]]>使用mysql的replace函数替换字符串http://www.blogjava.net/kevinwu/archive/2007/04/13/110470.html吴涛涛吴涛涛Fri, 13 Apr 2007 08:03:00 GMThttp://www.blogjava.net/kevinwu/archive/2007/04/13/110470.htmlhttp://www.blogjava.net/kevinwu/comments/110470.htmlhttp://www.blogjava.net/kevinwu/archive/2007/04/13/110470.html#Feedback6http://www.blogjava.net/kevinwu/comments/commentRss/110470.htmlhttp://www.blogjava.net/kevinwu/services/trackbacks/110470.html
比如你要将 表 tb1里面的 f1字段的abc替换为def

UPDATE tb1 SET f1=REPLACE(f1, 'abc', 'def');

REPLACE(str,from_str,to_str)   
在字符串   str   中所有出现的字符串   from_str   均被   to_str替换，然后返回这个字符串：   
mysql>   SELECT   REPLACE('www.mysql.com',   'w',   'Ww'); 
                  ->   'WwWwWw.mysql.com' 
这个函数是多字节安全的。

示例：
UPDATE  `dede_addonarticle`  SET body =  REPLACE ( body,
 '</td>',
 '' );
UPDATE  `dede_addonarticle`  SET body =  REPLACE ( body,
 '</tr>',
 '' );
UPDATE  `dede_addonarticle`  SET body =  REPLACE ( body,
 '<tr>',
 '' );      
UPDATE  `dede_archives`  SET title=  REPLACE ( title,
 '大洋新闻 - ',
 '' ); 
UPDATE  `dede_addonarticle`  SET body =  REPLACE ( body,
 '../../../../../../',
 'http://special.dayoo.com/meal/' );

mysql replace

用法1.replace intoreplace into table (id,name) values(‘1‘,‘aa‘),(‘2‘,‘bb‘)
此语句的作用是向表table中插入两条记录。
2.replace(object, search,replace)
把object中出现search的全部替换为replaceselect replace(‘www.163.com‘,‘w‘,‘Ww‘)--->WwW wWw.163.com

例：把表table中的name字段中的 aa替换为bbupdate table set name=replace(name,‘aa‘,‘bb‘)

]]>AtLeap中运用Mysqlhttp://www.blogjava.net/kevinwu/archive/2007/03/29/107314.html吴涛涛吴涛涛Thu, 29 Mar 2007 11:46:00 GMThttp://www.blogjava.net/kevinwu/archive/2007/03/29/107314.htmlhttp://www.blogjava.net/kevinwu/comments/107314.htmlhttp://www.blogjava.net/kevinwu/archive/2007/03/29/107314.html#Feedback0http://www.blogjava.net/kevinwu/comments/commentRss/107314.htmlhttp://www.blogjava.net/kevinwu/services/trackbacks/107314.htmlWINDOWS2003、JDK 1.5.0_11、ANT 1.6.5、Tomcat 5.0.27、MySQL4.1.10a；
先设置好环境变量；

2、数据库设置
#database.jar=${mysql.jar}
#database.jar.name=${mysql.jar.name}
#database.dir=${mysql.dir}
#database.version=${mysql.version}
#database.type=mysql
#database.name=${webapp.name}_db
#database.host=localhost
#database.port=3306
#database.driver_class=com.mysql.jdbc.Driver
#database.url=jdbc:${database.type}://${database.host}:${database.port}/${database.name}?characterEncoding=utf-8&amp;useUnicode=true&amp;autoReconnect=true
#database.username=test
#database.password=test
#hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect


改为：
database.jar=${mysql.jar}
database.jar.name=${mysql.jar.name}
database.dir=${mysql.dir}
database.version=${mysql.version}
database.type=mysql
database.name=${webapp.name}_db
database.host=localhost
database.port=3306
database.driver_class=com.mysql.jdbc.Driver
database.url=jdbc:${database.type}://${database.host}:${database.port}/${database.name}?characterEncoding=utf-8&amp;useUnicode=true&amp;autoReconnect=true
database.username=数据库用户名
database.password=数据库密码
hibernate.dialect=org.hibernate.dialect.MySQLDialect

在数据库初始化的过程中，提示${hibernate.transaction.factory_class}，我就在properties.xml中将
<entry key="hibernate.transaction.factory_class" value="${hibernate.transaction.factory_class}"/>

改为
<entry key="hibernate.transaction.factory_class" value="org.hibernate.transaction.JDBCTransactionFactory"/>

就可以通过；

3、服务器设置
1)
# Jetty is embeded into AtLeap distribitive
appserver.type=jetty5
appserver.http.port=8080
# in order to enable support HTTPS please reconfigure jettyplus.xml
appserver.https.port=8443
# the memory sizes
jetty.initialmemory=128m
jetty.maxmemory=256m

改为：
# Jetty is embeded into AtLeap distribitive
# appserver.type=jetty5
# appserver.http.port=8080
# in order to enable support HTTPS please reconfigure jettyplus.xml
# appserver.https.port=8443
# the memory sizes
# # jetty.initialmemory=128m
jetty.maxmemory=256m

2)
# Please specify tomcat5 or tomcat5.5
#appserver.type=tomcat5.5
#appserver.http.port=8080
#appserver.https.port=8443

#tomcat.manager.host=${appserver.host}
#tomcat.manager.port=${appserver.http.port}
#tomcat.manager.url=http://${tomcat.manager.host}:${tomcat.manager.port}/manager
#tomcat.manager.username=manager
#tomcat.manager.password=manager

改为：
# Please specify tomcat5 or tomcat5.5
appserver.type=tomcat
appserver.http.port=8080
appserver.https.port=8443

tomcat.manager.host=${appserver.host}
tomcat.manager.port=${appserver.http.port}
tomcat.manager.url=http://${tomcat.manager.host}:${tomcat.manager.port}/manager
tomcat.manager.username=manager
tomcat.manager.password=manager

4、部署设置
# Usually you do not need to specify below properties
#tomcat.home=C:/TOOLS/java/jakarta-tomcat-5.5.7
#tomcat.app.base=${tomcat.home}/webapps
#tomcat.service.name=Catalina
#tomcat.work.dir=${tomcat.home}/work/${tomcat.service.name}/${appserver.host}/${context.doc.base}
#tomcat.conf.dir=${tomcat.home}/conf/${tomcat.service.name}/${appserver.host}

改为：

# Usually you do not need to specify below properties
tomcat.home=c:/tomcat
tomcat.app.base=${tomcat.home}/webapps
tomcat.service.name=Catalina
tomcat.work.dir=${tomcat.home}/work/${tomcat.service.name}/${appserver.host}/${context.doc.base}
tomcat.conf.dir=${tomcat.home}/conf/${tomcat.service.name}/${appserver.host}

回到build.xml所在的目录，执行ant deploy；

5、测试运行
http://localhost:8080/atleap

参考文档：Blandware AtLeap 安装说明

有朋友说配置Mysql运行比较容易，还没有尝试；

AtLeap支持多语言，听说还获得了不少奖，应该是一个不错的CMS，有空好好看看。
