一、总体说明
本例运行演示了用Jersey构建RESTful服务中,如何同过Hibernate将数据持久化进SQLServer的过程
二、环境
1.上文的项目RestDemo
2.SQLServer2005三、配置
与上文mysql的配置不同点主要在hibernate.cfg.xml文件;
配置如下:
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property> <property name="connection.url">jdbc:jtds:sqlserver://192.168.1.10:1433;RestDemo</property> <property name="connection.username">sa</property> <property name="connection.password">aA123456</property> <property name="hibernate.default_schema">RestDemo</property> <!-- JDBC connection pool (use the built-in) --> <property name="connection.pool_size">1</property> <!-- SQL dialect --> <property name="dialect">org.hibernate.dialect.SQLServerDialect</property> <!-- Enable Hibernate's automatic session context management --> <property name="current_session_context_class">thread</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hbm2ddl.auto">update</property> <mapping resource="com/waylau/rest/bean/User.hbm.xml"/> </session-factory> </hibernate-configuration>四、问题
可能会出现如下错误
ERROR: 指定的架构名称 "RestDemo" 不存在,或者您没有使用该名称的权限。 三月 26, 2014 3:38:43 下午 org.hibernate.tool.hbm2ddl.SchemaUpdate execute INFO: HHH000232: Schema update complete Hibernate: insert into RestDemo.T_USER (userName, age, USERID) values (?, ?, ?) 三月 26, 2014 3:38:43 下午 org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions WARN: SQL Error: 208, SQLState: S0002 三月 26, 2014 3:38:43 下午 org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions ERROR: 对象名 'RestDemo.T_USER' 无效。
将配置文件中的“hibernate.default_schema”值修改为如下即可:
<property name="hibernate.default_schema">RestDemo.dbo</property>
或者去掉上面的配置,在“User.hbm.xml”修改如下
<class name="User" table="T_USER" schema="RestDemo.dbo">
