关于在Spring MVC中整合JPA是在我的上一篇关于spring mvc基本配置基础上进行的，所以大家先参考一下我的上一篇文章：
接下来是需要新添加的一些文件：
jdbc.properties：
jdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc\:mysql\://localhost\:3306/tmos?useUnicode\=true&characterEncoding\=utf-8&autoReconnect\=truejdbc.user=rootjdbc.password=rootjdbc.dialect=org.hibernate.dialect.MySQL5Dialectjdbc.show_sql=falsejdbc.format_sql=true#jdbc.dialect=org.hibernate.dialect.MySQLInnoDBDialectjdbc.initialPoolSize=2jdbc.maxPoolSize=200jdbc.batch_size=20jdbc.hbm2ddl.auto=updatejdbc.query.substitutions=true 1, false 0, yes ''Y'', no ''N''jpaConfig.xml:

，而消极的人则在每个机会都看到某种忧患。
