在mappers下边是mybatis的xml文件，启动的时候出现错误：
DEBUG o.m.spring.SqlSessionFactoryBean - Property 'configLocation' not specified, using default MyBatis Configuration
解决方式如下：
|
1 2 3 4 5 |
< bean id = "sessionFactory" class = "org.mybatis.spring.SqlSessionFactoryBean" > < property name = "dataSource" ref = "dataSource" /> < property name = "mapperLocations" value = "classpath:mybatis/mappers/*.xml" /> < property name = "configLocation" value = "classpath:spring/persistence-context.xml" /> </ bean > |
在sessionFactory下加入：
|
1 |
< property name = "configLocation" value = "classpath:spring/persistence-context.xml" /> |
添加 persistence-context.xml 的位置即可，或者所有的文件都在一个文件即可
