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，并修改相关配置。

1.mybatis中

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

<!-- 分页插件 -->
		<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

<!--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

<!--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。根据自己xml的实际路径修改

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

或者

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