activiti7整合mybatisPlus报错：

java.lang.NoSuchMethodError: ‘org.apache.ibatis.scripting.LanguageDriver org.apache.ibatis.session.Configuration.getLanguageDriver(java.lang.Class)’

activiti与mybatis冲突，将activiti依赖修改为：

        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-spring-boot-starter</artifactId>
            <version>7.1.0.M6</version>
            <exclusions>
                <exclusion>
                    <artifactId>mybatis</artifactId>
                    <groupId>org.mybatis</groupId>
                </exclusion>
            </exclusions>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.1</version>
        </dependency>

Ps：两者mybatis版本需要保持一致，具体版本信息可从启动错误日志中获取。
