
public class Application {
public static void main(String[] args) throws Exception {
ConfigurableApplicationContext ctx = new SpringApplication("integration.xml").run(args);
System.out.println("Hit Enter to terminate");
System.in.read();
ctx.close();
}
}
integration.xml
<int-jdbc:stored-proc-inbound-channel-adapter
stored-procedure-name="sp_get_some_records"
data-source="dataSource"
channel="recs.in.channel"
id="recs.in">
<int:poller fixed-rate="86400" time-unit="SECONDS" />
<int-jdbc:parameter name="myarg" type="java.lang.Integer" value="${arg1}" />
</int-jdbc:stored-proc-inbound-channel-adapter>
Using ${arg1} here doesn't seem to get resolved. What is the proper syntax, or do I need to define an additional property or property placeholder?
Starting the app, e.g. with java -jar app.jar --arg1=5 throws an exception of
Error converting typed String value for bean property 'value'; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert value of type [java.lang.String] to required type [java.lang.Integer]; nested exception is java.lang.NumberFormatException: For input string: "${arg1}"
I thought first it had to do with type conversion and tried with
<int-jdbc:parameter name="myarg" type="java.lang.Integer" value="#{ T(java.lang.Integer).parseInt(arg1) }" />
but that didn't work either.
You don't have any Spring Boot stuff.
I mean auto-configuration, which includes PropertyPlaceholderConfigurer, too.
That must be something like this:
@SpringBootApplication
@ImportResource("integration.xml")
public class Application {
public static void main(String[] args) throws Exception {
ConfigurableApplicationContext ctx = SpringApplication.run(Application.class, args);
System.out.println("Hit Enter to terminate");
System.in.read();
ctx.close();
}
}
I've just checked with our barrier sample: https://github.com/spring-projects/spring-integration-samples/tree/master/basic/barrier
