Spring整合MyBatis的applicationContext.xml配置文件.使用了c3p0

Spring整合了Mybatis之后的applicationContext.xml.刚学了这两个,整理了一下配置文件.使用不同的连接池(数据源)只需要换不同的连接池实现类,各个连接池对于4大参数的命名可能不同,不过结构大体是相同的.

如配置 datasource 四种方式,换不同的连接池(数据源)只用改<!-- 配置数据源(连接池) -->

附:db.properties中内容,这个文件放在classpath下

db.driver = com.mysql.jdbc.Driver
db.url = jdbc:mysql://localhost:3306/bookstore
db.username = root
db.password =(数据库密码)
