一 : Steam大数据公布出PC玩家应有的基本配置
【61阅读IT新闻频道】Steam每月都会统计游戏玩家的硬件、软件报告，最近，6月份的最新统计也出炉了，一起来看看。
首先来了解下作为一个游戏玩家，大数据眼中基本的PC配置该是怎样。
PC玩家基本配置
可以看到，Win7 64bit操作系统、8GB内存、双核CPU、英特尔HD4000显卡、1080P显示器、250GB以上的硬盘是都是个分类项中的最高，由此也描述了一个普通玩家应有的配置。
PC玩家基本配置
回归到显卡子类，N系独占52%，其中保有量最高就是GTX 970，而且份额一直在增长(0.5GB显存碎碎念……);A家则是HD7900系列打头阵，这里可能涵盖了HD 7970/7950及R9 280X/280这些同核心的显卡。
PC玩家基本配置
在CPU中，Intel仍然是攫取了75%的市占，留给AMD的仅有25%。双核、2.3GHz这样的U仍占主流，当然到了A家，自然起步频率就得3.3GHz走起了。
对比一下这些大数据，各位玩家朋友们有没有拖平均数的后腿呢？

WIN7 64位旗舰版安装OFFICE2003 提示：“错误1919,配置ODBC数据源MS Access Database时发生错误ODEC错误”
在64位系统上，32位软件的注册表的信息不是直接在在Software下，而是在Software\Wow6432Node下才是32位软件的注册信息。
只有64位软件才是直接在Software下的。
找一台win7 32位操作系统的机器导出注册表，位置如下：
HKEY_CURRENT_USER\Software\ODBCHKEY_LOCAL_MACHINE\Software\ODBC
32位的注册导出文件，可以直接用记事本编辑文件，在Software后添加Wow6432Node。也就是：HKEY_CURRENT_USER\Software\Wow6432Node\ODBCHKEY_LOCAL_MACHINE\Software\Wow6432Node\ODBC最后点击导入就可以了.

三 : JNDI数据源配置注意事项
如果是在原有工程上修改
1，applicationContext.xml中修改其中的value值
<bean id="dataSource">
<property name="jndiName">
<value>java:comp/env/jndivalue</value>
</property>
</bean>
2，web.xml中修改res-ref-name
<resource-ref>
<res-ref-name>jndivalue</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
3,tomcat中，conf/context.xml中修改或添加
<ResourceLink name="jndivalue" global="jndivalue" type="javax.sql.DataSource"/>
4,tomcat中,conf/server.xml中 <GlobalNamingResources> </GlobalNamingResources>中添加
<Resource name="jndivalue" auth="Container"
type="com.jolbox.bonecp.BoneCPDataSource"
factory="org.apache.naming.factory.BeanFactory"
driverClass="oracle.jdbc.driver.OracleDriver"
username="" password=""
jdbcUrl=""
idleMaxAge="240"
idleConnectionTestPeriod="60"
partitionCount="3"
acquireIncrement="10"
minConnectionsPerPartition="10"
maxConnectionsPerPartition="20"
releaseHelperThreads="3"/>
这四部分的jndivalue最好是统一的，tomcat和工程的纽带是第三部分，如果想不一样，修改第三部分
如果是新建工程，tomcat也是新的，用这种方式的话，需要往tomcat中导入一些jar包

四 : Spring+MyBatis多数据源配置实现
最近用到了MyBatis配置多数据源，原以为简单配置下就行了，实际操作后发现还是要费些事的，这里记录下，以作备忘
不多废话，直接上代码，后面会有简单的实现介绍
jdbc和log4j的配置

这里就上面的实现做个简单解释，在我们配置单数据源时可以看到数据源类型使用了org.apache.commons.dbcp.BasicDataSource，而这个代码实现了javax.sql.DataSource接口
配置sqlSessionFactory时org.mybatis.spring.SqlSessionFactoryBean注入参数dataSource类型就是javax.sql.DataSource
实现多数据源的方法就是我们自定义了一个MultipleDataSource，这个类继承自AbstractRoutingDataSource，而AbstractRoutingDataSource继承自AbstractDataSource ，AbstractDataSource 实现了javax.sql.DataSource接口，所以我们的MultipleDataSource也实现了javax.sql.DataSource接口，可以赋值给sqlSessionFactory的dataSource属性
public abstract class AbstractRoutingDataSource extends AbstractDataSource implements InitializingBean { } public abstract class AbstractDataSource implements DataSource { }再来说下MultipleDataSource的实现原理，MultipleDataSource实现AbstractRoutingDataSource抽象类，然后实现了determineCurrentLookupKey方法，这个方法用于选择具体使用targetDataSources中的哪一个数据源
<bean id="multipleDataSource" class="com.cnblogs.lzrabbit.MultipleDataSource"> <property name="defaultTargetDataSource" ref="mySqlDataSource"/> <property name="targetDataSources"> <map> <entry key="mySqlDataSource" value-ref="mySqlDataSource"/> <entry key="sqlServerDataSource" value-ref="sqlServerDataSource"/> </map> </property> </bean>扩展：spring mybatis数据源 / mybatis多数据源配置 / mybatis数据源配置
可以看到Spring配置中multipleDataSource设置了两个属性defaultTargetDataSource和targetDataSources，这两个属性定义在AbstractRoutingDataSource，当MyBatis执行查询时会先选择数据源，选择顺序时现根据determineCurrentLookupKey方法返回的值到targetDataSources中去找，若能找到怎返回对应的数据源，若找不到返回默认的数据源defaultTargetDataSource，具体参考AbstractRoutingDataSource的源码
public abstract class AbstractRoutingDataSource extends AbstractDataSource implements InitializingBean { private Map<Object, Object> targetDataSources; private Object defaultTargetDataSource; /** * Retrieve the current target DataSource. Determines the * {@link #determineCurrentLookupKey() current lookup key}, performs * a lookup in the {@link #setTargetDataSources targetDataSources} map, * falls back to the specified * {@link #setDefaultTargetDataSource default target DataSource} if necessary. * @see #determineCurrentLookupKey() */ protected DataSource determineTargetDataSource() { Assert.notNull(this.resolvedDataSources, "DataSource router not initialized"); Object lookupKey = determineCurrentLookupKey(); DataSource dataSource = this.resolvedDataSources.get(lookupKey); if (dataSource == null && (this.lenientFallback || lookupKey == null)) { dataSource = this.resolvedDefaultDataSource; } if (dataSource == null) { throw new IllegalStateException("Cannot determine target DataSource for lookup key [" + lookupKey + "]"); } return dataSource; } /** * Determine the current lookup key. This will typically be * implemented to check a thread-bound transaction context. * <p>Allows for arbitrary keys. The returned key needs * to match the stored lookup key type, as resolved by the * {@link #resolveSpecifiedLookupKey} method. */ protected abstract Object determineCurrentLookupKey();
............. }在动态切换数据源方法时选择了AOP方式实现，这里实现的简单粗暴，具体应用时根据实际需要灵活变通吧
题外话，这里提下SqlServer驱动选择的问题，目前SqlServer的驱动主要有微软的官方驱动和JTDS驱动两种，关于这两个驱动我做过测试，批量更新，在小数据量(100以下)时，JTDS相对微软驱动性能稍微高一点点，在数据量增大时几万到上百万时，微软驱动有着明显优势，所以若对性能比较敏感，建议使用微软驱动，否则随意
微软驱动在Maven库找不到，这点比较郁闷，若使用maven的话还得先安装到本地，这点很不爽
JTDS使用比较方便Maven直接引用即可
