hibernate spring 连接两个数据库

Question

如题，那位高手指导一下，怎么配置呢

Answer 1

可以配置两个数据源
或者在dataSource="" 这个地方不写数据库名称

Answer 2

配一个sessionFactory，不同sessionFactory获取的session执行的操作

Answer 3

要连接多个数据库可以建2个datasource和2个sessionfactory
最后在定义transactionManager的时候要用分布式的,如下:
<bean   id="transactionManager"   class="org.springframework.transaction.jta.JtaTransactionManager"   >

Answer 4

配置两个SessionFactory，然后注入到不同的DAO，DAO要使用哪个数据库连接不要搞错了

Answer 5

这个很简单的啊,首先在jdbc.properties里面列出你要连接的数据库的一些信息,如url,username,password之类,当然键是不能重复的,然后xml解析的时候根据properties里面的信息就可以生成两个不同的数据源就可以了

Answer 6

不行呀，服务器启动没问题，但一进行操作就
会报org.springframework.jdbc.BadSqlGrammarException: StatementCallback;
应该还是边库的问题

Answer 7

我的配置文件是这样的

Answer 8

如果需要跨库事务的话，需要ejb容器来支持jta
