web.xml配置

<!-- shiro过滤器定义 -->
<filter>
  <filter-name>shiroFilter</filter-name>
  <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  <init-param>
    <!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 -->

Mapper中新增

<select id="queryByName" resultType="com.javaxl.ssm.model.ShiroUser" parameterType="java.lang.String">
  select
  <include refid="Base_Column_List" />
  from t_shiro_user
  where userName = #{userName}
