Cal.composite(*.composite文件必需位于classLoader能找到的位置
)

<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" xmlns:c="http://Cal" targetNamespace="http://Cal" name="Cal">
<component name="CalServiceComponent">
<implementation.java class="cal.CalService" />
<reference name="addService" target="AddServiceComponent" />
</component>
<component name="AddServiceComponent">
<implementation.java class="cal.AddService" />
</component>
</composite>

 CalService.java(需要设置addService为reference
)

package cal;

import org.osoa.sca.annotations.Reference;

public class CalService {
private AddService addService;
public int add(int n, int m){
return addService.add(n, m);
}

@Reference//must have this annotation
public void setAddService(AddService addService){
this.addService = addService;
}
}

 AddService.java

package cal;

public class AddService {
public int add(int n, int m){
return n + m;
}
}

 
CalServiceTest.java(可以采用SCADomain方式或SCANode2方式启动，其它方式？
)

package cal;

import static org.junit.Assert.*;

import org.apache.tuscany.sca.host.embedded.SCADomain;
import org.junit.Before;
import org.junit.Test;

import cal.CalService;

public class CalServiceTest {
private SCADomain scaDomain;
private SCANode2 node;
private CalService calService;

@Before
public void init(){
//setupViaSCADomain();
setupViaNode2();
}

@Test
public void testAdd() {
assertEquals(3, calService.add(1, 2));
}

private void setupViaSCADomain(){
scaDomain = SCADomain.newInstance("Cal.composite");
calService = scaDomain.getService(CalService.class, "CalServiceComponent");
}

private void setupViaNode2(){
node = SCANode2Factory.newInstance().createSCANodeFromClassLoader("Cal.composite", null);
node.start();
calService = ((SCAClient)node).getService(CalService.class, "CalServiceComponent");
}
}
