SpringBoot整合mybatis-plus

 

一、新建一个Spring Initializr项目

 

二、添加项目信息

 

 

三、选择需要的依赖

 

四、新建成功修改pom文件

添加mybatis-plus和其他依赖文件添加mybatis反向工程插件如下代码

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

 

五、建立工程目录

 

六、使用自动生成代码插件生成接口、xml、实体类

 

如上图所示配置好接口、xml、实体类的生成路径，双击mybatis-generator插件生成文件

 

七、配置mybatis-plus扫描xml路径

 

八、配置注解扫描mapper文件路径

 

 

九、测试查询数据

 

十、分页

在mapper文件中写一个分页的方法，在xml文件中添加一个查询sql，运用spring boot test中调用测试

 

 

 

测试结果：
