目录结构

这句话的意思是找不到这个mapper.xml对应的java类
解决办法在启动类上加上
@MapperScan("com.itsm.email.dao")
必须指定到dao这一级目录，连同java类一同扫描进入，否则不会生效
到此，启动没问题，但是访问时报错
Invalid bound statement (not found): com.itsm.email.dao.AreaMapper.find
怀疑是mapper文件没有指定，在application.properties中加入
mybatis.mapper-locations=classpath:com/itsm/email/dao/mapper/*.xml
还不行，推测是不是.xml没扫描进入，看下target文件夹果然没有
在pom build中加入
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/**</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
至此访问成功
