springboot3.5.4集成mybatisplus3.5.12遇到的问题

现场环境：

springboot：3.5.4

mybatisplus：3.5.12

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <version>3.5.4</version>
        </dependency>
        <!-- mybatis-plus 所需依赖  -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.12</version>
        </dependency>

运行时候报错：

其实问题就是版本冲突，mybatisplus3.5.12里自带的mybatis-spring版本是2.1.2的，但是springboot3.5.4依赖的mybatis-spring版本不能用怎么老的。

处理办法也简单，把mybatisplus3.5.12里自带的mybatis-spring排除，重新引入就行

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>

                </exclusion>
            </exclusions>
        </dependency>

        <!--    排除mybatis-plus-boot-starter里面的mybatis-spring，重新导入3.0版本    -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>

        </dependency>

刷新maven后启动成功。
