maven用的比较多，所以自己去捣鼓了一下：以下是关于数据库配置的一块，把相关的内容张贴出来，以备不时之需
//MySql
配置文件(maven)：pom.xml
mysql mysql-connector-java 5.0.5
配置文件：(hibernat.properties)
hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
hibernate.connection.driver_calss=mysql.jdbc.Driver
hibernate.connection.url=jdbc:mysql://localhost:3306/trails?createDatabaseIfNotExist=true&o;useUnicode=ture&characterEncoding=utf-8
hibernate.connection.username=root
hibernate.connection.password=****
hibernate.connection.hbm2ddl.auto=update
//Oracle
配置文件(maven)
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.2.1</version>
</dependency>
配置文件：(hibernat.properties)
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect
hibernate.connection.driver_calss=oracle.jdbc.OracleDriver
hibernate.connection.url=jdbc:oracle:thin:@localhost:1521:XE
hibernate.connection.username=system
hibernate.connection.password=****
hibernate.connection.hbm2ddl.auto=update
//SQL Server
配置文件(maven)
<dependency>
<groupId>net.sourceforge.jtds</groupId>
<artifactId>jtds</artifactId>
<version>1.2</version>
</dependency>
配置文件：(hibernat.properties)
hibernate.dialect=org.hibernate.dialect.SQLServerDialect
hibernate.connection.driver_calss=net.sourceforge.jtds.jdbc.Driver
hibernate.connection.url=jdbc:jtds:sqlserver://localhost:1433/trails?createDatabaseIfNotExist=true&o;useUnicode=ture&characterEncoding=utf-8
hibernate.connection.username=sa
hibernate.connection.password=****
hibernate.connection.hbm2ddl.auto=update
//手动安装maven依赖包
1:将此依赖添加到项目的pom.xml
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>3.0</version>
</dependency>
2:在命令行中执行install命令 (有用)
mvn install:install-file -Dfile=mysql-connection-java-4.1.45-bin.jar -DgroupId=mysql-connection-java -DartifactId=mysql -Dversion=4.1.45 -Dpackaging=jar
3:将sqljdbc4-3.0.jar拷贝到此依赖安装目录
将sqljdbc4-3.0.jar拷贝到\Documents and Settings\%USER%\.m2\repository\com\microsoft\sqlserver\sqljdbc\4\3.0中即可
