Springboot集成mybatis

Posted 2022-11-02 naixin007

1.引入依赖

        <!-- 通用Mapper启动器 -->
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
        </dependency>

2.定义mapper接口

public interface CategoryMapper extends Mapper<Category> 

3.启动类添加包扫描注解

@MapperScan("com.viuman.item.mapper")

或者在每个mapper接口上都加

@org.apache.ibatis.annotations.Mapper

4.基本查询

        Category category = new Category();
        category.setParentId(pid);
        return categoryMapper.select(category);
