Hibernate2 配置文件加密
最近公司做配置文件加密项目,遇到一个应用使用的是Hibernate2,在网上没有找到现有的Hibernate2的方案,于是自己参考jasypt的源码,写了一个Connection Provider实现了加密运作
其中Encoded.decrypt加密、解密的类在此不提供,各位自己发挥
import java.util.Properties;
import com.walmart.init.Encoded;
import net.sf.hibernate.HibernateException; import net.sf.hibernate.connection.DriverManagerConnectionProvider;
public final class EncryptedPasswordDriverManagerConnectionProvider extends DriverManagerConnectionProvider {
public void configure(Properties props) { String user = props.getProperty("hibernate.connection.username"); String password = props.getProperty("hibernate.connection.password"); if (isEncryptedValue(user)) { user = getInnerEncryptedValue(user); props.setProperty("hibernate.connection.username", Encoded.decrypt(user)); } if (isEncryptedValue(password)) { password = getInnerEncryptedValue(password); props.setProperty("hibernate.connection.password", Encoded.decrypt(password)); } try { super.configure(props); } catch (HibernateException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public static boolean isEncryptedValue(String value) { if (value == null) { return false; } String trimmedValue = value.trim(); return (trimmedValue.startsWith("ENC(")) && (trimmedValue.endsWith(")")); } private static String getInnerEncryptedValue(String value) { return value.substring("ENC(".length(), value.length() - ")".length()); }
}
Hibernate.cfg.xml文件供参考
<session-factory> <property name="hibernate.connection.provider_class"> com.walmart.china.ConnectionProvider.EncryptedPasswordDriverManagerConnectionProvider </property> <!-- provider --> <!--property name="connection.datasource">java:comp/env/jdbc/mysql</property --> <!-- Test Config Intr@net--> <property name="dialect">net.sf.hibernate.dialect.SQLServerDialect</property> <property name="connection.driver_class">com.ddtek.jdbc.sqlserver.SQLServerDriver</property> <property name="connection.url">jdbc:datadirect:sqlserver://PCNNT57006SQL\NI1:1433;databaseName=pipeline</property> <!-- <property name="connection.driver_class">sun.jdbc.odbc.JdbcOdbcDriver</property> <property name="connection.url">jdbc:odbc:LocalServer;databaseName=pipeline</property> --> <property name="connection.username">user</property> <property name="connection.password">ENC(STMw69FIE6LihJ+vW/myEA==)</property> ...... </session-factory>

  目录贴: 跟我学Shiro目录贴   在涉及到密码存储问题上,应该加密/生成密码摘要存储,而不是存储明文密码。比如之前的600w csdn账号泄露对用户可能造成很大损失,因此应加密/生成不可逆的摘要方式存储。   5.1 编码/解码  Shiro提供了base64和16进制字符串编码/解码的API支持,方便一些编码解码操作。Shiro内部的一些数据的存储/表示都使用了base64和 ...

编辑模式与开发模式微信公众帐号申请成功后,要想接收处理用户的请求,就必须要在“高级功能”里进行配置,点击“高级功能”,将看到如下界面:从上图中可以看到,高级功能包含两种模式:编辑模式和开发模式,并且这两种模式是互斥关系,即两种模式不能同时开启。那两种模式有什么区别呢?作为开发人员到底要开启哪一种呢?编辑模式:主要针对非编程人员及信息发布类公众帐号使用。开启该模式后,可以方便地通

linux 下安装SAP for Java后,发现ABAP功能实在太弱,所以想在Eclipse中开发,结果安装完成之后发现无法连接到SAP,经过漫长的查找发现这个消息,经测试完善解决,总结共享之
ABAP Development Tools (ADT) on Eclipse还没装好?好吧,狂点到这里找方法吧!
找到并打开SAPGUI的settings文件(Mac可参考原文中的路径,下面为Linux)
在末尾增加下面信息,路径修改为与settings文件相同的路径
@INCLUDE = "file:///root/.SAPGUI/connections" @MESSAGESERVER = "file:///root/.SAPGUI/messageserver.txt"
在settings文件的路径下,新建messageserver.txt文件并插入SAP的连接信息
conn=/H/192.168.70.6/S/3200&clnt=200&lang=ZH&expert=true
再次进入ABAP Development Tools (ADT) on Eclipse,新建ABAP项目,选择相应的连接...
Enjoy it : )

调用Smartforms时输出OTF数据:w_cparam-getotf = 'X'.
调用函数CONVERT_OTF将OTF数据转换成PDF二进制文件
将二进制文件使用GUI_DOWNLOAD下载到本地

SAP 池表和簇表的字段列表中不支持聚合函数和附加项 DISTINCT
select sum( DMBTR ) from BSEG into IT_EKPO-YFJE where UMSKZ eq 'A' and EBELN eq EBELN and EBELP eq IT_EKPO-EBELP.
执行以上代码,报错: 池表和簇表的字段列表中不支持聚合函数和附加项 DISTINCT。 DISTINCT are not supported in field lists for pooled and cluster tables.
解决: REF:https://scn.sap.com/message/3572180#3572180
As long as possible we should not use BSEG table for selecting data instead we can use the following tables as the BKPF and BSEG stores the data of the following 6 tables BSID, BSAD --for Account Receivables(customer related ref to Billing Doc) BSIK, BSAK -- for Account Payables (vendor related ref to PO) BSIS and BSAS ---GL related Only in the rare condition when the data is not avialble in the above tables and is there only in BSEG then first write a select to BKPF table into ITAB and for all entries of that ITAB write a select to BSEG and loop and calculate the SUM.

SAP CALL WEB SERVICES - 补充篇3
在实际的工作中,提供WEB SERVICES的平台也会有测试机和正式机,那么在这个时候应该如何在ABAP中快速实现呢?
这个时候,你可能需要了解一下LP(逻辑端口)的作用了,下面贴出关键实现代码(在创建Web Services对象的时候指定逻辑端口)
data: LP type SRT_LP_NAME. case SY-MANDT. when 100."生产机 LP = 'OAPRD'. when others."其他 LP = 'OADEV'. endcase. create object WS exporting LOGICAL_PORT_NAME = LP.
而在此之前,同���需要为新的连接地址设置RFC目标(Tcode:SM59)和新建逻辑端口(Tcode:SOAManager,参见下图)
