话不多说 实例呈上
1 服务端bundle
接口
package ds.example.service;
public interface NameService {
public boolean checkName(String name);
}
实现
package example.osgi;
import org.osgi.service.component.ComponentContext;
import ds.example.service.NameService;
public class NameImpl implements NameService {
String[] m_name = { "Marry", "John", "David", "Rachel", "Ross" };
public void activate(ComponentContext context){
System.out.println("NameService Component Active,within the bundlelifecircle");
}
public void deactivate(ComponentContext context){
System.out.println("NameService Component Deactive,within the bundlelifecircle");
}
@Override
public boolean checkName(String name) {
for (int i = 0; i < m_name.length; i++) {
if (m_name[i].equals(name)) {
return true;
}
}
return false;
}
}
根目录下增加OSGI-INF/component.xml 内容如下
<?xml version="1.0" encoding="UTF-8"?>
<component name="dsExample">
<implementation class="example.osgi.NameImpl"/>
<service>
<provide interface="ds.example.service.NameService"/>
</service>

import ds.example.service.NameService;
public class CheckNameClient {
private NameService nameservice = null;
public void setNameservice(NameService nameservice) {

System.out.println("yyyyyyyy");
}
System.out.println("$$$$$$$$$$$$$$$$$$$$$");
}
public void unsetNameservice(NameService nameservice) {
if (this.nameservice != nameservice)
return;
this.nameservice = null;
}
// protected void activate(ComponentContext context) {
// System.out.println("ddddddddddd");
// NameService namecheck = (NameService) context

// String name="dddd";
// if(namecheck.checkName(name)){
