Spring整合MyBatis 是将Spring和MyBatis应用到一个项目中。MyBatis 提供数据库相关的操作,完成对象数据和关系数据的转换。Spring完成项目的管理,通过IOC和AOP完成依赖注入,事务管理等操作。 本示例采用idea开发。 创建实体类: 1 2 3 4 5 6 7 packagecom.project.bean; publicclassManBean { privateintid; private...
@Import注解是将其他配置类中的文件导入到Spring的配置类中 package com.hh.config; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Import; import org.springframework.context.annotation.PropertySour...

Spring整合MyBatis使用到了mybatis-spring,在配置mybatis映射文件的时候,一般会使用MapperScannerConfigurer,MapperScannerConfigurer会自动扫描basePackage指定的包,找到映射接口类和映射XML文件,并进行注入。配置如下: <!-- 数据源 --> <beanid="dataSource"class="com.mchange.v2.c3p0.ComboPooledDataSource"destroy...
