Action:

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
