报错的原因以及解决方法

mybatis包冲突，导致依赖包使用的不是mybatis plus的包

1. 检查是否引入了Mybatis plus依赖
   官网中，引入的mybatis plus依赖如下

<dependency>
    <groupId>com.baomidougroupId>
    <artifactId>mybatis-plus-boot-starterartifactId>
    <version>3.5.1version>
dependency>


<dependency>
    <groupId>com.baomidougroupId>
    <artifactId>mybatis-plusartifactId>
    <version>3.5.1version>
dependency>

引入 MyBatis-Plus 之后请不要再次引入 MyBatis 以及 MyBatis-Spring，以避免因版本差异导致的问题。

2. 删除导致冲突的mybatis其它依赖
   检查pom文件中是否引入了其它mybatis的依赖项，如果有以下依赖，可以直接注释掉：

<dependency>
    <groupId>org.mybatis.spring.bootgroupId>
    <artifactId>mybatis-spring-boot-starterartifactId>
    <version>1.3.0version>
dependency>



<dependency>
    <groupId>org.mybatisgroupId>
    <artifactId>mybatis-springartifactId>
    <version>1.3.1version>
dependency>

<dependency>
    <groupId>org.mybatisgroupId>
    <artifactId>mybatisartifactId>
    <version>3.4.4version>
dependency>

sqlSessionFactory不是mybatis plus的SqlSessionFactory

1. spring boot中的sqlSessionFactory bean配置

@Configuration
public class MybatisPlusConfig {
	@Value("${mybatis.mapper-locations}")
	private String mapperLocations;
	
	// spring boot
	@Bean
	public SqlSessionFactory sqlSessionFactory(DataSource dataSource)
	        throws Exception {
	    final MybatisSqlSessionFactoryBean sessionFactory = new MybatisSqlSessionFactoryBean();
	    sessionFactory.setDataSource(dataSource);
	    sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(mapperLocations));
	    return sessionFactory.getObject();
	}
}

2. spring boot中的sqlSessionFactory bean配置

<bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="configLocation" value="classpath:/mybatis.xml"/>
    <property name="mapperLocations">
        <array>
            <value>classpath*:/mapper/**/*.xmlvalue>
        array>
    property>
bean>
