160929、各数据库连接配置与maven依赖安装
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。
MySQL
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 |
Oracle
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 |
SQL Server
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
手动安装Maven依赖包
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.
