MyBatise中容易忽略的配置——驼峰转换

1、实例化Configuration对象并将其mapUnderscoreToCamelCase属性设为true

public class WrapAndChangeConfigureSqlSessionFactory extends SqlSessionFactoryBean {

    @Override

    public void afterPropertiesSet() throws Exception {

        super.afterPropertiesSet();

        SqlSessionFactory sqlSessionFactory = super.getObject();

        Configuration configuration = sqlSessionFactory.getConfiguration();

        configuration.setMapUnderscoreToCamelCase(true);

    }

}

2、在spring boot的配置文件application.properties中，加入配置项：

1 mybatis.configuration.mapUnderscoreToCamelCase=true
2 或
3 mybatis.configuration.map-underscore-to-camel-case=true
