SpringBoot3匹配Mybatis3的錯(cuò)誤與解決方案

更新時(shí)間：2025年08月16日 10:25:32 作者：RR1335

文章指出SpringBoot3與MyBatis3兼容性問(wèn)題,因未更新MyBatis-Plus依賴(lài)至SpringBoot3專(zhuān)用坐標(biāo),導(dǎo)致類(lèi)沖突,解決方案是替換pom中的依賴(lài)為`mybatis-plus-spring-boot3-starter:3.5.12`,并排除舊版本核心庫(kù),確保版本一致性

SpringBoot3匹配Mybatis3的錯(cuò)誤與解決

mybatis-plus在pom文件中的出錯(cuò)

提到了 pom 文件的錯(cuò)誤。

mybatis在SpringBoot3

提供了一個(gè)新的坐標(biāo)：

<!-- https://mvnrepository.com/artifact/com.baomidou/mybatis-plus-spring-boot3-starter -->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
    <version>3.5.12</version>
</dependency>

https://mvnrepository.com/artifact/com.baomidou/mybatis-plus-spring-boot3-starter/3.5.12

如果沒(méi)有個(gè)更新到新坐標(biāo)

一樣會(huì)出錯(cuò)。
