Java 冬眠&；Tomcat-won'；t闭合插座

当我继续向我的Web服务器发送http请求时，它停止响应，我被困在一个白色屏幕上，说“等待xxx”。它没有反应

而且我在stacktrace上没有看到任何异常。我在catalina.out没有看到任何例外

我认为这与tomcat没有关闭套接字连接有关。 这只发生在

$ cd /proc/{processID}/fd
$ ls -l | wc -l

返回超过1000的值。 几乎每次我点击刷新时，“ls-l | wc-l”的返回值都会上升

如果我发出这个命令

$ ll

我看到很多像这样的唱片

lrwx------ 1 root root 64  5월 22 17:49 999 -> socket:[1018379]

我很确定这与我的web应用程序不返回（或不关闭）到数据库的连接无关

我正在使用MySQL，并且已经配置了my.cfg

[mysqld]
wait-timeout=3
interactive-timeout=60

我可以在mysql中查看它

mysql> select @@session.wait_timeout, @@global.wait_timeout;
+------------------------+-----------------------+
| @@session.wait_timeout | @@global.wait_timeout |
+------------------------+-----------------------+
|                     30 |                     3 |
+------------------------+-----------------------+
1 row in set (0.00 sec)

如果我发布

这不是DNS问题。我可以在我的网络服务器上打开网站

netstat -tulpn
tcp        0      0 ::ffff:127.0.0.1:8005       :::*                        LISTEN      21395/java

也

展示很多

我在哪里可以看到Tomcat与MySQL的连接

java    21395 root  390u  IPv6            1380717      0t0       TCP cooingbee.co.kr:40026->cooingbee.co.kr:mysql (CLOSE_WAIT)

我也设置了ulimit

]# ulimit -n 
4096
]#ulimit -Hn
65536

在我的sysctl.conf中，我添加了这些，但仍然没有运气

kernel.shmmni = 4096
kernel.sem = 256 32000 100 128
fs.aio-max-nr = 1048576
fs.file-max = 6815744
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

有关我的服务器环境的其他信息

CentOS 5.x
Java 7
Tomcat6 / 7 (I've tested my webapp on both tomcat 6 and 7)
MySQL 5.5
web application uses Hibernate, c3p0, Spring DI, MVC

我已经从DBMS方面确认，通过使用

show processlist

问题:

什么是“袜子无法识别协议”

如果我有上千条记录，为什么我的雄猫没有反应 /proc/{processID}/fd

我应该怎么做才能使它顺利工作

编辑1 我给你看代码。仅供参考，我既没有设计也无意以这种方式使用Hibernate和Spring。我想你会明白我为什么现在这么说；）

my hibernate.cfg.xml的一部分

就我在internet上搜索的情况而言，不推荐使用getHibernateTemplate（）和HibernateDAOSupport。另外，如果我使用getHibernateTemplate（），我不必手动显式关闭会话，但我感到绝望，所以我添加了“HibernateUtil.tryCLOSELL（）”
