如何在普通类中调用spring中注册的service类

先写一个factory
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;public class BeanFactoryProxy
{
private ApplicationContext ac;
private XmlBeanFactory xbf;
private BeanFactory factory; public BeanFactoryProxy(BeanFactory factory)
{

}
public BeanFactoryProxy(ApplicationContext ac)
{
this.ac = ac;
} public BeanFactoryProxy(XmlBeanFactory xbf)
{
this.xbf = xbf;
} public Object getBean(String beanId)
{
if (null != ac)
{
return ac.getBean(beanId);
}
else if (null != xbf)
{
return xbf.getBean(beanId);
}
else if (null != factory)
{
return factory.getBean(beanId);
}
else
{
throw new RuntimeException("BeanFactoryProxy has not Inited");
}
}}再写一个框架类包含该factory
public class Framework
{ private static BeanFactoryProxy beanFactoryProxy;
private static int state = -1; public static void initialize(File configFile)
{
//TODO
state = 1;
}

public static int getState(){
return state;
} public static void destroy()
{
//TODO
} /**
* @return
*/
public static BeanFactoryProxy getBeanFactoryProxy()
{
return beanFactoryProxy;
} /**
* @param proxy
*/
public static void setBeanFactoryProxy(BeanFactoryProxy proxy)
{
beanFactoryProxy = proxy;
}}在服务器启动时就装载的类
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;public class FrameworkInitializerServlet extends HttpServlet
{
public static File configFile = null; public void init(ServletConfig config) throws ServletException
{
super.init(config);
Framework.initialize(null);
         WebApplicationContext wac =   WebApplicationContextUtils.getRequiredWebApplicationContext(config.getServletContext());
        Framework.setBeanFactoryProxy(new BeanFactoryProxy(wac));
} /**
* @see javax.servlet.Servlet#destroy()
*/
public void destroy()
{
super.destroy();
Framework.destroy();
}
}初始化rpc类服务器启动时运行
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.apache.xmlrpc.XmlRpc;
import org.apache.xmlrpc.XmlRpcServer;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;public class XmlRpcSvcServlet extends HttpServlet
{
// XML-RPC 服务对象句柄
private XmlRpcServer server = null; /**
* （非 Javadoc）
* @see javax.servlet.Servlet#init(javax.servlet.ServletConfig)
*/
public void init(ServletConfig config) throws ServletException
{
super.init(config); // 初始化 xml-rpc server
server = new XmlRpcServer();
XmlRpc.setDefaultInputEncoding("UTF-8"); // 解析配置文件，注册xml-rpc服务
SAXBuilder sb = new SAXBuilder();
sb.setValidation(false);
try
{
Document doc =
sb.build(
config.getServletContext().getRealPath(
"/WEB-INF/xmlrpc-Config.xml"));
Element root = doc.getRootElement(); // 解析注册服务节点 RegServices/Service
Element svcsNode = root.getChild("RegServices");
List list = svcsNode.getChildren("Service");
for (int i = 0; i < list.size(); i++)
{
Element svcNode = (Element) list.get(i);
String svcName = svcNode.getAttributeValue("name");
String className = svcNode.getAttributeValue("classname");
try
{
server.addHandler(
svcName,
Class.forName(className).newInstance());
continue;
}
catch (InstantiationException e1)
{
e1.printStackTrace();
}
catch (IllegalAccessException e1)
{
e1.printStackTrace();
}
catch (ClassNotFoundException e1)
{
e1.printStackTrace();
}
System.out.println(
"Xml-Rpc Service register fail. [name:"
+ svcName
+ "; classname:"
+ className
+ "]");
}
}
catch (JDOMException e)
{
e.printStackTrace();
}
} /**
* （非 Javadoc）
* @see javax.servlet.http.HttpServlet#doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
*/
public void service(
HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/xml");
byte[] result = server.execute(request.getInputStream());
response.setContentLength(result.length);
OutputStream out = response.getOutputStream();
out.write(result);
out.flush();
}
}配置要注册的类
<?xml version="1.0" ?>
<Config>
<RegServices>
<Service name="LogService" classname="XmlRpcService" />
</RegServices>
</Config>XmlRpcService
public class XmlRpcService
{ // 定义RPC服务的方法 private String xml ="..";
/**
* 数据服务接口名常量
*/
private static final String DATA_SERVICE_NAME = "logService";

         //调用
         public String testRpc()
{
ILogService theService =
(ILogService ) Framework.getBeanFactoryProxy().getBean(
DATA_SERVICE_NAME);
return theService.testRpc();
}
}
spring与struts的结合
