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

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;
}
/**

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：
[ERROR] attempting to get SockIO from uninitialized pool!
