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:/D:/apache-maven/local-maven-repository/com/baomidou/mybatis-plus-core/3.3.2/mybatis-plus-core-3.3.2.jar!/com/baomidou/mybatisplus/core/MybatisConfiguration.class

It was loaded from the following location:

file:/D:/apache-maven/local-maven-repository/com/baomidou/mybatis-plus-core/3.3.2/mybatis-plus-core-3.3.2.jar

Action:

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

Process finished with exit code 1

下一句中MybatisSqlSessionFactoryBean如果修改为SqlSessionFactoryBean就能正常启动，好苦恼呀

    MybatisSqlSessionFactoryBean sqlSessionFactory = new MybatisSqlSessionFactoryBean();

Answer 1

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

这句话判断，可能是你的类路径下的 MyBatis 的 配置文件格式不正确，建议看看那个文件。
