通过逆向工程将五张表生成对应的model、mapper

Usermapper

ShiroUser queryByName(@Param("uname") String uname);
  <select id="queryByName" resultType="com.huang.model.ShiroUser" parameterType="java.lang.String">
    select
    <include refid="Base_Column_List" />
    from t_shiro_user
    where username = #{uname}
  </select>
