SpringBoot整合mybatis-plus

 

一、新建一個Spring Initializr項目

 

二、添加項目信息

 

 

三、選擇需要的依賴

 

四、新建成功修改pom文件

添加mybatis-plus和其他依賴文件添加mybatis反向工程插件如下代碼

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

</project>

 

五、建立工程目錄

 

六、使用自動生成代碼插件生成接口、xml、實體類

 

如上圖所示配置好接口、xml、實體類的生成路徑，雙擊mybatis-generator插件生成文件

 

七、配置mybatis-plus掃描xml路徑

 

八、配置註解掃描mapper文件路徑

 

 

九、測試查詢數據

 

十、分頁

在mapper文件中寫一個分頁的方法，在xml文件中添加一個查詢sql，運用spring boot test中調用測試

 

 

 

測試結果：
