    通用Mapper配置 主要配置

    通用Mapper插件网址:https://github.com/abel533/Mapper

    可以放在 utils包中

    public interface MyMapper<T> extends Mapper<T>, MySqlMapper<T> {
        //FIXME 特别注意,该接口不能被扫描到,否则会出错
    }
    
    

    这里实现一个自己的接口,继承通用的mapper,关键点就是这个接口不能被扫描到,不能跟dao这个存放mapper文件放在一起。
    最后在启动类中通过MapperScan注解指定扫描的mapper路径:

    @SpringBootApplication
    @EnableTransactionManagement  // 启注解事务管理,等同于xml配置方式的 <tx:annotation-driven />
    @MapperScan(basePackages = "com.dudu.dao", markerInterface = MyMapper.class)
    public class Application {
    
        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }
    }
    

    MyBatis Generator配置

    mybatis-generator.xml文件,该配置文件用来自动生成表对应的Model,Mapper以及xml,该文件位于src/main/resources下面

            <table tableName="LEARN_RESOURCE" domainObjectName="LearnResource" enableCountByExample="false"
                   enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
                   selectByExampleQueryId="false">
                <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
            </table>
        </context>
    </generatorConfiguration>
    

    其中tk.mybatis.mapper.generator.MapperPlugin很重要,用来指定通用Mapper对应的文件,这样我们生成的mapper都会继承这个通用Mapper

    • 可以直接通过命令:mvn mybatis-generator:generate
    • 通用maven 插件形式

    生成代码如下:

    domain

    @Table(name = "learn_resource")
    public class LearnResource {
        /**
         * ID
         */

        private Long id;
    
        /**

         */
        private String author;

        private String title;

        public void setId(Long id) {
            this.id = id;
        }
    
        /**

        public String getAuthor() {
            return author;
        }
    
        /**

    service 没有被事物管理

    • 在 业务 service 类上加 @Transactional 或 方法上加 @Transactional 即可,数据库连接将被事物管理
