直接报错
Invalid bound statement (not found): com.keke.mapper.EmpMapper.Select5

感觉就是扫描不到 xml文件 (不知道是不是)
但是在配置文件却配置了
##配置数据源
spring:
datasource:
druid:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
username: root
password: 123456
max-active: 10 #最大活跃连接数
min-idle: 5 #小小的活跃连接数
validation-query: select 'x' #验证连接是否可用的sql
#监控页
stat-view-servlet:
enabled: true #开启数据源监控
login-username: keke
login-password: keke
allow: #允许连接的IP --白名单
deny: #不允许连接的IP --黑名单
url-pattern: /druid/*
#开启mybatis的配置
mybatis:
mapper-locations: classpath:mapper/*.xml
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl #配置sql控制台输出

在启动类上也配置了
@MapperScan(basePackages = {"com.keke.mapper"})

网上的常规方法都是试过了!有没有人指点下
