进行Spring整合Mybatis时，发生的Bug；

看Log：

解决:自己写的BUG：There is no getter for property named 'uesrName' in 'class com.smbms.pojo.User'，写错单词。

（1）select标签的sql语句，与映射实体类的成员变量对应不上：

 <select id="getUserList" parameterType="com.smbms.pojo.User" resultMap="userlist">select u.* ,r.roleName from smbms_user,u smbms_role rwhere u.userName like CONCAT('%',#{uesrName},'%')and u.userRole = #{userRole} and u.userRole = r.id</select>

（2）从报错的“no getter for property ”可知：这个对应关系是通过getter()方法访问器得到的。

 private String userName;public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}
