spring动态bean注册示例分享

1.在一些特殊的场景中需要动态向spring注册bean
2.spring版本2.5.6

public class serviceserviceimpl implements serviceservice, applicationcontextaware {

 @override
 public void setapplicationcontext(org.springframework.context.applicationcontext applicationcontext)
   throws beansexception {
  this.context = applicationcontext;
 }

 public void addbeanservice(service service) throws bvsexception {
  if (!context.containsbean(service.getservicename())) {
   class<?> serviceclass = getserviceclass(service.getclassname());
   beandefinitionbuilder beandefinitionbuilder = beandefinitionbuilder.genericbeandefinition(serviceclass);
   beandefinitionbuilder.addpropertyvalue("servicename", service.getservicename());
   registerbean(service.getservicename(), beandefinitionbuilder.getrawbeandefinition());
  }

 }

 /**
  * @desc 向spring容器注册bean
  * @param beanname
  * @param beandefinition
  */
 private void registerbean(string beanname, beandefinition beandefinition) {
  configurableapplicationcontext configurableapplicationcontext = (configurableapplicationcontext) context;
  beandefinitionregistry beandefinitonregistry = (beandefinitionregistry) configurableapplicationcontext
    .getbeanfactory();
  beandefinitonregistry.registerbeandefinition(beanname, beandefinition);
 }

 /**
  * @desc 根据类名查找class
  * @param classname
  * @return
  * @throws bvsexception
  */
 private class<?> getserviceclass(string classname) throws bvsexception {
  try {
   return thread.currentthread().getcontextclassloader().loadclass(classname);
  } catch (classnotfoundexception e) {
   log.error("not found service class:" + classname, e);
   throw new bvsexception("not found service class:" + classname, e);
  }
 }
}
