最近做的项目都是maven的，据说maven是个东西。把依赖的jar文件的事情都委托出去辣！试着用了一下哈，效果还可以！
今天做了数据库配置这一块，特意把相关的东西总结出来，以备不时之需。
db driver maven dependency
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.0.5</version>
hibernate.properties |
hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.url=jdbc:mysql://localhost/trails?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=utf-8
hibernate.connection.username=root
hibernate.connection.password=
hibernate.hbm2ddl.auto=update
|
db driver maven dependency
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.2.0</version>
</dependency>
|
hibernate.properties
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect
hibernate.connection.driver_class=oracle.jdbc.OracleDriver
hibernate.connection.url=jdbc:oracle:thin:@localhost:1521:XE
hibernate.connection.username=system
hibernate.connection.password=system
hibernate.hbm2ddl.auto=update
# The Oracle JDBC driver doesn‘t like prepared statement caching very much.
hibernate.statement_cache.size=0
# or baching with BLOBs very much.
hibernate.jdbc.batch_size=0
# After a while, Oracle throws this exception: too many open cursors
# Disable PreparedStatement caching for the connection pool too.
# http://www.hibernate.org/120.html#A10
hibernate.dbcp.ps.maxIdle = 0
# Stoping hibernate from using the column-names in queries to retrieve data from the resultsets
# More info in http://www.jroller.com/page/dashorst?entry=hibernate_3_1_something_performance1
hibernate.jdbc.wrap_result_sets=true

db driver maven dependency
<dependency>
<groupId>net.sourceforge.jtds</groupId>
<artifactId>jtds</artifactId>
<version>1.2</version>
</dependency>
hibernate.properties
hibernate.dialect=org.hibernate.dialect.SQLServerDialect
hibernate.connection.driver_class=net.sourceforge.jtds.jdbc.Driver
hibernate.connection.url=jdbc:jtds:sqlserver://localhost:1433/trails
hibernate.connection.username=sa
hibernate.connection.password=
hibernate.hbm2ddl.auto=update
例如要安装这样一个依赖到maven本地仓库：
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
mvn install:install-file -Dfile=sqljdbc4-3.0.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=3.0 -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X:\Documents and Settings\%USER%\.m2\repository\com\microsoft\sqlserver\sqljdbc4\3.0 中即可.
