曾经用Android开发过学校教务系统的登录功能(jsp/tomcat)，能够成功模拟出Http请求. 但是WordPress的登录功能实现起来要绕一个弯子. 不能直接用HttpClient来得到cookie.
这位兄弟遇到的问题跟我是一样的 http://hi.baidu.com/xtitman/item/eeaef4c7d4a0e2bc0c0a7b69最后也是成功用socket方法把功能实现了. 其中为如何用socket模拟http的post/get请求消息头以及消息体纠结了几个小时。
My codes are as follows. Please ignore the animation part and focus on the method run() in class MyThread. It's just a demo and I didn't make any post-procession with the result. And if you have any question about this demo, please send an e-mail to davyjones2010@gmail.com which I would appreciate much.

// 首先采用socket方式模拟浏览器发出第一个Post请求访问第一个网页(携带的参数是username和 password, 消息头以及消息体必须遵守post/get的严格格式)
// 之后得到第一个网页的HttpResponse, 从中提取出由服务器加密之后的username和password
// 第一个网页由于返回状态码302因而需要进行重定向到真正的DashBoard即登录成功页面
// 重定向是需要重新发送一个请求, 通过FireBug可以得知需要得到的是GET请求
// 并且携带的cookie是包含上次请求返回的加密之后username和password
// 所以这次模拟的重定向可以直接使用HttpGet, 然后调用httpGet.addHeader("Cookie", 加密之后的用户名 + 加密之后的密码 + 其他信息(是静态的信息, 可以由FireBug探测得知));
// 從而得到真正的DashBoard页面
// 为什么第一次请求需要用底层的socket呢？而不直接使用HttpPost/HttpClient呢？可以通过使用相应方法(getHeaders()?getCookie()?)得到cookies, 而不需要自己来拼串
// 原因是发现第一次的请求返回的cookies, 是 httpOnly的, 采用HttpClient方式遍历headers可以发现是打印不出来的！也就是说不能用上层的这些方法了
// 所以之后采用socket方法模拟POST请求了, 得到的是未经过加工处理的response, 采用String的相应方法拼串可以提取出cookies

<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop><!-- 缓存插件 -->
<prop key="hibernate.cache.use_query_cache">true</prop><!-- 是否开启查询缓存 -->
然后在src目录下添加ehcache.xml文件，文件内容：
<ehcache>
<diskStore path="C:\\cache"/>
<defaultCache
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="true"
/>
<cache name="NEVER_OVERDUE"
maxElementsInMemory="1000"
eternal="true"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
overflowToDisk="false"
/>
</ehcache>
最后在需要缓存的映射文件中配置：
<cache usage="read-write"/> 一般配置在class标签里面的第一个

一.表空间的创建
1.创建普通表空间指定初始大小，自动扩展，最大大小：
(oracle允许的单个smallfile数据文件最大大小为 4194302*blocksize,单个bigfile数据文件最大可达到(32-128)TB)
(默认创建表空间为标准的8k数据块，smallfile表空间)
create tablespace t1 datafile '/u01/oracle/product/oradata/orcl/t1.dbf' size 10m autoextend on next 5m maxsize 100m;
2.创建非标准块大小的表空间:
alter system set db_16k_cache_size=100m scope=spfile;
shutdown immediate;
startup;
create tablespace t2 datafile '/u01/oracle/product/oradata/orcl/t2.dbf' size 10m blocksize 16k;
3.创建大文件表空间(大文件表空间只允许有一个数据文件)：
create bigfile tablespace t3 datafile '/u01/oracle/product/oradata/orcl/t3.dbf' size 10m ;
二.修改表空间（如果修改临时表空间，注意将语句中的datafile改为tempfile）:
1.在表空间中添加数据文件：
alter tablespace t1 add datafile '/u01/oracle/product/oradata/orcl/t11.dbf' size 1m;
2.在表空间中删除数据文件:
alter tablespace t1 drop datafile '/u01/oracle/product/oradata/orcl/t11.dbf';
3.修改指定数据文件的大小
alter database datafile '/u01/oracle/product/oradata/orcl/t1.dbf' resize 1m;
三。表空间与数据文件的offline与online
1.表空间的脱机与联机
alter tablespace t1 offline;
alter tablespace t1 online;
2.数据文件的脱机与联机(数据文件的脱机与联机需要使用归档模式,数据文件脱机后一定要执行数据文件介质恢复，否则会报错)
shutdown immediate;
startup mount;
alter database archivelog;
alter database open;
alter database datafile '/u01/oracle/product/oradata/orcl/t1.dbf' offline;
recover datafile 5;
alter database datafile '/u01/oracle/product/oradata/orcl/t1.dbf' online;
四。表空间改名
alter tablespace t1 rename to t4;
五.表空间删除
1。正常删除表空间，不删除数据文件：
drop tablespace t4 ;
2.删除表空间同时删除所有相关数据文件;
drop tablespace t2 including contents and datafiles;
六。使用已经存在但未使用的数据文件创建表空间:
SQL> create tablespace t1 datafile '/u01/oracle/product/oradata/orcl/t1.dbf' size 10m;
create tablespace t1 datafile '/u01/oracle/product/oradata/orcl/t1.dbf' size 10m
*
ERROR at line 1:
ORA-01119: error in creating database file
'/u01/oracle/product/oradata/orcl/t1.dbf'
ORA-27038: created file already exists
Additional information: 1
SQL> create tablespace t1 datafile '/u01/oracle/product/oradata/orcl/t1.dbf' reuse;
Tablespace created.
