同学好，是不是映射配置不对呀，对比一下SSM形态和后面的springboot形态，控制台输出的sql是否一致，然后同学说的集合为null，是否进行过比对，可以提供一下相关的截图，最好有SSM和springboot的比较。然后对比下dao的配置

SessionFactoryConfiguration.java

package com.imooc.o2o.config.dao;

import java.io.IOException;

import javax.sql.DataSource;

import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.core.io.support.ResourcePatternResolver;

@Configuration
public class SessionFactoryConfiguration {
	// mybatis-config.xml配置文件的路径
	private static String mybatisConfigFile;

	@Value("${mybatis_config_file}")
	public void setMybatisConfigFile(String mybatisConfigFile) {
		SessionFactoryConfiguration.mybatisConfigFile = mybatisConfigFile;
	}

	// mybatis mapper文件所在路径
	private static String mapperPath;

	@Value("${mapper_path}")
	public void setMapperPath(String mapperPath) {
		SessionFactoryConfiguration.mapperPath = mapperPath;
	}

	// 实体类所在的package
	@Value("${type_alias_package}")
	private String typeAliasPackage;

	@Autowired
	private DataSource dataSource;

	/**
	 * 创建sqlSessionFactoryBean 实例 并且设置configtion 设置mapper 映射路径 设置datasource数据源
	 * 
	 * @return
	 * @throws IOException
	 */
	@Bean(name = "sqlSessionFactory")
	public SqlSessionFactoryBean createSqlSessionFactoryBean() throws IOException {
		SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
		// 设置mybatis configuration 扫描路径
		sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(mybatisConfigFile));
		// 添加mapper 扫描路径
		PathMatchingResourcePatternResolver pathMatchingResourcePatternResolver = new PathMatchingResourcePatternResolver();
		String packageSearchPath = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX + mapperPath;
		sqlSessionFactoryBean.setMapperLocations(pathMatchingResourcePatternResolver.getResources(packageSearchPath));
		// 设置dataSource
		sqlSessionFactoryBean.setDataSource(dataSource);
		// 设置typeAlias 包扫描路径
		sqlSessionFactoryBean.setTypeAliasesPackage(typeAliasPackage);
		return sqlSessionFactoryBean;
	}
