Spring+Mybatis 查询所有数据时发生异常：org.apache.ibatis.reflection.ReflectionException: There is no getter for

Spring+Mybatis框架整合时,根据条件查询数据，发生异常

Caused by: org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'sname' in 'class java.lang.String'

userinfoMapper.xml文件：

		select * from userinfo where sname like '%${sname}%'
	

UserinfoMapper接口:

public List findAll(String sname);

解决方法:在参数前加@Param标签

public List findAll(@Param("sname") String sname);
