使⽤Mybatis-Plus的SqlSessionFactory问题

前些⽇⼦⼯作中出现⼀个问题，项⽬中使⽤了MybatisPlus，然后出现了⼀个问题，Druid的其他的配置都可以正常使⽤，但是配置的SqlSessionFactory这个bean不能被加载，我在这个bean中加载的l⽂件也不能被加载，因为代码⾥使⽤了进⾏数据库的⾃动分页，到问题后在这⾥mark⼀下。

其实这⾥不能加载的原因是因为MybatisPlus中⾃定义了MybatisSqlSessionFactoryBean这个类，⽽这个

类是实现了接⼝FactoryBean<SqlSessionFactory>, InitializingBean, ApplicationListener<ApplicationEvent>，⽽在mybatis中有⼀个类也实现了这些接⼝，SqlSessionFactoryBean，所以在mybatisplus的配置⽂件中配置SqlSessionFactoryBean时需要换成mybatisplus中⾃定义的这个类MyBatisSqlSessionFactoryBean，并在类中加载对应的l⽂件。

贴⼀下这两个类的源码，看⼀眼就明⽩了

springboot+mybatis-plus报错Property'sqlSessionFactory'or'sqlSessionTemplate'are required 报错信息：

…

Caused by: java.lang.IllegalArgumentException: Property ‘sqlSessionFactory' or ‘sqlSessionTemplate' are

解决⽅案：

添加jar包：

<groupId&batis.spring.boot</groupId>

<artifactId>mybatis-spring-boot-starter</artifactId>

</dependency>

以上为个⼈经验，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
