Hello everyone:
I'm new to hivemind. I'm from China.
I want to use ServiceImplementationFactory to produce Service, here is the code:
------------------------------------------------------------------------------------------------------------------------------------
Interface: Hello.java
package cn.topsmart.test;
public interface Hello {
public void sayHello();
}
---------------------------------------------------------------------------------------------------------------------------------------
HelloFactory.java
package cn.topsmart.test;
import org.apache.hivemind.ServiceImplementationFactory;
import org.apache.hivemind.ServiceImplementationFactoryParameters;
public class HelloFactory implements ServiceImplementationFactory {
public Object createCoreServiceImplementation(
ServiceImplementationFactoryParameters factoryParameters) {
return new Hello(){
public void sayHello() {
System.out.println("hello..............");
}
};
}
}
-------------------------------------------------------------------------------------------------------------------------------------------------
hivemodule.xml
<?xml version="1.0"?>
<module id="topsmart" version="0.0.1">
<service-point id="HelloFactory" interface="org.apache.hivemind.ServiceImplementationFactory"/>
<service-point id="Hello" interface="cn.topsmart.test.Hello"/>
<implementation service-id="HelloFactory">
<invoke-factory>
<construct class="cn.topsmart.test.HelloFactory"/>
</invoke-factory>
</implementation>
<implementation service-id="Hello">
<invoke-factory service-id="HelloFactory"/>
</implementation>
</module>
-------------------------------------------------------------------------------------------------------------------------------------
Test.java
Hello hello = (Hello)registry.getService(Hello.class);
hello.sayHello();
-----------------------------------------------------------------------------------------------------------------------------------
But when I run the test code, the mistake appears:
[EMAIL PROTECTED]:16:58 ERROR
(topsmart.Hello) - Error at
file:/E:/projects/topsmart/build/classes/META-INF/hivemodule.xml, line
14, column 46: Parameters to service implementation factory
HelloFactory contains no contributions but expects exactly one
contribution.
I
did not know why this is? Was
any place makes a mistake?
Thanks!
