我看到有一百万个主题在谈论这个问题，但没有一个与我的问题相符，而且这里是：
我的查询将以下结果列入清单：
- Caixa Economica Federal
- ASSOCIAÇÃODOSFRANQUEADOS DA REDE DE LANCHOLETES GIRAFFAS
尝试按h:selectOneMenu中的第一项搜索时，一切正常。但是当我尝试按列表中的第二项搜索时，我收到以下错误：
j_idt49：advertiserName：验证错误：值无效
这真的很奇怪，至少在我看来，我看到的所有先前的答案都没有任何意义，如果你考虑到某些值，搜索工作正常。
以下是我的代码：

答案 0 :(得分：4)
您忘记根据the contract在equals()班级中实施hashCode()和Matches。 JSF正在使用它来匹配所选项目和可用项目。否则，只有new运算符创建的项目才会被视为与其自身相等，但new运算符创建的两个单独的实例永远不会被视为相等，即使它们在技术上可能基于其内部相等属性。
如果您的Matches类的id字段代表技术数据库标识符，那么应该这样做：
@Override
public boolean equals(Object other) {
return (id != null && other != null && getClass() == other.getClass())
? id.equals(((Matches) other).id)
: (other == this);
}
@Override
public int hashCode() {
return (id != null)
? (getClass().hashCode() + id.hashCode())
: super.hashCode();
}
此外，转换器的getAsObject()方法看起来当前形式可疑。它完全忽略controller并直接返回原始未转换value。该方法应该将获得的表示Matches实例的ID的字符串转换为具体的Matches实例。
它应该看起来像这样：
public Object getAsObject(FacesContext facesContext, UIComponent component, String value) {
if (value == null || value.length() == 0) {
return null;
}
Integer id = getKey(value);
Matches matches = getItSomehowBasedOn(id);
return matches;
}
