springmvc整合memcached，无法初始化SockIO pool，困惑！30

自己做了一个springMVC+memcached的示例，启动的时候抛了这个错误 [ERROR] attempting to get SockIO from uninitialized pool!

memcachedPool可能有点问题，请大家帮忙看下，谢谢了。

备注：查了很多资料，咱们iteye中有人遇到过相同的问题，我按照他解决的办法并没有起作用。

pengmj 给出的解决办法是在 <bean id="memcahedPool"中加入lazy-init= false，也不行。大家帮看下我的代码哪里有问题~先谢过哈

spring配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

</beans>

使用了基于注解的方式，Controller类如下

package com.test.web;
import java.util.Date;
import javax.servlet.http.HttpSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import com.danga.MemCached.MemCachedClient;
import com.test.utils.MemcachedUtils;

@Controller
@RequestMapping("/loginController")
public class Login {
	
	@Autowired
	private MemCachedClient mcc;
	
	@RequestMapping("/login")
	public ModelAndView login(
			@RequestParam(value = "username") String userid,
			@RequestParam(value = "password") String passwd, HttpSession session){
		
		ModelAndView m = new ModelAndView();
		m.setViewName("../index");
		
		MemcachedUtils.set("test", "hello memcached",new Date(1000 * 60));//这里有问题！
		Object o = MemcachedUtils.get("test");//这里有问题！
		System.out.println(o.toString());
		m.addObject("errMsg","成功返回！");			
		return m;	
	}
	
}

MemcachedUtils类代码如下：

import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.apache.log4j.Logger;
import com.danga.MemCached.MemCachedClient;

public class MemcachedUtils {
	private static final Logger logger = Logger.getLogger(MemcachedUtils.class);  
    private static MemCachedClient cachedClient;  
    static {  
        if (cachedClient == null)  
            cachedClient = new MemCachedClient();  
    }  
  
    private MemcachedUtils() {  
    }  
    /** 
     * 添加memcached。 
     */   
    public static boolean set(String key, Object value, Date expire) {  
        return setExp(key, value, expire);  
    }  
	
    private static boolean setExp(String key, Object value, Date expire) {  
        boolean flag = false;  
        try {  
            flag = cachedClient.set(key, value, expire);  
        } catch (Exception e) {  
			logger.error(""Memcached set方法报错，key值：" + key + "\r\n"", e); 			
        }  
        return flag;  
    }
    /** 
     * 获取memcached。 
     */     
    public static Object get(String key) {  
        Object obj = null;  
        try {  
            obj = cachedClient.get(key);  
        } catch (Exception e) {  
			logger.error(""Memcached get方法报错，key值：" + key + "\r\n"", e); 
        }  
        return obj;  
    }   
 
}

执行login类的login方法时出现[ERROR] attempting to get SockIO from uninitialized pool!大家帮看看，先谢过了哈。

错误堆栈信息如下：
