问题描述：

​ mybatis-plus整合flowable的时候发现springboot启动失败了

异常信息如下：

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method com.baomidou.mybatisplus.core.MybatisConfiguration.getLanguageDriver(Ljava/lang/Class;)Lorg/apache/ibatis/scripting/LanguageDriver; but it does not exist. Its class, com.baomidou.mybatisplus.core.MybatisConfiguration, is available from the following locations:

    jar:file:/Users/j/javaTool/publicMaven/mavenRepository/com/baomidou/mybatis-plus-core/3.1.1/mybatis-plus-core-3.1.1.jar!/com/baomidou/mybatisplus/core/MybatisConfiguration.class

It was loaded from the following location:

    file:/Users/j/javaTool/publicMaven/mavenRepository/com/baomidou/mybatis-plus-core/3.1.1/mybatis-plus-core-3.1.1.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of com.baomidou.mybatisplus.core.MybatisConfiguration

解决方案：

​ 在flowable的包下新增

            <exclusions>
                <exclusion>
                    <artifactId>mybatis</artifactId>
                    <groupId>org.mybatis</groupId>
                </exclusion>
            </exclusions>

问题产生原因：

​ 使用mavenHelper分析，由于项目中使用了flowable中底版本mybatis导致mybatis-plus中需要使用的方法在该版本中没有。排除flowable的mybatis，使用mybatis-plus中带的就行了
