用Jersey构建RESTful服务6-Jersey+SQLServer+Hibernate4.3

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

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>  

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 executeINFO: HHH000232: Schema update completeHibernate: insert into RestDemo.T_USER (userName, age, USERID) values (?, ?, ?)三月 26, 2014 3:38:43 下午 org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptionsWARN: SQL Error: 208, SQLState: S0002三月 26, 2014 3:38:43 下午 org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptionsERROR: 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">
