Property ‘sqlSessionFactory‘ or ‘sqlSessionTemplate‘ are required

报错信息: Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

1 导入mybatis-spring-boot-starter-test依赖

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

2 检查pom.xml配置的数据库版本与实际数据库版本是否一致,无用

3 降低spring-boot-starter-parent版本,删除maven仓库里面的jar包,重新导入

  <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
<!--        <version>2.2.2.RELEASE</version>-->
        <version>2.0.1.RELEASE</version>
        <relativePath/>
    </parent>

4 确认是否存在数据库连接池的包

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.21</version>
</dependency>

5 是否是本地仓库的jar冲突,删除所有jar包,重新下载
6 查看启动类是否有 @SpringBootApplication(exclude = DataSourceAutoConfiguration.class), 有则删除
