這篇文章主要介紹了使用Mybatis-Plus時(shí)的SqlSessionFactory問(wèn)題及處理方式，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教

使用Mybatis-Plus的SqlSessionFactory問(wèn)題

前些日子工作中出現(xiàn)一個(gè)問(wèn)題，項(xiàng)目中使用了MybatisPlus，然后出現(xiàn)了一個(gè)問(wèn)題，Druid的其他的配置都可以正常使用，但是配置的SqlSessionFactory這個(gè)bean不能被加載，我在這個(gè)bean中加載的mybatis-config.xml文件也不能被加載，因?yàn)榇a里使用了攔截器進(jìn)行數(shù)據(jù)庫(kù)的自動(dòng)分頁(yè)，找到問(wèn)題后在這里mark一下。

其實(shí)這里不能加載的原因是因?yàn)镸ybatisPlus中自定義了MybatisSqlSessionFactoryBean這個(gè)類，而這個(gè)類是實(shí)現(xiàn)了接口FactoryBean<SqlSessionFactory>, InitializingBean, ApplicationListener<ApplicationEvent>，而在mybatis中有一個(gè)類也實(shí)現(xiàn)了這些接口，SqlSessionFactoryBean，所以在mybatisplus的配置文件中配置SqlSessionFactoryBean時(shí)需要換成mybatisplus中自定義的這個(gè)類MyBatisSqlSessionFactoryBean，并在類中加載對(duì)應(yīng)的mybatis-config.xml文件。

貼一下這兩個(gè)類的源碼，看一眼就明白了

springboot+mybatis-plus報(bào)錯(cuò)Property'sqlSessionFactory'or'sqlSessionTemplate'are required

報(bào)錯(cuò)信息：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘TBaseAuthController': Unsatisfied dependency expressed through field ‘tBaseAuthService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘TBaseAuthServiceImpl': Unsatisfied dependency expressed through field ‘baseMapper'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘TBaseAuthMapper' defined in file [D:\瀏覽器下載\myframe\yss-server\target\classes\com\yss\cn\modules\mapper\TBaseAuthMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property ‘sqlSessionFactory' or ‘sqlSessionTemplate' are required
…
Caused by: java.lang.IllegalArgumentException: Property ‘sqlSessionFactory' or ‘sqlSessionTemplate' are required

解決方案：

添加jar包：

<dependency>
 <groupId>org.mybatis.spring.boot</groupId>
 <artifactId>mybatis-spring-boot-starter</artifactId>
 <version>1.3.2</version>
</dependency>

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
