"Cannot determine value type from string '-3~0%'"是一个错误消息,它表明在处理数据库结果集时无法确定字符串“-3~0%”的值类型。这个错误通常有几个可能的原因。首先,可能是因为设置了有参构造函数但没有无参构造函数,可以尝试添加一个无参构造函数来解决这个问题。其次,可能是传入参数的类型不正确,比如数据库中是int类型,而您传入的却是String类型,需要确保数据类型一致。另外,也可能是输出参数的类型不正确,比如数据库查询结果是对象集合,而您设置的输出却是int或String类型。您可以检查mapper接口实现类,确保传入参数和调用方法正确。另外,还可以检查数据库中的数据类型是否正确。总之,这个问题的解决方案可能需要综合考虑多个因素。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
