- org.mybatis mybatis-spring x.x.x
- dataSource
- 是数据源配置，常用有DBCP，C3P0，Druid等
- mapperLocations
- 是指接口xml的文件配置，如果不配映射接口类文件(.java)和映射XML文件(.xml)需要放在相同的包下。
- 和mybatis-config.xml的mappers功能相似，两个不需要同时配。
- configLocation
- 不是必须的，如果没有全局配置文件可以去掉
-
官方多种方法
-
spring中显示的逐一注入，mapper很多的话就会麻烦
-
利用mybatis-spring提供的自动扫描机制mybatis:scan/
- <beans ... xmlns:mybatis="http://mybatis.org/schema/mybatis-spring" xsi:schemaLocation="... http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd">
<mybatis:scan base-package="org.mybatis.spring.sample.mapper" />
-
Bean配置MapperScannerConfigurer
-
@MapperScan
- @Configuration @MapperScan("org.mybatis.spring.sample.mapper") public class AppConfig { // ... }
