最佳答案

配置扫描mapper文件的路径了吗?

例如:
spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
url: jdbc:mysql://localhost:3306/数据库名?useSSL=false&useUnicode=true&characterEncoding=utf-8
username: root
password: wubiaowp
driver-class-name: com.mysql.jdbc.Driver
initialSize: 5
maxActive: 200
minIdle: 5
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: select 'x'
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
maxOpenPreparedStatements: 20

mybatis:
mapper-locations: classpath:mapper/*_mapper.xml
type-aliases-package: com.util.model

springboot不是支持注解吗，@MapperScan("com.llfy.demo.dao")

sql使用注解是没有问题的，使用xml文件就会有这个错

@刘凌枫羽: 你这个配置是扫描dao接口的; 自己看一下呀, @MapperScan("com.llfy.demo.dao"); 你的mapper文件是在resources/mapper下面的
你得告诉spring 去哪里把mapper文件加载进来对吧?
