Mybatis-plus 定义SqlSessionFactory_mybatisplus sqlsessionfactory

最近写ssm项目升级为mybatis-plus发现一个问题,就是在ssm中使用mybatis-plus, mapper和xml文件可以正常生成,但是mybatis-plus自带的增删改查方法用不了,
报错如下

查找了半天,发现是SqlSessionFactory的问题,Mybatis-plus 和Mybatis 是兼容的。

所以网上的配置 mybatis 的SqlSessionFactory 的方法基本上可行，但是对于mybatis-plus 的一些特性会丢失, 自带的增删改查方法用不了
原配置如下

package com.it.car.config;

import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean;
import com.github.pagehelper.PageInterceptor;
import com.zaxxer.hikari.HikariDataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.context.annotation.*;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import java.io.IOException;
import java.util.Properties;

        //可选配置,设置别名
        sqlSessionFactoryBean.setTypeAliasesPackage("com.it.car.outlet.po");
        return sqlSessionFactoryBean;

    }

        //扫描器配置接口扫描包范围
        configurer.setBasePackage("com.it.car.outlet.dao");

要想使用Mybatis-plus 自带增删改查方法,需要将
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
换成mybatis-plus
修改配置如下

package com.it.car.config;

import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean;
import com.github.pagehelper.PageInterceptor;
import com.zaxxer.hikari.HikariDataSource;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.context.annotation.*;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import java.io.IOException;
import java.util.Properties;

/**
 * 配置类作用：
 * 1.开启service层包扫描
 * 2.service注入dao对象
 * 3.注入事务管理器对象
 */
@Configuration
@ComponentScan("com.it.car.service")
//开启spring AOP 代理 proxyTargetClass 默认false jdk 启用  true cglib
@EnableAspectJAutoProxy(proxyTargetClass = true)
//引入数据库连接池配置信息
@Import({SpringDao.class,RedisConfig.class})
public class SpringService {
    @Bean
    public MybatisSqlSessionFactoryBean mybatisSqlSessionFactoryBean(HikariDataSource hikariDataSource){
        MybatisSqlSessionFactoryBean mybatisSqlSessionFactoryBean = new MybatisSqlSessionFactoryBean();
        //配置: 核心配置文件url地址
        mybatisSqlSessionFactoryBean.setConfigLocation(new ClassPathResource("mybatis-config.xml"));
        //配置：sql映射文件的url地址，如果sql映射文件和接口的文件同名同目录，这行配置可以省略不写
        /*sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver()
                .getResources("classpath:com/it/dao/*.xml"));*/
        //配置分页插件

        //设置分页插件的属性
        Properties properties = new Properties();
        properties.setProperty("helperDialect","mysql");
        properties.setProperty("reasonable","true");
        pageInterceptor.setProperties(properties);

        mybatisSqlSessionFactoryBean.setPlugins(pageInterceptor);
        // 将资源设置到 sqlSessionFactoryBean 的 mapperLocations
        try {
            mybatisSqlSessionFactoryBean.setMapperLocations(
                    new PathMatchingResourcePatternResolver().getResources("classpath:/mappers/**/*.xml"));
        } catch (IOException e) {

        //可选配置,设置别名
        mybatisSqlSessionFactoryBean.setTypeAliasesPackage("com.it.car.outlet.po");
        return mybatisSqlSessionFactoryBean;

    }
