我在堆栈溢出中找到了三个条目:

javax.validation.ValidationException:无法找到默认提供程序

javax.validation.ValidationException:无法找到默认提供程序

Spring MVC 3验证 - 无法找到默认提供程序

并且所有三个人都说将hibernate验证器添加到类路径中.当我这样做并仍然得到相同的错误时我该怎么办？

经过几个小时的谷歌和一些教程,我被打败了...事实并非我得到错误可以给我提示问题是什么,完全没有它们让我疯了!

以下代码有效,只是不应该!检查输入不是null或小于3个字符长的注释永远不会运行.在部署项目或写入名称变量时,它们也不会发出任何错误.

public class testBean
{
    @NotNull
    @Size(min=3)
    private String name;
}

public void test()
{
    System.out.println(name);
}

输入表格:

<h:form>
        <h:inputText value="#{testBean.name}" />
    <h:commandButton value="Send" action="#{testBean.test()}" />
</h:form>

我的猜测是,这是导致问题的tomcat,虽然我很确定我已经导入了所有必要的库.对于我正在使用的IDE,Eclipse也是如此.
