Springboot项目中Mybatis升级Mybatis-plus依赖冲突问题

原项目系统中已经引入了 Mybatis 和 pagehelper ，当引入Mybatis-plus 后启动项目报错 SqlSessionFactory 错误，排查原因后为依赖冲突导致，需排除部分jar包

1. Mybatis中

<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper-spring-boot-starter</artifactId>
    <version>2.1.5</version>
原Mybatis中需排除下面2个依赖
    <exclusions>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2. pagehelper 中

<dependency>
    <groupId>com.github.pagehelper</groupId>
    <artifactId>pagehelper-spring-boot-starter</artifactId>
    <version>1.2.3</version>
需排除下面包
    <exclusions>
        <exclusion>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </exclusion>
    </exclusions>
</dependency>
3.引入Mybatis-plus

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.3.2</version>
</dependency>

4.引入autoconfigure

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-autoconfigure</artifactId>
    <version>2.1.4</version>
</dependency>

5. 修改配置文件，将原 mybatis 改成 mybatis-plus

mybatis-plus:
  mapper-locations: classpath*:/mapper/*.xml,classpath*:/mapper/**/*.xml
  configuration:
    mapUnderscoreToCamelCase: true
