springboot+mybatis-plus集成报错Property ‘sqlSessionFactory‘ or ‘sqlSessionTemplate‘ are required等问题

• 尝试网上众多方法后，仍无法解决。提供一种思路，mybatis-plus版本问题.

报错：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [com/baomidou/mybatisplus/autoconfigure/MybatisPlusAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is java.lang.IllegalStateException: Cannot enable lazy loading because Javassist is not available. Add Javassist to your classpath.

报错之前的pom.xml

com.baomidou
mybatis-plus-boot-starter
3.0.5

更改mybatis-plus版本，启动项目，运行成功。

    
            com.baomidou
            mybatis-plus-boot-starter
            3.1.0
