When integrating Spring+Mybatis framework, data is queried according to conditions and an exception occurs

Caused by: : There is no getter for property named 'sname' in 'class '

document:

<select  parameterType="string" resultMap="userinfoMap">
		select * from userinfo where sname like '%${sname}%'

public List<Userinfo> findAll(@Param("sname") String sname);
